large coarse stones recommendation

[seacucumber]

I would like recommendations for a stone that meets these guidelines please.

1. used for the relief bevel when I don't feel like setting up a belt sander
2. large, long
3. cheap
4. I plan on getting 2 so I can rub them together. If they get super dull, I can lap them with sand.
5. a hard binding, but not so hard that the grit stays dull
6. When the stones fill with steel, I'll rub them together.
7. hard grit, like silicon carbide
8. Grit particle size doesn't need to be very uniform. Occasional gashes are fine, and can be removed with my fancy stones.
9. not for the final edge

I have a sharpener that's partly homemade (on a milling machine), and is like an edge pro.
Here are my stones (edge pro size)

5 stones of Congress Tools moldmaster: 80 to 400 grit
5 stones of Shapton Glass: 29.4 micron to 1.84 mic.

I like this stone. A large 11.5"X2.5" Norton SiC coarse of 100 grit. I've had one for years and it works good and was a economical purchase. DM

I really, really like this one

I bought a couple of other white stones (trying to economize ) that were even coarser, in theory, (80 grit etc) and this Shapton Pro 120 cuts circles around them as far as not glaziing and loosing it’s cutting power.

In this photo the white coarse stone in the forground is an 80 grit and the Shapton 120 behind it is a way better cutter.



The other “fast cutter” that I was using before that and I still use it and flatten my other stones on it, ha, ha, ha, including flattening my pink stone flattening stone with the deep grooves in it which did not come flat, is this little metal eater.

Sorry they still are not as long as you asked for. If you go to the manufacuters web sites sometimes they offer larger stones than what is widely available. Mostly in the diamond plates though.

The woodworking gang taught me to go with this when I want to get a big ding out of an edge or reprofile though.

The Nubatama 60 grit comes to mind. Little softer than the 24 grit Nubatama.
