For a reservoir you could use an old propane tank. Some people have those ones that went on recall or something lying around.

it works now i can get it up too 300 psi right now
it takes forever to prewssurize the resivor though
3 20 ft lengths linked together with air hose bolted to the ceiling

and it cost less than $20 dollars for me to build it

300psi sounds interesting but plizz post some pics and give more details

1. when you said that you can take it up to 300psi - you mean that it goes to 300psi or beyond that?

2. how did you managed to take an air compressor to 300 psi ?

3. is the pump capable of taking such pressures ?

4. Are you planning to add a pop off valve or pressure switch to it ?

5. what's the size of air reservoir ?

I hope you are taking all safety precautions... air pressure is something quite dangerous you know...

Forget about them... sooner or later it will break down... try building a fridge compressor if you can get a pump, consider building a homemade stirrup pump or buy a regular shop compressor...

I have had no problems with it. I use it to 150 psi all the time. I just dont like the flow rate.

...mine broke after two weeks.. quite a lot of people here has similar experience with them...

I don't think that there is any practical way to increase the flow... of course you can always buy 10 such compressors but I feel that you'll soon discover that they are no good
