How to make a mini power washer?

My friend has some Traxxas RC Cars. One is an electric one that is water proof. He was talking to me one day about making a mini pressure washer to clean it. He is thinking about running it off a hose. He wants to basically use an mechanical pencil tip that you can screw off. Do you know if it will work, or blow the tip apart? or too much pressure. I think it would be too much pressure, but tell me what you think. If we make it, i will post it.

Just a warning about a new epa rule: when you are using a preasure washer, you have to collect all the water, and dispose of it properly. There are some pretty heafty fines if you don't. I think there are exceptions, but I don't know them off the top of my head. The only reason I even know about it is that my Dad is a contractor, and he was complaining when that regulation came out. If he doesn't follow it, he gets his truck, tools, and ability to work taken away in addition to the regular fines.

All we where going to use it for was for removing dirt and mud
It is because of the paint... so I really don't know. I would say you have a good chance of getting away with it since it's so little. (Just wanted to throw that out there.) ;)

It's not the paint, it's general waste-water, and as you say in large enough quantities.

Um... look under lead removal... it's got something to do with the possibility of lead in the paint. (Maybe it's just in IL, but I thought it was nation wide.)

Automotive paint last had lead in it when?

Like I said, I don't really know about the epa rules. I'm just giving a warning about something I heard, because the fines are pretty hefty. It's up to you to do the research, and decide if you want to proceed or not.

...And I don't think it's a problem for real cars... after all, I don't want to power wash my car... do you?

Just use the hose.

ya but that thing was, we wanted to get into the smallest cracks and get all the mud out and have control over somethings instead of running back to the hose everytime

I'd say that a ~4mm (inner) diameter nozzle would be good enough, you'll not get enough flow out of the pencil-tip.
