Before you ask, yes, this rig is only to be used at low rpm. If I dial the rpm up to high the belt will indeed reach out and slap me upside-the-head. Ask me how I know this.

And here's another one I have:

This pic was taken just after sharpening the knork. in front of the knork you'll see a little Wharncliffe utility knife I've cut out but haven't profiled yet and also a couple of marking knives to use in the wood shop. I decided to make the Wharncliffe utility to see if I like a Wharncliffe as much as I like a sheepsfoot. I suspect I'll like the Wharncliffe even more.

And here's the 6"x48" Powermatic, wonderful machine but the only thing I've been able to do with it as far as knifemaking is concerned is a little profiling and surfacing bar stock.

Here's mine. I used to use a crapman 2x42", but I gave it to my father for wood work several years ago.

First machine was a Coote, and probably the best bang for the buck out there.

Finaly got my hands on a KMG, and lord what a grinder.

Horizontal edge grinder

and my buffer. 1/4" horse motor and pillow block bearings.

Disk sander, gets used more than any other machine, got it from TrueGrit a several years ago, added my own motor.

Here's one of my 2 (not counting the requisite bench grinder) This is a home made 4x106" wet belt grinder. It will swivel from vertical to horizontal. It uses a belt drive with 2:1 reduction from a 3/4hp 1750rpm 110v motor. the water is dripped through a petcock on to a kitchen sponge which wets the belt as it expands. It has a 6" platten if I want to buy those wider belts but it will track to either side with ease.

And this is my main grinder. It is another 3/4hp 1750rpm 110v motor 24" wooden wheel grinder with a taper pin lock. I use Shop Roll Abrasive from Klingspor (J flex Belting) I have it set up to run at a fixed 2200 SFPM. which is great for steel but tends to burn wood. my father and I made the whole thing using discarded Angle Iron and I bought a sheet of 1/2" hardwood plywood and cut out 4 24" squares, then glued and screwed the planks together. found center, drilled for and installed the arbor and then cut out the circles and trued the wheel on it own arbor. the motor turn 1750 rpm running a 5:1 reduction through pulley's and ends with a wheel speed of 355 rpm. Please excuse the dirty floor. It's getting cleaned thoroughly this weekend.

Jason,

The big 24 inch wheel is really nice. I'd like to try it out. I figure, with that much mass once it gets moving it wants to stay moving. Thanks for sharing your grinder set up.

Thanks Fred. It's nice and smooth and I dont have a whole lot of bump at the belt split but there is a little. the pillow block bearings and drill rod arbor make things nice. The weight really isnt that much. the frame is a heavy dude though lol. The wheel may only weigh at best 10 pounds. so not a whole lot of mass. I am thinking of making a double grinder out of a truck rearend on a double A frame pedestal though. with double 18" wheel and run real 2x 72 belts. If I do start that project I'll post a WIP

Keep us posted I for one would like to see the combination grinder set up.

Hello everyone, pls find this photobucket link to my Michael Morris (www.michaelmorrisknives.com) version for a grinder.
This grinder was built with Michael's help. He is a very modest and kind person, helped me a lot. A real gentleman, Never met a person who was so happy to help.
I'm trying it out these days and I'm very happy with it. Please feel free to ask anything, or if photos are needed.
All credit to Mr. Morris, and again a big thank you to him.

Nice weekend to everyone.

This is one made by Rick Menefee that I am using now. 18 inch wooden wheel takes 72 inch belts and tracks perfectly.

well here is my home built grinder, mostly stuff I pulled from the scrap pile, motor was a freebie, total cost $200, all I had to buy was the contact wheel, tension/tracking wheel and the pillow block bearings, I also have a couple of different tool rests, and a piece that bolts to the platen and holds the knife at 23 degrees for sharpening

The motor is 110V 1/2 hp 3450 rpm with a 2 inch pulley, the slave pulley is 6" the drive wheel is a 6" cast iron caster, which gives me a belt speed of 1806 FPM, and because my tracking wheel is using 2 axis, caster and camber, the tracking is very stable, I can push sideways on the slack area hard enough that the belt will cut a radius in the steel I am working on

some day I plan to move the motor and slave pulley over to the center and add an 8" disk sander to the end of the drive shaft, that should make profiling a snap

with donated parts from every thing imaginable the boys and I like to call her Frankingrinder LOL
