Folks, JB Weld seems to be highly rated on here and other places. Which is the recommended version?


Cheers,

cliffa.

I used to carry the 15 minute variety to the track in my spares kit for quick fixes like repairing cracked fuel tanks or crankcases. I've used it for both:rolleyes:, but considered it just a short term fix to get through a race. I've seen it used to fix a fuel tank crack (Rickman Norton) and last for years, but I wouldn't feel comfortable with that.

For other uses, I just use the regular stuff that takes longer to cure.

What's the 'regular stuff'? And can it be used to repair the damaged threads on the top of an Atlas cylinder head? The one that holds the head steady plate. I'm in the process of restoring my '64, and when it came into my hands the threads were already knackered.

A head steady likely will beat ANY JB Weld to a pulp. Why not re-thread it and either use a bigger bolt, or a thread insert/helicoil?

Hi Ken, thanks for the info. Just to confirm ( as they seem to have a lot of versions) you mean this one?

No chance. Unless you enjoy removing and replacing the cylinder head !

A proper mechanical repair is needed, as per JS comments.

Thanks to both for your advice. The insert sounds the way to go. I'm taking the major parts to a machine shop soon. I'm sure they can help me figure out a proper solution.

Yes, that's the one I called "the regular one". Back when I first started using JB Weld in the early '70s, that was all they offered. The "15-minute" cure stuff was added later. I hadn't kept up with all the huge variety of new products they now offer, so didn't realize there would be any confusion. I've just looked at their web site, and I think what they call the KwikWeld is what they used to call 15-minute cure.
