    A little project I have been working on for the last couple months from a bunch of parts and pieces i had laying around

    early tests seem good

    A little more explanation may be necessary for some…  like me!  (grin)

    OK, I will assume this is a device to boost PSI from tanks that are nearly depleted… right?

    Very cool!  I'd love to see the assembly and internals.  Challenges?

    I have a ready supply of low pressure nitrogen (3000 psi) and building this should fill my guns and my guppy tank .. with less than a 200.00 bucks in it im excited to be able to use nitrogen

    Looks like an Altaros or Rocket booster PCP booster.

    Ti's but it's homemade, what's not to like 🙂

    It will use a shop compressor for work on the main piston from the controller on the right.

    The gas (air/N2/H2) supplied to the HP piston is boosted to any pressure desired.

    So how much have you got done on this? I want to see more!

    Well my calculations were a little off !  I used a 6" drive cylinder and a 1 1/4 driven cylinder with 300 psi of nitrogen on the input. of the driven cylinder and using 170 psi on the drive cylinder it stalls at  2500 psi i !! Im going to sleeve the driven down to 1" and see what happens

    I guess you cannot raise the pressure of the drive cylinder any more?

    Past 170psi is a hard bargain on a standard shop compressor!

    Sorry I assumed that ready supply meant unlimited supply of 3000 psi nitrogen. That way one could use that,  regulated down to drive the drive cylinder.

    I am making a sleeve  and a new piston to make the high pressure bore from 1.250 to 1.00!  I am going to loose volume BUT should be able push the 1.00 piston!

    Not that it is a easy thing to do but if it works you could always make a longer stroke.

    I would need a longer low pressure cylinder then! The dimensions were kind of an educated guess and i was pretty happy with the results! Its not a big deal to sleeve it down
