Thread: Finishing Stone Question

Yup, looks like a well-used Washita, with a swayback.

It will take some work to flatten with 60 grit. But doable and worth the effort.

Nice stone what are the dimensions?

I don't have a tape measure readily available, but here's a reference.

Would it be possible to just use 60 grit sandpaper taped to a jointer? I don't have a stone more rough than the Norton flattening stone.

Sandpaper is doable but no where near as fast or cheap as loose SIC. In a pinch it will do it.

Nice stone, I love those smooth washitas.

I did my last one with 60 grt. paper. Its gonna take a few sheets. ( a whole pack ). And a crap bucket if elbow grease.

Mine had to soak for several weeks.

Cheap 60 grit Wet & Dry is $20-30 per 50 pack. Good 3m paper is $110. Good sandpaper is worth the extra price.
As said, you will burn through a pack, especially as worn as you stone appears to be, probably need to remove at least an 1/8 inch of stone.

Remember to flatten a stone you must remove all the stone, down to the lowest part of the deepest pit.

Sandpaper is way more work, you are looking at hours of work. Lose 60 grit Silicone Carbide will get you to flat in about 20-30 minutes. A ¼ pound of 60 grit is $4.40.

It can be done, it is your choice.

Correction, a full pound of 60 grit Silicone Carbide is $4.40. Way more that you will need.

Thanks! 1 lb of the 60 grit and then 1/4lb of all the others up to 550 grit is still just under $15. Plus shipping and the time saved I think will be well worth it.

I appreciate the advice. <3

Get a cheap steel cookie sheet from a dollar store and find a smooth piece of cement floor. Sprinkle on a teaspoon of grit and squirt of water and use you body weight, spin the stone frequently, add grit as needed.

You will feel when it stops cutting. When you get a thick slurry wash the sheet off, I just wash it on to the lawn, not down the drain.

If you haven't already I would pop it out of the old box it is in. Could be the other side is flat and nice.

OMG brilliant! I'm sure I can do the same with the strop as well!
