Very rough stone flatting?

Mon Apr 28, 2014 7:10 am

I use the DMT plate to flat my stones, if the stone 24 or 60 grit (like Nubatama Ume) can I use this plate or there is other way to flat it...

You can still use it to flatten those stone's. However, if they're dished a lot.....flatten them somewhat on a sidewalk or some such first....then finish with the plate.

I wouldn't, it will chew up your diamond hone.

I have a 60 grit and don't even bother to flatten it. It's not a very good stone to begin with so I only use it to flatten other stone which it's not very good at either.

I can't imagine ever needing a 24 or 60 grit stone when any repairs or thinning can be done quickly with plates in the 140 range.

2x72 ceramic belts work way faster. :o

Actually, gluing coarse belts to a board makes for a great coarse "stone", much faster in most cases. Home Depot sells some diablo belts that work well for this.


Back on subject,
To flatten such coarse stones a lapping powder and a hard surface tends to work best. I would go with 36 grit powder.

Sidewalk is a good suggestion. I never use super coarse stones either btw. 150 Nubatama is about as low as we go with stones.

That's an awesome idea.....never thought of that.

I think I would use a drywall sanding screen as a flattener for such coarse stones. This one is 100 grit, but you can get them in 220 grit, too.
