Re: Glue for plastic
I’ve had success repairing Psion organiser hinges with superglue. The break is a narrow strip of plastic with a lot of strain, and I’ve not found a solvent adhesive which works.
Butt join the broken parts with “neat” superglue. This gets the part in its correct position, but the fix is very weak.
Make a “fillet” of superglue around the break, the glue is a reasonably viscous liquid at this point, and easy to shape. Now sprinkle superglue filler powder onto the superglue - the glue and powder mix hardens very quickly, and makes a strong joint.
The filler powder is readily available, and sold, amongst other things, for repairing plastic car bumpers, so should be reasonably effective. I believe baking powder works in a similar way, but I haven’t tried it - maybe someone on here has knowledge of the chemistry involved.
