Ive got a grizzly g0632 it came with a standard 12" tool rest with a 25mm post. I'm looking to add a shorter rest like possibly a 6",post but I cant find any that are 25mm posts? I have a left over nova modular post with a 4"rest but its a 1" post. would I be better off getting a whole new banjo assembly that is based on 1" post as they are easily available? What are your thoughts.
