Wheels and tensioners
Drive wheels, platen wheels and tension knobs.
The parts that decide how the belt runs, and the parts that go missing. Drive wheel diameter sets your belt speed, the rubber platen wheels keep the belt from chattering, and the knobs are the ones that roll off the bench and under the toolbox.

Love the tracking system and the ratchet belt tensioning - makes changing belts quick and painless. All the controls just make sense.…

Got this belt grinder for our farm shop and it's been awesome. The machining quality really impressed me - everything fits tight and feels solid, you can tell they put real care into making it.
Setup took maybe 20 minutes tops and it was ready to roll. Runs super smooth and quiet with basically no vibration. Even though it's aluminum, there's zero flex or rattling - feels rock solid even when you're really putting it to work.
Love the tracking system and the ratchet belt tensioning - makes changing belts quick and painless. All the controls just make sense.
But honestly, what made this purchase special was dealing with Rich. He was incredible - answered all my questions before I bought it, made sure I got the right setup, and followed up several times after it arrived to check how everything was running. You just don't get that kind of service anymore.
First belt grinder we've owned and I'm really happy with it. Thing's built to last and performs great. Would definitely recommend it if you're looking for a solid grinder for your shop.
Keep up the fantastic work Rich!
What matters here
Why it is built this way
Speed is the wheel
Swapping a 4-inch drive wheel for a 7-inch is the cheapest way to change belt speed on a fixed-RPM motor.Keyed 5/8-inch bore
Machined for a standard 56C motor shaft, so it lands square and stays put under load.Keep spares
A $39 set of knobs on the shelf means a lost knob costs you a minute, not an evening.
Same motor, two belt speeds
Each turn pulls pi times the wheel's diameter of belt past the platen, so at the same RPM the 7-inch wheel runs the belt 1.75 times as fast as the 4-inch.
Where the wheels run
One 2x72 belt runs over four wheels: the drive wheel, the tracking wheel on the stainless ratchet tensioner and the two platen wheels.
Questions
Before you order
4-inch or 7-inch drive wheel?
The 4-inch runs the belt slower with more torque, which is what you want for sharpening, finishing and tough steels, and it is what ships on every Torus. The 7-inch spins the belt about 75% faster for quick stock removal on big work.
How many rubber platen wheels do I need?
They are sold individually and a full flat platen assembly uses two. If you are replacing a worn pair, order two.

Order the spare before you need it.
Wear parts are cheap and small. Losing a grinding session to one is not.
