    Been folowing this for a while. I am really glad to see that you tested at a reasonable depth before declaring your box water tight. Electrical boxes are notorious for not sealing properly. Really happy to see that you got it working. Good job!

    I think an important aspect was the time I took sanding the top edge of the box to get it as smooth as possible. Straight from the store no way this box would have kept the water out.

    Box wiring progresses.

    Want some free 10 gauge tinned cable? Check out the lead acid battery pile next time your at the recycle center. Chances are there will be some computer UPS battery packs with the harnesses still on them.

    I'm trying a couple of layers of fiberglass drywall tape as a debris shield on the motors. The tape was smeared with a layer of E6000 to keep it in place.

    Looks like it should work. Good idea.

    Well I'm signed up for the battle so I guess I should make an effort! ;-)

    Been working on the Barham when I can. Controls are almost done. Today I finished up the prop shafts and started on the rudders.

    Way too much shaft between the stuff tube and universal joint, wiggle wiggle is never good.

    Look again Carl. No universal joint. I went through great effort to perfectly align the shafting and motor. It's one solid connection from motor armature to prop.

    Sorry Steve, I didn't see the perfection, great job.

    Probably not that perfect. I didn't have the shaft alignment rig I had access too back in the old Nav days. Used to be pretty good aligning multi-ton electric motor and pump units to under a thousandths or so (in three dimensions).

    Some rudder work done this morning.


    3.75 square inches of fiberglass sheet gets bonded to the rudder posts.

    Then the posts get sandwiched with another sheet and epoxy putty.

    Think I'm going to call these X-15's for obvious reasons.

    Interesting rudder design. They are clearly optimized for turning while going forwards. Will be interesed to see how they perform in reverse...

    I don't think most ships turn well in reverse regardless of the rudder design given that our ships rely on thrust vectoring of the water flow

    So true. Learned that when I was learning to drive a single prop, single rudder boat. Turning in reverse requires skillful use of bursts of forward thrust and rudder.
