I’ve been looking at stubby nubs plans for a wide belt sander. I want to try one on for size.

The other day I was splitting firewood and needed to cut one down to size. Rather start a chainsaw I grabbed one of my electric chain saws. I soon found that both chains were dull and I don’t plan to sharpen them or replace them.

That night I had an epiphany, what about using the motors from the chain saw to turn a sanding drum?

They turn slow enough I think.

Any thoughts?

Interesting idea. I have an electric chainsaw but no idea what kind of motor is in it, quiet though.

treadmill motors are also popular for this, since they can be configured for variable speed. It’s also popular to get a 3 phase motor (they’re CHEAP on craigslist) and attach a variable frequency drive (VFD) to it for variable speed, as well.

A chainsaw motor is not designed for continuous duty. I think it would fail. Why would you NOT sharpen your chains? A chainsaw hand file is about $5. The Harbor Freight electric sharpener is about $30 with a coupon and does a great job. If you don’t want/need the saws anymore sell them and buy a belt sander.

I don’t care why he doesn’t want to sharpen them. They’re his chainsaws. He can throw ‘em down a well for all I care. The issue is power and whether it has enough.

I have a 1/3 hp servo motor and control available!
I is variable speed, bidirectional, speed up/down ramp programmable, and external inputs for other control options.
The shafts is metric as the motor is Siemens.

PM if you are interested!

“He can throw ‘em down a well for all I care.”

Two electric chainsaws ‘down a well’ is probably a good down payment on a drum sander – that’s why I asked the question. Used motors made for continuous duty are a dime a dozen. If he doesn’t need the chainsaws he could sell them and buy a motor made for the job. Or trash the chainsaw motors by building a tool that they weren’t made for. I don’t care either.

Steveoom, it just a motor that has some options.
These options are programmable as opposed to changing belts and/or pulleys.
