    Ok, how many people use hand pumps? How many use scuba tanks? How many use both? I though that I had this covered but fate interveened and I’m back to the drawing board.

    Thanks for the feedback in advance. And I do have a sense of humor, so let her rip!

    I use a scuba tank and have a FX pump too for field backup but man is it tough to use. So I would say use a tank way more enjoyable for sure.

    It took 2, 5 minute fill sessions to go from empty to 2800psi with the pump, then after shooting for a while it took less than a session to go from 2000psi to 3000psi.

    More shots and again from 2000psi it only took a few minutes…

    The pump is acceptable but when you get above 2500 it gets a bit harder to push down, but I don’t mind, since shooting is SO much fun…

    I would imagine a tank would be far easier but then your carrying around the tank to refill after shooting…

    I’ll be getting a tank here when the scuba shop has its yearly sale…!!!

    martin, now thats some good old fashion Okie engineering, I love shit like that, it’s almost as if the yard just gave berth to it.
    How fast dose it do its thing, and dose the pump get too hot?

    It does 1 stroke/2sec. in 2nd gear–just right! I grabbed 5th once and had to chase that 5.5HP gas bastard down to kill it :mrgreen: –WAY too violent!

    Yea that FX pump gets a little hot near 2500PSI and I let it cool a bit before finishing to 3000!

    Too lazy to pump, and too much hassle getting scuba tanks filled, so I fill from a 4500 psi, 443 cu. ft. industrial nitrogen cylinder. Not real portable, but damn, that tank lasts a long time! Later.

    I use my CF tank mainly for my big bores… too much pumping for them. I normally use a hand pump unless I am on an extended shooting session.

    With the Talon/Condor… I use the CF tank at first… way too much pumping from empty. I’ll top them off by hand though.

    Crike! That oakie pump is great! Now that is good ol’ yankee ingenuity! My friend asked me if I could automate a hand pump. I told him that anything is possible. But that was not what I had in mind at all. I had envisioned something that used either air cylinders or hydraulic cylinders to move the pump handle up and down. Similar to a log splitter design.

    Sometimes I think that I am asking a really dumd question only to find out others have had the same questions and solved them brillantly. Hat’s off to you Martrin!

    So which pump? I have gotten the idea that the AF pump is a little easier but not as efficient. And that other more efficient pumps are much more dificult to operate.

    Thanks

    Nice machine there Martin… 😯

    Steve – I had the FX pump but I sold it when I got a 4350psi tank. I got a Hill Pump a few months ago.

    The Hill pump is more efficent but you really pay for it in pumping effort. I’d prefer to take a few minutes longer pumping FX than kicking my own ass pumping the Hill a few times if it wasnt for the fact theres next to no support for the FX pumps if something breaks.
