It is backwards. I think I talked him out of using it, it was made for a 2" dredge but I never made the dredge. Not much dredging in Arizona. Anyway, AZ has a hopper on the drawing board that will fit and work much nicer. Not so high you have to stand on you toes to dump a bucket.

Yeah I mounted it backwards on purpose. Does not fit the other way. I had planned to modify the hopper but plans have changed. I could have made it work but the top edge of the hopper would have been to high to shovel or bucket dirt into the hopper. JustBent does nice work.
 

Way to go Keith.
Looking good. Now let's get this beast going.
I'm hoping to get back out in a couple weeks. I picked up this cold or flu that others have and I'm not thrilled with it, for sure. I've heard of others getting pneumonia and hope that wouldn't be the case.
How's your brother and your shoulder doing?
 

My brother is doing good. He tried to speak his first words last week and my sister was able to understand what he said. I will be seeing my brother on the 3rd. I met with my surgeon this morning, they did a series of x-ray's and everything looks good. I start PT on Monday and currently can lift my arm 90 degree's. Have very little strength. I will continue to be in a sling for another month of which I see the surgeon again. The plan is to come up to the Phoenix area on Saturday the 18th of which I will be stopping by Jay's shop, the plan is to go over to the GPAA event to have a look.

You really need to watch that pneumonia as it can get out of hand quickly. My good friend lost his 20 year old son two weeks ago to pneumonia.
 

I'll second the pneumonia warning. I had ortoscopic on the knee and they didn't think it would be a problem since the surgery was so short but I was seriously messed up. 103, 104 I forget how freakn high it got. Surgeon's office said to call my doctor. Got in and got a shot. Much, much better after that.

After trading emails and PM's with Jay for the last week at Justbent Technology in Phoenix, Arizona Jay has come up with these 3D renderings of the redesigned hopper and chute. Jay took my crude drawing and with many measurements passed between us Jay arrived with plans to make this new hopper that will fit like a glove. I have yet to meet Jay but will be traveling up to his shop and onto the GPAA Expo on Saturday Jan. 18th. I have decided to Powder Coat the trommel frame and maybe Cadmium Plating of the cylinder as the metal plating will not interfere but very little the 1/2" hole diameter of the 1434 holes. Powder Coating will impact the hole diameter.

If anyone is in need of any metal work I strongly suggest that you contact Jay at Justbent Technology as he has the equipment and the skills to turn your idea into reality.

I like it as long as you're careful feeding it. You may want to think about adding an elevated back stop around the top of it to keep from throwing dirt past the hopper opening when shoveling from a pile.

Something you could always easily add on if you ever saw the need to.

Great looking design on the hopper. I would suggest extending the frame under the hopper far enough to sit a bucket on just behind the hopper.

Stan, good minds think alike. I am going to make a removable frame but this frame will have a tilting device with a handle so that the bucket can be easily put in place, pull the handle to dump the contents of the bucket into the hopper. It needs to be removable so that we can shovel directly into the hopper if needed. Just thinking ahead because of my shoulder. I can still lift with the left arm...

Maybe a heavy sheet of rubber hanging from the frame
 

Looks good Keith. Dump system for the bucket is a great plan. I've thought about adding one to ours too. Just do not have a fab facility nearby I can use.
 

Here is an interesting fact. The cylinder hole layout consisted of 1434 holes. I center punch all 1434 holes first to mark the cylinder. Next I drilled 1434 holes using a self centering 3/32" drill bit. I then used a step drill bit that had 13 steps ranging from 1/8" to 1/2". So technically I drilled 14 holes at each center punch for a total of 20,076 holes.
 

Bored..... I get it :icon_thumright:
 

So Keith, now you're making a bucket dump?
Got a question. What's going to hold bucket in place? Assuming only one person is operating. I'm guessing your turning handle/lever with bad shoulder arm and holding bucket with good arm.
Maybe putting two 2-3" lips on each side, do it keeps from sliding in.
I was talking to a guy about making a small belt loader to take to the hopper. That way dirt and bucket stays low. Or if a wheel barrel is being used to move material. It could slowly get dumped or shoveled onto it.
The only drawback I think is its one more thing to go bad in the field, but then back to bucket dump again.
I think with all this time you've got now, you'll figure a way to get it dug, dumped, tromelled, sluiced, and panned (or divert cons to a shaker table). That means self cleaning mats.
Put mats on angle so cons go to a channel and put on shaker table.
Just go home with gold.
Then there's the self cleaning tubs for the sludge.
Can we get them to be like a toilet? Flush out sludge and tub refills with clean water. Lol

The bucket would slide into a three sided bracket made of 2" wide steel strap that has a pivot point on each side with the handle facing the user. Once the bucket is in place a spring would stretch around the back side of the bucket securing the bucket in this bracket. The spring would be a quick connect / disconnect allowing the empty bucket to be removed and a new bucket installed quickly. There are other methods of securing the bucket by placing a turn tab that applies pressure to the top of the bucket but I believe the spring will work very easily and quickly.

As for the sludge the biggest part of the sludge will be retained in buckets within the trough that will need to be change out as they fill. Now in regards to keeping the water clean the use of a small scale Lamella Clarifier made from old Master Cool pads will be used. These pads when properly position will trap solid particles that begins to settle onto the pads due to the angle where the solids will not travel uphill.

A conveyor system can easily be made with a hopper. Rubber conveyor belts can be picked up on eBay rather cheaply. To drive the conveyor belt a hydraulic water driven motor could be used. Many options are available just finding what works best is what counts.

If I had to do it again I would differently look at rotating the trommel from a hydraulic water driven motor due to having a pump already on site. One less gas powered motor...

Do you think you could design a water driven vibration system? I've looked a little and only found pulsating shower heads. I too want to illuminate another kind if motor, gas or battery.

I think its a very good possibility. Let me think about it and I will email you. Something that comes to mine is hydraulic water driven motor rotating with adjustable counterweight that you could adjust the amount of vibration... You can also control the flow for the amount of vibration.
