[Closed] What glue for...

Polystyrene cement maybe? The stukk you use for Airfix kits. (Other kits are also available)

Ah yes, of course!

I have an aborted airfix model on the shelf so there must be glue for it.

Unless I aborted it due to running out of glue...

Cheers

I accept no responsibility for you melting the pot with the glue, burning your house down or having an amp which is now stuck on 11.

If you have a small drill I'd drill into the centre of both bits of the plastic and use a small piece of stiff metal, Eg paperclip, in both the holes, all epoxied together.

although depends on diameter of the plastic as to whether this is possible or not

My amp doesn't go [i]below[/i] 11.

Good idea meeeeeee, I have epoxie. Not sure how I can secure it in situ tho...

Just heat the paperclip piece up so it melts is way in to the plastic.

I'd just heat the plastic to make the joint too.

I've attempted this using various methods... In the end it's easier to get a new one from maplin and replace the whole unit.

Different plastics respond differently to glues too... model glue (polystyrene cement) isn't great on some, it's not a glue in the traditional sense and depends on the material reacting. Wouldn't want to guess what material that is but acetone welding's effective on a pretty wide range or materials.

And yep, drilling or otherwise pinning will give it strength. If you can weld it, and it goes well, and you pin it after then it'll be stronger than it was originally. Which obviously wasn't that strong. Much stronger than epoxy.

Much stronger than epoxy.

If the surfaces are correctly prepared and the glue/mix is good, I doubt this is true.

Pinning is very tricky as alignment is difficult and even then you'll need to bond the pin in, if you still want to glue it then use polyofin primer and super glue and try to align it, we have cut slots in the past and used thin fr4 to splice the shafts if the pot cannot be replaced but it's a real faff and takes a while.
