As title implies, have section for old ED pen where some idiot looks to have tried to K/O feed & nib using-- I kid you not-- a phillips head screw driver!
Must've slipped on the moron because threaded part of section has crack running right down the middle.
Googled solvents for Vulcanized rubber, but not chemistry major & info. seems to be more about recyling old tires into solution.
Question then: Anyone know of solvent, or compound that when painted on inside of section would melt or seal it without distorting shape of course.
The short answer is your search turned up zip is because there isn't anything that will work as a chemical weld on hard rubber. Even if the section were celluloid and COULD be chemically welded the stresses the section are under via the nib/feed are considerable for such thin material and not a weld I'd be likely to trust as far as I could throw it. Your best bet is to source a new section at a show or through WTB posts. Unless it's a really rare one you should be able to track one down. I'd start over on FPB.

Yeah, that might explain arcane lingo about polymers & sulfur bonds, etc.
Shame someone would just go off on a half-butt approach to servicing a pen (or whatever he was attempting to do.) Clean it? Nib was good so don't know why was trying to take section/feed/nib apart.
Get thee a K/O kit!
Anyway, thanks for clarification on BHR. Guess it's a write off. To FPB, FPN, or some discreet inquiries I go!

BTW: nice work on 'customized' pens from other reply. Liked the gold overlay.
