IMG (for forums, boards) This is my tumbler that needs a motor replaced. I am hoping for some advice on this as I am a newbie.The current motor is a GE 1/8 HP 1725 rpm. Thanks

I guess I also need help posting a photo. I just got photo bucket and uploaded a couple pictures of the tumbler, then I copied and pasted the Url I thought.

I'll wait for those that have been there done that to answer your questions, but my comment would be that you can find a motor local to you for a whole lot less than that one on eBay totaling $75 w/ shipping.

Go with the $75. IF it is an exact fit to the motor frame you have. You can find a used motor 'some where' cheaper no doubt. But to find the exact same motor that will sit in that particular frame is going to be a long shot. That is a dandy tumbler. I think the green brackets can be slid wider or narrower to accept many sizes of motor frames That looks like a 48 frame, but not sure. Ah-Surplus Center has a dandy motor( Intheswamp) for $39.95: I would put this 48 frame motor on it and wire it for 1/18 HP/1140 Rpm and put a 1725/1140=1.5X bigger motor pulley(sheave) This 1/18 HP should spin that 12 ?? pound barrel with ease and save money on power at only 1.9 amps. Your 1/8HP is probably about 3 amps. Marathon top of the line. Or you can wire it for 1/6 HP @ 1725 RPM and not change the pulley for the same speed, but pull a bit more amps than your 1/8. www.surpluscenter.com/Electrical/AC-Motors/AC-Motors-Base-Mount/1-6-1-18-HP-1725-1140-RPM-115-VAC-MARATHON-MOTOR-10-2894.axdEd, this motor could probably be wired with a 2 speed switch to go 1125 or 1725. without pulley change. This is the hard to find 110VAC bullet proof HVAC motors I use. With frame and capacitor. El perfecto. @petrified- I would get longer wood base and move the frame out for 2 barrels. Looks like you have several inches of extra shaft on the right side. Wire the above motor for 1/6 HP and have plenty of power to spin two 12/15 pound barrels. That's about the finest tumbler layout. Tempts me to buy out 117 of those Surplus Center motors and(copy) make those end supports-go into 2 speed tumbler biz. 1725 RPM for coarse, flip a switch and do 1125 RPM for finish grinds.

I don't see end rollers ??
Those 48 frames and motors about always have rubber bushings at motor-very quiet.

That's a dandy looking' tumbler! Similar in layout to my home built but the frame is much nicer. I like the way the motor mount allow for adjustment of belt tension.

One of the few that are expandable in length too. Oops, are rubber coated shafts ? Or stepped down in diameter ? Did not see that at first petrifried

That motor looks pretty good, Jim. I might have to try one and put my other one in "reserve" for the time being. It would make mounting way easier. The 3.4amps kicks the electricity bill up a bit more than I wanted but it does give you the option of flipping a switch for a higher speed tumble. The 1.9amp slower speed is nice though, and the tumble can be sped up with pulleys. I'll look at this one hard today. Thanks for pointing this one out... I wonder, did I just miss it when I was searching or do you think they just got stock on it?...just curious.

Just received that SC catalog Ed. must be a recent buy out.
That motor from a motor house is $116-$143. those are industrial grade Has every option except thermal overload. they will sell out quick. SC rarely has 1/8 and 1/6-1/15 with 1/2 shafts

SC rarely has 1/8 and 1/6-1/15 with 1/2 shafts Already got one coming! Added a 4" motor pulley to the order, too. I started to go ahead and order some 1/2" pillow bearing (almost twenty dollar cheaper for 1/2" shaft vs. 3/4" shafts) and set up a 4" barrel roller pair. Decided to just build the tumbler with extra space to add the rollers for the smaller barrels at a later time...budget is shot. ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) Thanks for bringing attention to this motor, it's appears to be perfect fit for a tumbler. I'll probably just wire it up for 1140rpm, though adding a switch in "just in case" would be an easy mod. At 1140rpm and with the motor pulleys and the 9" jack(?) pulley (the roller pulley) that I have, I should be able to get roughly 26, 39, and 52 rpms...and at a lower electricity co$t. Provided, of course, that the lower hp rating won't be in a hard strain, which I don't think it will be. Great deal for someone looking for a tumbler motor...trust me, I've looked at *lots* of them!!!!!!!!!!!!!! Thanks again, Jim. Ed

petrified, where the motor platform mounts onto the lower rod of the frame, does the motor platform swivel up and down and the weight of the motor keeps tension on the belt? Or, is it a rigid attachment with no movement? Nice looking tumbler!!!

Nice looking tumbler. Does anyone know what sort of hp/A motor you need to run those 12lb barrels (or 1,2,3,4) of them?
I have a few older induction motors around, most are several amps 1/4-1hp, which isn't really a cost issue for most things that are run occasionally, but running a tumbler 24/7 seems like it's worth paying attention to. My old scott murray has a 1/4 hp 5A! motor on it which seems like overkill and expensive. I have 4 of these 12lb barrels with a one barrel tumbler, and a three barrel tumbler... Maybe I should just find smaller barrels, that's a lot of material to keep running.
Anyone know what motors Lortone or thumblers put in the current 12-15lb tumblers?

I have a 1/8 HP similar to the one in this thread that runs a 40-50 pound barrel at 28 RPM for years using same single pulley system. They make cheaper 1/8 HP's, that would not last or even turn it. pays to buy a good high grade motor. Pays off in electric savings too.

Thanks everyone!
Jamesp- The shafts do have a rubber coating on them. what are end rollers? I think I'm going to order one of those 1725/1140 marathon motors! My current pulleys measure 9 inches and 1.5inches. I like the idea of wiring a switch to flip between speeds if i can figure out how to do that:/ Should I order a larger motor pulley maybe a 4 inch?
The green motor platform does slide narrower or wider to accommodate for different sized motor mounts and if you tighten it down really good is fixed and rigid.
So the theory is grind at 1725 rpms and polish at 1140 rpms by flipping a switch and not changing out pulleys? I still haven't made it past the coarse grind step yet:/

End rollers so the barrel does not rub on the shaft bearings.
The amps I quoted are loaded amps. 3.4/1.9, it will not pull near that when running unless you really load it up or you got bad bearings.

I do have end rollers, thanks for clarifying. I'm going to order that 1725/1140 marathon motor today! I'm a little confused on the pulley situation, could someone help me with figuring out what pulley to order with it?
