How can I smooth the trackball plexiglass hole? (ouch! it's sharp)
<< < (3/7) > >>

Ok, what grit sandpaper should I buy?

Any other tips for sanding the edge of the hole?  Maybe I should cut a strip of sandpaper so that I only have a little bit of sandpaper exposed to the plexiglass?

Oh... and does Home Depot sell any polishing stuff I could buy for after I've sanded the hole?

LOL.... Sorry, I'm in a mood.  I would cut the paper down to a reasonable size.  This will keep you from scuffing areas you don't want to hit.  Here is the polishing compound that was mentioned in this earlier thread you started.  Not sure if it would be available at Home Depot.

mask off the area sorrounding the lip with masking tape etc so that you don't scuff the area sorrounding the hole..just leave a tiny gap around the diameter of the hole for sanding back
sofakng:
Excellent tips, thank you!

What grit sand paper should I use?

...and what type of tape should I use?  I don't want to use something that will stick to the plexiglass and won't come off cleanly...

Thanks again everybody!

As I stated, I would use 200 grit. Masking off the area is an excellent suggestion. Regular masking tape will work and it shouldn't leave any residue. But if it does, it can easily be cleaned.

You can cut the paper to size or just fold it in a manner to leave a small are exposed. I prefer folding it as it gives you a bit more bulk to hold onto.
