You look very much like the guy who has all those Youtube videos which are amazing by the way. I have seen one or more of your enclosed tumbler cabinet and need to share with you why each time that I have seen it it scares me half to death. There is a lot that can go wrong with tumblers, with the motors, the pulleys, the belts, etc. If the motor that drives all that is inside the cabinet, and I'm guessing that it is, that whole cabinet could easily go up in flames if there was a mishap.
A few years ago, I had a barrel blowup, heard it happen, and went out into the garage and found some rocks jammed against a pulley and the belt was slipping and faint smoke was already happening. This was in the open and so no enclosure to amplify the heat. Granted that if you only have 12lb Lortone barrels, the risk of this pulley/belt issue is almost nil due to the way they are constructed vs. full v-belts as I have in my large barrel bases. But even if so, you still have those motors that get very hot. Just as leaving a dishcloth on a stove top isn't safe (no matter who says the stove stop will always be off), electrical motors and even the cords to them can fail and failures can start fires or get hot enough to trigger combustion in adjacent materials.
You seem like a very fastidious guy and so probably are way ahead of me on this, such as you may have some type of automatically-triggered fire suppression system overhead or some other fancy method to deal with it. But, I could not in good conscience not mention this concern, because I don't want anything bad to happen to one of my fav makers of tumbler videos!

I have a YouTube channel called "Michigan Rocks". Chuck ( Drummond Island Rocks) designed my tumbler and he has one very similar to it. It's his second tumbler designed basically the same way. The motor is mounted on top so that it doesn't build up heat inside the cabinet. I have a GFI outlets in the basement where the tumbler is. I also have a cord that won't let the tumbler restart after a power outage. I bought that before I had this large tumbler because my Lortone QT66 didn't have quite enough power to start a barrel from a dead stop. The pulleys are a ways away from the barrels. The bearings are in between the barrels and the pulleys. I had never really considered a rock jamming and creating friction, but I think the rocks would fall to the bottom of the cabinet rather than getting jammed. I appreciate your concern and I'll take a look at the tumbler to see if there's a way I could make it safer.

I think you may have been watching somebody other than Rob's YouTube vid's.......surely, what Rob (Michigan Rocks) and Chuck (Diamond Island Rocks) have built and have been using successfully for nearly two years now (maybe longer), have/had considered all of your "safety" concerns during and prior to their constructions......and have even fined tuned their machines over time.
Or, it may simply be a case of your lack of mechanical/electrical aptitude and knowledge that's causing you concern. In any event, your concern for electrically charged or friction driven combustion issues are "way over the top" and quite frankly "phobic" in this case..........The kind of heat transfer or electrical ignition you elude to, on the scale of a catastrophic event in their environments, is nearly none existent.........try spending a little more time and attention to the detail these guys have gone through.........these are no DIY, backwoods, makeshift garage guys..........Thumb through their links here at RTH......You'll see what I mean. I have not personally seen or visited either of these lapidary Master's shops. Nor do I personally know them or have an invested interest in their endeavors. But, both have posted many videos and photos of their working environments, tricks to the trade, their operational equipment staging and various tools they use. Both of these gentlemen have a very high degree of practical and professional knowledge and both, to some extent, do not spare cost or perfection in their craft(s)...... one could probably eat off their shop counters and floors......lol
Anyway, your concern for safety is admirable. However, in this case, you just may be the "elephant" in the room.
