[SEL] Cracked Head

[Elden DuRand]

Tommy:

I'd much rather give the epoxy a try on old iron rather than weld or braze.  Too much heat stress could make the crack worse, even if it is drilled.

If the epoxy proves to not do the job on a particular project, then it's time to get out the smoke tools.

Take care - Elden
