  • All my hair fell through.
This is a two man hand dredge that I patterned after a man driven irrigation pump. Sand gets pulled into the catch bucket quickly. One man stands on the plank and pulls/pushes the lever, and the sniper directs the nozzle. I made this from plastic planks, sewer pipe, and swimming pool parts for the most part. The only things made in the machine shop are the pistons in the pump,  I machined the ends of the aluminum rods in the frame, and I slotted the lever arm where the piston rod bearings ride in it. [ Invalid Attachment ]  [ Invalid Attachment ]

The filter is just an old cotton sock to keep the sand in the bucket and out of the pump. The catch bucket is an oil bucket with a rubber o-ring seal in it to hold vacuum. The gray plastic bucket bottom fits inside the catch bucket to keep it from collapsing under vacuum (happens when the hose plugs up). [ Invalid Attachment ]

Currently the pump uses standard hydraulic piston seals, but I am going to change it over to foam seals, and use a white PVC pump barrel instead of the black ABS sewer pipe. The black is lighter, but the inner surface is very wavy and not so durable. [ Invalid Attachment ]  

I made this before I got a sucker syringe made.I usually use the sucker, but the two man unit holds a lot more sand, and it really moves it fast. I will post updates and changes as I make them.
Naps are wasted on toddlers, only an adult can appreciate them. Looking for mine now.

I forgot specs, well not really, but trying to post something large and losing it breaks my heart.
Pump bore- 3" stroke 6"  That combination moves enough volume to completely purge the inlet hose with a 15% margin

I am going to tear the unit down in the next few days, and will exactly dimension individual parts if there is interest. Let me know.

You probably know how it is, but one thing pushes out another. I am in the middle of another fairly involved engineering project, hence I have not had time to pull this unit down and retro fit or dimension it. I still intend to do it, but it must wait a little while longer. Apologies.
