Shaker Table Driver

- I've been wanting to build a really good drive unit, for a shaker table, for quite a while. This winter the plan finally came together, and over several weeks of drawing, and building, with many mods along the way, it finally came together. I hope my explanation of how it works is adequate. I may do a followup video with a more detailed explanation, of how the geometry effects the stroke speed at various points of each rotation.

Impressive ! you really did a great job figuring out the original design :)
Love it. Can't wait until you have some plans for it as I would like to make one.
Plans are $40 here, or now $50 from EBay.
Beautiful build Jim, as always!
Many thanks, Jon. Hope you're doing well up there. Is your snow gone yet?
@@jimnelson7740 Jolly joker. We're 10 degrees below seasonal average, looking forward to a balmy high of 30F on Easter Monday.
@@rexhavoc5643 aah man...that sucks. We're finally warming up...mid 60's today....almost too warm with the high elevation sun beating down.
you built a good one
Many thanks, Frances! It sure took me awhile...LOL I'm currently building a Pleitz-style mineral jig. I'm REALLY looking forward to using that in Wyoming next summer, for diamonds.
Nice brother
Thank You
Beautiful!
Many thanks guys! A customer in Chile has built the drive unit. Did a really nice job, too. Made a more simplified unit. he also did a great job on the table. He was just getting to the point of testing last week. I'm hoping to hear from him soon on the testing results.
@@jimnelson7740 It would be cool to see how he did it
@@jdeluisa I've got a pic of the whole machine. Just a short view of the drive unit. Not sure i can post a pic on here, or if I should without his permission. I asked him for more pics of the machine. We'll see what happens. One thing he did was make the toggles out of thin material (maybe 1/8" plate?), and used some simple material...maybe plastic for bushings instead of sealed bearings like I did.
This is slicker than cat shit on a linoleum floor, being a welder/machinist I can see me having to build something like it.
Hope you do! Send pics when you get it done.
Jim, do you make them to sell or sell plans ???
I've got plans to build them, along with pics and instructions. I don't make them to sell....I'm too old...LOL They do require access to machine tools, like a lathe and mill....or, if your real handy, you might get by with just a drill press. I charge $40 for the plans. You can pay me through PayPal, and I'll email the plans in PDF format, or I can send the raw CAD files, which is more workable, if you can read .dwg files. CAD readers are available free online. I've had no complaints about the PDF version, however. My PayPal ID is 'jrnelson_536@q.com' Thanks
Would a vibrating table work just as well as a sliding table?
Unfortunately, no. The shaker table has an action that moves faster in one direction than the other. That's what makes the heavies go up the slope towards the cons end, while the lighter material gets washed down the cross slope into the waste troughs.
Jim Nelson thanks Jim... Curious about the blue bowl too.... is that just as effective as the shaker table?
@@TheSummersProject Actually, they are two different tools for two different jobs. The Blue Bowl does well with really fine gold, whereas shaker tables do best with a bit larger gold. Shaker tables don't do really well with flour gold. I've often thought about, and still intend to build a small wave table, which would probably combine the best attributes of both. I think for a small scale miner, like most of us, a small wave table would be the best setup.
Jim Nelson thanks for the response. 😃 So, I’m getting into e waste... Lots of boards etc and about to grind them down. If I get them down to a fine powder, I’m assuming that’s what you mean by flour gold, just so I’m clear, for the finer stuff like the flour, I’m better with a wave table? If so, are they easy to build? Expensive to buy?
@@TheSummersProject Somebody was selling small models on EBay a couple of years ago. I haven't looked for one recently, so don't know if they're still available. They're fairly easy to build, except for the drive unit. That part, if done correctly, requires some machining skill and tools. You can see mine on my channel. The same unit will drive either a wave table, or shaker table. I'll try and find the video of the one the guy was making and selling on EBay. I think he was charging in the neighborhood of $1,500.
Did you ever make the table top?
Nope. I did build one for the Wilfley Lab table I rebuilt a couple of years ago, but didn't make one specifically for the drive unit I built. Sorta lost interest in the whole thing, and moved on to other prospecting designs. I have a new dry sluice, which works really well, even on flour gold from the Snake, but I'm not releasing any info on it, until I get the patent application filed. Thanks
Jim
@@jimnelson7740 your design looked really nice. I currently am building a shaker table have everything done but stuck on what type of drive I want to build. Your design looked very promising.
@@dirtypawsgoldadventures Actually, my "design" is just a rough copy of Wilfley's original design. He was a real genius. I do some design work, but not in this case. But, my drive unit is easier to build than Wilfleys, so better for Diy ers.
Jim
Couldn't you just have used a motor speed controller. Awesome build
Thanks for the comments, Vince. You can't use a speed control with a single-phase A/C motor. You can with DC motors, but DC motors are spendy, unless you find one from a treadmill or other use, and then the max speed is really high...like 5,000 rpm. Hard to control that down to about 300.
@@jimnelson7740 clutch motor or Single-phase motor frequency converter？
David, frequency converters only work with 3-phase motors as far as I know. I like the simplicity of the variable-speed pulley, too. very dependable.
do you sell the project? if so, where is it selling from?
No, I don't sell them. They take a lot of time, and the price would be too high...thanks.
@@jimnelson7740 I live in Brazil. here the products related to gold mining are very expensive. whenever I can, I make my equipment. only a concentrating table is missing.
@@rnrfp The table is relatively easy. The drive unit is not. It requires several days of work. Shop time is about $500/day, including my equipment. I will try and get plans drawn-up this winter, for people who want to make their own. I have plans available for the table.
@@jimnelson7740 for me, the most difficult part of the job is the table top (the shape). I don't know how to work with fiberglass mold, I will have to learn. the bottom part I already did some similar things in other segments. if you want, send me hi on whatsapp, i'll send you some pictures of what i've already done.

@@rnrfp Sorry, Ricardo, but I don't use whatsup. The table I made is made with ABS plastic. It's glued together. You can buy sheets of the plastic online. I use 1/4", or 6mm. For glue, I used regular ABS plumber's glue. The glue is a mixture of powdered ABS acetone. it can also be glued together with a chemical called MEK.
Jim sent $5 to see if I can make contact. if so will send the rest for a set of plans.
That'll work, John. My email is that's at gmail My PayPal ID is That's my old email addy.
Are you on FaceBook? I would love to buy the plans from you
You can reach me at at gmail (disguising my email from 'net bots)
Can I buy from you?
Trust me, you wouldn't want to pay what I would have to charge. Takes too many hours to build one.
Jim
Hi would like to purchase you plans to build. If you can let me how to pay.
Thanks
Thanks, Adrian. You can pay via PayPal. The plans are $50. My PP I.D. is I ship as soon as PP notifies me of payment. I ship by email. The plans come in both .pdf format, and as raw .dwg files that can be read with a CAD reader, or drafting program.
Jim
Adrian, I need your email addy. Contact me at my PP I.D.
Have been trying through PayPal
I can't send my email through here it deletes it each time I send it. It's in paypal and leaves a space in the address it has no spaces in it
@@adrianmauler1942 We're good...plans sent. Just for the info....even on Ebay you have to disguise your email address. EBay even told me to have my customers do that, as they have no system for emailing intellectual property. So, with gmail, for instance
😂😂😂😂😂👍
