I ran everything by him and he asked Rick about it and Rick said that he didn't remember suggesting the macropoxy 650 as the best application for what we were doing but said that it could be tinted any color and are checking on weather the 650 is the best way to go for our application and weather a metallic can be added.

Another experiment: bought a cheap vintage car fluxgate compass. When I hold the sensor under the front MBT (previously I experimented with how high I had to hold it off the hull until I had this brain fart), against the inside "roof" of the fiberglass shell, it works perfectly, as in no distortion at all. I now know where to mount a future more accurate fluxgate sensor as it appears to be far enough away from the hull and the main brackets that mount the MBT to work as intended. I love easy solutions. I now see a way forward for a reliable means for nsvigation. Now as I am looking at used marine fluxgate compasses, it seems some of them are designed to feed an auto pilot. As I already have the parts to put an actuator on the rear thruster, all this has me thinking: an auto pilot for Harold. Set the compass and let the actuator compensate for the heading.

The rubber material is the same as used on a inflatable rib. The challenge is the configuration of the tube so as to not over inflate, change the shape, and warp the exoskeleton. While not to be used as main ballast tanks, but as additional lifting capability while on the surface to lift our front pilot higher to get closer to the ABS freeboard height requirements. At least that is the plan. Best Regards, David Colombo 804 College Ave Santa Rosa, CA. 95404 (707) 536-1424 www.SeaQuestor.com On Fri, May 8, 2020 at 1:24 PM Sean T.

The rubber material is the same as used on a inflatable rib. The challenge is the configuration of the tube so as to not over inflate, change the shape, and warp the exoskeleton. While not to be used as main ballast tanks, but as additional lifting capability while on the surface to lift our front pilot higher to get closer to the ABS freeboard height requirements. At least that is the plan. Best Regards, David Colombo 804 College Ave Santa Rosa, CA. 95404 (707) 536-1424 www.SeaQuestor.com On Fri, May 8, 2020 at 1:24 PM Sean T.

I believe as security so that the cable doesn't extrude through under pressure. I am wondering how they last over time being some type of plastic. However easy & cheap to change out. Also a lot would depend on the cable you are using as to how well it would seal. I am making my own. I made them for the back of my lights & tested them to 2000psi. If you look at Dougs videos on making & testing through hulls on "submarine boat" you can see that home made penetrators are a bit trickier than they look.

One is longitudinal bubble and shows very fine + - 5 ?.with less than a half degree. We use it during diving to get the boat on a propper even keel periskop depth - before we dive deeper. Otherwise we lost energy moving forward. This is in use on each dive and also to trim the boat stern heavy on the surface.. Also helpful during refueling the submarine with fuel. Another one is a weight typ from a russian submarine and in longtidudinal direction and rough + - 45 ? Only useful during crash dives in front of enemy aircrafts. (Over 45? we use the handheld Microfonspeaker on a spiral cable of the UHF radio.) One is from a sailboat +-15? and to show trim over the beam - and not very needed. Two are from the buble globe typ (flat horizontal discs with the bubble in the center and showing in all horizontal direction the trim. One of them is in the diver chamber and in use if we want to move the 750 Kg Anchor weight out and in - and very needed. The anchor weight nloks and goes heavy if the boat is not in all direction horicontal. Both have +-5? all over the horizont. On a small sub I would recommend only one : A +-5? longitudinal simple bubble typ. If you are for example 2 degree stern heavy you may will not notice it. If you drive short over the ground your stern maybe make a lot of mud clouds. vbr Carsten -----Original-Nachricht----- Betreff: [PSUBS-MAILIST] Actual Inclinometer Usage Need? Datum: 2020-05-15T14:45:29+0200 Von: "Steve McQueen via Personal_Submersibles" An: "Personal Submersibles General Discussion" So how often are small subs needing to know inclination in real life operating experiences? I have bubble inclinometers but am debating if I really need them in a 1 person K-250. I think the pilot is capable by observatory sensation to have enough awareness of inclination without an instrument. Thoughts?

On the R300, I use the inclinometers on every dive.? I have manual bubble inclinometers for both roll and pitch.? I also have a primary and backup inclinometer sensor for roll and pitch that feed into my PLC and are displayed on the HMI.? For my boat I have forward and aft MBT and a relatively short 2.2 inch span by design between my GG and CB.? So when executing a MBT flood, if the adjustable trim weight location is off then the boat could pitch forward or back.? Under certain conditions this pitch could be extreme enough to trap air in my forward or aft MBT preventing me from diving the boat.? So having the itch inclination angle measurement enables me to mitigate this.? When submerged, because of the small CG-CB spread I can drive the boat into +-45 degree pitch orientation.? Having the measurement enables me to monitor the degree of pitch.? For conventional Psubs with large CG-CB spreads, my guess is that the? measurements of pitch and roll are really not needed under normal operating conditions.? However for abnormal conditions, such as an inoperable vent valve on MBT, it is nice to have these measurements.??

I like how you have the 80cuft tanks set up. This will make refilling or changing out the tanks while the boat is still in the water relatively easy. It's pretty cool how you are morphing the external design into a sea animal. I am getting the impression that the SeaQuestor may have two purposes, one; to provide an educational inspiration for young people on STEM subjects, and two; to provide a marine scientist a seat for in situ research. Do you plan on making the exoskeleton (nose cone and dive planes in particular) bolt-on swappable for another that is less "humpback whale" and more "spaceship"?

I like how you have the 80cuft tanks set up.? This will make refilling or changing out the tanks while the boat is still in the water relatively easy.? It's pretty cool how you are morphing the external design into a sea animal. I am getting the impression that the SeaQuestor may have two purposes, one; to provide an educational inspiration for ?young people on STEM subjects, and two; to provide a marine scientist a seat for in situ research.? Do you plan on making the exoskeleton (nose cone and dive planes in particular) bolt-on swappable for another that is less "humpback whale" and more "spaceship"?? ? Tim ?

Hi guys, the progress continues on the SeaQuestor given the amount of time now available with the stay at home orders. Currently the foam work is taking shape on the exoskeleton. Lots of sanding shaping to get the lines to look and feel right. Once I'm done with one side I get duplicate the details on the opposite side. Today after sanding the front canard, I placed the periscope tube forward of the front pilot to start the final foam fill. Next I started on the aft tank area. The first 80cuft tank is set into its holder. I discovered that the lower area below the tanks will completely conceal all of the tanks, which I like. The the high pressure tanks will be connected to the three holes cut into the rear hemi. The aft rack also holds a pair of thrusters which will be vectored. The mockup shows the control? brackets yet to be mounted once I get the linear actuators. The vhf antenna bracket is also mocked up.? Everyday a little bit more is coming together.

If you put an upturned glass in a container full of water & push it down till it is just fully under the surface, the water enters the bottom of the glass to a level that is 6% of the volume of the glass. This is less than what I thought. You would only gain 6% more floatation by going from a free flooding ballast to having a flood valve. The pros of having a flood valve are the added floatation & added security that your sub won't sink if the vent valve fails.

Ultimately you are relying on your O2 sensor & even then O2 sensors have a large failure rate & a life expectancy. Rebreathers use 3-5 sensors for redundancy & compare signals. For a large sub you have a lot more time for any failure to have an effect than you would in a sub like your 1 person or Cliff's. Maybe if you insist on a Bellows Add system, have an extra O2 sensor. The second stage regulator works the opposite way than what you want with the water pressure pushing on a thin diaphragm that has a lever the other side that opens the valve. Maybe if you glued the lever to the inside of the diaphragm you could open a valve with it. You would only use the regulator valve though, as the rest would be useless. Better still, make a small sealed enclosure with a diaphragm on one face & attach the second stage lever mechanism to the outside against the diaphragm. That way you could make a screw in / out fine tuning adjuster as per DW.

Am having a click style paediatric flow regulator set at a flow level below my requirements but at a level I could survive on ( as per DW) but topping up with a rebreather solenoid valve that opens based on readings from Three O2 sensors. A piece of electronics reads the O2 level from the three O2 sensors & takes the average of the two with the nearest readings to each other as true. This system will pick up when one O2 sensor is faulty. When I saw the Triton 3000 years ago, the pilot told me they just adjusted the O2 flow from a needle valve. I could have this wrong but I did ask specifically about it. Mind you they have a big cabin & would have lots of time to make changes.

I bought these two car window motors that have been adapted for robotics, thinking I could use them on a manipulator arm joint. I went off the idea as they would need a waterproof casing & seal on the output shaft as well as oil hoses running to them from a compensator ( if you wanted to do it well). Also they are a bit weak for using in the first couple of joints. I am now liking the idea of a water hydraulic cylinder on the first 2 joints & using the blue robotics waterproof motor for the last joint, wrist & jaws. Ian Juby who is new to Psubs is an expert in robotics. Listen to him if he chimes in. Also the motors would need a motor controller that limited the amp draw or you could burn them out if they stalled.

Stevenson via Personal_Submersibles wrote: Does anyone on the list have any experience with weld fabrication of foil appendages (e.g. NACA 00xx)? Specifically, I am looking at forming a 10 gauge steel skin around a framework of 0.250" rib frames (joined on beam / pipe spine). The ribs will be CNC cut from plate, but I am unfamiliar with the forming and welding steps. I know that ship rudders and the like typically employ slot welds of some sort to join skin to ribs, but I don?t know how this is actually done in practice. Any relevant knowledge would be appreciated.

After googling & asking advice I bought a number of glues that were supposed to be good for glueing PVC. I did a number of glueing experiments & found I could peel the glue off the PVC with all products. I went to Lancer inflatables & asked them what they used on their PVC boats & they sold me unmarked cans of a two pot heat activated PVC adhesive. I think he said it was a 3M product. It was fantastic, the PVC would tear rather than the glue peeling off. Most wire jackets are PVC. I use PVC outside the hull & Teflon coated wire Which is more fire resistant inside. I looked at some professional rubber through hull fittings I had & saw that they had a thin layer of rubber vulcanised to about an inch up the jacket from where the head of the fitting was. I am copying this by coating the through hull & the jacket of the wire with the PVC glue. Doug Jackson did a series of videos on home made through hull fittings where he had failure after failure & this lead me to look in to it a bit more deeply. The water under pressure can squeeze between the insulation & wire, & the epoxy it is imbedded in, but with a layer of PVC glue over everything it can't. I had success first test at 2000psi. This looks a good product. https://www.nrs.com/repair/stabond.asp Any product they use on PVC inflatables should be good as it is water resistant as well as developed for PVC.
