Headley Posted May 2, 2009 Report Share Posted May 2, 2009 What sort of grinding disk should you use to grind a rim because today I found that I damaged a perfectly good disk. Quote Link to comment Share on other sites More sharing options...

Muel Posted May 2, 2009 Report Share Posted May 2, 2009 They're utter shite, the grind isn't deep at all.Metal cutting discs are by far the best I've found. Quote Link to comment Share on other sites More sharing options...
Mr Motivator Posted May 2, 2009 Report Share Posted May 2, 2009 A masonry cutting disk gives a pretty harsh grind. Quote Link to comment Share on other sites More sharing options...

Muel Posted May 2, 2009 Report Share Posted May 2, 2009 That'll be fine to do rims with, just don't use it for cutting anything hard. I once had a disc that picked up when i was cutting the sticking out threads off a reel I have in the back garden, nearly shot the grinder out of my hands and took a huge chunk out of the disc.

basher Posted May 2, 2009 Report Share Posted May 2, 2009 i deffinately wouldnt recomend using a cutting disk unless your handy with a grinder and know what your doing. cut disks have a habbit of shattering and if a piece hits you it going to be a serious injury. just use a normal grinding disk or a masonary one Quote Link to comment Share on other sites More sharing options...

Dave Anscombe Posted May 2, 2009 Report Share Posted May 2, 2009 decent mettal cutting disc ive found the 3 mm discs work best for me at giving a nice sharp grind Quote Link to comment Share on other sites More sharing options...
liam-pantera Posted May 2, 2009 Report Share Posted May 2, 2009 metal cutting disks wear really quickly but there still useable after they start to frey . if you want a slightly ruff rim for smooth pads use a mop disk to sand the surface but if your after a really deep sharp grind use a cutting disk stainless or mild steel it doesn't really matter .

DannyBazz (: Posted May 3, 2009 Report Share Posted May 3, 2009 When I ground my rim, I used a stone cutting disc, but sharpened it on an old rim first, had no problems, and a nice medium ground rim. Think there is something on the wiki about sharpening discs... Quote Link to comment Share on other sites More sharing options...
Mike W Posted May 3, 2009 Report Share Posted May 3, 2009 Dont use that disc its damaged, if it bursts anything could happen.i reccomend getting yourself a new metal grinding disc or grinding it with a hacksaw Quote Link to comment Share on other sites More sharing options...
