Conning Tower Lights & Diving Planes

I've now finished the hubs on the both sides of the conning tower.  These will hold the LED lights and the diving planes.

Fig. #3.  I built the bracket, and the cover, for the 100 watt LED lights on the mill out of 6 mm thick perspex for now, later I will cut the cover out 3 mm thick scratch proof poly-carbonate.  Below the front part of the hub is ready to be welded.

Fig. #4.  The perspex bracket holding the LED in place.  The LED is bolted to the perspex and then the perspex to the steel by 3 mm bolts with a 3 mm high nylon spacer.

Fig. #5.  After much consideration I final found a way to weld the hub to the tower and get it square not only with the hull, but the hub on the other side as well.  The result was near perfect, except for a very small toe in at the front.

Fig. #9 & #10.  Both hubs are now fully welded together.  The diving planes are yet to be worked on, but I'm aiming for a pressure test by the end of this week so I may leave them for now.

For the rest of today I'll be working on new seals for the shafts.
