I used my Ammco shaper for the first time yesterday. I had a steel bracket that needed thinning down. I found I could only take very light cuts and the finish wasn't that great. I think there is wear in the ram which was allowing the cutter to move vertically. I tightened the gib strips and that improved things. I'll try again today, see if I can get a better finish. It was great to get it going, so quiet and you don't have to watch though you tend to.
