What's wrong with PVC? I prefer to machine things out of billet aluminum too, but for just a "keep in car cannon" Or make a small one running on high pressure. . Thats was my little golfball gun was, 30" barrel 3.25" chamber coaxial made from alumnium, I pressursized it with a tank of Co2 with a 40...

You could use the roof rack but that might be a bit odd. Dont have a roof rack. I was thinking about small coaxial since that what my little golfball gun was. But I dont want to make another copy of it it was too much machining and I hate welding aluminum. Nice instructable! Thanks, I hope I win, b...

There is also Alumnium SCBA tanks, I have one on my rig at work. If its out of hydro, you may be able to have it convertered to C02 service. I remember the guy that refills my tanks said something about that he could rehydro a fiberglass tank for Co2 since its only 900max psi vs 2500+ psi. I'll chec...

I just finished my latest instructable, for a onboard air compressor (now I just need to rebuild my little golfball gun RIP buddy :cry: ) Any body see anything I should of added? http://www.instructables.com/id/On_Board_Air_Compressor_Welder_for_vehicles/ Yes I know the videos are horribly boring, a...

The jeep had 127hp(its a 4banger) I really want to swap in the OM647 from a sprinter van.

Well I finally finished my OnBoard Air compressor for my jeep, so I can get some off road spudding in. Its a old mopar RV2 AC compressor from a 71' dodge dart, the pressure switch runs it 110-145psi with a 4.5gallon tank under the jeep, and 165psi popoff, with two quick discos under the hood and one...

I'm pretty sure the gauge part will measure pressures above 160 its just most air compressor dont go higher than 150psi, or I should say are limited to 150psi. I'll test it with my C02 rig.

I was out at harbor freight and saw they have this little digital PSI/flow gauge for about $15, its attached to a small regulator I was looking at it and it seems to be threaded onto the regulator with a 1/8npt. I'm going to pick up up today to use with my the 4" coaxial golfball gun I'm building. A...

Seeing multiple versions of a homemade chronograph I might as well post my idea. The usually homemade chrono uses two microphones and paper or metal targets, the targets have to be spaced correctly usually a 6 to 20 feet part and the microphones might pick noices for valves opening and you have to p...

I would mix fiberglass epoxy and sand 50/50% that would dry inside a ping-pong ball easily, its what I do. I never thought of candle dunking one to take up the extra diameter.

I'm not saying that he isn't a good mechanic, it just the way he stated it previously. And the compressors themselves aren't modified, just whats attached to them, a tank, pressure/safety switch, and fittings etc. Example for just pumping air/filling tires/spudguns no airtool, I would (lets say I ha...

In your 'machanical years' wow! I like how you assume that the system is limited to 30psi and it can only run for a second. Here I'll give you some links, to try to correct your 'machanical' knowledge on the subjuct. http://www.jedi.com/obiwan/jeep/yorkair.html http://www.huv.com/jon/jeep/Air/index....

The only reason AC compressors get high pressures in cars is because they are pumping oil/free-aun(sp). They arnt very good at pumping air, it would take a long time to pump up even a tire with one. In that you are wrong, you just add a oiler to the intake on a sanden, (york210/rv2 have a oil sump)...

Shades of dyslexia

Does your car have AC? and do you use the AC/defrost? If you have AC and dont use it you can convert it to compress air, go onto google and search for onboard air sanden (your call will most likely have a sanden rotary compressor) I have a RV2 AC compressor in place of my stock AC for running airtoo...
