BSF? Try uk.rec.engines.stationary

If it were metric, I'd have suggested a back-street garage or
engineering machine shop. Most people who have a Helicoil set are
happy to do one-offs for a few quid.

I'm not familiar with Durafix, but assuming it's a steel-loaded epoxy
like JB Weld, it ought to do OK.

For most purposes, any filled epoxy will do this. UK.D-I-Yers ought to
keep some decent low-viscosity epoxy around (West System do a handy
pack) and mix it up with suitable fillers as needed. On-demand filled
epoxies are _much_ more use (and cheaper) than raw resins, or pre-
thickened tubes. Almost any powdery filler will do for rebuilding
threads for attachment purposes, it's a bit harder if you care about
release afterwards, high temperatures or working life in a moving part.

Could you not use a mould release agent on the fastener's threads, so as
to get the fastener out after curing? Or does the adhesive expand when
it cures?
