I live in the Kootenai Forest Montana. Mother Nature is already doing a fine job of burning the half the state up this summer. Around here we bless everyday our homes are still standing and keep a bag packed at the back door. I'd prefer not to beat Nature to the punch. Are tumblers safe to leave to run for long periods of time when no one is around?

The motors on most tumblers get pretty warm . Are they safe to run on combustable materials ? Probably , but I have mine sitting on a concrete floor just to be safe . Rotaries generally run for a week at a time between cleanouts so are made to handle it .

Walker know the feeling neighbor from the east shore of Flathead helicopter bucket brigades are continually passing over my property smoke is so thick I only go out if necessary. One suggestion i would make is to have your tumbler on cement and on a CFGI outlet.

from Tennessee! Sorry to hear about the fires. Normally our summers are very humid with afternoon showers so everything says damp, but last summer was record heat and drought and we had a bad time with fires. I can relate to the fear of something so massive that you have no control over. As far as tumblers go, I'm careful of what is around my tumblers, but yes, they run 24/7 and between work and school, the house is empty most days. If we are going out of town for more than a day or two, I will turn them off. I've traveled out west a few times, but have not gotten all the way to Montana. But it is on my list of someplace to hound someday. Please show us some pictures of your finds. We love pictures here!

Properly maintained and with a thermally protected motor all should be well.

I just recently got the bright idea to hunt rocks so I'm not much of a resource for good spots but maybe by the time you make it I'll be better clued in.

Walker if you do not have a gfi outlet near by the do sell power strips with built in circuit breakers,I would recommend one of them for your tumnler,just a precaution,goodday.

there is this one www.flatheadguide.com/rockchucks/ in Kalispell and there is a pretty big one or two in Missoula. I don't belong to either to far to go especially in the winter.

I bought a used Lortone QT-66 for a hundred bucks a few months ago. It ran fine and I thought I was good to go. While I thought I checked it thoroughly, one thing I failed to check was how tight the set screw that held the bully to the shaft was. It wasn't tight enough, and at one point the pulley walked up the shaft, and caused the motor to bind and then start to smoke. Fortunately I was nearby in the house, and between the acrid odor, change in running machinery noise, and 22 years of sensitivity to those sorts of things from my time on submarines, I caught it before it rolled over into a fire. The motor did not shut down on its own. Secure power to the motor and allowed it to cool, and ordered a new motor. The follow on story is that after it cooled, and I diagnosed the problem and repaired it, as an experiment, I powered it back up with the original motor, and it ran like a champ. You may well understand that I was a bit nervous about letting it go 24/7, so I looked into ways to both monitor it remotely, and shut it down remotely. I won't burden you with the research effort involved in that, but I found solutions that worked for me. A simple web cam, a cheap temperature probe, and a remotely operable smart home outlet allows me to view the rig anytime on my smart phone, and shut it down from my smart phone at any time anywhere I am in the world. Note that I made a compromise here. While I can remotely monitor the rig, I did not engineer an alarm system that would alert me if there were a problem. Cost was a factor in that risk management decision. I also added a couple of spare muffin fans I had lying around to the rig. One is attached to the Covington via super/whamodyne velcro, and the other just sits on the bench between the Thumler and Lortone motors. My experience since then is that all of that effort, while helpful, is likely unnecessary. I have hooked the thermocouple up to all of my tumblers and measured their running temperatures; the Thumler AR-2 runs the coolest, at about 77 degrees. The Lortone QT-66 (still with the original motor) averages 87 degrees, and the Covington Deluxe (6.5 lb. slant barrel) normally runs at 115 degrees. This is with both fans running. All of this is on a wooden bench with old wooden kitchen cabinets above and below, so with the fans running, if a motor does have a catastrophic fail that I don't catch, the house should up quick, and I can then use the insurance money to build a proper rock-shed! All kidding aside, each person finds their own way to peace of mind. I hope my experience is able to inform your approach with data that is cogent to your concerns. Here's some photos: Above, the whole rig. Next photo is Cocington cooling. Below, is the fan between the Thumler and Lortone motors. If you look closely, you can see the thermocouple attached to the Lortone motor with some stainless lock-wire. Sorry I couldn't figure out how to rotate the shot. And here's the cheesy $15 thermo I bought on Ebay.

I hear you on the too far in winter. 17 years living in the Rockies and I can tell you, I would rather run into a griz than drive on winter roads.

First it validates my concerns and the photos are great to see how other people set up. I probably will go the old fashioned way ... not run it when I am away. And, let's be honest, I'd never be able to lend that level of sophistication to my outfit.
