Use a stone instead of a file. The plexi drill I have seen had a small bevel ground on the cutting edge at approx 45 degrees. This perhaps had a width of 1/32" on a 1/2 inch drill. Plexi can be cut cleanly and easily without a saw by first scoring along a line, then placing the scored sheet on top of a broom handle or dowel, and striking a sharp blow. This works best for smaller cuts. -- Jeff Mulligan (jbm@aurora.arc.nasa.gov) NASA/Ames Research Ctr., Mail Stop 239-3, Moffet Field CA, 94035 (415) 694-3745
