Looking good minkos61 (stupid questions following): Are the front legs adjustable to allow lowering of the front of the unit? To allow rocks to exit the trommel?

Where did you find that large sprocket?

Nice build!!  ;D ;D

Title: Re: Trommels
Post by: minkos61 on February 25, 2008, 09:48:22 AM
Thanks RockForBrains no such thing as a stuipid question! The front legs are adjustable to allow rocks to come out the barrel and also to set the sluice angle for proper water flow through the sluice. The sprocket came from Raeside Equipment but you can get them from Princess Auto and other places like that .When this sproket gives up I will change it from  #35 to #40 the #35 is a little light.

Thanks Ernie

Coupled with that sluice of your's you'll have full pocket's of gold in no time  ;)

 ;D Good build  I see you have put some time into it , LOL  a tad more than I have   even with the wood stove out here at -20 c its hard to get my butt out in the shop on weekends  Heres a Trommel Ive been working on  but a much smaller version  gona go with V belt drive and a Windshield washer motor 12 volt and high torque. sorry the shop is such a mess Got 15 things on the go at the same time  LOL  Great pics

Great job on that SnowSpider comin along great.I'm powering mine with a wiper motor to but chain drive next one might be belt drive I like the idea of the belt slipping if a rock jam's up.

Post by: SnowSpider on February 26, 2008, 12:38:39 PM
Yes  I thought about rock jams too but on the more enjoyment side  Its much quieter with the V belt Im guessing and  much easyer to find Pullys of diff size than sprockets and matching chain... Im prolly going to use my 5.5  Gas  Water pump to power it now that Ive got the durn thing working right LOL  may give it a test run as soon as the ice breaks up in Devon or Genissee  Devon is good but crowded and Gennissee   under the bridge is showing some really good colour and much quieter  Ahhh but the dream spot is still unaccessable due to a lack of a boat  LOL  a big gravel Island in the middle of the river  just  up here by Thorsby I can hear the gold calling me and the trommel to come and play LOL

looks great fella's...

SnowSpider I like the smaller size of your build, would be great for sampling or using on those 5 gallon pails we all collect :P

Minkos61.. Whens mass production start? ;)

The pic's if they come thru?? are of the spiffy 12V trommel I made this winter.
It's frame is made from 3/4 inch copper pipe cause I can't weld worth a darn but boy can I solder.

That is a spiffy unit lsfog, and being a lousy welder too :P your idea opens the door to many projects i'd like to start {cool^sign} {cool^sign}

Good looking rig there Ken.Does she work good? {cool^sign}

Hey  im a welder  and thats one fine job you did  and dont kid yourself  soldering is welding with just a lower heat setting  and works fine   Looks like a very fun rig to run  and  trust me  the most enjoyment in building your own rigs is the joy of seeing it collect even the tinyest bit of yellow good build  enjoy  and  have fun tweaking it LOL  thats the other half of building your own rigs  (There never finished)

Thanks for the kind words fellas.
To date all I have run and re-run is a pail of 1/2 inch classifyed left overs. As long as I kept the feed rate to a garden trowel full every 10 seconds or so everything was good.Truth be told I'm a bit concerned that it will bog down when I feed it bank run material. The 12v window crank motor has alot of jam but the hang up is the 1/4 inch thick - round - 14 inch diameter rubber belt that I'm useing for power transfer slips a bit especially when it gets wet.
Anyway thats where the tinkering & adjusting comes in.
My personal favorite part is that it nicely accomodates the 10 inch main sluice, then the cons are run thru the 5 inch Fine Gold Recovery [ thanks Florian ] sluice, then lastly thru the tiny Grizzly sluice all on one platform so to speak.

Hey Ernie,
Good looking trommel. You might want to add a 3" or 4" piece to the top of the hopper on an angle to protect the chain drive from gravel that will get thrown past the top of the hopper. I know from first hand experience. I built one from the same plans you are using. I made it a 10" drum and used 1/2" expanded metal on the barrel. I also used a fine stainless screen inside to further classify the marterial. My brother and I went to the Devon bridge and set up. There was a guy camped there and using a little camel. He watched us set up. We shovelled into the trommel for about 20 minutes and then did a cleanup to see how it was working. We had a little over a gram of gold in that time. The guy was amazed at the recovery. He said "I want it. How much?" We had more gold than he had in three days. Needless to say the trommel was sold and we promptly built another. I think one of the keys to the recovery was the vibration set up in the sluice from the weedeater motor used to drive it.
Good luck with your trommel and maybe we'll run into each other out there..........Jack

Thanks Jack you are right about the guard I will be adding that allready have the piece cut just have to weld it on. I'm just working on attaching the wiper motor for the drum drive then rip every thing apart and slap on a coat of paint make some riffles for the sluice and then she's done. {cool^sign}

WOW That's pretty!! Voice of experiance speaking ---you may have to do a slight redo on your discharge shute if it happens to dump onto your sluice----
How did you get your 12 v motor reduced to those just right rev's???
Again it looks great.

cool looking trommel.I work construction and can get my hands on alot of scrap pipe, ect.Been trying to think of ideas I can use construction scrap for this might be a lead.Thanks for the copper pipe frame idea,I own a torch, but no welder.

Post by: minkos61 on April 05, 2008, 09:29:09 PM
Thanks guy's it's almost there.
Isfog the sluice will be going out the side.the gears I used were 96 tooth on the barrel and 45 tooth on the motor,the motor is also a 2 speed hi & low 85 ford wiper motor.

Looks really good!  Any idea of run time on a battery?

I heard some other builders mention about putting a couple of bars on the inside of the trommel barrel to get the rocks to flip over and get completely washed. Do you think you will need something like that?
Title: Re: Trommels
Post by: minkos61 on April 06, 2008, 04:35:08 PM
Greg in BC thanks .I have heard that you can get a full day out of the battery but haven't tried to see yet, Bar's for the barrel will be going in shortly.

Golddigger thanks.
