Folks,
Thanks to the help of the Turkish Navy, we have a drawing of the gasket from 1951 built ex-USS Tang, then TCG Pirireis. Of course this could be different than what we have on USS Pampanito, but it looks very close to the dimensions of the USS Cobia modifications to her torpedo tube drawings.
http://maritime.org/tech/drawings/torpedo-muzzle-door-gasket-from-usstang-tcgpirireis.jpgWe are hoping to open #1 tube on Pampanito sometime in the fall (it is above the waterline, inner door will be shut.) We can then confirm the dimensions before creating a soft (aluminum) tool to mold the gaskets.
Does anyone have a crew member that speaks Turkish, particularly with a tech. background. Most of this is pretty obvious from context and google translate, but a true Turkish speaker translating it would help.
Please stay in touch. The more gaskets we produce at one time, the lower the per submarine cost will be.
