Home made pressure washer?

[NH Jeep Junkie]

Has anyone made a pressure washer with a water hose and an air compressor? I want to try it but I don't know if its been done before or not. I searched but didn't find any info. If you got pics please post 'em
Thanks,
Mike

Not worth the effort. You can pick up an inexpensive one at Wal-Mart. I have this bottom end one:

I got it on sale for $79. It does an acceptable job.

I think the air pressure would just atomize the water. Like a paint gun does.

Staun, the aussie company which is known for its tire deflators, makes something similar to what you're referring to. It's called the massojet (http://www.staunproducts.com/masso_air.php) (<--click).

You may be able to mimic it, my guess is that the nozzle part would be the trickiest?

I first saw this thing in a peterson's article a couple(?) years ago. I have not been able to find any pricing info, retailer names, or any other information useful in acquiring one. I'm a poor college kid so I just save up my quarters.

Don't waste your time. 175PSI of air isn't gonna move the water like a pressure washer does.

Best to do is keep your eyes peeled in your local trader/recycler/etc, get a gas powered model, at least 2500PSI @ 3.5gpm.

I splurged and got a 3700PSI @ 4.0gpm Honda powered beast (11HP I think?). Biggest model Home Despot had. 1k$.

I've made several home-made air-powered sprayers - and they do some things to an extent, but they are not pressure washers by any sense of the word.

Instead, I generally use mine for spraying solvent in order to clean motor parts, etc.

Easist way to make one is to just make a simple siphon nozzle on the front of an air gun. I have used something as simple as a T fitting that I threaded on the nose of the fitting (with a drilled orfice to control the amount of siphoned liquid) to a machined part with a venturi. Neither one worked any better than the one you can buy already made for under $10 - but I used what I had laying around.

Thanks for all the input. I'm not planning to peel the paint off the walls just looking for something to add a little oomph to my hose now. I like the ideas. Thanks.
