We solved the bridge issue we were having a while back, but its now happening again. Ive been using the stabilizer bar feature in Sum3D, and it seems to help somewhat, but these little bastards have begun to rock again. I suspect its the same issue as before (waxers carelessly spruing).....so I decided to leave the connectors kind of long when cutting the bridge off of the wax ring......this allows the waxers to sprue the bridges without getting their hot wax too close to the bridge itself. It seemed to work for a while. But now they rock like crazy again. Also having issues with the cement gap, as one setting doesnt mill out enough, it the dies wont seat and I have to use a high speed to dig it out. Then the next setting they fit a little loose after we make an adjustment. Its getting frustrating and the guy who came here to teach us this stuff from Zahn was kind of a goof ball and simply could not help us with any tips. Starting to winder if this stuff was even worth it. Any help from your experience would be appreciated.
