I need some help figuring out how to drill plastic/acrylic pen blanks without cracking them. I use the Rockler Pen Press/Drilling jig (http://www.rockler.com/product.cfm?page=18062&filter=pen%20vise) wirh a new sacrificial wood blank in it. I have tried both brad point bits and regular bits, both very sharp. I have tried drilling a small hole and working up to the size that I need. I have tried drilling slow and drilling fast.
The problem is when I get to the bottom where the bit is about to come thru, the bit catches and cracks or breaks of the bottom of the blank. I have thought about leaving the blank long drilling to the depth that I need and then cutting off the bottom to expose the hole but have not tried that yet.
What/how are other drilling plastic/acrylic blanks for pens?
