    Check valve -> accumulator -> solenoid -> cannon. In case you weren't sure.

    Float test done and double checked. Going by the plans would have definitely made my windows too low by about 5/8"!!

    Need confirmation on my cut marking so I can start covering myself in dust. Thinking about staggering spacing between the first 4 in the bow a bit to close up the window before the 3/8" rib.

    Drop the stringer to the area of the bulge itself. If you change that 3/8 to a 1/4 and strip 1/8 of the bow you get another rib. Up to you.

    Ah good call. Wasn't sure on the position of the stringer. Going by the Strike instructions, this is where it shows to put it. I also hadn't considered taking area from the bow.

    Stringers are there so you can sheet over bulges and whatnot so they've got to be where the feature that justifies them is. I also like them out at the wider spots of bulges because that's where you're likely to get ram damage if you do get hit and it helps to have not such a huge hole. It's not so much a problem on a cruiser, but why invite disaster ;)

    Got the stringer and first ribs shifted around a bit. Think I'm happy with this layout.

    Plumbing the cannons I realized I didn't know if the required 10-32 test port is male or female? Trying to come up with something that mates to a 1/4 PTC fitting.

    Option #1. 2x "Y" Adapters (290 psi)
    [​IMG]

    Option #2. 3 port Manifold (only rated for 145psi) "T" fitting would be used for pressure test port
    [​IMG]

    Option #3. 4 port manifold (also 145psi) Test port straight into PTC fitting
    [​IMG]

    Waiting on the 1/4" union PTC check valves to show up that I ordered from Mettleair.

    Trying my hardest to make this thing ready for battle or even testing in Saranac by the 23rd......think I underestimated all the small obstacles. I ordered up a new fancy milling machine today so that should overcomplicate all my installs nicely haha!

    The requirement for a 10-32 test port should be considered for a rule change. It would be much easier and quicker to plum the test equipment to a quick release.
    Just saying......

    Just get a ptc to 10-32 female fitting (and plug it when not testing with a 10-32 screw and rubber o-ring).

    Otherwise you'll just get the test rig hooked right up to your regulator. That's what they did for me when I didn't have the pressure test fitting.

    My suggestion.. based on those prices.. .is find a local parker distributor. The parker stuff is so much less expensive than McMaster Carr.

    I use Huffco here in Houston.

    Just as easy for YOU to make the adapter to 10/32 female. CD's have plenty of "special" things to do. That is why there are standards to the test requirements, so that you make the CD's job easy.

    Even buying from Clippard is a lot cheaper per unit, mind you they want you to buy 10. But those McMaster prices are rediculous.

    I find a place, in-line, to put a Needle valve or a poppet valve.
    Then you screw the gauge into the relief port
    I can also use this to bleed my line to change CO2 bottles between sorties

    Drill and tap a 10-32 hole in the end of the option 2 or 3 fittings and you're good to go!

    My local Parker dealer is only there to serve Caterpillar's needs. Unless you're ordering 500 of something, they won't even bother talking to you.
    Didn't see an option to order the particular 10-32 to 1/4 PTC adapter on Clippard.

    Thanks for the help gents. Always appreciated. Worst case I'll have a triple stern shore battery for Saranac haha!
