    The pump mount is sorted out. The pump will get wire-tied to that side support. The three washers glued to the bilge hold the bottom of the pump in place.

    UPDATE: Thread on this pump

    The bottom plate of the pump was trimmed down and channels added to improve water flow.

    Now that the pump is placed I can finish up the water channeling in the aft end.

    Till next time...

    Steve,
    No issue with the outlet being off center? I know on mine when the pump was under load it would tend to submerge the outlet under water.

    Steve isn't figuring on pumping enough water for that be an issue. No holes - no water - no pressure, right Steve? ;)

    I don't know. This is basically the same setup I have in my Mogador and I haven't noticed that issue. If it is a problem, I'll put a deflector over the outlet directing the stream aft. This was the simplest mounting solution so I went with it.

    You have discerned my strategy. Using the lighting quick reflexes of youth, I will teach my grandson to drive around, over, under, and in-between any and all bb paths's, thus avoiding holes in the hull. I don't know why I even bothered to put a pump in this thing? :woot:

    Yes, that's a very good strategy! No bbs will get you down there. No pump needed either! :laugh:

    Back to cutting foam water channeling.


    The pump sump is done...

    upload_2017-12-11_5-12-26.png


    ... and shaft alley is complete. FYI, a course rat-tail file cuts nice grooves in this yoga block foam.

    upload_2017-12-11_5-12-46.png


    The channeling further aft will have to wait until I get the cannons sorted out. Now I'm onto controls and wiring.

    Thought I'd do a schematic for once...

    Don't the BC firing boards have the diodes already in them?
    I really like the Polulu boards, they're dirt cheap and they have the diode built in.

    Newest ones do but the older ones do not.

    I'm using the BC XR-4D board. It does not have onboard diodes. The Pololu boards are nice, I use one in the Mogador, but they don't have a dual-on-one-channel solution.

    I think you are convincing me to switch to 24V. What solenoids are you using for 24V operation?

    Welcome to the dark side! ;)

    In the Barham I'm running 12v Kip's ate 24v. Working great so far. For this build, I just picked up some Spartan 24V valves to fool around with. I have extra 12v coils that I may swap out with. Need to see which coils fire with greater authority at 24v.

    upload_2017-12-12_9-27-23.png


    FYI, almost all of the Spartan valves are available off the shelf in 24v at USPlastics.com. Though their only 1.5mm orifice but I think they can be enlarged easily enough. Stay tuned on that project.

    Started on the cannons. This is going to be an interesting installation.
