Hi,
I was looking at my home made grape press and I can see no reason it could not be used for honey extracting for top bar users.

Have a look at any brewing supplies websites to see what I mean.I find them in thier winemaking equipment section,grape crushers,presses.The crusher that sits on top has cutters to mash up the fruit/combs,the press then squeezes out the juice/honey.You could probaly get by with just the press,mash up the combs in a bucket then tip into the press.,we do that with our grapes.You should be able to run a few combs through at a time

There are stainless steel models which would make them much more food grade than my version.

Any one using one or has thoughts on them?
Thank You
