Nah, it's a Liquid Metal Filler and you can file, grind, drill
and thread it.

Would be good to have that gear, but for a pensioner it's just
another pipe dream.

There's enough face material left to work with for my needs.

The Permatex should suffice for that (hope so anyway).

I try *hard* for original first, then empty the bucket on the
tarp. :-)

Then beg my mechanic mate for the use of his lathe. :-)

We (pensioners) also like bartering. ;-)

Would've thought anyone who restores old stuff would need to have
access to oxy gear... even pensioners. The rest is straightforward,
since you've already got a valve refacer. :)

I'm betting it won't! Think you'll find the temperature rating will
peclude it and nor will it contribute anything to the strength, even
if it will stand the temperatures involved.

Other alternative would be to get a welding shop to powder spray the
stem (and the face while they're at it). It's not recommended for
high speed engines (because of the risk of head separation) but should
last a lifetime on a low revving stationary engine. Nor should it be
particularly expensive even if they don't have a special rate for
scrounge... er, pensioners. ;-)

Only the two pack paint engine restorers have the good gear.
We working clothe restorers learn to make do.

Did you attend the Noddy School of Reading? I have access to
my mechanics valve refacer (after I repair it - remember).

I will find out, won't I. :-)

Whatever. I wish you well in your retirement too. :-P

Just find and machine another valve , reading the specs it (permatex)
certainly does not look up to the job ( although a good spray would)
