Does anyone have any pictures of their Coote set-ups? I just bought a used Coote grinder and am now faced with what motor to get and how to set it up. Thanks!

...that was before I cut out a hole under/in front of the wheel for the sparks to be thrown down into a bucket. I have a 1 hp TEFC motor on it, and it runs pretty smoothly. I just keep it on the slowest pulley setting.
 
I run both my grinders off of one dual-output DC motor controlled by a salvaged treadmill unit. The on/off and rheostat are mounted on the bench between the machines and the actual circuit-board is in the gray box mounted on the wall. The Coote is mounted on a sliding bar that locks down with a t-screw. This lets me properly tension the belt and keeps me from hitting the bench with sparks. It also lets me slide the whole grinder out of the way.

Nothing special here... If I was going to do it over, I would bring the grinder nearly to the edge of the table. I need to take the rest at the wheel off... I've never used it. The motor is on a hinged plate so I can change speeds quickly.

Thanks Mark and Mark! Keep 'em coming if you have a pic handy of your set up. Is anyone using a variable speed set up? Variable speed or not, what HP motor should I be looking for and where is the best place to buy?
 
My coote setup looks almost identical to Mark's 'cept the board my motor is mounted and hinged on is further back using a longer belt, and is kept tensioned with a spring behind it.
 
Tcurve, here are photos of my Coote setup. I used a variable speed pulley setup. The stand is made from pipe, it has a wrap of aluminum sheet, and a plywood and laminate top. The speed control crank goes up through the top and can change the speed from about 1500sfpm to about 5600sfpm. I also wired up a reversing switch to give more flexibility. I got the disc setup for it as well. In one photo you can see the water trap I added when I built a dust extraction system. One photo is the variable pulley setup.

Have fun!

This is my setup. I have the motor mounted underneath and to change speeds I just lift the motor table and slide the belt to the pulley I want (3 step pulley). I also have the small wheel attachment as shown, and the knife rest. It is an 8" wheel (I have a smooth and a serrated). It is wired for 220 volts. It works well for me, but I am still cutting my teeth as a knifemaker.

Alden, would you mind going into further detail about your dust collection setup - specifically the spark arresting system you use?

Thanks!
 
Matthew, I posted some photos of my spark trap here.

The blower is a furnace fan which is housed in a roof soffit "outside" of the shop to cut down on noise. The trap seems to work well, as there is quite a bit of debris in the bottom whenever I clean it.
If I haven't explained the setup well enough ask me and I will attempt to give a better description.
I could find little info when I put this together, but maybe someone has a different spin on how they do it.
I do know that you do not want a "hookah" type setup where all the air has to go through the water. That exponentially increases the requirements for the fan.
I hope this helps.
Thanks for your interest.

Excuse the mess.:o Stepped pulleys from Norm Coote and 10" wheel. 2 HP TEFC 220V motor.
 
Wow great to see some cootes. I have mine built on a stand like Milt has his.
Except I have the motor mountd on a pipe which lets me move the motoer back and fort to change speed easily, as well sets the tension on the belt.
I also think with the motor doen below it can be easier shielded from the metal dust getting inot the motor magnets.
Cheers Ron.
