View attachment 650118

do you find knife sharpeners an issue sometimes..

well, not anymore.

fits in my dining area just fine. (dining area, ya, not really.)

i've been thinking about how i was gonna sharpen the Bowie that i have not bought yet(kidding), as there are a lot of talented makers..

now i just need someone to stand here and crank this 17 inch diameter wheel.

regarding the stones grit , i'd sat it is more of a high grit than a medium. and it is mostly flat. not perfect, i can tell it was bowled at one time.

someone has made a sincere effort to dress it. seems to work real smoothly.

for anyone w/ experience on one of these, what recommendations might you have?? .. thanks in advance ..

PS i've been a member almost two years and this is finally the first photo i have posted. Gold only a week however. still, now i have found one way to do it. thanks BF

Nice! I love seeing things like that. My neighbor used to have one similar to that one in his garage.

Recommendations? I'd use the thing. Rig up a foot pedal, get some cheap bar stock and go to town.

Put a gear and connect a weed wacker engine to it

That's cool.

Where might one get one of those ancient stones?

I have one and it is fairly badly out of round. I have no idea how it could get out of round but there it is. Any ideas on how to dress it back round? I've made some progress with a 4" grinder. Burned up a few 4" wheels. I think it would be cool to have it going to sharpen on.

Neat. Large rodent on a big @ss hamster wheel ?

If it's the old, fairly soft sandstone variety you can buy a diamond dressing bar to bring it back to round. Keep the bar fixed and spin the wheel. Works a lot like a lathe. Grind away the high spots and keep working inward until it's at 360 degrees of contact.

I wouldn't use a motor on an old stone wheel. You want to keep it at a low rpm. If there's any fine cracks that you can't see, you certainly don't want a 20-50lb wheel coming apart at 3000rpm.

T.L.E. Sharp nailed it. Those big old natural sandstone wheels should never be turned faster than you can move them by hand or foot, 100 rpm or so maximum, plus or minus depending a bit on the diameter. Back in the day they turned them a bit faster in the knife factories with water power, but being killed by an exploding wheel was one of the many occupational hazards of being a cutler.

Also, at low RPM being perfectly round is not as much of an issue, you can follow the slowly moving stone with the knife
