Building the Gold Bump-Sluice Shaker Table 

By far the most well engineered and designed shaker table on the internet!

Made a Miller Table a few years back and found that the open cell foam used to keep debris out of gutters makes a perfect water flow 'straightener' for these applications. Water flows through it unimpeded but flows evenly down the table without bubbles.

Thank you for sharing your work so freely. It is truly appreciated.

Thank you for sharing step by step and detailing . I like your design.

I’ve learned a lot from your videos. Thanks for taking the time to share the knowledge you’ve accumulated.

I was amazed how you worked out those ending “launch points” on the table saw. That had to be a mind bender. lol. You are the king of craftsmanship, sir. Incredible work! God bless.

Que gran aporte! estimado señor... muchas gracias, de parte de un pequeño minero de colombia.

Excellent! Another interesting, well designed, built and documented project. Thank you sir.

Wow, so many improvements over the last table. The motor though expensive is so nice and super quiet. The driver electronics are interesting. I don't know why you needed a micro controller. Very nice method of implementing this off for the groove. Endings Much more feasible than the ramp syste.

Thank YOU for the detailed instructions

I like the moss at the spray bar.

Truly impressed! Thank You!

Great Video! Thank you so much for posting your build content! I am in the planning phase of doing the same thing. Which means YEEEAAAARSSS :)

Amazing. Questions questions question. Great video. Thanks for sharing all the great info.

Looking Good!

Thank you I've been looking for something like this! I want to modify it to catch #1 #2 cons

Great video thanks for sharing!!

I've wanted to build one of these Tables however I have a different approach in mind for the rubber membrane/mat Grooves. I believe the way to homemake a rubber grooved mat is to lay the rubber on a flat surface and add on one side a set of slanted shims used to create the walkouts for the Gold. By cutting the Grooves with a Router the Walkout is created perfectly through the Action of the Router climbing up the gentle slope of the Shims. This is the only method I can really think of which doesn't include Casting a Mould of some type.

I used to build the Bob Beck zapper. It runs on 8 cycles per second. Coming out of an LM741 op. Amp. I also made some that were adjustable frequency. Square wave output. 24 V. That input signal could drive the transistors to provide the variable output to the coil.

Boa tarde professor parabéns hein legal demais hein valeu pelo trabalho

excellent video

Thanks for taking the time to show your table build. I’m attempting to make one myself now. I love the drive mechanism. Do you think the table could be scaled up a bit with the same size magnets and coil? Where did you get the magnets? Thanks!

If it were me building this masterpiece! At 14:15 , I'd use a router and start at the shallow end. Slowly poundage the router in to about .060" and maybe to about .100" starting at roughly.010". Then sand with up to 400-600 after the epoxy! Although I would have probably added a couple layers of fiberglass, the thin stuff. That looks like tissue paper and possibly bake the wood at 215°F for a couple hours. Drive away any moisture. Then a thin epoxy bath possibly under a vacuum. the vacuum infusion should stabilize the wood for many years sitting in the weather before it even starts to rot! Possibly, 20 depending on UV exposure. With the fiberglass layers it could incorporate Led strips inlaid under the fiberglass along the end of the grooves. The fiberglass being transparent a diffuser layer would be required. A thin layer of silk like cloth or cotton under the fiberglass! A pigment may be used or a gel coat! A white gel coat could help with black sand contrast! Or a pigment added to the epoxy! A wet sand and buff to smooth out the surface , then a 400-600 grit orbital sander to give it a matt finish, and give the gold a little traction so the black can scoot on by! And the collection points I have tiny funnels with about 1/2" outlets to allow a bit of 1/2" hose to be used If desired. Use a bunch of measuring cups / containers for the concentrates. And a gold or panto pre catch the tails close to cons. Before overflow into a large tub to be filtered through a large coarse sand filter divider in the tub with the sand collecting in a smaller tub in the large tub! That will over flow into the larger! The two stacked gold pans used to test the tails for gold lost! Without loosing anything , after testing and dump the pan place it under the other so nothing is stopped or lost! But the thing is, I gotta find the gold first!! Then get it before even thinking about this Part of the process!! Great video, have a awesome day!!👍

thanks for the vid

Really enjoy your engineering , great looking shaker , would you be willing to share or sell your wiring diagram ?

mantap

I just guessed. Our hardware sells 1200x2400mm So I got a 1200x600. Bugger

Hi, I have a suggestion that might help you. Instead of electronics why don't you use a massage viberator? It's simple, easy and cheap. I would appreciate your feedback.

What type of Garolite are you using? G10, G10/FR4, xx? Thanks, your videos are extremely educational

Bloody awesome build, video and explanation. Well done! Did you come across any issues with the magnets holding up magnetic fines on the shaker table and if so, how did you remedy?

Have you seen flour gold wizards he definitely is passionate about flour gold he's rugged but knowledgeable inventing a flat flow sluice head

Hi it’s me again. I’m building this and as you can tell this is way above my level of intellect so bare with me. as I go I’m running into little things that I’m confused on. In this video you specified a 150w 10-32v to 12-35V 6A step up Boost Converter. In the electronics follow up video you specified a 250w 10-40v to 10-50v 6A. One has heat sink one doesn’t. Is there a reason why you recommended the white one over the red with heat sinks? Also you mentioned that there’re (3) 2pin female plugs on the side of the box. 2 for the motor coil, and 1 for the pump. Why is the motor coil taking 2 outlets- wouldn’t (1 )2pin plug be enough to complete the circuit? And a dumb question : By using the mcu -are you are able to control the speed/ force of movement to one side? Say it moves to the right and then abruptly changes direction to the left. The gold continues forward with inertia - in theory wouldn’t quick\sudden change of direction eliminate the use of a bump plate or is that not enough strength?

😮

Very nice design. Have you considered offering kit?, at least for the linear drive?

By far the best table design that I have seen. I would like to build your design. However, I can't get the drawing to open up for me. Can you help me out? I have downloaded the sketchup 8 but I don't know where it fouled up.

There appears to be some design/part changes related to the electronics box in this video compared to the more recent video "Linear Motor and Electronics for Bump Shaker Table" and the "Gold Bump Shaker Microprocessor Board" video. Different components, etc. Is this the case?

Question, did you try higher frequencys that are higher? 400hz? 1000hz?, 4khz? According to building engineers who built buildings for high earthquake areas There is something called liquification Factor we're small solid grains start behaving like liquid At very high vibration frequencies And if a solid will behave like liquid Then weight separation would happen a lot better thanks for sharing

I'm in South Africa can I send my superfine gold to you

Is a shaking miller table feasible , or am I missing something obvious ? EDIT : NVM - I just scanning thru your very first tape and there is mention of one. Have you continued with that project or has it been abandoned ? I'll probably find the answer in some other tape.

I am having trouble sourcing 3/4" N52 magnets. Will 1/2" thick work with a modification to the coil? My school only lets me purchase from Amazon...

Really appreciate the fact you freely share your information. you are very inspiring and i would really like to make one of these. is there a way to contact you outside of here?

3D printing is cool. A lot of people are printing these days.

Howdy, how much would it cost to buy one of these you made?

On your last video you said your micro processor wasnt necessary. It all seems quite straightforward, but you loose me at the chip.

I’m not familiar with sketchup at all. I can’t seem to be able to pull up a part list. Is there a way to do that?

Hello sir I hope that you might look at my comment because I really want to know your knowledge well all of your RU-vid subscribers you like are similar I'm not an engineer but I know just about everything I apply myself to and it's gold learning the fluidity of water the density of gold the price of gold and life if short I'm already capturing gold from black sand living so close to Lake superior it would be so great to have correspondence with you I'm a almost 40 year old Menominee native living in upper Michigan and want to take advantage of what knowledge I have and can receive to be successful before the end if my time plus I love gold mining Placer not hard rock couldn't see myself being crushed. Thank you for hearing me. Have many life passions and I see your passionate have a great day.

When will you sell them?

Are you selling like that ???

Hey how much would you billy one of them for

what programe did you use for the files

I need you to contact me before I continue my build
