Part 3b - Watertight container (continued)

Instead of duplicating the steps necessary to complete the clear lid for this WTC, I´ll simply refer you to Propulsion - Watertight Container (continued) page as the steps are identical.

Here, you can see the finished product less the silicone o-ring gasket I´ll manufacture later on.
I´ve included this pic so you can see that I did purchase an elbow for my inside pressure gauge. Wanting to reduce the amount of air-space inside the WTC, I lowered the height of the box and placed the gauge on an angle. I´ll still be able to read it however.
You can see that things are getting a little crowded as construction continues on the WTC.

Here, I´ve installed the receiver, two (2) expansion modules, the Missing Pulse Failsafe (AFS), the Battery Eliminator/Voltage Regulator (BE/VR), the bow planes servo, the bilge pump and the water sensor. And, there´s more to come.
Another view if the WTC showing where the forward battery will be located. The next step will be to start drilling holes for the pneumatic tubing and the waterproof conduit.
Routing the neoprene hoses (from the CO2 bottle to the manifold ... and from the Clippard valves to the Clippard actuators) required drilling eleven (11) holes in the aft bulkhead of the WTC.

I used a 1/8" drill bit for the holes, and I used 5/32" brass tubing for a tight fit through the bulkhead. The neoprene hose fits perfectly over the tubing about ¼" on each side. Additionally, I put a silicone seal on the outside of the bulkhead where the tubing enters the box.

To the right of the brass tubing, you can see that I´ve also drilled a hole and installed one end of the PVC conduit connector. The four (4) servo extensions (both Electronic Speed Controllers (ESC's), rudder and stern planes) exit the WTC here, and will pass through the conduit before entering the aft WTC.
The forward WTC is almost complete now. Notice the small piece of brass tubing on the right side of the WTC in this pic. That is the exit for the bilge pump. The hose from the pump is routed underneath the electronics board and out the side via this tubing. If you remember, I´ve also installed an in-line check valve to prohibit water from re-entering the WTC.

The next steps will be to route the receiver antenna outside the WTC, cut off the battery terminal poles and also figure out what to do with the bilge pump light.

Is this submarine going to be powerful, or what? How many subs have you seen with a ten (10) cylinder engine and an exhaust manifold that looks like that? Just kidding!
