Tasks

Today is the first day of January 2017 so I decided I'd put together a list of things that are yet to be completed on the sub.  A list of the testing stages can be found here.

Red is not started.

Orange is underway.

Green is a compete.
Gray is not planned for initial launch.

• The hatch locking mechanism. (To be done after successful pressure tests)
• Drill holes in the aluminum heat-sinks for both the lights and some fans too. (08/01/2017)
• Wire up the voltage booster for the lights.
• Use the mill to cut the light covers out of 6mm scratch resistant poly-carbonate.
• Weld together the diving plane hubs on the side of the conning tower.
• Hatch seal.
• Weld together some locating pins so that the hatch is closed exactly right on the seal.
• Upgrade the current windows to 6mm thick poly-carbonate for pressure testing. (07/01/2017)
• Weld two handles to the top of the hatch dome and one handle to the inside. (11/01/2017)
• A periscope will be built into the hatch.
• Weld in remaining reinforcing rings to the conning tower.
• Water cooling system for the air compressor and the LED lights. (At the moment they are air cooled)
• Life support system.  This includes Co2 scrubbing, probably by passing air through soda-lime, and an oxygen tank, as well as a Co2 & O2 monitoring system.
• Buy Co2 & O2 sensors.
• Start buying parts for the trailer.
• The trailer.
• Pipe to seal the electrical cable for the submersible motor. (08/01/2017)
• Rubber buffers between all metal to metal points of contact on the outside of the hull.  (Made from 1mm or 2mm thick neoprene)
• Buy 1mm & 2mm rubber sheets.
• All paint must be striped of main hull. (28/01/2017)
• Strip paint of conning tower.
• The hull needs to be coated in the final color. (28/01/2017)
• Fill in various dents in the hull with car body filler. (These are small dents only)
• Ballast tanks need to be finished. (Mostly just the right side)
• Ballast tanks will be painted before being testing in stage two.
• The final windows need to be made from scratch resistant poly-carbonate.
• All final seals will be made from black Sikaflex-291.
• All welds double checked for integrity. (Included in stage one of testing) (10/01/2017)
• Make diving planes & elevators.
• Make diving plane hub and actuators.
• Make both the lower and upper dash boards.
• Wire in the electrical system.
• Make the throttle.
• Design the throttle control system.
• Make the throttle control system.
• Work on perfecting the float valves for all the ballast & trim tanks.
• Thread the shaft for the ballast release mechanism.
• Seal all water pipe thread joins with stag sealant. (11/01/2017)
• Test all solenoid valves.
• Buy sonar module.  (29/01/2017)
• A sonar system.
• Build the computer that will manage and control the diving & ascending. (I will probably use the Raspberry Pi 3)
• Last will be weighing the sub and calculating it's buoyancy before buying lead and molding then attaching the weights to make it neutrally buoyant.
