[QUOTE="JohnWilson, post: 330733, member: 213"] Patrick nailed it here. We have to remember when we are cementing using a resin cement that it is composite and well we all know composit on its own does not stick to PMMA natively. Painting the intaglio of the PMMA pattern with a PMMA to composite bonder is the best way to achieve a bond. Adding mechanical retention to the pattern is also something that will be of great benefit and is something I have been doing for years by hand. What I have been working on is to automate this process in CAM with a Thread cutting tool and I almost have it dialed in perfect on my PM7 [/QUOTE]
