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.

I use steel stik version have used it to fix copy machine at office and other stuff on bikes/tractor
 
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.

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.

Thanks again Ken.
 
I like the JB Marine Weld. Works on anything- fuel tanks, bodywork, what have you.
 
Fast curing epoxies, the Five Minute types, are generally less strong, less adhere nt and softer setting than 3 or 24 hr setting types. The fast types have their uses, but whenever you need max capability out of it use the slow set types.
 
JBW has its place but for major repairs to threads or any other thing that can be easily fixed doing the right job, in all my years of riding and owning British motorcycles I have only used JBW once and that was only for a short term fix instead of a quick fix and keep your fingers crossed, but there are other products around that works even better than JBW, I have been using one for over 40 years its always in my workshop or when traveling in the 4x4, it sets harder than JBW and will dry on leaking fuel tanks to stop them leaking and to my experience it works so much better than JBW and will last long term and set as hard as steel, can be mixed in water to get a smoother finish, its designed for cast iron pipes and it comes in A and B packs and the two tins will last a life time of uses unless you lend it to someone to never see it again.
My little secret product that has been around for a very long time that not many people know about and most major plumbing hardware store will stock it or order it in, it might be for cast iron pipes but it has so much more uses, it use to be called Fropite or something like that but has now gone through a name change about 20 years ago when I had to replace my borrowed tins that never came back home.
But the best fix is fixing things the right way instead of short term fixes that could let you down and that is usually while you are on the road and far away from home.

I only just got up to my shed, what I use is called JENCO its a joining putty compound used for fitting cast iron pipes and fittings etc. but as I say it sets as hard as steel, can drill it and tap it and over 40 years of using this stuff I have done many repairs that have lasted forever and for leaking fuel tanks its the best thing I have used for on road repairs even with fuel leaking it sets pretty quick.

Ferropre is the original name that I first used over 40 years ago, and when I had to replace my borrowed cans 20 years later they only had the Jenco brand, but just googling they still make the Ferropre Genuine, but of course the manufacture of Ferropre are claiming theirs is stronger than the Jenco product but I have used both and in my opinion they are the same in everything.
