I Plan on doing a follow up showing the cooling effect these fans provide with an Infrared thermometer coming soon! Cheers ~Duke

Nice set-up, thanks for sharing the photos of your rig and your results!
Same fans I'm using, had 'em left over from a project years ago. I used the thermocouple so I could set it up to run constantly, in view of a web camera. The power strip that runs the tumblers is on an iHome WiFi controlled outlet. Net result is that I can view the tumblers anytime from anywhere in my phone, and secure power to the whole rig remotely as well. I am sure there are those here that would say that all of the time, effort and money would be better spent on grit, tumblers and rough. True that, but I only spent about $40 on what I set up, as I already had most of the gear on hand.
Everyone has their own threshold for piece-of-mind. After we smoked the old Lortone (which did not shut down when it overheated), there was a group decision that some extra safety measures must be implemented. My wife is a lovely person, and very accommodating with my hobbies, but if I burn down the house tumbling stones, I suspect I might well not be included in whatever follow-on living arrangement came after the casualty. We old submariners tend to fail safe......

zekester55 I made the original post some time back in September 2017 most thought I was Nutts. Being in the HVAC field since 1977 and a Licensed HVAC Contractor since 1982 I think it gives me the the authority to speak on these matters. Just because a motor is thermally protected does not mean it is good for a motor to reach these temperatures. The varnish that coat the winding's will break down if the motor is running hot and the bearings or bushings whatever the motor has the lubrication will dry up and wear will occur more quickly when it runs hot. This being learned from the 100's hundreds of motors that I have replaced of all sizes. If these tumblers are getting hot it is most likely that the motor that was put on it during manufacturing wasn't large enough in the first place and it is running at its maximum duty. It doesn't take a genius to figure that one out. Do you expect the MFG to spend extra $$$ to make a good product by putting in a larger motor or one that will sell if they cut a few corners? When I put together my new shop I wired in three fans to cool the 6 tumblers I have. As you said everyone has a comfort level and the way I figure an ounce of prevention is worth a pound of cure. ~Duke

Definitely agree on keeping motors and other equipment reasonably cool. I have way too big of a fan on the motor I'm running but the thing will burn your hand without it. Working around electric motors in oil and gas we see heat as a major issue with the things you mentioned. Bearing grease being the number one.

On the Lortones, I see some of the pictures with them sitting on towels or other cloth materials. Anything that you put under them like that will restrict some of the airflow and also hold more heat. I work for a PC manufacturer, and see this a lot.
I had some leftover scraps of 3/8" rubber flooring that I put in my exercise room that I put under mine. They are durable and easy to wash off as needed. I also got a whole bunch of cork flooring samples that are interlocking, those would also be pretty good.
The cooling fans are not a bad idea, and many of them come with heat sensors that will trigger when they hit a certain temperature. I think they might be more-effective if they were built into some sort of shroud so that you can control the airflow more.

Here's my low budget cooling from parts laying around. Computer chassis fan glue gunned to cardboard powered by a 12v wall wart...does the job as they're only warm now as opposed to pretty hot before...my only (mild)concern is how much dust etc is getting blown into the motors.

Runs hot to the touch year after year after year, don't care.

Blow em out every so often or move them to an enclosed cleaner location.

There's a compressor 5 ft away so it's handy for blowing them out when they're looking needy. I have a Lortone 3A as well (in the darker right side of the photo) but it doesn't run as hot as the Thumlers in the photo. I took the Lortone's cover off when I was replacing belt after belt till I figured out the pulleys were out of alignment...since then I've left the cover off for better oiling/cleaning access and it seems to run cooler as well. All this is in my unfinished basement so noise and dirt aren't that big of a deal to this single, hard of hearing bachelor

Well done on your projects. I noticed there were two types of the AC fans...low and high speed. Does it matter as long as the air circulates around the motors? I plan on placing the fan between my two Lortone QT66 tumblers (to conserve space I placed both 180 degrees to each other - side to side - having the motors align. The fan will go in the space between the two motors). Good idea or bad idea??? Glenn

I took the cover off my 3A and put a fan on it runs a lot cooler.

Glenn Thanks gmitch067 Glenn I would take a thermometer and see what the air temp is between those to units maybe hook them up in a trial run and see if that cools them down enough. As you can see on my fans I elected to draw air that is away from any source of heat. And I like the higher speed fans because this is in the garage away from the house so sound is not an Issue. Ole Duke can tell ya one thing but the proof is always in the pudding. You would think that #1 fan in the picture above would pick up some heat off of #3 Fan off the two Lortones but it doesn't. I ran everything on a mocked up trial basis before I went permanent install. AS glenr1975 mentioned removing a cover may be an option as long as there is no little fingers roaming around. There are fundamentals to follow when using fans you try to use as cool of intake air as possible to cool the object you are cooling but in the end trial and error with some decent instrumentation for temperature recording/reading is the best test. ~Duke

The lortone and the thumlers are designed to run Hot to the touch. If you feel yours gets Very hot?. the problem my be dust or dirt Getting sucked in and left to mix with The oil lube. this will get the motor slugish or a slow start until it warms up. A easy fix s to remove the motor and soak it in Mineral sprits overnight. in the morning Remove and shake out the excess and let air dry. Once dry Re oil lightly. Remember do not plug in while in the mineral sprits. Sal

It was designed improperly with the incorrect size motor installed in it. wether it is the load or gearing or both the motor should not get hot. My equipment is clean and they ran that way out of the box. As a 40 Year HVAC Mechanic I have changed 100's of motors of all types and heat is a motors worst enemy. just because they run HOT doesn't make it right. ~Duke
