Talk Morgan Forums Community The Malvern Arms Aluminium glue

I have a morgan based project on the go. I need to glue an aluminium block to an aluminium sheet. I have tried araldite on a properly cleaned and scored surfaces but it has failed. Is there something else out there that is better? It needs to be obtainable from the usual sources

thanks in advance.

Lumiweld?

I've used this in the past with good results:-

How much strength is needed ?
I have used JB Weld on fairly low stressed fixings and added brackets for extra strength use where possible.
The key (excuse the pun) is surface prep, clean and roughness/smoothness of mating surfaces being important.

Did you use Araldite metal repair?

Or just the standard epoxy?

Depending on size of block and sheet why not drill tap and use a countersunk screw?

That's the other one I couldn't remember...

Believe it or not I have used JB Weld on a cast iron exhaust manifold back in the day. It was on a Rover V8 and a couple of the flanges had broken off.
Not only did it stick the metal together, when I replaced the manifolds with tubulars, the cast maifolds were still intact and I sold them on, and they continued to hold.
Remarkable because this is well outside the performance envelope.

JB Weld is probably the highest temperature epoxy resin glue - certainly was when I looked into the issue. Good enough for a non-combustion chamber repair to an engine block.

There are two grades of Araldite, the stuff that sets in few minutes, and the traditional wait 24 hours one. The latter is of course stronger, but the quick one has its uses for things one might want to take apart again as if you can boil the object in detergenty water, the epoxy becomes like cheese.

But you'll never have any success with any kind of glue if you don't thoroughly degrease the surfaces first. I generally tell folk, 'do it properly, and then do it again'. Epoxy should stick aluminium no problem, and without trying for myself, I would suspect a surface that was still slightly greasy in the event of failure.

Thanks chaps. i will try JB Weld and see how it goes.

3m panel adhesive is the only thing I could recommend... it is designed specifically for what you are doing, it is used to bond new cars together as well as for the bodywork industry to do repairs.
