Just a thank-you to the list. I accidentally broke the top to a very
nice filing box I've been using for years (it was designed for
floppies, I think, but I now use it for paper - 8" floppies, I suspect,
since an 8?" paper sheet just barely fits).
Turns out acetone dissolves the plastic, and I was able to solvent-weld
the pieces back together with acetone. I let it dry over the weekend
and now it is all good.
But I never would have thought to try that without all the discussions
of such things here on the list. Hence the thanks. Neat the ways
knowledge finds unexpected application!

Great that it worked for you, but be advised that acetone will also
(in my experience) turn some plastics into grainy mush, so it's not
a universal solution for plastics.

Well, I did first try applying acetone to a noncritical area of the
same part, to see what it would do.

Yes, methylene chloride is the proper plastic solvent for styrene

other than at the contact point. This is the stuff they use in
plastic shops...along with some other solvents.

Has anyone found a solvent that will solidly weld the PC+ABS blends yet? I
run into various blends of PC+ABS all the time and have yet to find
anything that will work well. Methylene Chloride will melt the ABS part of
the blend, but it makes a brittle joint.

I don't know if it;s the same stuff, but _good_ model shops in the UK
sell something branded 'Plastic Weld'. It seems to be mostly methelyne
chloride and is what I sue for repairing broken computer cases, etc.
