These days I seem to be accumulating quite a lot of broken, cracked and generally munted plastic bits . No, I've not broken them myself, I've gotten them like that.
Now, in the good old days, when all bike parts were made of decent honest cast iron, fixing broken bits was easy. You welded, or brazed them up. With the trusty oxy torch. Which I can still do tolerably well.
Unfortunately, (and IMHO very ill advisedly) manufacturers seem determined to use more and more plastic and less and less cast iron nowadays.
Which leaves the question, what does one do when it gets broken ?
I know that broken plastic CAN be welded up. But I doubt that it involves an oxy torch.
I see plastic welding kits on Tardme for around 500 - 600 bucks.
But I have no idea of whether they are any good or not (it's rather a lot to pay for an experiment). And where do you get filler rods (I presume some sort of filler is required). And such like questions.
And ,and , and , generally.
Anyone know the gubbins on it.
Oh, and is it hard to do? And are the results worth it, or does it just look like crap anyway, and it would be just as well to stick with fibreglass repair kits and Araldite?
