Sharpening wheel

[AnotherBueller]

Bench grinders can take the temper out of the steel. Pedal may sound like fun but would get old fast. You can easily add a pulley and electric motor. Repurpose a belt guard for water, putting it on the bottm of the wheel.

If I recall correctly the water/oil can dripped just past TDC on the wheel.

Build a wooden tub that will hold water for lubricating the wheel and attach it under the wheel so the wheel rotates through it.

With the old sandstone wheels, I don't like the idea of having the bottom part of the wheel soaking in water when not in use, I think it might make the wheel soft in that spot.

Good morning, does anyone here have any experience with these stones?
I know nothing about them but have been looking for something that will put an edge on my axes etc.
I’m assuming there are different varieties of stone?
Seller has told me that it’s not perfectly round as in it’s probably not intended for high speed.
It is pedal operated.
Ideally I’d like to be able to sharpen mower blades, chisels whatever with it but maybe these just were not intended for this purpose?
It’s about 2 hrs from me and he says 80 dollars
Worth it? What problems do I need to watch out for?
Thanks

I use one when I was younger on the farm. They are great because they don't turn super fast. Bench grinder is to fast for axes and other cutting tools. It heats the metal to much. Don't know if you can even buy a stone like that now. Check the stone out carefully and look for cracks especially near the hub. Stone needs to be run in water. We always made a trough out of an old inner tube and kept water in it. We had hand crank and some with a pedal. The pedal is easier. If stone has not been used in a while I would let it soak in water for a couple of days before using. At $80 I think it is a good buy. If I was closer I would buy it. Check at the hardware store and see if you can buy the stones and check the price. I think you will be surprised.

If you can, I doubt I'd like the price.

Crankshaft grinders still use big wheels like that. But a belt grinder is far more practical for most uses.

I'm a retired firefighter, and we did a fair amount of axe sharpening on the job. We always used a file to sharpen our axes, never a bench grinder. You'd get a good chewing out if you were caught sharpening an axe with a high speed wheel. We didn't want to ruin the temper of the blade with too much heat. It takes longer with a file but there's less chance of screwing things up. I still sharpen my axes and mauls at home with a file. My two cents.
