Aukai, do you have a belt sander? If so, the 60 grit will work. I used the 36 grit to shape and the 80 grit to finish. The 36 grit cuts fast! I think the 60 grit will work, albeit slower.
Whoops I totally forgot about this
Mikey: can you shoot me your mailing address, I'd like to shoot out the 3dp example tools to you to see if you think anything should be added or any lightbulbs go off before I make any for anyone
Now I want to build a 2x72 belt grinder when I have a chance.
