Generally anodising will add thickness. Half goes into the metal and half goes on the outside. Depending on the clearance or fit of your threads depends whether you have a problem We anodise but have to allow for clearance.. The Anodisers I have available are very commercial and we have had issues affecting O’ring sealing so pick your anodiser carefully. On a class 3 thread fit you cannot get complacent as 50 microns thickness is still 0.002” so a thread will have a much greater effect While 50 microns is only 25 microns increase it means 100 microns on clearance diameter if both male and female are anodised.. There are some new processes which claim will not add thickness such as diamondysing but that process is added ontop of normal anodising. I would ask Emile what actual process his anodiser uses. We would need to go to an aircraft certified anodiser. We do our own hard anodising. Pulse anodising will produce better results.

My experience is that PSUB stuff gets banged around a lot so addeded thinckness and hardness that comes from Mil-A-8625 type III seems to work out better. Most of my marine experience has been in fresh water lakes so we really need to get someone with a lot of saltwater experience to chime in. Also most psubbers don't leave their boats in the water all the time and rinse off the boat after use.

Get your wife to take the video of your hand waving. We would all appreciate the entailment value! It a lot of fun to bench test components being operated by PLC and see them come to life based on your code. As to compass heading, roll, pitch and yaw sensor, I use the Ocean-server <a href="http://www.ocean-server.com/compass.html" target="_blank" rel="nofollow" shape="rect">http://www.ocean-server.com/compass.html</a> OS5000-S Solid State tilt compensagted 3 axes digital compass, This is a RS-232 serial device. You have to write some PLC ladder logic code to parse the ASCII string sent to the PLC to extract the data, I packaged mine in a small 1-atm aluminum anadoized pod about the size of a tennis ball that I have mounted outside the steel pressure hull behind the pilot. Even though the DoMore CPU you are using has several serial input ports that could be used for this sensor, I ended up getted a dedicated coprocessor module that plugs into one of the AutomationDirect PLC bases that enables me to write the parsing code in BASIC and enables me to dedicate the coprocessor to this sensor. It took me a while to come up to speed on RS-232 comuncations but I now have this working petty much bullet proof. The coprocedssor then sends the heading, pitch, roll and yaw values to the PLC cpu to be used any way you want them. Currently, I am only using this data on my HMI.</span></div><h3><span lang="NL">Cliff</span></h3></div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;"> </span></div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;">On Fri, Feb 3, 2017 at 12:52 AM, David Colombo via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:</span></div><div><div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;">Hi Cliff,</span></div></div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;">Its been slow going as I am finishing building my home. Should be finished in 45 days. But I have been making progress as I learn PLC coding and ladder logic in the evenings. Currently I am working thru the flight Joy Stick switch controls combined with a 4 position joystick base to control the (2) forward canard wings, (2) vertical thrusters (2) horizontal thrusters, and (2) vectored rear thrusters to have a flight experience. I spend many hours in the evening when my wife is not looking waving my hands thru the air simulating flight and then coding the switches needed to make the maneuver. I'm sure it would be entertaining to record a video. I am curious, are you using any gyroscopic sensors for pitch and roll? I'm thinking I need to have some build into the coding so as to limit my human abilities as safety overrides. </span></div></div><div class="yiv7833930998MsoNormal" style="margin-bottom: 12pt;"><span lang="NL" style="font-size: 10pt;">The next step is to get a bench setup with the joystick and canard wings to run tests on the coding and for flight training purposes.

When I first installed life support on the R300, I had sensors distributed all over the boat. What I have move to is packaging all the Life Support related sensors in a single electrical box I call the AMOC module. AMOC is an acronym for Air Management and Oxygen Control. This made it easier to maintain the system and made it easy to bench test. I feed HP O2 from an external tank to this box. It in turn breaks the pressure and emits the O2 to keep the mole percent balanced. The PLC interfaces with the AMOC unit to monitor and control the air in the cabin. If you are interested, send me your email address to <a href="mailto:cliffordredus@sbcglobal.net" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:cliffordredus@sbcglobal.net">cliffordredus@sbcglobal.net</a> and I will send you the DCI for the drawings associated with the AMOC unit and the drawings. The axial flow scrubber I use is the same one Alec used for Snoopy. It has worked great. The PLC ladder logic code around the life support system is pretty straight forward. What I like about the system is that it automatically compensates for different sized humans in the boat but yet retains a manual mode in the event both the main and auxiliary power are lost. The assembly drawing for the AMOC unit details all the sensors as well as all the Swagelok fittings and circular disconnect. This unit should work well with the AutomationDirect DoMore CPU you have.</span></div></div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;"> </span></div></div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;">Cliff</span></div></div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;"> </span></div></div></div><div><div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;"> </span></div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;">On Thu, Feb 2, 2017 at 7:50 PM, David Colombo via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:</span></div><div><div class="yiv7833930998MsoNormal"><span lang="NL" style="font-size: 10pt;">Cliff, Thanks for answering the question I was just going to ask.
