ACE Converter anomaly, REDWOOD

Thanks Jerry,

I see what you mean. I had him press a piece of scrap against the end
side of the cut, but he still got a little splinter. Probably need to
CLAMP the scrap in with the work. Of course I hadn't thought of that
before I got him started. Never have that problem with metal!
