Unfortunatly Jeff explained to me at the moment he can only coil to a diameter of 9.5 inches as I guess the other mold or whatever he uses was decommissioned recently so I don't know what I'm gonna do right now
It is 9"x8". There are actually two coils, 3/8" outside and 1/4" inside. I can cut the 1/4" tubing and remove it. It was some sort of IC at one time. I picked up two of these in a trade, and I'm using one on my set-up.
