That is impressive. I have some old discolored and scratched mirrors I'm going to experiment on. Have to get another heat gun first.

Flame on!

Very old stuff. Was described in several motorcycle newspapers I guess ten years ago.
I learned it about 15-20 years ago from a friend (mechanic).
For smaller parts, it's more precise to use a (EDIT: Thanks to Bubba, see below) soldering bolt instead of that flame thrower, also.

But when only some folks here didn't know it, this thread is a winner. Thanks to Peter.

You must have lost something in the translation, Lars. A welding rod versus a shrink wrap heater?? Did you mean a torch?

Thanks Bubba,

it was not translation, I was lost in thoughts about a different problem and simply typed down a wrong word.

The right word was surely "soldering bolt".

If you want to repair broken plastic materials, you'll first use the soldering bolt to "glue" the broken parts together and then use some thin stripes cut out of the same material as a kind of a welding rod together with the soldering bolt to get the pieces back together. That's also a kind of welding.

If you still don't get it, then it really must be a damn translation problem. I've repaired quite a lot of plastic things this way, 100% successfully, but you can't apply this method to all kind of plastics. That's one thing you have to know first - the precise material that has to be repaired and its characteristics.

The selfmade airbox of my R1200S, using the stock part (PP-GF30) as basic , was made the same way in May/June 2009. It still works.

A picture is worth a thousand translations, Lars Got a photo of a soldering bolt?

[Sofatester]

You don't mean my personal one but the electric device ?
Well that device can be seen in the second video link in Peters first posting at ~ 3:45 min.

I used that method to reattach the nut plates to the back of the side panels on my R11S.
