What size does the lower anvil need to be on one? I've seen where some used a large carriage bolt but didn't say how large. Would a 1 7/8 trailer ball work or is that to big? I'm building one and that is the only thing I'm not sure about. It'll be a smaller one you can put in a vise.
The lower anvil gets changed to the same radius as the panel you are planishing just like an english wheel. Sent from my SM-G950W using The H.A.M.B. mobile app
