I live in an apartment. I have yet to begin my first batch. I plan on having my tumbler in the living room (farthest room from my bedroom), my question is: I've heard you can make a 'house' for it to dampen the noise with a box and heavy blankets, my concern is heat build up and fire hazards. .. Suggestions? Tips? I want to minimize the noise while staying safe... In theory I could put it out on my balcony but that's slightly against the rules of the complex and I don't want to risk it. I could put it in the kids room (they don't sleep in there) but that's next door to my bedroom... I feel stuck! I was liking the idea of making a little tent for it until I heard these guys run Hot. (Lortone 33b) What? Should I get a tiny fan and make air holes? I dunno what to do...

Run it. The noise may or may not be objectionable. The 33b is not large or particularly noisy.

I second that notion. Compared to the larger barrels, I hardly notice the 33B from across the room.

I have a 3A and it is fairly quiet, I have it sitting on top of some foam-rubber which absorbs about half the noise.

I find the sound of rolling rocks to be soothing. Kinda' like the sound of surf on the shore or rain on the roof.

The 33b, like the 3A do run a bit hot. In the warm summer months it becomes slightly alarming, but the internal fan seems adequate. I don't think the heat is enough to melt a plastic coated Styrofoam cooler WITH THE TOP REMOVED (so hot air can escape). Clipping a small AC personal fan to the side of the cooler with airflow pointed into the enclosure would be a plus also.
I like Wooferhound's suggestion of placing the tumbler on a rubber mat or pad (inside the cooler). I put all of my tumblers on a sheet of mesh rubber matting - normally used inside cabinets and work surfaces to keep items from sliding around. It seems to cut down on the noise a bit. (I also use the same mesh rubber mat material to line the metal screen in the bottom of my "classifying screen" that I use in place of a colander while washing rocks between loads - keeps the metal from scratching my shineys.)
You do not want to totally eliminate the noise. You will develop a feeling of what goes on inside the tumblers based on the sounds you hear... a smooth rolling shooshing sound might indicate a good tumble, while banging around might indicate a tumble that is violent enough to cause damage to the rocks inside (time to check the slurry thickness). It is like listening to the breathing of your kids as they sleep... you will be able to tell they are OK and safe. Like Grumpybill said... soothing.

Now, with all that airflow, there will be the dust.
Other Observations ... Did you add those power switches to those 33B tumblers ? Those barrels are way too clean, are they used yet ? The labels are still on the lids, so they are new ?

The Lorritone's have only been spinning 2-1/2 weeks been emptied recharged twice. Those fans put out 110 CFM quite alot for a fan of that size. ~Duke

One word of caution this is coming from a 35 year HVAC Contrator sitting these on insulated surfaces will only build heat instead of dissipating the heat. I Agree it will muffle but be careful how you do it. I would like to follow-up on your caution Duke... I hope I did not give Crystaltreefrog bad advice... Do you think using a Styrofoam cooler without the lid will end up generating more heat to the tumbler... or the rubber mat under it impeding ventilation - causing more heat... or both? This might change the way I have my own setup.

What I meant was there is a reason these tumbling units have steel or metal in proximity of the motor and that is to use as a heat sink and it draws heat away from the motor which is a good thing. sitting these units on Styrofoam carpet or other insulated material does not provide heat transfer. What I meant there just needs to be care in placement of insulating type materials is all. These fans will cool the motors I have proven that but her problem is two fold cooling/and sound and complicates things further. the fan also improves the fact that the tumbler sets on insulated materials where there is no heat transfer. If you look at the Lorritone the whole blue body of the frame is a big heat sink that draws heat away from the motor area of that unit. If you set the unit on PLUSH TYPE FOAM where the unit will sink down a 1/4" or 1/2" into it will block some airfow on the base of the lorrotone. I have not proven this but this is what is happening and I will prove it soon just have to think where my infrared thermometer is. been awhile since I spent time in the garage gotta get my bearings back. So no disrespect meant just need to be careful and think of these things is all. Cheers ~Duke

Thank you Duke for enlightening me on the subject. I will remove the rubber pad below my tumblers to allow better heat dissipation. It now looks like my advice to Crystaltreefrog was not good advice. Sorry Crystaltreefrog! I no longer think the Styrofoam cooler solution is correct.
Thank you again Duke! Glenn

Sorry Crystaltreefrog! I no longer think the Styrofoam cooler solution is correct. Thank you again Duke! Glenn Brother Glenn it might be okay with fans blowing I would hafta run temp tests. Now Putting a cooler over them with fan in blowing over mtr and fan out might be a better option I don't know. As far a noise goes yer talking to a guy who's had mastoidectomys on both ears Cant hear Jack Didley comes in handy when the wife asks me to do something! I sleep with a fan running so like others have said it all depends how critical you are to noise? I would get some fans from amazon they will only cost about 50 cents a month in electricity. ~Duke

Anything soft is fine as long as the frame doesn't sink into it any. Styrofoam is certainly fine as well as the carpet pad that I am using and the rubber pad that you are using. I am not too concerned over a 20 degree difference in temperature. The machines are designed to run that way.

SO... you are spending $20 per fan per tumbler to cool motors that are running at the temperature they are designed to.
As long as it makes you feel better, go for it. I seriously doubt the motors care.
Been running many Thumler's motors for 10 years. Never had one quit working.
