hpfiend Posted May 11, 2012 Report Share Posted May 11, 2012 Hey all- What do you use to grind large quantities of mild steel? I cut all the brackets off this ford 8.8 with a cut off wheel and oxy/acetylene torch but I still have about a 1/4" before I hit the axle tube that I need to remove. I bought the most coarse blue-green flapper wheels that the hardware store had and it is still taking forever and going through them quickly... I have 6 to grind down about 4" long by 1/2" wide by 1/4" thick.... Will one of those 40-60.00 diamond wheels do it? I don't like how much they cost but if it lasts a really long time it might be worth it... they are made for concrete and granite though...dunno about their steel rating. I am using electric harbor freight 4.5" angle grinder and I have a makita as well- both seem to work about the same... I have a few cheap air grinders as well but as of right now don't have a good enough air supply to run them... Quote Link to comment Share on other sites More sharing options...
ross Posted May 11, 2012 Report Share Posted May 11, 2012 Just use a normal grinding wheel. A tigerpaw is for finishing it off to smooth the surface so you don't have chatter marks left over. Quote Link to comment Share on other sites More sharing options...
schmuckingham Posted May 11, 2012 Report Share Posted May 11, 2012 I like to use flap wheels of varying grits, takes a little longer sometimes but you have good control and a smooth look afterwards Quote Link to comment Share on other sites More sharing options...

The grinding wheels I have are really slow and like firebush said it is easier not to gouge with the flapper wheel...- the flapper takes off more material but wears out quickly... I guess I just better suck it up and keep going... I am talking probably 4 solid hours of grinding. Is a diamond wheel what you are referring to as a tiger paw?

turboking15 Posted May 11, 2012 Report Share Posted May 11, 2012 When i cut the brackets off of my 8.8 i used the solid 40 grit grinding wheels that came from harbor freight then finished it off with the flapper sanding wheels. Heres how mine turned out. http://i200.photobucket.com/albums/aa158/turboking11/2012-01-14_00-51-28_413.jpg this thing was real nasty too as i pulled it from an explorer in a junk yard.

This is exactly what I do once I plasma or torch something off. Is a diamond wheel what you are referring to as a tiger paw? Nope. I just call them tiger paws because this is the brand we use to use at work when we ran out of metabo brand stuff. http://images.craigslist.org/5Gd5K75F23n93Fd3N5c3t69e504d0acf61fe9.jpg Quote Link to comment Share on other sites More sharing options...
