[QUOTE="Accutech, post: 321748, member: 981"] I’m not familiar with jp vest but when I press I do the following. I never use debubblizer. I find too many issues with it. Lots of orange peel texture after pressing. After I invest, I wait until the ring is completely dry. I don’t work in a ‘rushed’ environment so I don’t have the need to fast press. I place the invested ring into a cold furnace and raise temp to 400C, then 25 minute hold. Then raise to final temp, 850C and hold for another 45 minutes. Then place into pressing furnace. it works great for me. RARELY have mispress issues or cracked rings. YMMV. Thomas. [/QUOTE]
