Fixing plastics

[Jaz66]

seen a few posts re panel with broken lugs etc, and i know these are hard to find and can be expensive to replace,
so i was quite intrigued when i saw this post on another forum.



Copied the link in case it is of interest to any one else.

Great find Jaz.

Just in case they ever tidy up I thought it would be rude not to go collecting.

By a chap called Virus

get a jam jar, put a teaspoon or 2 of acetone (nail varnish remover) in it, then drop a lego block (see colour coded this nuts is) into the acetone.


when the lego block is melted, use the goop to make your repair and leave it to dry overnight in a warm place.

Nice hot soldering iron to melt the parts back together and some plastic to use as filler material (thin slithers from discrete places work),

Then if you want to you can reenforce with epoxy resin, fibre glass etc,

Then if you want use sealing adhesive like siklaflex, tigerseal etc, rush/spread it on nice and thick on weak edges to help strengthen but keep flexability, using a heavy duty sealer over the repair helps to keep the bits in one piece if ever you drop the bike again too.

I did try this with melted pen which worked well

Wow - the lego brick in acetone sounds great.

I have tried the soldering iron and a "filler rod" of plastic and it works pretty well, provided you're trying to mend the right type of plastic (thermo plastic)
Just be aware of fumes coming off and hot molten plastic that might drip everwhere
