I've been thinking about building a honing rig for honing blocks. My Sunnen cylinder hone works just fine, but it kills a 3/4hp drill in short order. I drew up a nice rig using a 1hp industrial motor

I'll be using stepped pulleys to drop the speed down anyway, but the speed control needs to be 'live'. I don't need a whole lot of range with the speed control, but you have to adjust the speed a bi

It gets worse. You also need a DC motor that will run about $400 for 1hp. The prices in Grainger's are, unfortunately, hard to beat. The modern speed controls work very well - speed is practically co

How is it I can buy a 3/4hp variable speed drill for $75? I know the power is overrated and the service factor stinks, but I don't understand what makes one type of application cost so much more tha

Are you familiar with the variable pulley like used on ShopSmith machines? The front panel knob moves the pully sides apart and together, changing speed. Perhaps you can find a used head or just orde

Look for an old Dutch car called the DAF that used this variable pulley in its drive train instead of a gearbox! Later, Bob == Robert A.C. Hamilton, P.O. Box 202, Waverley, Nova Scotia, B0N 2S0 Home

Sounds like a snowmobile's centrifugal clutch, but if so the pulley ratios change as the engine speed changes, so back to square one, how to vary the engine speed. Jim Wallace Listers, Look for an ol

What about the "variable diameter" pulley setups? I'm not sure how they're packaged/mounted for generic applications, but I've seen them as part of the drive mechanism for lawn mowers and go-carts.

FWIW, the DAF Daffodil used 2 belts, one for each rear axle. They used a variable pulley system to control the drive ratio. It was called the "Variomatic". Very smooth and very slow. The DAF had only
