I have heard that tumblers shouldnt be left unattended as they have been known to overheat and catch fire ....:runaway:

true?
false?

Old granny tale?
 
I've never had that problem with my tumbler.

i guess they are like any electrical product. Space heaters have been known to catch fire.

I suspect the more expensive the tumbler the less chance you have of a accident.

I have had my dillon tumbler for over 15 years. Still works great.
 
I have no problem with my Lyman Tumbler. Just make sure it has enough space around it for airflow and it will be fine. By that I mean don't leave it running in an enclosed space like a closet or put it in a box . Personally, having to sit and watch a tumbler vibrate for 2-3 hours would make me give up reloading. I enjoy the hobby but there are limits.
 
My Lyman Tumbler runs 3-hrs one after another batch 2X on Saturdays (6-hours total at least) everytime I get back from the range for at least 3-years now with no overheating and exploding problem <knock on wood> :)

Please remember, unless you are using an inferior brand that you bought from who knows where.. you might have that problem, but you have to remember brand name brass tumblers that are being sold in your known sports stores are Tested and CSA approved before it hits the Canadian market.

Those explosion are Myth??? Old Granny Tale?? I hope so..... :)

I left my tumbler on one day for about 14 hours or so as I did not come home that evening to turn it off. :D

Anyways, no biggie. It was some what warm to the touch but nothing that I didn't expect from the friction of the media in the bowl and and vibrations on the base.

Go go Lyman!
 
I always leave my Lyman on for 4 hours or more at a time and I have had it for about 15 years now. I do know a guy whose RCBS tumbler overheated while he was out of the house, it had some sort of overheat protection which just shut it down. He told me that he was wondering what happened as it was on when he left to go out, it was screwed but at least it didn't catch fire.
 
I believe Lyman, RCBS and a couple others all use the same motor in their tumblers. On that note, I have ran both my Frankford Arsenal and Lyman tumblers overnight with no problems.

Any tumbler sold in Canada should be certified to CSA C22.2 #(I forget) as a motorized appliance, and anything certified as a motorized appliance must have an internal overtemperature fuse.
 
a friend of mine had the bottom bearing shake loose, and the tumbler caught fire. Though that doesn;t exactly make them 'prone' to it, any more than any other electrical device left on and unattended.
 
I've left my Lyman Turbo 1200 tumbling for well over 12 hours at some points by itself in a 'safe place'. The motor is warm afterwards, but not burning hot. The fan on the underside seems to be doing its job. That little tumbler is just great, but I suppose everything has its limits.
 
My Franklin Arsenal doesn't get that warm but it did break an electrical connection to the motor from vibrations just recently. I repaired it myself and she's still going strong now. I routinly leave my tumbler unattended for hours at a time with no worries...yet. :)

I agree. I've had mine rattle so hard that I thought I'd lose the bearings, but I've left mine on for 4-6 hours cleaning range brass. (And it STILL needed more cleaning...)....
 
My Hornady has run for 3 days straight just long enough to empty it and restart it. Have been doing some uglies and like to give them 24 hours at a go. So far so good motor has been warm but not hot.
Ken.
 
If you are afraid of letting it run to long, just buy a timer and plug it in. You can get one those timers you plug lamps etc. into for about 10 bucks. Set it and walk away. Just remember some will come back on 24 hrs. later.

This is what I did. But, if you look around you can find some models of timers have a "countdown" function. You can program in a duration and it runs for that period of time, then shuts off. I got one from Can. Tire that will program any duration from 1 second to 23 hours, 59 min. 59 seconds.
