Re: Tapping Shapeways high def plastic


I drilled and tapped a Shapeways San Juan car floor for 0-80 screws. I used Grobet Pro Cut on the drill and tap. I used a 'fresh' tap rather than one which had already tapped 100+ holes in 1/8 acrylic. I was pleased with the results.

Keep in mind if you intend to use the Blackstone provided screws they are metric 1.7 diameter, .35 pitch. These are not compatible with 0-80 diameter and pitch threads. I just attempted to thread a Blackstone 1.7 screw into several 0-80 nuts without success. I guess this is what happens when you try to put a .064" diameter screw into a threaded hole made for a .059" diameter screw.
