Tapered mandrels work best.Use a release agent like wax, soap, teflon
coating, silicone oil, low density polyethlene disolved in methylene
chloride, etc.

Not sure why, but the last few attempts at casting have resulted in stuck
mandrels. I've never had this problem before. I'm using electropolished
stainless steel tubing for a mandrel, sprayed with Pam cooking spray. This
has worked just fine in the past.
What are you guys using for mandrels and release agents?
