belt grits

marekz · May 23, 2009

what are the most common belt grits that you use. Im looking to stock up on some belts and im thinking if i had to choose 3 grits it would be 60 grit, 18o grit, and 220 grit. and i quess i would want some 400 grit also. would it be ok to go from 60 grit to 220 grit? or do i need something in the middle--thanks marekz

If you want to get rid of the 60g scratches then you go to 120-180-220 staying with each grit until the larger scratches have disappeared. Good luck, I started 66 years ago with an old farm peddle grinder. It has been a world of fun.

I go 80, 120, 220 but i am using a bandsaw for initial removal. After ht another 220, then to 400 and up if needed.

My standard rotation is 60 grit to 220 grit to 400 grit to 800 grit.
hope this helps

marekz,

Right now, the 4 most common grits I use are:

3M 36 grit Aluminum Oxide X weight
3M 120 grit Aluminum Oxide X weight
3M 240 grit Aluminum Oxide J Weight
3M 320 grit Aluminum Oxide J weight

Sometimes, I go directly to hand sanding after the 240 grit. It depends on how steady a grind I've completed up till that point.

40 for profiling and flattening, 80 for rough grinding the bevels, followed by 120 - 220 - 400 - Trizact A45 - A16. Then hand sanding from 240 to 1000 or 2000...
