    I don't usually document regulator builds but this one deserves it's own thread. It might also be helpful to those of you out there thinking about building something nicer that what's currently available in the aquarium trade. I'm also not much for documentation so bare with me.


    This build will use a new Airgas Y12-215B

    Moving along, here's inside the din connecter for the Burkert solenoid where I needed to connect the power cable.

    Power cable wired up.

    Plugged it in to make sure it works. lol

    That's it for now. Someone in China sent me the wrong bubble counter. I'll post a completed photo after the right parts arrive.

    Parts list (used above) :

    - Airgas Y12-215B
    - SS Smith cga-320 nut/nipple
    - SS Burkert 6011 w/varistor and LED
    - Ideal V54-1-12
    - Swagelok SS-4-HRN-2
    - Swagelok SS-2-SE (2)
    - Swagelok SS-2-HN
    - Parker 2M-C4L-1/3-SS
    - Stolen computer power cable

    I hope you enjoyed the build as much as I did! It's driving me nuts not testing it out yet...

    Thanks guys. It was a fun build. I'm really impressed with how the Swagelok parts assemble.

    I see you used two street elbows instead of one street elbow and one male elbow. Any reason for that decision? Looks good.

    ^ I was trying to keep the whole post body as close to the regulator as I could. When I tried the male elbow I only ended up with about an 1/8" clearance between the bubble counter and the low pressure gauge. The extra piece just keeps the bubble counter from being right next to the gauge. If I didn't have the bubble counter there I would have used the male elbow.

    That's a great build! Are you going to send your BC to chromemasters to get it chrome plated?

    Ya know, it never really crossed my mind. I knew it would stick out. The build was already costing a lot and taking a long time. I guess it's never too late to have it nickle plated though. I just learned how. I think nickle plating would look better. Chrome is just too shiny - lol (sorry - I'm not really a chrome guy...)

    I think chromemasters does nickel, chrome, and some other finishes...
    I had two JBJs chromed there. Very fair prices.

    solenoid was about $103 shipped
    v54-1-12 was around $130 shipped
    I'm having a hard time remembering how much the swagelok parts where, probably around $50ish shipped (you can always look them up on their site)
    the check valve will cost between $25-$70
    bubble counter cost about $25
    you'll see 2-stage regs for anywhere between $50-$250+ (this one was new)
    the stainless cga-320 nut and nipple was about $50 shipped

    Thanks guys. What sucks is that the guy I built if for is still waiting for his 120p to arrive. It hasn't even been used yet. All that shiny just sitting there waiting.
