I have a video that the late Bob Ogg made with him making a folder
his shop was not much in the way of high tech but he made a knife come alive he used stones and a long shaft with felt wheel with compound
on them that dries hard and he also used them for some removal
his blade and fit amd finish was great.I think useing stones and
the hard felt wheels with the grinding compound on them would be the way to go and save alot on the bill on belts.
I would like some input to see if any one else does it this way knives.

I made my first 5-10 knives, including a 4 foot double edged broad sword with a rock stuck on an old table saw. I saw Bob's video too and it got me to thinking about buying a 2" thick by atleast 10" diameter coarse rock to put on my buffer for rough grinding. I don't see any reason why you could work thru a couple grits of stone and then buffing compounds like Bob did for years. Just buy the best face shield and hard hat you can find.
 
I've been on the look out for an old grind stone, 24-30 inches. I 'm thinking to run it slow, (aprox 30 rpm) and in a water bath. Now to have several sizes and grits, that I think would be the cat,s meow.

I was going to start a thread earlyer, and ask If any one had any thoughts on the subject.

The only problem I can see is the dust, unless you run them wet, which leaves you with some engeneering problems, but also advantages.

I have thought the same thing,I was thinking about that
I think it could be done run a water mist from the side and have a
rig set up that is belt driven and have a splash guard in front of
the motor that way you would not have to worry about water near your motor,Mr Ogg in his video ground 3/32 stock on his ten inch stone
and after he rough ground the blade bevel he went to the felt wheel
with different grit compound on it the blade had a great looking
lines and finish,I think there is alot of ways of doing it,
he ground on the top off his wheel.Another way to keep the blade from heating up is take a peace of Key stock which is very heavy,and mount your blade on it,that way the heat will transfer to the block,you may be able to get away with it and just grind like you do now.

I have the grinder you are talking about. The stone is 24" dia. has a 1/2 hp motor and a huge pulley at the stone so it runs very slow. The stone runs in a water tray which keeps it wet and no dust. The trouble is the stone is too fine for grinding. I think it would sharpen blades but I have never used it for that. I should try dressing the stone before abandoning it forever. Come on over to my place and see it, I may just give it to you.
 
A local maker that makes knives for the blackpowder clubs uses nothing but grinding stones. He cuts old saw mill blades to shape with a skil saw and metal cutting blade, then grinds with 3 different grit stones. He made his belt driven and geared real slow with the wheels sitting in a wash tub of water, he doesn't buff them but he can grind a blade to shape in no time. He says it stays cool enough that he doesn't take the temper out of the steel so he doesn't have to heat treat. Makes a pretty good knife in about 2- 2 1/2 hours, finished with handle.

Good Luck
Bill
