Thanks for the explanation Shortrnd. It looks like I'm going to start getting busy on these kits that have been sitting around for a while. This evening I sat down for a couple of hours and drew a 1919 RSP in Solid Edge. I plan on dumping it into MasterCam in the next few weeks and working out the tool paths. It should be easy from there...need a to pick up a few new cutters though. What do you guys think about my solid models?
