If you can't slow it enough, can you spray-cool when drilling plastic? I forget if you'd want wood bit or metal bit for this ? If this particular acrylic machines at all like Lucite™ (only acrylic i've machined, in a prior century!), it also wants to be machined with its protective adhesiver-paper cover still on, it helps prevents chipping. If you don't have a cover layer, shelf-paper or packing-tape might temporarily replace it ? -- Bill Ricker bill.n1...@gmail.com https://www.linkedin.com/in/n1vux _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
