Where do you folks find your small motors like the Daytons for DIY tumbling operations. Ebay is crazy expensive but maybe that is the going price? If anybody has a few laying around, let me know. I've got stuff to trade and cash to pay.
Thanks,
Scott

How small? I got a 1/3 HP motor from a furnace repairman. I called at least five places before I found a guy who would sell me one. It cost $20 and works great. One guy sold his motors to a motor repair shop, one said they were impossible to remove without breaking them, one said he didn't have any at the time, and another wanted too much money.
I just went to the basement and looked at my power vented water heater. It has a 1/10 HP motor on the vent. I'm sure the one that broke a couple years ago would have had the same size motor on it. The motor would have been fine, it was the water tank that failed.

Rob,
That is what I am finding too. Nobody has any used motors!

I thought it was you who suggested going to a metal recycling place in an old thread. I called our local metal recycler and was told that they don't sell motors because they can't be sure they work. I was almost ready to buy a used motor from a motor repair place when I found the one I bought. I think he wanted $50 for a 1/2 or 1/3 HP motor.

Yes I get all of my larger motors from two different scrap shops. They both sell them to me at scrap prices. If they don't work, I just scratch a huge "x" on them and bring them back. The smaller ones are tough for me to find.

depends upon how small. Try your local heating and air conditioning guys. They get a lot of 1/4 HP motors when they replace swamp coolers or other fans and such.
or of course, surplus center works for specialty stuff.

Continuous duty and thermally protected, perfect for a tumbler.

not sure what size tumbler would be max for 1/6 hp but I like the low amp draw for some electricity savings. If I had not blown my whole rock budget already I would order than one for sure.

I have a 1/8 HP on a 16 pound tumbler barrel turning 25 rpm(a little fast).It is a special motor in that it has higher torque because it is a 1000 rpm motor.Has been on that old tumbler for many years. Coomercial AC units are being scraped commonly at scrap yards and they often have fans operating off the control voltage of 110 VAC.Most of these motors are 725 and 1040 RPM.Allowing single reduction on a tumbler.
Make sure they are not 277or 208 voltage.They will have a fan blade directly mounted to the motor shaft.

Most HVAC shops aren't going to want to take the time to deal with this. They are making way too much $ elsewhere not to mention the techs are making $20-35hr which is too much to be playing around with $20 used motors. If you had a friend in the business that would be different.

If you had a friend in the business that would be different. You must be in Texas where everybody seems to be busy!! Here in SoCal if the outfit is large enough to have an office with someone in there during business hours then they are quite pleased to make some beer money from scrap motors.Every little bit counts. Nothing ventured nothing gains. I am out of cliches, until later, I must sign off. |

What kind of motors are suitable for use with saws? Do they need to be enclosed? Would a motor with different speeds work?
Later,

Jeri, a lot depends on the size of saw. If the motor sets where it doesn't get hit by spray from the saw, an open motor will be OK. But if it does get hit by spray, use an enclosed motor. You'll want a 1725 RPM motor. One with a capacitor start and thermal overload circuits is best, but I've used salvaged washing machine motors on 10" and smaller saws with no problems.

Just a couple more thoughts... Have you tried swap meets or second hand (thrift) stores? We've picked up small motors for $5 or less. While they might not always work, my thinking is that if the person knows it doesn't work, why would they bother trying to sell it? Anyways, for $5 it's worth taking a risk on. Don't think we've got a non-worker yet. Jean

For tumblers all you need is continuous duty. Try yard sales, farm auctions, flea markets, neighbors. Always make sure your motors are grounded.

Washing machines and dryers have decent motors.Most of them get trashed for other reasons than motor failure.So you might btry an appliance repair shop.
