Taking my lunch break from extracting so thought i would answer some of the points raised.
1 What is the practical difference, if the frames are the same size?
You need to make it deeper to accommodate brood as well as super i.e. when you push down you need the depth.
2 How did you attach the uncapper to the support frame? I can see the frame is clamped to the base unit, but how did you attach the uncapper to the frame?
When it attaches to the plastic box it uses two Number 6 bolts, i drilled 6mm holes through the wood and just bolted it in position.
We were both disappointed with the amount of honey left in the frames after extracting ( I would estimate about 10%)
Not sure i agree on this statement i had a few frames with some honey left in, not sure any more than normal. A friend is going to do another test but to be honest as the frames are going back to the bees if they get a little extra honey not worried, more for winter stores. As i take off all the supers if they get a small extra amount extra back fine. But think it is if at all or marginal.
but what disappointed me most was the amount of damage done to the comb especially if you put it through a second time to try to overcome the problem with honey left in the comb.
I did a test on this and again just now with Roger. We took a frame and cut half of it clear with a knife flat to the frame and half left then put through the machine then extracted. Now the half which just went through the machine sure messed up with the blades but it goes no deeper or not much than you would with a knife so even if the bees clean that all up no loss. It will though be interesting when i put them back on the hive if the bees discard the wax or use it to clean up, will put boards on to check.
small fragments of wax caused by the damage soon clogged our course filters
Again i run a course and fine filter settling tank after 20 boxes i cleaned off the course filter no worse than normal and not a long job just scraped it onto heated pratly tray.
it’s the fact that the uncapper doesn’t open some cells around the perimeter and low areas.
Agree on this, found i just did those with a fork quickly, nothing is ever perfect but quicker than by hand for me.
If reducing your wax processing is an important criteria I would suggest buying a hot air gun as it causes no cappings and is significantly cheaper than the uncapper at £299.
My preferred method, but when i compare the two i get more honey out by far using the roller.
Had a visitor today to see it for himself
