[QUOTE="charles007, post: 19008, member: 9"] desertfox, I usually grab the runner bar from both ends, etc, and just lift up, on cases that large. Don't ever intentionally make the connectors small, you can always thin them down in the finishing...... As you saw, small connector may have been where the wax flexed when you pulled off the model...... If you ever see a case that might have a draw problem, wax the abutments-just dip and seal margins. Then lay a metal bur, or hard plastic sprue rod, sticky wax over the inc-occlusal.....Lift off to see if it draws without breaking the dipped waxed coping...... [/QUOTE]
