soldering up the i2C multiplexer board for the latest hive...
QUOTE]
Busys busy busy (with my one hive!). Made up an acrylic/wood crownboard for easy peeking in winter. (Workshop thread, I know... And how the heck will I cut a feeder hole?).
The answer is, slowly with a tank cutter mounted in an electric drill ... go slowly or the heat generated will melt the acrylic and it will clog up the cutter. Save the piece you have cut out and glue a slightly larger square of perspex or plywood to it and you have a ready made lid to go over the feeder hole when you don't need to feed them. The bees will glue it in with propolis so there's no draughts.

Not the best quality in the world but I have a set and they work OK for the money.
Then, brainwave! Foundationless frames! As an experiment, one foundation in the middle then empty frames alternating with strips of one third of super foundation.
You really need to wire the frames horizontally if you are going foundationless as that holds the comb in place when you are inspecting, otherwise it can sag a bit under the weight. You only need about an inch of foundation as a starter strip - the bees will sort the rest out. All my frames are foundationless and they are fine - only mistake was mine when I built the hive I left 2" of space below the bottom bars and the mesh floor - so the bees extended my frames downwards and I now have 14 x 14 frames !!

Post #8818,
All their own work - you don't even need to altenate with full foundation, as long as the first frame gives them a guide they will be fine
To follow-up on the good Doctor's comment.
Its generally not a good idea to put a syrup feeder on a clear plastic coverboard. The weight causes it to flex and sag, which reduces the beespace, which causes the little dears to make a mess of the once-nice clear board.

My experience of making my own clear coverboards out of 6mm acrylic with a timber frame around the edge is that they haven't sagged with test weight of 2Kg on them - I was a bit worried but didn't want to have a greater thickness than 6mm.

This stuff is expensive though! Or I need a better source than Wickes. £16 got me enough 2mm for 2 crownboards and a wasp pane

, should I make some photo album?
No. Beautifully executed and interesting, definitely. Lovely, no.lovely pics,

T's use polycarbonate, rather than your acrylic.
Theirs do deflect enough with a 4-pint rapid feeder full of syrup (total almost 4kg?) to promote brace and prop. It was the brace and prop that made me notice the deflection ... And after you remove the feeder, they still add to the brace and prop that they had started ...
Hence I have clear boards with no holes.
And I have thick plywood boards (with a hole) as clearers and feeders. Neither of which should be on for very long.
/ And given the cost of the material, I've simply bought the clear ones from T's ...
I picked up my 6mm from ebay ... seller I found is not on there at present but there's a similar one here:
http://www.ebay.co.uk/itm/5MM-PERSP...t=LH_DefaultDomain_3&var=&hash=item41719a63bf
It's 5mm thick and a 400 x 400 sheet is £12.53 including delivery - by the time there's a frame around it you have a standard hive size ... better than the 2mm thick polycarb from Th's and £6 cheaper (without any delivery charge as well).
500 x 500 is £17.39 which is still cheaper than Th's and you could use the offcuts to glue round the edges as a frame and stiffener.
I'm sure if I looked a bit further into ebay there would be more ..
I do understand what ITMA is saying ... my thinking was that with a hole in the clear crown board (filled with the infil piece as I've made) it would be possible to see into the hive and add either fondant or later on, in spring, a rapid feeder without having to remove the crown board. Just use the hole which is a lot less disruptive than taking off the whole crown board which the bees will have propolised as well.
