Sorry for the title, I liked the pun. I would like to hear thoughts on anyone who has worked with Teflon either machining or for gasketing. I have never touched teflon aside from it being a coating but will get to machine and work with some this week. Most of the information I find online has to do with offgasing. I am also curious to get opinions on whether thin teflon gaskets inbetween three 3/4" thick teflon blocks would sufficiently seal so as to be watertight. Since I've not worked with the material before I am not sure how 'rubbery' this semi-crystalline stuff would be. I imagine it is probably the material that can be found here: http://www.mcmaster.com/#8545k72/=2y1npk Thanks!
