Herrick Posted July 2, 2021 Share Posted July 2, 2021 Has anybody ever used a Dremel to polish before painting? Link to comment Share on other sites More sharing options...
Circloy Posted July 2, 2021 Share Posted July 2, 2021 If you're talking about polishing plastic the high speed of the Dremel is more likely to destroy the surface than polish it. The heat generated does not conduct away and can result in locallised melting. 1 1 Link to comment Share on other sites More sharing options...

wombat Posted July 3, 2021 Share Posted July 3, 2021 I think there’s someone on here powers a Dremel through some kind of voltage reducer, which effectively enables control of the rpm low enough to be functional on plastic. 1 Link to comment Share on other sites More sharing options...
dnl42 Posted July 3, 2021 Share Posted July 3, 2021 Hand polishing pads are quite effective. Just remember to step through each grit. 1 Link to comment Share on other sites More sharing options...

I tried my Dremel with the lowest speed and smallest polishing pad, but it still snatched. I could see the potential for damage to the surface so stopped. I bought my Dremel years ago but have never really used it for anything constructive! Link to comment Share on other sites More sharing options...

I searched for Dremel motor speed control, but the only hits were American, so presumably wrong voltage. 1 Link to comment Share on other sites More sharing options...
wombat Posted July 4, 2021 Share Posted July 4, 2021 For small areas, I’ve got one of those “middle of Lidl” battery tooth polishers, with different grades of Wet&dry superglued to the interchangeable heads. 1 Link to comment Share on other sites More sharing options...

Tony G Posted July 8, 2021 Share Posted July 8, 2021 I knocked this up from a cheap super drug cordless electric tooth brush. Punched out discs with a 13mm hole punch (sharpened 15mm copper pipe works just as well) from various grit sanding sheets, micro-mesh and sticky back felt. I attached them with double sides tape or 13mm self-adhesive Velcro discs for a softer backing for rounded surfaces. I still have more heads to make but it seems to work quite well for sanding and polishing. Trouble is the wife keeps wanting to nick it to do her nails Link to comment Share on other sites More sharing options...
