Battery Compartment #1

Here's the start of the battery compartment.

Fig. 1.  The front is all cleared except for the forward left & right trim tank water valves.  They'll need to remain because the battery holder can't go too close to them.

Fig. 2.  I cut some 20 mm x 20 mm x 3 mm angle bar for the batteries to sit on.  Here I'm setting them in place to see where the best position is to get the batteries in & out easily.  Having said that, they won't need to come out unless they need replacing.  They will be able to be charge via a mains plug in the conning tower.

Fig. 3.  The two rails with their threaded ends that will be welded to the hull interior.  Each rail will be bolted down separately and can be removed if needed.

Fig. 4.  A cardboard mock-up of the battery.  I'll use this as something to test out the position of the rails inside the sub, rather than trying to lift a 20 kg battery in and out every time it needs a test.

Fig. 5.  I've cut two pieces of wood at 31 cm each and clamped them at right angles to the rails.  They are square to each other and the rails.  It's now ready to go into the sub and be tailed to fit the hull and forward dome.

Next I'll be welding it in.
