Any Polishing Experts on Here?
Discussion
I have around 1000 polycarbonate wine glasses which over time have scratches (not very deep) over them and I can't use anymore.
As they are worth about £1.80 each I was thinking of one of those table mounted polishing wheels with some sort of polishing compound and a suitable disk. I could present the glass to the wheel, rather than clamp the glass and have a hand polishing machine.
Anyone have any suggestions of what I would need? I have heard that if it spins too fast it can heat up the plastic too much and damage it.
Does not need to get it back to 100% clear of scratches, just get most of them out. So ideally one pass on the machine.

You would have to experiment with the grit of the polishing compound to get a balance between removing enough of the scratches and not taking too much time.
I think it would be difficult to make it really efficient with a wine glass because you're going to want to put a high polish on them so you may need to use more than one compound.
You could easily end up spending a lot of time on them and them still not looking great.

Thanks, its only the outside with the scratches, its where the glasses have knocked together. They don't have to be perfect.
I was thinking of a duel disk machine, with one compound on each but I have no idea where to start with a machine or compound. I was thinking each glass would take 2mins?
Its a job I would do in the evening, its not just greener but also saving significant money.

I'm certainly no expert, bit I would be looking at a solution that involves the glass rotating. Maybe something like a mini porters wheel that you could fix a set of quick release clamps to.
Figure out a process flow on a few sacrificial glasses, aiming to minimise time. E.g. 30 secs medium, 30 secs fine, final polish.
Then set up with 1st stage compound and do the lot, then move to second stage for the whole lot. Think yourself lucky if you get 80-90% out the other side!
Bizarrely I could quote enjoy doing something like that, listening to Radio 4 the world just carrying on around me.

Word of warning. They will eventually degrade again.
Not exactly sure of the chemistry behind it, but this can be done to black plastics on cars that have gone all hazy/grey. Works for a short time but is damaging to the plastic overall. Still, at least you'll get a bit more use out of them.
