www.theapiarist.org’s year

This is the second full year that this site has been running. Visitor numbers to the site wax (no pun intended) and wane with the beekeeping season – lower in the winter and higher in the summer. This is perhaps not unsurprising … the online forums are much the same, though there’s a lot less bickering here in the winter and no-ones actually been banned.¬†Yet ūüėČ

Posts

The site has been visited by beekeepers (or visitors, or at least robots¬†…¬†) from 132 countries over the course of the year. The most popular individual articles are on honey warming cabinets, Paynes poly nuc boxes, steam wax extractors and the one article I posted on the Saf Natura honey extractor (which continues to¬†perform¬†really well … the extractor, not the article). These were all originally posted in 2014 so have had time to permeate deep into the Googled-psyche of the internet. The most popular 2015 post was about avoiding – or removing – frosting in honey. Tim Foden posted some useful additional comments on this when I recently discussed making soft set honey. There’s also been quite a bit of interest in recent posts on oxalic acid/Api-Bioxal and the relative costs of the various¬†Varroa¬†treatments. Disappointingly, my semi-rants on the need for more sustainable beekeeping practices – including training and controlling imports – particularly in relation to stopping pathogen imports (both the visible ones like small hive beetle and the invisible,¬†and untested, ones like new virus strains) have received¬†relatively little attention (though they do appear to be recommended course material for a Masters degree of some sort). Maybe next year …

The search terms make interesting reading though Google (by far and away the most frequent referrer accounting for 96% of direct searches) hides these for commercial reasons and I can’t be bothered checking Google Analytics. I hope the person who searched for a¬†“cow dummy board” found what they wanted but¬†suspect the visitor who searched for how to build your own collapsible bin 1.2m by 1.2m plans and designs”¬†was disappointed. There’s been some recent interest how to¬†“demaree nucs”¬†which is a combination of terms I’d not expected to see and can’t see a need for. Can you? If the spelling errors that appear in the visible search terms are representative then it’s fortunate that Google and Bing both use algorithms to take into account common typos, fat fingers and the spektackularly¬†poor spelling of many internet users.¬†I use Akismet for spam filtering of comments and it’s amazing the garbage it’s successfully prevented from appearing online … any number of¬†“free pianos”,¬†“genuine Louise Vuiton” (really?) bags and RayBan sunglasses. Most recently was a long and fascinating post (er, not) about “making your breath smell good”¬†in response to my overview of foundationless frames¬†(shurely shome mishtake?)¬†I’m grateful to those who negotiated the “are you human?” Captcha¬†tests¬†and posted a comment or two. Without using Captcha tests¬†I’d be swamped with more free pianos than I’d know what to do with …

Plans

I’ve managed to post a bit more than the once-per-week target I’d set myself (64 posts in total). I suspect this will be throttled back a little next year, though I have a range of new things (oxalic acid/Api-Bioxal treatment regimes, homemade label printing, DIY hive monitors¬†etc.) that I’d like to cover. I’ve tended not to¬†write purely¬†topical posts¬†(“My hives this week”, which sounds more like something you’d find in the comments pages of NHS Choices)¬†– there are much better writers out there already doing this* – instead concentrating on more practical aspects of beekeeping. It’s sometimes difficult to achieve a balance between the ‘flow’ of the beekeeping year – the inactivity of the winter months¬†vs. the never-quite-keeping-up activity in May and June – and writing practical and topical¬†posts, after all, most practical beekeeping happens in that 2-3 months between the OSR starting and the end of the swarming season.¬†I’ve already¬†had some interest in discussing¬†the bee shed (and will try and respond to other requests) and want to expand some aspects of queen rearing as I get more experience of different approaches. In particular I’m interested in looking at practical solutions – like vertical splits – for small scale beekeepers who don’t want to graft but do want to improve their stocks. Having moved to Scotland I also now have potential access to some very scenic apiary sites (at least used by friends, even if my own are relatively dull and boring) and I’m hoping to combine visits to these with my photography interests.

It’s never too late to join the 21st Century …

I’ve finally got round to including a widget (right) to mirror¬†my Twitter account @The_Apiarist. This was created way back¬†in January 2014 but got forgotten and was subsequently suspended by Twitter … presumably due to inactivity. More topical things might end up there (if I remember), leaving the more practical stuff for these pages …

Mid-April 2015 queen … I hope to see her again in about 4 months

As the year draws to a close I hope that in 2016 your mite numbers are low, your colonies docile, your queens visible and your supers heavy.

2015 in retrospect

The winter solstice seems like a good time to look back over the 2015 beekeeping¬†year. With the day length about to start increasing, what went right and what went wrong? Back in March I wrote that my¬†plans for the year were different from the usual OSR – swarming – queen rearing – summer flow – harvest –¬†Varroa treatment – feed-’em-up and forget ’em routine¬†as I was moving to Scotland in the middle of the season. Some of these things happened, though perhaps less than in a usual year.

Mid-season memories

Mid-season memories …

Spring – better late than never

Cloak board ...

Cloake board …

The OSR yielded poorly as the spring was cold and late. I didn’t even look inside a colony until mid-April. Colonies were only getting strong as the OSR flowers went over meaning that most of it was missed. The weather was unseasonably cold, with mid-May being 2-3¬ļC cooler than average. Queen rearing started in the third week of May and although grafting went well, queen mating was really hit and miss, with low temperatures and lots of rain lasting through May and June. On a more positive note, I used a Cloake board for the first time and was pleased with the results (I’ll write about this sometime in 2016 after using it a bit more). I didn’t use any mini-nucs this year as I didn’t want the hassle of dealing with them mid-season when moving North. Instead, I did all of my queen mating in 2-5 frame nucs, often produced¬†as circle splits from the cell-raising colonies. This worked well … and considering the lousy weather was probably a lot less effort than using mini-nucs which would have required constant attention and lots of feeding. Using poly-nucs I could prime them with a frame of brood and a frame of stores and adhering bees, dummy them down and leave 3 frames of foundation (or wherever possible, drawn comb) ready to be used on the other side of the dummy board. Once the queen was mated the colony would build up well and if – as often happened this season – the queen failed to get mated or was lost (drowned?) during mating flights it was easy to unite the queenless unit with a queenright one, so not wasting any resources.

Go forth and multiply

Split board

Split board …

Beginners often find the coordination of colonies for queen rearing, and the apparent difficulty of grafting¬†(it isn’t), a daunting prospect. When I’ve been involved in teaching queen rearing it’s clear that the relatively small scale approach I use (queenright cell raiser, grafting and – usually – mini-nucs) is often still¬†too involved for the very small numbers of queens most¬†beekeepers with just a couple of hives want. It was therefore interesting to raise a few queens using vertical splits, simply by dividing a strong colony vertically and letting the bees do all the work of selecting the best larvae, raising the queen and getting her mated. It has the advantage of needing almost no additional equipment and only requires a single manipulation of the hive (and even that can probably be simplified). Having documented the process this season I’ve got a few additional things I’d like to try in 2016 to make it even easier and to allow better stock selection. After that it will be incorporated into queen rearing talks and training.

Changes in Varroa treatment

The big change in¬†Varroa treatment in the UK was the licensing of Api-Bioxal. Whether or not you consider the 50-fold or more cost of VMD-approved oxalic acid (OA) over the generic powder is justified is really a separate issue. Oxalic acid is an effective miticide and, if administered appropriately, is very well tolerated by the colony. Despite the eyewatering markup, Api-Bioxal is significantly less expensive than all other approved miticides. For the small scale beekeeper it’s probably only 20% the cost of the – often ineffective – Apistan, or either Apiguard or MAQS. Under certain circumstances – resistant mites, low temperatures or the potential for queen loss – there are compelling reasons why OA is preferable to these treatments. If we hadn’t been using OA for years the online forums would be full of beekeepers praising the aggressive pricing strategy of Chemicals Liaf s.p.a¬†in undercutting the competition. Of course, if we hadn’t been using generic OA for years Api-Bioxal would probably be priced similarly to Apiguard ūüôĀ

Sublimox in use

Sublimox in use …

I’ve used OA sublimation throughout 2015 and been extremely impressed with how effective it has been. Mite drops in colonies treated early in the season remained low, but increased significantly in adjacent colonies that were not treated. I treated all swarms caught or attracted to bait hives. Some were casts and there were no problems with the queen getting out and mated (though the numbers of these were small, so statistically irrelevant). Late season treatment of colonies with brood also seems to have worked well. Mite drops were¬†low to non-existent in most¬†colonies being monitored through late autumn.¬†Colonies get mildly¬†agitated during treatment with a few bees flying about under the perspex crownboard¬†(you can see a couple in the image above … this was a busy colony) and a few more rapidly exiting the hive after the entrance block is removed. But that’s it. The colony settles within a very short time. I’ve seen no loss of brood, no obvious interruption of laying by the queen and no long-term detrimental effects. Sublimation or vaporisation of OA can – with the correct equipment – be achieved without opening the hive. I expect to use this approach almost exclusively in the future.

Moving bees

Moving colonies from the Midlands to Fife was very straightforward. Insect netting was an inexpensive alternative to building large numbers of travel screens. It’s the same stuff as Thorne’s sell for harvesting propolis so I’ve got enough now to go into large scale propolis production ūüėČ The colonies all settled in their temporary apiaries well and I even managed a few supers of honey during the latter part of the season.

Small hive beetle reappeared in Southern Italy shortly after the honey harvest was completed there. Che sorpresa.¬†This was disappointing but not unexpected (and actually predicted by some epidemiologists). As I write these notes the beetle had been found in 29¬†Calabrian apiaries between mid-september and early December. It’s notable that there’s now a¬†defeatist attitude by some contributors to the online forums (when not¬†if the beetle arrives here) and – since not everyone are what they seem on the interweb – there are some playing down the likely impact of the beetles’ arrival (and hence the demand to ban imports) because they have a vested interest in selling early season queens or nucs, either shipped in or headed by imported queens.¬†I don’t think there’s any sensible disagreement that we would be better off – from a beekeeping perspective – without the beetle, it’s just that banning imports of bees to the UK (admittedly only a partial solution) is likely to cause problems for many beekeepers, not just those with direct commercial interests. I remain convinced that, with suitable training and a little effort,¬†UK beekeeping could be far¬†less dependent on imports … and so less at risk from the pathogens, like small hive beetle. Or of course a host of un-tested for viruses, that are imported with them.

And on a brighter note …

Bee shed ...

Bee shed …

The new development in the latter part of the year was the setting up of a bee shed to house a few colonies for research. This is now more or less completed and the bees installed. It will be interesting to see how the colonies come through the winter and build up in¬†spring. The apiary has colonies headed by sister queens both in and outside the bee shed so I’ll be able to make some very unscientific comparisons of performance. The only problem I’ve so far encountered with the shed was during the winter mite treatment by oxalic acid vaporisation. In the open apiary the small amount of vapour that escapes the sealed hive drifts away on the breeze. In the shed it builds up into a dense acidic hazy smoke that forced me to make a rapid exit. I was wearing all-encompassing goggles and a safety mask so suffered no ill effects but I’ll need an alternative strategy for the future.

Due to work commitments, house, office and lab moves, things were a lot quieter on the DIY front this year. The Correx¬†roofs have been excellent –¬†the oldest were built over a year ago and are looking as good (or as bad, depending on your viewpoint) as they did then. They’ve¬†doubled up as trays to carry dripping supers back from the apiary and I’ll be making more to cover stacks of stored equipment in the future. Correx offcuts were pressed into service as floors on bait hives, all of which were successful.

With well-fed colonies, low mite counts, secure apiaries and lots of plans for 2016 it’s time to make another batch of honey fudge, to nervously¬†(it’s got hints of an industrial cleaning solution) try a glass of mead and to finish labelling jarred honey for friends and family.

Happy Christmas

Foundationless frames reviewed

New comb ...

New comb …

One of the big successes of this season has been the use of¬†foundationless frames. These have reduced my¬†use of foundation by over 75%, leading to a significant accumulation of unused packets which were ordered before the¬†season started (as an aside, if stored flat in a cool place foundation should be OK for years, simply needing a quick blast with a hairdryer to remove the pale bloom that appears).¬†Aside from the economic benefits, I’m convinced that the bees draw comb on foundationless frames at least as fast as they do on frames with foundation. In some cases, given the choice, the queen also starts laying in the foundationless comb earlier. Finally, they are an ideal way to prepare a bait hive, providing the volume the scout bees are seeking coupled with the ‘order’ that will ensure that any swarm will build comb where you want it.

Foundationless frames

Super frames …

Preparing new¬†foundationless frames takes a litte more effort – you need to drill the sidebars and ‘wire’ them with nylon monofilament fishing line before adding a narrow starter strip. At least, that’s what I do. In my view this effort is more than offset by the benefits they provide. Framebuilding is made almost pleasurable by using a nail gun … look out for special offers on these from Amazon where a suitable model (Tacwise EL191) was recently reduced to under ¬£40.

Foundationless frames also work well in supers. I prepared a few boxes of these this season and extracted them using a radial extractor. With a couple of exceptions the frames all survived. The only two that collapsed were either partially drawn or incompletely filled. I treated the foundationless frames as roughly (or carefully) as those with foundation during extraction РI uncap with a hot air gun and wind them up to full speed as quickly as practical.

That's blown it

That’s blown it …

 

The only real problem I had with foundationless frames in supers was getting unwanted brace comb in boxes where the frames were not vertically aligned with the box below. For example, an eleven frame brood box topped with an undrawn 9 or 10 frame foundationless super sometimes resulted in the bees trying to build brace comb between the frames. This problem was partially, though not completely, solved by mixing foundationless frames with a few frames containing full sheets of foundation. Next year I will get the comb drawn in a super filled with foundationless frames, and then remove a couple and space them further apart.

Brace comb

Brace comb …

Other than the infrequent building of brace comb, which can usually be avoided by careful frame spacing, I’ve only had two issues with foundationless frames that might be considered problems.

The first is the bees chewing through the monofilament supporting ‘wires’. I’ve been using 15 kg breaking strain cheapo mono picked up from eBay. If the frame isn’t drawn evenly (perhaps because the hive isn’t perfectly level) the exposed mono on one side of a frame is targeted by workers and sometimes¬†nibbled through. In a frame with three transverse strands (i.e.¬†a deep, or brood frame)¬†this is usually the one closest to the bottom bar. This isn’t a major issue – it leaves a trailing strand which needs to be snipped off but the majority of the frame is usually drawn sufficiently well that it’s robust enough for the usual stresses and strains of inspections. In over 100 foundationless brood frames used this year, none have been unusable after the mono has been chewed through (which only happened on half a dozen). I’ve bought a big spool of 30 kg monofilament to use next year. At about 1p per metre it’s good value but may be a little less easy to work with.

Foundationless brood frame ...

Foundationless brood frame …

The second ‘problem’ is minor and depends upon your chosen method of swarm control. Colonies often draw out significantly more drone comb in foundationless frames than they do on standard foundation. It’s not unusual to have big slabs of drone comb on one or more of the outer frames of the brood nest. As a consequence, these colonies have lots more drones present throughout the season. Interestingly, I’ve not had¬†increased problems with Varroa¬†and deformed wing virus in these colonies. I generally use the Demaree method of swarm control, shifting the original brood box containing all the sealed brood above the queen excluder for a three week period.

Drone graveyard ...

Drone graveyard …

Consequently, drones emerging in the upper box cannot get out of the hive. If they are not periodically released – for example, during inspections, or by lifting the roof and crown board every few days – they sacrifice themselves struggling to get through the excluder. The standard inspection interval can uncover hundreds of dead and dying drones wedged half way throught the excluder. This is unpleasant, both for the beekeeper and the drones. Next year I’ll experiment with adding an upper entrance to allow the drones to escape – either by proving a thin shim of softwood underneath three sides of the upper box, or by providing a temporary hole through the side of the box (closed with a cork when not needed).

Finally, using a steam wax extractor on foundationless frames destroys much of the tension in the monofilament. They might still be usable – I’ve not tried – but it’s an easy job to replace it.

 

Saf Natura Extractor

Saf Natura Ritmo

Saf Natura Ritmo

This is a review of a 9 frame radial motorised Saf Natura Ritmo extractor, prompted by a recent discussion on the SBAi forum and the absence of many other reviews when I was researching the purchase. I hope it’s useful to others thinking of purchasing a machine.

Extractors are probably the single most expensive¬†item purchased by the majority of beekeepers. Actually, that should have started “an extractor” because a well-chosen machine that suits your beekeeping should last a very long time.¬†Try before you buy ‚Ķ borrow one from another beekeeper or, if your association owns one or more, book or hire one for a weekend to see how it suits your beekeeping needs. If your association is reasonably large it’s likely that demand will be high as the OSR finishes – honey must be extracted promptly or it will crystallise in the comb. Be prepared. Book the machine in good time and keep the removed supers warm to make extraction easier.

You may not need to buy an extractor at all. Many don’t. If you’re¬†flexible about when you can extract, or well organised, you might be able to share with friends or use the association machine(s). I’m certainly not well organised and often have to fit extraction around inflexible work commitments ‚Ķ

Extractor size – 3, 4, 9, 18 frame?

This is my second machine ‚Ķ the first being a 4-frame Lega manual tangential model which, although excellent quality, was simply too small for the number of colonies (~10) I now have. Small or large extractors (in terms of number of frames) take about the same time to extract the honey per spin, so buy a larger model if you want to spend less time extracting. This has been extensively discussed elsewhere. Since I extract twice per year (OSR and late summer) from about 18-24 supers (~200+ frames each time) and don’t intend to scale up I’ve decided a 9 frame extractor will suit me for the foreseeable future.¬†Famous last words.

Manual (hand cranked) or motorised?

Charles Atlas

Charles Atlas …

Motorised. End of discussion. Seriously. Unless you’re built like Charles Atlas, or want to be, I would strongly¬†recommend a motorised extractor if you’re considering a 9 frame or larger model. My manual tangential model was hard work after a couple of dozen frames. 200 would have been purgatory. Remember that if you’re handling 20 or so supers you will already be moving about 1000 lb.¬†of boxes around, before you start extracting, often in a warm room. For the model I discuss below the price differential between the manual and motorised version is about ¬£280. I think this is a good investment. You can often retro-fit motors to manual models, but I have no experience of this.

Why a Saf Natura extractor?

After outgrowing my manual four frame tangential extractor I’d borrowed a polythene-barreled radial 9 frame motorised Thorne’s extractor from our association. I was convinced about the capacity¬†and the motor but disappointed about the signs of¬†wear¬†on the polythene barrel. The machine had been used pretty hard by the association and would have become increasingly difficult to properly clean, so I wanted a stainless steel machine. All the standard suppliers sell these, at prices – for a 9 frame radial model – ranging from about ¬£600 to ¬£1600. The Thorne’s polythene-barreled model has a list price of approaching ¬£800. I looked carefully Abelo extractors on show at the Yorkshire Beekeepers Association¬†Spring meeting. Abelo¬†sell 8 frame tangential and 12 frame radial models, but¬†there were some rough edges on the stainless steel barrel of the model I inspected which put me off. I finally purchased a Saf Natura Ritmo extractor from Bee Equipped in Derbyshire. It was close enough to collect, so I wasn’t committed to purchasing until I’d checked the quality.

Ritmo motorised radial extractor

Manual motor

Manual motor …

The Saf Natura website provides details of this model. It is 52.5 cm in diameter and Рonce the bent angle coated steel legs are assembled and attached Рstands 102 cm high at the top of the closed lid. The motor extends the height a further 12 cm. Note that the model illustrated on the Bee Equipped and the Saf Natura websites both show what is variously termed a Saf Natura motor, or РI think Рa digital motor. These have an additional control box on the side, presumably controlling time of spin etc. Bee Equipped only sell this extractor model with a more basic manually controlled motor as shown in the images here. I presume this helps keeps the price down to a very attractive £620.

Resin cage

Resin cage …

The other clear cost-saving is the cage for the frames. In this model the top and bottom¬†sections are¬†moulded out of some sort of plastic or resin, rather than being constructed from stainless steel. The top and bottom sections are joined by stainless steel rods. The honey gate is also plastic. Half of the perspex (?) lid hinges up to add and remove frames for extraction, in doing so the motor safety cut-out (red and black in the image on the right) is engaged. The overall quality, rigidity and finish of the stainless steel is excellent. It looks and feels like a solid, well made, machine that should last a long time. I use Nationals and the extractor¬†I purchased was set up for this frame size. By using longer stainless steel rods holding the resin cages apart it is possible to use Langstroth frames in the same model. I also purchased three mesh frames for tangential extraction from brood frames (deeps). Unfortunately these are only supplied in Langstroth dimensions so will need some minor butchering before being suitable for National frames (I’ll describe this later if I ever get round to it ‚Ķ the tangential meshes were only ¬£25 for three and I didn’t want to have to pay postage at a later date).

In use …

It works well. The motor makes the expected whining noise as it speeds up or slows down. It sounds strained but I’ve heard exactly the same thing with other extractors and you soon get used to it. Full speed is amply fast enough to clear filled supers, even of viscous OSR honey. There’s nothing to stop you opening the lid or slamming the machine into reverse when it’s going full speed ahead ‚Ķ other than common sense and a small adhesive label stuck on the lid. I’ve not tried and I suggest you don’t either. As with all extractors it wobbles with an uneven load. I’m going to investigate castors or foam blocks under the legs. However, if the wobble is bad enough it’s worth rearranging the frames to sort the problem, rather than simply hanging on for dear life as it dances around the room. The worst wobble I’ve experienced, which got progressively worse as the length of spin increased, was due to my forgetting¬†to uncap one side of one frame ‚Ķ D’oh! Crystallised OSR honey in part of a frame often causes problems for similar reasons.

I run the machine with the honey gate open, directly filtering the honey through coarse and fine stainless steel filters above a 30 lb. honey bucket. As long as you keep a careful eye on the level of honey in the bucket this method works well. A contributor to the SBAi discussion commented on the relatively short distance between the bottom of the barrel and the cage, causing the long frame lugs on National supers to foul the accumulated honey. This is avoided by leaving the gate open.

I’ve only had the machine for a season so cannot comment on longevity, spares¬†etc. Dot at Bee Equipped told me they’ve been selling this model for at least a decade with no significant problems, other than some models damaged in transit. Redesigned or stronger boxes appear to have sorted this problem out.

In conclusion … highly recommended.

Note that many suppliers aggressively discount extractors in the spring shows (BeeTradex or the BBKA convention) and that the very worst time to buy an extractor is at the end of the summer ūüėČ

Full speed ahead …

Everynuc poly nuc

Everynuc

Everynuc …

Thorne’s have introduced two new poly nuc hives recently – one called the¬†Polynuc (~¬£27) and the other the Everynuc (~¬£47). Both are available in British National dimensions. I’ve not seen the Polynuc but consider the walls, at 22mm, to be a little on the thin side for overwintering colonies (perhaps about the same as¬†the Paynes poly nucs). However, I have recently taken delivery of half a dozen Everynuc poly nucs with the intention of expanding my stock, by splitting production colonies (after the honey harvest) and using mid/late season-reared queens to take them through the winter. Here are my first impressions.

Everynuc floor

Everynuc floor

The Everynuc is an interesting design. It’s available in a range of different sizes; Langstroth, National, Smith, Commercial, 14×12, Dadant¬†etc. All have a rectangular, preformed (i.e. no assembly required) brood box with 40mm thick walls and neat metal runners at each end for frames. I suspect this box is the same size for all frame sizes. To accommodate smaller frames¬†e.g.¬† National in the Langstroth-sized box, they supply a slot-in feeder that takes 2.2 pints. The deeper frames¬†e.g. 14×12 and Commercials also include a 40mm or 60mm eke that presumably goes between¬†the brood box and the removable floor. The latter is sloping, with open mesh and has a removable tray for¬†Varroa monitoring. There is a clear plastic crownboard and a thick roof. The exterior of the box is commendably smooth, so much easier to paint than the Modern Beekeeping/Paradise Honey boxes).

Bee space

Bee space

Thorne’s claim the Everynuc is top bee space. Well, it is and it isn’t. In the National size, the top edge of the feeder sits 2-3 mm above the frame runner, meaning that the top bar slopes. To rectify this I’ve cut a couple of millimetres off the bottom of the feeder lugs, effectively lowering the feeder sufficiently to restore top bee space. While we’re on the subject of bee space, it’s definitely wrong at the end of the box without the feeder where I measure the gap at 1.5cm. This is poor and may reflect some sort of compromise to accommodate the different length lugs on National and other types of frames. For the moment I’ve not done anything about this, but if brace comb becomes an issue I intend to skin the inside end panel with some 8mm ply to restore the correct bee space.

Not 6 frames

Er, no …

The Everynuc is designed for 5 frames and a dummy board. With brand new frames you can just about cram 6 frames in, but as soon as the Hoffman spacers get a bit of propolis on them it’ll definitely be a 5 frame box. With good thick walls and a solid roof this is a good size to overwinter.

FIve frame poly nuc

FIve frame poly nuc …

Everynuc feeder

Everynuc feeder …

In addition to lowering the feeder I’m looking at ways to add a metal or plastic runner to the inside edge of the feeder, fitted just proud of the cut ply, to make frame manipulations easier. I’ve also added a thin piece of stripwood across the top of the feeder to stop the frames sliding backwards and forwards when the boxes are being moved. There is a small wooden spacer on the bottom edge of the feeder, but this additional cross brace should add a bit more security and prevent bees getting crushed. On the subject of moving colonies, I routinely make up 2-3 frame nucs for queen mating and then transport them from one apiary to another. Rather than letting the frames slide about side to side I’ve cut small blocks of dense foam to wedge them tightly in place for travel. An additional block of foam will be required for the entrance, which is wide and, with the short ‘landing board’, an awkward shape to block with mesh held in place with drawing pins (my favoured solution to transporting nucs).

Everynuc entrance

Open wide …

First impressions of these nucs are reasonably positive. The beespace might be a problem, the frame feeder really shouldn’t need lowering¬†and the entrance is likely to require some sort of reducing block to prevent robbing. However, the poly is dense and well moulded, with no real nooks and crannies to harbour pathogens. Cleaning should be straightforward. The boxes will stack if it is necessary to unite colonies.

Finally, I wonder how many beekeepers noticed the name of the manufacturer of the clear plastic crown board …

Foundationless frames

Foundationless frames

Putting¬†frames together is one of those tasks that should be undertaken in the dark days of winter when it can be done at a leisurely pace. There’s a certain satisfaction from the mindless repetition of the process, whether for standard frames with foundation or¬†foundationless frames (with the latter requiring a bit more effort due to the drilling and ‘wiring’ necessary). However, it’s cold in the winter and there’s certainly no satisfaction from bashing the end of your thumb with the hammer. Your fingers are semi-numb with cold, barely able to grip the gimp pin, which is too small to hold in a gloved hand. Self-harm is almost inevitable.

Supers

Supers …

Of course, in the summer, if you need more frames you need them¬†yesterday. There’s nothing leisurely about it. There’s a flow on, the supers are filling faster than you can keep up,¬†the bait hive has been occupied by a swarm and you need to set another up or you urgently need a dozen new frames so you can move the nucs to full brood boxes. With nucs being sold, swarm control and 8-10 honey producing colonies I get through a¬†lot of new frames each season. I’ve not counted, but do know I’ve used nearly a full 100 metre spool of 15kg monofilament making foundationless brood frames alone, each using about a metre of nylon.

Tacwise nail gun

Tacwise nail gun …

I needed six new supers with frames for the weekend inspection. There’s a good flow on, possibly lime, and I’ve more or less run out of boxes. Constructing the supers from flat-packed seconds bought in the winter sales was¬†a trivial job. Knocking together the ~60 frames I needed to populate them also turned out to be quick and easy as I’d generously been given¬†a Tacwise EL 191 Pro nail gun. This is a light duty electric model, using 18g nails from 10-35mm or type 91 staples from 15-30mm. This was the first time I’d used it for building frames. What a revelation!

Nailed

Nailed …

The usual incessant tap, tap, tap (or, at best, tap, tap) for each of the 8 gimp pins in a frame was replaced with a satisfying ‘chunk’ as the nail gun drove the galvanised 20mm pin flush with the surface. It didn’t take long to get the positioning accurate and adding the six pins (four on the top bar and two holding one of the bottom bars in place) took less than 15 seconds. Most of the frames ended up with thin unwired foundation for cut comb so I fitted the second bottom bar with standard gimp pins. This is necessary as they are easy to remove (and I’ll need to add fresh foundation next season), whereas the nails driven by the nail gun are almost impossible to shift once they’re driven in flush.

Since the nail gun is essentially single handed there’s no chance (well, almost no chance) of injuring my thumb. I might even be able to use it with gloves on in the winter.

I now need to order some 18g 35mm nails – the largest this model takes – for building boxes ūüôā
