Polishing acrylic

Has anyone had any luck with polishing acrylic edges with a buffing wheel? I picked up a 6" buffing disk for grinder and when I run the edges of my acrylic thru it, I’m not really satisfied with the result. Small areas look like they smoothed out, but not on a whole like I was expecting.

I"ve seen video’s where people use those and end up with a mirror-like reflection so maybe I’m missing something. I saw one video on youtube by a Chinese lady and it looked like they treated their buffing wheel with chalk before they used it. I’m not sure if that is normal or not.

Any suggestions? I tried using a flame, but that just didn’t work out that great for me.



Not chalk. polishing rouge



I know this is more expensive than MAPP or propane but is a fascinating tool with many more uses than polishing acrylic.

nice to know ideas for this

hho generators are pretty simple in design and build from everyday parts. And if you assembled and set up your xcarve then this is a very simple task. just remember to use a a flash back arrestor at very least.

@ShaneBell After finding the HHO generator, I found a bunch of info available and some great videos on YouTube. It does seem easy to DIY but then again working with hydrogen, I would rather have one that has been designed and manufactured by a professional!


You can smooth them out nicely with fine grit sand paper and plastic polishing.
You need to work your way down to finer grit, 800-1200grit area and the polish for smooth surface. Novus is a brand name of plastic cleaner (3 steps with light abrasive steps followed by polish/shine)

Something about the warnings make me a little nervous…
