The cutter head has a 8 inch opening with a constant equal slope all the way around. I think I can cut lumber type stuff up to about 8 inches wide. With the smaller usual stuff I will be cutting I can feed it in toward the later end of the cut.
I was looking for a 12 inch cutter head but I could not find one. I used what I had.
Good wire, good shielding gas, a good welder, and new steel helps a lot.
This mornings progress. The anvil mounted, the work rest mounted, the splitter cut and a lot of bracing installed.
