This has to be my favorite DIY blue bowl video yet! Feed bowl at tractor supply...see these all the time! It’s thick, durable...and more surface area. Great job!
Looks like a winner to me. You may want to check your infill flow and speeds to make sure the extruded line being laid down just butts up against the line laid down previous. Too much or not enough speed and/or flow may lead to over/under-extruding leaving small hills or valleys in the print.
Cool!! I like your multi flute tapered helix cone appararus you got there. Your cad skills are getting better. Also went to visit Bruce today in AZ defenatly got himself a good hardrock mine. You should see his samples.
I like how you spin it clockwise so you won't be fighting the Coriolis effect. Would the sand flush better if the center cone had a longer more gradual taper? Perhaps add some Drano Ultra in the pan so it flush better.
Did you try the cone helix in reverse to water flow? Looks nice. Do you think I would be able to make the cone press on interchangeably to a thru hull fitting? Another thing I have been trying to work out is a DC variable electromagnet held up above the cone on a alum rod to assist the lifting the black sand to help it clear faster. I haven't ran any time trials but I think it's faster.
Running it in reverse I don't think would work at all. You might be able to make it interchangeable it's worth a try. I would take out the magnetic material first before it goes in the bowl.
@@alanrobertson2510 having the reverse helix cone would be like riffles the fine gold would have to cross, instead of spiraling up the cone. I'm looking for the magic shovel beach directly into bowl and dont want to mess with magnetics first. I'm gonna buy 3d printer Friday, any tips on what I want?
@Alan Robertsom... Hello bud. I love your work. I was looking for a mold to matt my blue bowl. And I used the bottom of a 5 gallon bucket. It even had a hole. it worked pretty good. I'm going to buy some nugget trap molds from you. You rock!!
Have you checked the loss rate for this? Does the flour gold stick to the mat or just get blown out? I have to admit it’s pretty damn cool! You’re a genius!
Hi professor Alan , I think I'm going to take my Tom and Perry's gutter sluice and take the matting out and and make it into a silicone mold. It's a simple grooved matting. I don't need complicated. I figure I can just run your soapy silicone on it and roll it out and just flip it over after removal from the old mat and I will have a nice clean up sluice. My other question professor Robertson, is since I like to do things the cheap way, do you think a water pump from a ice machine would run my gutter sluice or a condensate pump for an ac unit? I don't know how much that they put out. How much do you need to run a small gutter sluice. I'm like you I can rig one to work. The 110 volt ice machine has a bout a 2 ft drizzle of water. I don't know how much it would put out in a 4in gutter, do you?
Good idea I would suggest pressing the silicone into the mat with a board to get it to come out right. I have no idea on the pump and water flow, give it a try and see what happens.
I use a 780 gph bilge pump I bought years ago and it powers my blue bowl or a gutter sluice, I was thinking of upgrading the pump to 11-1200 GPM ($15 to $30) for a little extra oomph and also adding a Y hose ($5) connected with shut-offs so after a blue bowl run I can use the 2nd hose to rinse my treasure into a pan for further/final attention! I could also use it to replace the dirty water. It's a pain in the ass to do maintenance on a recirculating water supply, mine is set up in my living room!, so being a lazy person I try to simplify all the work needed to run and maintain my project. I've also thought of quick-connect hose adapters for tear-down/assembly when the whole unit needs a good flush and clean!
Another great idea Alan, I think that will be my next project. I guess I did something wrong with the mat for my Blue Bowl because it floated.....lol, but a cheap bucket I'll just pour the silicone right into it. Thanks for another cool project. Happy Thanksgiving
you didn't do anything wrong with the mat it just needs to be siliconed into the bowl you will have to do the same with the liquid silicone as it will shrink and the material will get under the mat. Happy thanksgiving.
Oh! I forgot to ask you how much silicone would it take to fill a 6 ft, 2in. by 12 ft 4 in. mat one half in. thick at a 25 degree angle with the wind blowing forty two miles an hour at 45 degree temp? LOL sound like one of my old Physics questions. My guess would be the wind , the angle and the temp wouldn't apply. What's funny is I would probably be wrong. Merry Christmas Alan to you and your family.
works quite well ! I would be interested to see you print a whole base or mat , and cone all in one piece , and run the spiral ridges running from the top of the cone down and then spiraling out to the edge of the base in the water flow direction ! how say you ? I reckon it would work well , make in Blue, I'll buy one !
Making one of these is a piece if cake. The cone is SIMPLE. all you do is scribe lines on a funnel and cut to the line,or even better-cut the height with a hacksaw blade supported at the correct height and move the funnel. The rest is even simpler
Well mr big all ..i made one of these ear fancy hury gurdys with a bunt cake coontainers ..havnt tested it yet .. burrt im calling it the smoochie coochie..😍😎😁pip pips and carryon pilgrims
