Cutting acrylic
Hello all,
I am making a couple of parts from cast acrylic, with a "large" run[*] probably going to happen in the near future. Rough cutting was more trouble than I remember, probably because of my cheap Craftsman buzz saw. The main problem with the cutting was that the plastic melted and partially re-attached. Some repeat passes with some cooling breaks removed enough of the excess that it finally separated. Am I correct to think that a bandsaw will eject the material and (largely?) avoid the problem? Is there a preferred speed and tpi to try on the buzz saw? Thanks! Bill [*] that means more than five sets of them |
