quite a mess, I assume?
Not really, you just need a propper setup. I really like the wooden frame/plastic foundation method. I'm currently exchanging all my frames to that.
But the key here ia to use propper foundation likr PF-100 or ACORN. The bad name about plastic foundation/frames in germany is caused by the Nordwabe, wich is really inferrior to these, cause of Bad construction. 0.5mm cell rims and flat bottoms are just not cutting it.
(And i hate wiring so bad)
Well, wax gets brittle when frozen. Should make the job a lot easier if they are frozen.
I know of a company in Oz wich is running fully on ceracell deep plastic frames, they constructed a conveyor, essentially 2 rails to guide the foundation long side and a bottom rail. Then have a chamber w?re two pressure washers are fixed and clean the foundation of the wax, while it is pushed through.
