2018 Beverley Beekeepers Auction

Conflicting with Whitby Goth Weekend this year was Beverley Beekeepers' Annual Auction. No doubt this caused sleepless nights for many beekeepers in the East Riding as they deliberated whether to dust off the New Rocks and head for the coast or empty the back of the estate and head to Woodmansey in search of bees and woodware.

Jars, buckets, woodware, shiny things, fondant..
The Auction started at 11am on the Sunday morning, I rocked up at half past. The hall was noticeably fuller than previous years. As expected alongside the usual hives and Supers there was a huge range of equipment on offer, ranging from buckets of formic acid pads and sugar to microscopes and a cuddly toy.

Bucket of 10 Formic Acid Pads, went for a pound
Hard to imagine an apiary without one of these
Actually the bucket of Formic Acid went for £1, the cuddly Winnie the Pooh dressed as a bee and accompanied with a few large flowers went for £6. The acid is for treating Varroa, the Pooh bee and flowers are props for educating children about pollinators. I'm not sure what the Brunel SP20 Microscope went for but there was also a binocular microscope amongst the lots too.

Beekeeping isn't all banging nails and burning stuff
As usual there were a few shiny motorised extractors standing out against the boxes and wood. I bid on a couple of those but was unsuccessful so if I get a honey crop this year I'll be extracting with my trusty two frame manual extractor.

Motorised Extractor, it's gone to a new home.

One thing that caught my eye was the Honey Twin-Spin. A two frame electric extractor which appears to have been designed by some guy was hugely into fifties sci-fi and probably saw flying saucers in his sleep. It's a two frame radial extractor but unlike every other extractor I've ever seen holds the frames almost horizontal. It's made by Brinsea Products who are still around but nowadays focus on poultry rearing.A quick Google finds the extractor  mentioned in an old Kent Beekeepers Association Newsletter. The writer comments on how efficiently it extracted as well as being particularly easy to clean too. It didn't generate much interest and there was only myself and another chap bidding on it, he got it for £16. It's an odd looking and bulky thing but £16 for a motorised extractor is quite a steal.

Flash Gordon's Honey Extractor
In previous years there's usually been a lot of Nucs on sale, probably because most beekeepers get free ones with their first colonies and later it's probably one of the first things they build for themselves. I've made four myself, and still have a couple of others knocking about. This year the Nuc contingent was limited to a group of five brightly coloured wooden Nucs and a couple of Poly Nucs with built in feeders. Perhaps people are keeping their spare Nucs for making splits later in the year.

How come that bear is in so many photos? :-o
A couple of Poly Nucs
Of course the main draw was the bees. Winter losses over 2017/2018 have been seriously high across the UK, Europe, USA and Canada, figures I've heard bandied about have been up to 90% for some. This means there's going to be a lot of beekeepers looking to replace stocks and conversely far less bees available for sale.

Bees for sale

There were 12 colonies for sale this year. 8 of them were 5 frame Poly Nucs with July 2017 Queens ready to be hived.They went for £240-250 each. From the descriptions I think these nucs actually contained bigger colonies than my surviving hives at the moment. I've long since realised that trying to predict bidding is impossible so I wasn't hugely surprised when two full sized colonies in National Brood boxes complete with floor and roofs containing 6 and 7 frames of brood respectively went for £230 and £240 each. That's less than the smaller colonies in the Nucs and basically includes a usable hive. A Poly National hive with 6 frames of brood and four spare empty Supers also went for £240 and the last colony another Poly National but with a half filled Super and 3 spare empty Supers went for £250. The last colony I bought at a previous auction was £150 and one year in York I saw 2 Nucs going for £50 each, the prices this year probably reflected just how heavy the recent Winter losses have been.

These bees couldn't wait to get to work

It was really cold outside but a lot of people braved it for the bee sales. Before proceedings went back inside a gazebo and a 6x4' trailer also went under the hammer. Whilst probably not the first thing most people think of a Gazebo would've been really useful for me over Winter when I was working on hive floors in the snow. I've also had the weather change after painting hive parts and hd rain completely wash off the wet paint in the past.

The right place for a gazebo or trailer


Back in the warmth the hall was noticeably emptier. Probably as a lot of people had come specifically to buy bees -have I mentioned those Winter losses?.. I guess a few will also be going to the York Beekeepers' Association Auction on May 12th. After the bees have sold and the crowd has thinned a little is a good time for bagging a few bargains. A few people got honey buckets with lids at four for a pound, mesh floors went for a pound each too. I picked up a solid wooden floor for £7, that'll be going under a spare hive at the apiary in case a passing swarm feels like moving in. They're also handy to have around when you're moving full Supers and extracting.

Perfect for Asda
There's usually something unusual at these auctions and this time the oddest thing was probably a wooden box on wheels. Inside it on one side there were a couple of net curtain wires attached to the frame to hold things in place. The were also six swarm boxes on offer but they didn't meet their reserve.The swarm boxes are lightweight boxes the size of a 5 frame nuc with straps, a close fitting sliding lid and mesh areas for ventilation. When you're moving bees it's important to keep them cool. Being based in a city I've not had to travel far to collect a swarm yet so I just bring a Nuc when I go to collect them. If I was travelling further I'd probably think about one of these ventilated boxes.

Ratchet Straps, Uncapping Tray and Fondation

As the Auction progressed I picked up a box of beekeeping books and a medium size bee suit for a fiver, quite a few people are interested in seeing my bees so I got that for visitors. There was some steelware in the form of a couple of uncapping trays, that always gets interest. A large honey warming cabinet went for £30, useful things, this one looked like it could take a couple of buckets at a time. At the moment I have some jars of liquid honey that's granulated so they'll need a spell in my warming cabinet before they sell.

Honey Warming Cabinet
Something which didn't sell but would save someone a lot of labour was a motorised Honey Creamer. From the outside it looked a lot like an extractor but inside instead of a cage for frames there was a little propeller near the tank floor. You load it up with liquid honey, add some existing creamed honey from th previous year, turn it on then go do something else whilst it mixes. At the moment I use a strirring device that attaches to a drill and cream the honey in 9 litre buckets. It's still fairly hard work and takes a long time mix it consistently.

Honey Creamer
Stainless Steel Settling Tank with Filters
The second to last lot was a heavy little stack of glass rectangles. It turned out they were glass quits, basically a glass Crown Board. Each was in two halves and each half made from two panes of glass joined together. They allow a beekeeper to see where the bees are in the hive without fully opening the colony. I'm not sure why these are in halves but it might be to do with weight and strength, it'll also mean not having to open up the full hive at once which should reduce flying bees. Nobody was interested in them although polycarbonate quilts had had some interest earlier in the day, so I them up for £2, making them £1 each. I'll see how they are to use -if I like them I may be popping up the road to Jack's Glass for some more. The last item was a very tall stainless steel Settling Tank with built in filters. I was interested in that but so was everybody else so it was soon bid out of my intended budget.

Section Racks
Towards the end I managed to pick up a pair of Section Racks with metal spacers. There was the usual boxes of jars and foundation. I didn't need any foundation this year having traded in a load of wax for foundation last year. I did pick up 72 1/2lb jars with lids for £12 and 72 1lb jars with lids for 17. Not the most interesting purchases of the year but jars are quite an overhead for beekeepers so any chance to save on them is welcome.
Solid hive floor and a little reading material
 When I got home with my little haul the first thing to do was scorch everything - well okay not the books, that'd've gone pretty badly, but the floor, section racks, their metal spacers and even the smoker, whilst it doesn't come into contact with bees it comes into contact with gloves that probably have.

Snelgrove Board, front and back views
I had bid on a couple of Snellgrove Boards but didn't win, however the chap from Green Man Honey who had won them was kind enough to sell me one after the auction. They're made from two thicknesses of ply with cutaways at the exits on one side, an unusual way to do it but will certainly make for a strong board. When I scorched it the glue holding the mesh liquefied so I scraped it off, burnt it off the mesh then stapled the mesh back in place.

This Smoker reminds me of The Klangers.
It was a fairly busy day, with three different auctioneers taking the gavel. The impact of the Winter losses on attendance was pretty obvious. As usual the auction is a handy place for beginners to quickly and cheaply stock up on kit. As well as the sales mentioned above National Hives assembled and painted, complete with two supers were going for £40-£50 each.

Floored

In response to last Winter's losses which were worse than all my previous years added together I've decided to switch from treating Varroa by trickling oxalic acid solution to vapourising it instead. The main difference for me is that whilst both treatments work best when there is no brood in the hive trickling can only be done once a season whereas the Oxalic Vapour treatment can be repeated. Last Winter was warm enough in November, December and the first half of January for the bees to continue raising brood, this delayed my application of Oxalic Acid solution and also reduced it's efficacy. If I was vapourising I'd've been able to apply it two three times a week apart. My regular open mesh floors would need sealing up to use a vapouriser  which would be a bit awkward so I decided to make new floors to better accommodate a vapouriser.

Rather than reinventing the wheel I looked at a few floor types and decided to make a version of the "Kewl Floor." Terrible name sounds like something from an 80's teen oriented music magazine, possibly it was invented by a chap with an unfortunate name - doubt it though. The Kewl floor is based on the Dartington Hive floor and similar to a Heather Floor.The entrance is a set back vertical 8-9mm wide slot which mice can't get through and the bees can better defend from wasps by having guards on both sides.

There's a few webpages with plans and descriptions of the Kewl Floor, my starting point was a post on The Apiarist's blog with lots of handy pictures and even a cutting list for National Hive size floors, I use Commercial Brood Boxes which are (meant to be) 5mm longer and wider than Nationals and based my floors on wood available from B&Q as, fairly typically, I decided to start work in the late evening and they were still open. As per usual I took a tape measure along as wood is sold using "nominal" measurements which seems to be wood yard speak for "we're shortchanging you."

I found the B&Q's nominal 47x75mm meant 46x72mm, their 22x75mm was 21x70mm and their 25x100mm was actually 21x96mm. So a difference of 1 to 5mm depending on which measurement you're looking at. Whipping out an Android Tablet and firing up the excellent Google Keep I knocked out a quick design based based on three different sizes of wood with a 465 x 465mm footprint. My plan was to make floors that I could treat using a Vapouriser from below the mesh floor.

Google Keep diagram - just add 22mm battens on top

To accommodate a vapouriser the rear wall of the floor which would be below the mesh needed a 14x90mm slot cutting into it. That meant a quick trip out to buy a chisel. I'm pretty sure with a bit more time and patience a semi decent carpenter or trained monkey could've made a nice uniform cut but I was working outside, it was cold dark and snowing so I just did it quickly and tidied up the face with a file.

14x90mm slots to accommodate vapouriser
I decided to build the floors using wood glue and screws. That may be a bit of overkill given the strength of modern wood glues but with a few supers and an artifical swarm on top the hives can be extremely heavy. Marking the outside surfaces with a rough map of where the pieces would go I drilled pilot holes for the screws.

You know the drill

I used a drill with a screwdriver bit and lubricated the screw threads with a little wood glue. Using such long screws turned out to be a complete pain the proverbial. I had problems with screws getting stuck part way in and the drill stripping the heads so I'd have to stop and use huge plumbing pliers to grab the head and slowly remove the things before trying again with a new screw.. eventually I switched to nails. I gather nails have a greater shear strength than screws although screws are better for holding pieces tightly together. Switching to nails with pilot holes and a little wood glue really sped things up.

Stripped screw head. Again.
Clamping the pieces to screw and nail together took a little creativity with the clamps, I gather corner clamps exist but I don't have any. What I ended up doing was attaching the rear piece first then the front pieces and finally clamping the middle vertical piece tight against a 9mm drill bit to get the correct gap size for the slot.  It took a little knocking with a hammer to get the middle piece of wood in place. There is a bit of wriggle room in the 8-9mm slot with really as it's intended to give room or the bees to pass back to back. The important thing is not to leave a gap over 9mm wide otherwise your hive becomes a Winter Mouse House.

9mm drill bit as a spacer

Snow! Fantastic...
With the main structure and the entrances complete the floors needed a mesh section over the main area. I had a couple of mesh squares knocking about from previous projects and ordered another ten from Simon the Beekeeper. Initially I took a mesh square and cut out an area slightly wider than the entrance slot and stapled it in place then put the 22mm battens forming the top edge over it. Cutting a slot in the mesh was a bit of hard work. I later cut a rectangles big enough to cover the hole but small enough to fit inside the battens and stapled them in. I used stainless steel staples to hold the mesh as I don't want condensation to rust them -that and I a load left from re roofing my chicken coop.

Two down, eight to go
I was initially measuring and cutting the battens to fit the floors but decided a faster and more accurate way was just to attach the whole batten butted against an off cut then cut the excess then repeat butted against the previous piece. This saved a lot of time, accommodated tolerances across the pieces and removed of wastage from measuring mistakes ..which I did manage a few of earlier - used them to fuel the chimnea I'd lit to supplement the three pocket warmers I was using as most if this was done across a few freezing February evenings.

Sliding Bottom Boards
The bottom boards were made from thin plywood I'd found someplace. I made thin wooden runners to go underneath the boards making a very close fit and attached a batten under the rear of each board to function as a handle underneath.. I actually only made three of these wooden sliding boards as I only had a little plywood and make the rest from correx. The correx ones are just to use as regular sliding bottom boards for checking varroa drop but the wooden boards should be able to support a hot vapouriser. I'm only going to be able to vapourise one hive at a time anyway so three wooden boards should be okay. You can buy correx sheets but its easy to find free as it's used for signs which often wind up in skips or just fly tipped.


One completed floor with fitted wooden bottom board
I made ten floors in total. I don't really intend to have ten full size colonies in the foreseeable future but it's handy to have a few spares around in case something unexpected happens. I also like to be able to swap out floors for fresh ones after winter to remove any dead bees and detritus and sterilise them.

Art Attack
I gave the finished floors a lick of shed and fence paint on the outer surfaces leaving the inside and pack of the entrance area unpainted. I used some badly mixed brown and black paint to give an uneven coloured finish making the floors look a little less tempting to others and making each one unique which I hope will make it easier for the bees to identify which entrance is their own hive and reduce drift.

10 Finished Floors
I'm quite pleased with the finished floors but it later occured to me they could be improved by having the lower part on the entrance sloping down instead of horizontal. It would mean making an angled cut along the back of the landing board so it fits flush to the back of the alcove and make drilling pilot holes a little tricky but would have two advatages. Firstly rain would run off and secondly anything the bees drop out of the entrance it such as dead brood, bees, wasps, bits of wax, newpaper from unites etc would fall away too.
