[QUOTE="HonestAbe, post: 341624, member: 25390"] Finally got a chance to try Ron's sample wax puck (ty again Ron!). So far so good, the margins are definitely better than the other wax puck we had, and less fragile over all. Out of the 8 or so I've milled, one of them I had to cut away the margins and rewax them because they weren't quite good enough. The tech that does the metal finishing has only gotten her hands on a few after being cast so I'm still getting feedback about that, but casting another 4 today. I'm doing everything with the margins facing the right way now, and that's been a nice improvement (thanks for the feedback there to everyone). I think I somehow messed up my math on the gold estimate last cast and barely had the reservoir filled but the crowns came out fine. Since starting this thread and incorporating the advice given I've had zero porosity issues (knock on wood) and just an easier time getting things to go smoothly. [/QUOTE]
