Heres my latest bit out of the workshop, It's now where near perfect, but its better than it was. It runs quite well, goes on the governor at about 30psi, andwill hold its speed up to just over 40psi, turn the compressor off, and it stops just over 10psi, would go a little lower if the belt to the governor, and the feed pump were removed. It uses a lot of air, my little compressor will barely keep up.
