Topic tags/keywords: homemade bandsaw motor

I recently finished building Matthias Wandel’s 16” bandsaw. I’ve been using it some with an underpowered washing machine motor, and I’m ready to put a better motor on. But I don’t want to spend $150+ on a motor. Can anyone point me to a motor for less money? Needs to be AT LEAST 1/2 hp…more if possible. 115V, single phase… 1725 rpm preferred. I’ve been watching Craigslist for some power tool with a motor, but nothing has come up for less than I can can buy a new motor for. Also, is there a reason NOT to use a swamp cooler motor? They are cheap but I don’t often see diy toolmakers using them. Thanks! —Jer

You can use a 3450 rpm motor on it simply by putting a larger pulley on the driven wheel, and a small one on the motor. And doing so has the advantage of increasing your available power.

EBay is a good source for old motors. You may need to replace bearings, but other than that not a lot to go wrong on a motor. Shipping usually costs 40 to 60 dollars for a motor. So finding one you can do a local pickup on will be important. No idea what a swamp cooler motor is.

You can sometimes find cheap motors on craigslist also.

I wonder how well a variable speed treadmill motor would work?

For mine I got a cheap 3 phase motor from CL and a new 115V input VFD
That is >$150 but gives variable speed.

I would consider finding an old treadmill. They pop up on CList in my area all the time for $20-$50, and most have 2+ HP motors.

Funny you mention that…I happen to have a three phase motor just laying around, and I was thinking of doing that! But it’s a 440v…and I haven’t found a VFD that goes 110-440.

Harbor Freight has a 1/2hp 1800 rpm motor for around $100. You can easily find 20% discount coupons and get it for less.

Not sure but I think some/all motors can be rewired 440 to 220.
You might check for a schematic inside the connection box.

I have a 3/4 HP ,1825 RPM, motor you can have if you live close enough to Houston to pick it up. The shipping would be more than a new motor. It is American made BTW

I’m in AZ…so probably won’t be picking it up. Thanks anyway!

Have you checked the classified ads for old table saws? More often than not in my area, I see old beat up table saws with +/-1hp motors. Then you just do what runswithscissors said. I got a 1-3/4hp Walker-Turner for free with an old jointer because the guy was moving and didn’t want to take it. Keep your eyes out. EDIT I clearly missed the part where you said you purchased one. New works too!

I’ve been thinking about making a Wandelsaw for a little while and I don’t know if I want to make his 14” with increased cut capacity or the 16”. What made you go with the 16”?

The HF motor has worked out well. It has a very fast start, and it normally slips the belt just a tiny bit on startup. Other than that it is great.
As for what made me choose the 16”... Really nothing but the extra 2”. I had no intention of using it as a sawmill, so I didn’t see any real advantage to the 14”. The 14” may be slightly easier to build, but I thought I could handle it and I was rewarded by a slightly larger machine…

Very cool. What was the material cost, if you don’t mind me asking?
