- My Current Packing. Is that an original Vandercook Mylar-Coated Underblanket?
On to my next newbie question. This is a photo of the current cylinder packing on my SP15, which has a standard .040 undercut. There are four layers:
1. Hanger : A red something that appears to be fabric coated with rubber.
2. Mylar or acetate.
3. Tympan paper.
4. Drawsheet – Tympan paper.
I’m not sure how old this setup is, but one impression on the drawsheet advertises 20-gallon plastic trashcans with domed lid for $1.40, so I am guessing it was a long time ago. The original packing list that came with the press included a Mylar Underblanket. Part number specified is X-25797, though my parts list tells me that is a Mylar Coated Underblanket for a Model 3, 4, 4T, or 215 rather than an SP15. So, I’m guessing this red blanket and transparent layer are indeed the Mylar-Coated Underblanket. But that (supposedly .018) plus the two layers of tympan, only gets me to .030, which seems pretty light, no?
I need to figure out what a newbie like me should use for packing from the git-go.
Reading Paul’s book, plus “The Gourmet Vandercook” suggests that a lot of folks are using a mylar drawsheet. I’d be interested in hearing your perspective on the pros and cons of mylar, as well as whether I should stick with the old Vandercook blanket as the hanger.
