So, is there any way you could brace the joint, even if only on one
side with something suitable (steel strip / sheet / rod etc)?


Sadly the shape and size prohibit this.

What about drilling and pegging each end of the joint? It wouldn't
have to be *that* accurate if you have enough 'meat' to drill into and
use a suitable epoxy.

I am going to try some alterative solvents to remove the remaining glue before trying Araldite.

As (chemically) clean as possible is a good start, as might be a
*little* warmth.

Whilst Araldite used to be the go-to adhesive for many things (esp the
24 hr stuff if it really needs to be strong), personally I would first
try something like JB Weld two part epoxy on the grounds that if that
won't hold it, not much else will.

Std 24 hour Araldite is just a good two part resin, the JB Weld is
reinforced, providing a stronger bond as it's less likely to compress
on the side with compression loads and so tear away the rest of the
bond.

I will try to use a clamp.

Anything that will stop it moving whilst it cures is essential.

Once cured, some of these adhesives also enjoy further curing with
some external heat (but don't go mad). ;-)

Thank you for your advice. Believe it or not there is oly ond syockist of JBWeld in the Greater London area. I am going to try the two-part Gorilla again, having checked all the comparative reviews.

I di think of drilling and pinning but holding a small piece of solid Alli and drilling through 3mm or so would require the kind of gear that I don't have. My Dad could have done it. He was fine engineer but I no longer have access to all his tools.

Despite my initial cleaning attempts, first with petrol and next with hand gel, I am still not confident that the edges are clean. I need another solvent to get rid of what I suspect was poorly cured adhesive.
