OK speedy. If you can make it, the beer's on me. You've got some nice innovations on your sub, and I'm looking forward to seeing it. I'm welding the window and hatch frames in right now, and waiting on Greg to finalize the plexiglass disks. Should be doing the FPR for the rear fairing soon, and then continue with the front end.
Are you going to have any kind of heater on your sub ? The water temp here is 54F to 57F and I'm anticipating fogging on the windows. Hopefully the re-circ fan will prevent it, but I may be looking for a heater solution later. I wonder if an air dryer would be of any use.
Another thought I had was using a vacuum pump to test the hull integrity. At some point I'll be sending the sub down empty on remote control, but maybe pulling a vacuum on the hull would be of some use before then. Anyway, better get back to the shop. See ya later, Frank D.
