Jammy123 Posted December 23, 2008 Share Posted December 23, 2008 I have just fitted a HD Bumper from Paddocks, came to fit the Alu steering guard which they said would fit and it doesn't! Now I need to grind about 5mm off each side, is it ok to use a 'normal' grinding disc marked 'metal' or do I need a special disk?

techtone Posted December 23, 2008 Share Posted December 23, 2008 If I were you I'd take a jigsaw to it if you can..... likely to be quicker in the long run! Tony Quote Link to comment Share on other sites More sharing options...
bishbosh Posted December 23, 2008 Share Posted December 23, 2008 A metal grinding disk will be fine, but you might want to use a flap wheel as that will be much quicker and result in a tidier job. Quote Link to comment Share on other sites More sharing options...
carl hurst Posted December 23, 2008 Share Posted December 23, 2008 If you use a flap wheel put some tallow or candle wax on to help stop clogging, Carl. Quote Link to comment Share on other sites More sharing options...

landmannnn Posted December 23, 2008 Share Posted December 23, 2008 You shouldn't need to grind aluminium since it is not hardened (although it can be in specialist applications). There are 4 dangers, first the disc gets clogged, and where aluminium is rubbing aluminium the heat generated could cause the disc to shatter, the second danger is a disc that has previously ground steel (or using for steel afterwards) - a thermite reation could take place which is a bang and a shattered disc, the third is that aluminium dust is can explode with a heat source and the fourth is that the dust is toxic. All the above are not very likely on a little job at home. Nor is winning the lottery (I know a two people who have though). Suggest you get your saw out.

FridgeFreezer Posted December 23, 2008 Share Posted December 23, 2008 As above, the thin (1mm or thinner) cutting discs, followed by a flap wheel. Quote Link to comment Share on other sites More sharing options...
Jammy123 Posted December 24, 2008 Author Share Posted December 24, 2008 Cheers, I can get to use the really thin cutting discs that go on an air powered grinder but not till feb, so I shall use my dads leccy grinder with a flappy disc on boxing day when i see him!
