Charging a PCP

[jmorris]

Does anyone have information on building a shoebox style compressor?

I have thought about automating a manual pump with timers for duty cycle but thought I might see what information others may have found.

FX (i think) had a sytem for using their handpump with power.

Not answering your post. But I was thinking of getting a HP 150CF tank - nitrogen or air. Cost for the tank is $235 (buy) + $16 fill.

Over 200-300 fills, depending on fill/residual pressures.

I am fortunate to have an industrial supply and a SCUBA shop in town. And lucky to buy a cheap HP regulator.

I went ahead bit the bullet and bought a shoebox. It was some cash up front but in the end am very happy with it. It just doesn't fill a 550 CID tank in much of a hurry.

But it does get the job done, and I am quite happy to be free of dealing with dive shops.

I like to build stuff and have argon and co2 in bulk tanks and this caught my attention.

a lot less machine work and looks promising.

I have the shoe box as well at the cost to build something like it you might end up spending more and getting less. They are slow but run like a clock.

Yes, it does get the job done. The primary reason I bought it was to be free from dealing with dive shops and as stand alone as possible. I could justify it quite easily as the nearest shop is a 50 mile round trip and can't be done easily with the hours I keep. My best guess is with running the shoebox and my shop compressor as a first stage each fill cost me about a buck in electricity. It takes me around 3 hours to fill my bottle from 3000 to 4000 PSI, this is close to 2 weeks of bird shooting for a buddy and myself (he shoots an AT44 in .22). I do recommend you buy yourself an inline air dryer.

Off the top of my head I can't think of any other guns owned here that get shot as much or get as much fun for the dime as these PCPs. If you shoot more than 2 tins a month you'll be glad you bought your own compressor in no time.

"I do recommend you buy yourself an inline air dryer."

Absolutely! If you don't use something to filter the moisture out, the inside of your beautiful PCP's will be a mess in no time at all.

Excellent advice, I couldn't agree more.

Thanks guys, I wound up making a booster pump and will give it a full test next week when my 4500 psi tanks, fittings and rifle get here.

I tested it up to 4000 psi so far and only have $18 and an hour of time in it so far, looks promising.

In the homemade booster pump thread I started a week or so after this one.
