rusty360 Posted March 5, 2022 Share Posted March 5, 2022 So has anyone done this? I've done plenty of high end polishing for toolmaking so I'm picking its similar. Sand sand sand thou the grades. Then buff. Quote Link to comment Share on other sites More sharing options...
a.craw4d Posted March 6, 2022 Share Posted March 6, 2022 The paint on some alloys is fairly thick. Is soda blasting first an option? 1 Quote Link to comment Share on other sites More sharing options...
rusty360 Posted March 6, 2022 Author Share Posted March 6, 2022 Yeah that's a good idea, I'm picking they are prob just rough cast underneath Quote Link to comment Share on other sites More sharing options...
a.craw4d Posted March 7, 2022 Share Posted March 7, 2022 The cast surface isn't usually too bad, a quick sand will easily level it out. Painted rims come into work quite often that look and feel really bad but sometimes it's just the paint that's chipped with little to no damage to the alloy underneath. Got any pics of the wheels in question? I like a machined finish but that's because I'm too lazy to polish. That and I don't really know how to polish alloy. 2 Quote Link to comment Share on other sites More sharing options...

I'm still amazed how true you guys get those old wheels to machine them! How much do you normally machine off? Quote Link to comment Share on other sites More sharing options...

Just the centers are paint. Quote Link to comment Share on other sites More sharing options...

How much do you normally machine off? They just go in a big 3 jaw chuck. The older wheels are a lot more rigid than all the newer crap. Never seen a cracked hotwire. Edit. Might take up to 0.3mm off the face. Sometimes 1mm off the outer lip where the worst curbing is. 2 Quote Link to comment Share on other sites More sharing options...
