Repairing plastic

If this is old hat then......

Just found a broken enter key on one of my 500's

the little square had busted off.. not too much trouble to stick with some Isocynate, but it looked a bit fragile with all the pounding the "enter" gets ..

So searched out this .. ( used it before to mend car keys) ..

you can find it on Fleabay..

its a fine silicate powder you can put in weak points then drip the superglue on and it sets very hard..

Re-enforce cracks, splits , etc ..

Certainly worth a look with all our old plastics.

popped a bit around the stem and drip!!. Done .

Had to trim it a bit to fit in as I was a bit generous with the powder after but all sorted .

I was told that some type of plastics are impossible to glue, and Amiga seems to be that kind.
they said, you can see if its 'bad type' by putting a drop of acetone on it. if it starts 'eating' plastic, its 'glueable'. but don't try it on valuable things, for obv reasons.

epoxy resin can glue almost all - only proper preparation of surface is required (degrease)

Yeah .. but I just can't wait hours for poxy to go hard .

Getting old .. so can't waste the time waiting for glue!

This stuff makes instant glue even more instant.. but it hard to trim if you put too much on ..
