Hi,

Can anyone suggest the best type of glue to fix the arm of a pair of
metal framed glasses? One side arm has come away by the hinge point
but it is not the hinge that is broken. The arm has a small hole and
by the hinge there is a small pin which fits into the hole in the arm.

I've tried epoxy resin, but it only lasted a couple of weeks before
coming away again.

TIA, Mark.

It is almost impossible to repair any metal to metal join with glue, to
match the origial metal strength.

Possibly the best is the sort of car body filler sold as JB weld or
liquid metal. Its better than commercial DIY epoxy, which needs a bit of
heat to cure well, and very careful mixing to do its best.

However what you probably need is a splint.,.glass or carbon fibre tape,
soaked in polyester resin or similar. Or a short lenght of carbon fibre
tube over the parts.
