Additional content and files will be at: https://ko-fi.com/manmade Description: This is my design of a DIY hand dredge pump (see link below for original inspiration). The motivation behind this is that I wanted to make this more affordable. https://www.youtube.com/watch?v=QQFXjMorOO8&t=28s In the end this design cost me about $75, which is way less than the typical $175 options out there. BOM: For the pump and sluice tube I used 2"x36" pvc pipes. I made them extra long so I can get deep in a river if need be. For the handle and piston I used 1" diameter pvc pipes For the hose I used this part: https://www.lowes.com/pd/STAR-Water-Systems-Plastic-Hose/1000678131 You can get a good deal on a hose at walmart at this link: https://www.walmart.com/ip/LITTLE-GIANT-SPDK-Sump-Pump-Hose-Polyethylene-Dia-1-1-4-In/161323725?wmlspartner=wlpa&selectedSellerId=1122&adid=22222222227057768470&wl0=&wl1=g&wl2=c&wl3=161655850784&wl4=pla-267957687342&wl5=9029726&wl6=&wl7=&wl8=&wl9=pla&wl10=101593696&wl11=online&wl12=161323725&veh=sem&gclid=Cj0KCQjwgNXtBRC6ARIsAIPP7RvHMdxRhge0Xgw-2Cd2HcBwTBE2GDN-uDwRCRdzImdNSfE2JBcd_JYaAre_EALw_wcB For the rubber plunger I used the part in the next link, but I ground down the flange on the larger side to match the smaller side. https://www.lowes.com/pd/Oatey-PVC-Test-Plug-Fitting/3880609?cm_mmc=shp-_-c-_-prd-_-rpe-_-google-_-lia-_-142-_-indoordrainage-_-3880609-_-0&store_code=1080&gclid=Cj0KCQjwgNXtBRC6ARIsAIPP7RusIJhY-ffZf7GX8LS4AIkVfAruBfs8Up2tpoBtDr0Mrk5Gu9izdgEaAtB3EALw_wcB&gclsrc=aw.ds For the one way valves I used: https://www.homedepot.com/p/Water-Source-2-in-Plastic-Sewage-Check-Valve-SPC200/203449540?mtc=Shopping-B-F_Brand-G-Multi-NA-Multi-NA-Feed-PLA-NA-NA-Catchall_PLA&cm_mmc=Shopping-B-F_Brand-G-Multi-NA-Multi-NA-Feed-PLA-NA-NA-Catchall_PLA-71700000014585962-58700001236285396-92700010802552406&gclid=Cj0KCQjwgNXtBRC6ARIsAIPP7RtqMTx1Uy6xCuIKVzLtLnvz5jXkAhEOFApdJKNjtsaKo5jBvFQ46dEaAsmSEALw_wcB&gclsrc=aw.ds
