Big storm tonight and the power went out momentarily. I had to run some errands but luckily thought to check my QT-12 before leaving, and it was sitting motionless ... motor whining but not rolling. I reset the barrel and it seems ok, but it got me to thinking, what if it happened when i was asleep or away from the house for hours? Anyway, does anyone have an economical solution for this situation? I've considered a UPS but i wouldn't trust an inexpensive one to power the tumbler for long, and i don't want to spend hundreds of dollars. Unplugging the tumbler at night and when i'm out of the house also isn't appealing. What do you seasoned vets do to protect your tumblers from a temporary outage? Been about a year since tims created this thread... I would like to revisit it again. I experienced a 30 min power outage a few days ago. One of my two QT66s failed to start rolling again when the power came back on again and required a push-start. Neither the Belkin power strip nor the GFCI breaker tripped off-line. I would like to find a commercial solution which requires a manual reset that goes between the wall GFCI plug and the power strip. I am not looking for a home-brew one (I am a 2-wire kind of guy and 3-wires scare me. I am also very lazy... and am a couch potato who would rather buy from Amazon). Like tim, I looked into the in-line manual reset GFCI switches... BUT am concerned that it will NOT trip during a neighborhood power outage... like quartz stated regarding his "Defiant" brand plug-in GFCI. Is there a commercial solution... ready-made?

Not sure is this is what you mean by ready made as you need to wire it in but I just bought and installed this one and it works the way you want...if the power goes off you have to push the reset button to get it going again...and it has the GFCI capability. I have all my tumblers on a power bar so I wired it inline... www.amazon.ca/Leviton-16694-15-Amp-120-volt-Right-Angle/dp/B00HRF32FQ/ref=sr_1_1?ie=UTF8&qid=1526407472&sr=8-1&keywords=Leviton+16694+15-Amp+120-volt+Manual

I have been known to forget my own name sometimes parfive . Lol! Tried to do a search but that thread did not show... and too long ago to remember. I will order the one that Noosh9057 recommended... before I forget again. Thanks!

Guys. People with freezers in garages have this issue... once every 3 to 4 years we all know what happens.... gfci is for protection, and typically after years, brownouts..etc..can just trip. For my freezer i moved to a non gfci source.Volia.
Want protection? Add a powerbar. Gfci is not meant for long term /dedicated device. Look in a laundry room. 220v non gfci outlets for your appliances. Then the outlet is 110v is gfci for your added protection.

If I was going to tumble rocks seriously I would have a detached sound insulated steel building that is inexpensive to heat in the winter and strongly ventilate in the summer. Full concrete floor sloped with a 6 inch floor drain sloped well to prevent clogging to a catchment pond/vat at lower elevation close to the building. Or into a sloped forested area. Similar design to a meat cutting room with lots of water plumbed in with a waterproof electrical system so that the equipment can be washed down. I would not mount tumblers above one another due to the fact that caps often fail and abrasive slurry leaks and damages the bearings on the tumblers below. To me tumbling is best done in a wet room with industrial components and electrical layout. Emphasis on a large sink and open top tanks to assist clean outs as ergonomically easy as possible. It is a nasty messy operation that requires a lot of fresh water and attention to cleanliness. Rotary tumblers on one side of the room and vibratory tumblers on the other side. Perhaps a 10/20/40 foot long oversea container well insulated with poured floor as they can be purchased and set inexpensively. These recommendations after running 100 pounds of rocks at high production rates for over 5 years and doing 2 to 3 day clean outs at coarse grind on 4 to 5 twenty pound barrels. 1000's of pounds of clay slurry, 100's of pounds of coarse grit. Lots of messy waste. A miniature version of this meat cutting room:

I did purchase that GFCI cord but haven't had an outage with the tumbler running since then. If it happens, and chances are good now that it's thunderstorm season, will share the results.

I was thinking about this shut down thing. The only time rocks should concrete in a rotary is during coarse grind in a rotary, maybe 220 step. When slurry is present. It takes slurry to create a concretion, right ? Maybe in a vibe for those that use SiC 120/220 with puzzles me anyway as that step is best done in a rotary. AO/Sic 500 creates little slurry, can't see that concreting. AO 1000 and polish creates no noticeable slurry.
So, if you get bruises from a concretion in coarse grind it should only take another addition or two of SiC coarse to fix your bruises, right ?
Perhaps some rocks concrete in finer abrasives but it seems unlikely.
I tumble glass and glass slurry is the worst in the world about concreting quickly. In 60 seconds. I am in a hurry when removing barrel and pulling cap to make slurry adjustment or grit addition, never turn machine off during coarse grind.
Try colloidal clay for slurry thickener. It stays suspended in water longer than any clay. Reusing slurry ? Well, I don't. I use fresh colloidal clay every clean out. It is a known fact that industrial slurries that are usually clay based and simply wear out. Colloidal(platelet)clay is made up of flat plates that suspend in water. Once the plates break down the clay sinks fast and can concrete.
An example of industrial slurry is in mining operations when they need 'heavy water' or 'dense water' to float off unwanted debris when crushing/separating ore from matrix. They make heavy water by mixing cheap colloidal clay in it, it has flat particles that sink slowly making the water heavy. Heavy water floats heavy particles. Similar to floating dense abrasives in our little tumblers.

I ran a recent Lot-O batch and turned it off every night because I don't have the ideal tumble room. It seemed to work just fine.

You may want to re-read the earlier responses by MrMike and alternative solutions that were shared by other members. You are going to be disappointed if you are counting on a GFCI to prevent your equipment from restarting after a power outage. A GFCI isn't designed to trip and require a reset after power interruption, and the "Test" and "Reset" buttons aren't designed to be used as a switch (though it will function as a switch for awhile). In real basic terms a GFCI is designed to trip when the current passing out of the outlet from the hot wire doesn't match the current passing into the outlet to the neutral wire. Such a condition occurs when the current returns to ground through a person instead of through the outlet. The sole purpose of a GFCI is to try to protect people from being electrocuted. It has nothing to do with controlling a power supply. Just sayin'.

Look up Leviton GFM15-3C on ebay. Manual reset gfci.

"An automatic reset turns on upon being plugged in or after a power interruption. A manual reset requires the user to press the reset button after initial plug-in or after a power failure."

None of my GFCI's trip when my power goes out. What you really want here is a latching relay. You can buy them prewired, or wire your own easily enough.

My apologies - that'll work.
I wonder why nobody suggested doing it that way.

Your post was spot on, Ground Fault Circuit interrupters are for when current is flowing where it shouldn't be. If the power goes out, and comes back on that should not trip a GFCI. So if you're worried about a restart after a power blip, the latching relay is probably the best way it seems to me. I have them on my saws, mostly so I don't get an oil bath when I pull the vise back!
