Been saving since I made my first knife about 8mo ago for a "real grinder" ;)
I must say i am very pleased with the Coote. It is set up with step pulleys for 4100FPM, 2300FPM and 950FPM. Tracking is great and no vibration.
It took two weekends to build a new table, mount everything and install a glass platen. My shop is only 10'x10' ,so the table is on lockable, swivel casters.

If you look close, my frist" Coote knife" is on the work rest. It only took a third of my previous grinding time.
 
Lookin good :cool: I've got a Coote too, its a heck of a nice machine. Makes me wonder how I ever got by without a belt grinder before :eek:

Just out of curiosity....why did you go with that pulley set up? I've got the step pulleys mounted right on my grinder and motor. Just wondering if the mandrel in the middle makes something work better?
 
Matt, if I had to guess, it gets the pulley away from the machine and allows a lot easier rotation into different positions. The biggest problem I've had with my Coote is getting it set up so that the belt is straight and yet the motor pulley still clears the column when I rock it back to access the contact wheel. I still haven't gotten it right after moving it twice and it's a hige PITA, so for now I can only rock my machine back about 15 degrees. :grumpy: It's a cool setup, Cooter!
 
Matt,
I ordered the Coote with the 6" wheel, cheaper and I don't do hollow grinds. The diameter of the step pulleys available was almost the same as the drive wheel and with the 3450 RPM motor I had would have over sped the grinder by about15%. So for safety, I put a 2" and 3" pulley in the system. It also gives a slight apparent horse power increase. The motor is mounted on a 6" heavy duty butt hinge and the weight of the motor provides belt tension. Changing speeds is a breeze.
I plan on adding a reversing switch to my single phase motor.
 
I've got a 10" wheel and haven't had any problems with the pulley being in the way. Had the same issue on the 3450 rpm motor, but I broke down and bought a new one thats 1725, as the motor I had wasn't really fit for a grinder anyway.

How far back are you wantint to tip the grinder Chiro?
I've got mine tilted back just a little bit, and 99% of my grinding is hollow grinds. I guess I do have freakishly long arms though. With the wheel height set so that my elbows are bent 90 degrees, I'm standing far enough back still that the work table on the platen doesn't block my view. I also keep the knife around or slightly below the center line of the wheel.
