Thomas Rubino : There is a type of High Temperature rope gasket material that comes in various circumferences/diameters with a removable core,
the direct person I could ask is out of touch on the west coast. To use this gasket material you actually tease out the core and use the now skinny flat
Gasket material to make a final seal. There is an original food grade gasket material that must be removed 1st !
I do know that you
should be able to find the material thru an
online search of the hardware chains .Alternately Ernie W. has been alleged to have
made a gasket out of the dough like mass of ''Wonder Bread ", I never saw Ernie do this and I AM Not putting words in his mouth,just repeating an
apocryphal tale
Tile should work well everywhere, being a denser mass they should store a little more heat
energy (at the same temp) and feel warmer !
If you can find tile with coat hooks, (or just place a lag screw into the cob just above) you will have a great spot for Drying/warming gloves !
Late note : R. Scott's rope gasket looks exactly like what i was talking about ! Cob is a possible work-around but in my house it would be a 'shit',' I
dont have any cob made, I can't clean the Rocket today!' Thought that one through, after you find the right sized gasket get a back up
Good Luck ! Big Al
