[TheForge] Chop Saw Irritation

Mon Jan 28 22:10:00 2002

In my experience this is caused by the blade getting a glaze on it. If you 
bounce the blade a couple of times into the cut it will knock the glaze 
off. I know an old fabricator that uses a piece of scrap stock to bump 
against the edge of the blade to clean it up. I guess its acting like a 
belt sander that gets choked.

Note of caution - bump the EDGE of the blade  - not the side....
