So you dug post holes with a shop vac? Is it sandy where you are? I feel like I hit about 10,000 rocks per post hole. Many too big for a vac hose, and many just big enough to clog it.
I might have to try it anyway.

Toting a generator isnt really an option. I also just have a shop vac hose, if theres moisture the dirt collects on the sides with a shop vac and loses lift. That's how I've always dug post holes.

I have seen guys do that and it worked OK. Air powered vacuum producers work but I don’t know how well. Sometimes they are called eductors or ejectors.

I'm a broke joke, so hydrovac isnt in my budget. Besides, I want dry spoils to put back in the hole. This revision works for venturi. I have multiple size reducer but right now I'm just doing 3/4 to to inch. The 3/4 to 1 then 1 to half back to 1.5 for the venturi side seemed to have the best lift, but the hardware store didnt have everything, so it's all in 2 inch right now I'll dump to a 2000lb peanut sack if I can find one, but for now I'll just use a 30 gallon drum and dump on the mega movers. This is for use in conjunction with the airspade I did have some coin to get. Venturi math gets complicated and I'm full retard so I need to find he best ways to increase negative pressure and where to drill the ports. I also wonder if theres an option to recapture the exhaust into the airspade. I need you nerds to go full geek. If I can get valves correct I'll have the local machinist make me a couple that are pressure rated. This is to mimic the airvac I also cant afford. This proof of concept has the lift to clear potholes and handholes, but I need to clean it up and get more efficiency. A side discovery is that this setup is perfect for blowing straw and seed with glue _____ -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
