I was gifted my version of this beast - Belsaw name plated in my case.....
If I am reading things correctly, it will take a 12" wide board by up to 6" thick.
Unfortunately, not molding knives, but the seller did say he had the other feed table and he thought the crank too (which would be really helpful because using a set of channel locks and turning the shaft 1/2 way at at time took forever to move it down to be able to clean the bed.
My gift included a few molding knives that I have never used - and likely never will. Happy to have these find a home where they would get used.
Interested? PM me. I'm in Raleigh.
