In-Reply-To: References: Message-ID: Hi Brian, I remember you being delighted by Jocassee lake after visiting with Harold. It looks incredibly similar to Summersville Lake in WV, which was my favorite until I took Snoopy to Seneca. They're both created by a damn, both have limestone cliffs, reportedly similar visibility, etc. The scenery and shore look exactly the same (both wonderful). Jocassee has the advantage of local support, which we don't have at Summersville but do at Seneca. Personally I'd vote for Seneca again, because it does have one thing that Summersville doesn't, and that's that the visibility remains good even right after massive rain. At Summersville the visibility is good, but only if the weather has been dry. Perhaps man made lakes get a lot more runoff than ones that have been around since the last ice age. I wonder whether Jocassee might be similarly fragile. Any idea?

I am thinking of making the removable ends slightly different to how I did it on the K. On that, I put the flanges on to make like a standard flanged end. However, I made them like you would a hatch, ie with the centre of the flange being welded to the centre of the tube. So there is overlap on both sides of the ID and OD of the tube. Bit difficult to explain. Pic here of the K ones when I was making them. K350 pod ends. The problem with these is that the overlap onto the inside diameter of the tube makes the hole smaller and you cant slide the trays out. With the new one, I have made rolling trays and I want them to slide straight out. So, I am thinking I can make the flanges flush with the inside diameter of the tube. I have not started this part yet, so any advice greatly appreciated. ? Not a very good picture, but new trays with rollers made.

For steel plate from the mill, that difference is significant. I do not know how much weaker the hot rolled rings would be than cold, or if it matters. I'm pretty sure the ABS design calculations don't take this additional strength into account. It's my understanding that in experimental tests those formulae tend to give rather conservative estimates of collapse depth, which is on purpose. Sean might be able to tell you in more detail. -River J. Dolfi -------------- next part -------------- An HTML attachment was scrubbed...

In-Reply-To: <122879127.4487038.1528838856275@mail.yahoo.com> References: <20180612140553.D2565A60@m0117566.ppops.net> <122879127.4487038.1528838856275@mail.yahoo.com> Message-ID: The reason is that per stress calculations what really counts is the moment of inertia around the intersection of stiffener and shell. That means the material further from that intersection contributes much more than the material closer to it. To visualize this intuitively, imagine a stiffener made by bending a flat bar the "easy way" versus a stiffener that is cut out of a flat ring and is therefore much deeper. Both rings might weigh the same, but the one that's bent the easy way and has its center of mass close to the shell does a whole lot less stiffening than the deep ring of the same weight. Now taking the same logic further, the most efficient configuration is a substantial flange that is held well off the shell by a deep web, even if the web is not very thick.

It would be interesting to know what amps the motor is drawing at full speed as you may be able to use a larger propeller! Perhaps check that stray voltage with the motors off & on to isolate it!

At this point I have no way of measuring the amp draw, I need to get myself an amp meter. As this was a harbor patrol test I hadn't really considered an extensive run through. Actually I think I have some sort of short some where. While I was testing with a volt meter I discovered I was getting some voltage to the hull , the only thing I can thing that it's coming from is one of my electrical thru hulls. Maybe it's possible that there is a slight contact where I had to bend the epoxy electrodes a little bit , because everything else is isolated. I'm going to have to isolate those electrodes and do continuity tests to see if that is the case . I don't think it could be the motors because they are totally isolated by a delron disc where the motors turn. It didn't seem to effect the running of the motors but I need to run it down. > > Brian > > > > > --- personal_submersibles at psubs.org wrote: > > From: hank pronk via Personal_Submersibles > To: Hugh Fulton via Personal_Submersibles > Subject: Re: [PSUBS-MAILIST] Still pics > Date: Sat, 16 Jun 2018 00:55:13 +0000 (UTC) > > Brian, > How did the golf cart motors work, any trouble, amps draw? you have two? if I recall. > Hank > > > On Friday, June 15, 2018, 5:37:19 PM MDT, Hugh Fulton via Personal_Submersibles wrote: > > > Well done Brian. > > Guess that is the opening chapter of the book you will write one day. > > A little bit of honey goes a long way.

Most of what they don't specify as a limitation, they refer to adequate outside codes (ASME boiler codes, etc.). Recall the original design from Captain Kittredge for a pod closure. Nothing more than a roll of SS the same thickness as the pod welded inside so the hatch and O-ring slide over to mate with the machined but otherwise non strengthened end of the pod tube itself. Works like a champ. And was certified by Lloyd's and the Japanese certifying agency both at one time or another. I didn't see a pod open on the K-600, so I don't know if he strengthened it further or not. Probably not. The pods are calculated for like 4000 feet or something. They're the toughest thing on the boat.

Whatever your end flange is, it should meet the moment of inertia requirements for a heavy stiffener under the ABS Rules. This takes care of hoop stress and tripping concerns, and then you need only design for the shear and bending loads. Hatch land geometry is up to you, but the material surrounding the hole (if not a complete head in of itself) needs to be reinforced, and as per the discussion in the ABS Rules, the reinforcement must be integral / CJP joined to the hull shell and not welded as a doubler plate / shell. Additional details can be found in Section 8 of the ASME Boiler and Pressure Vessel Code, and in the ABS Steel Vessel Rules, which is also a free download. Your flanges / hatch lands should be sufficiently strong in both shear and bending, but you'll have to do the calculations for your design. Conical hatches can mirror the geometries of conical viewport rings per PVHO-1 and Jerry Stachiw's book.

This was the first expedition planned with the framework of https://www.innerspacescience.org to align the use of personal subs with science objectives. That allowed us to partner with three organizations - UC Davis's Tahoe Environmental Research Center, the California Tahoe Conservancy, and the Tahoe Regional Planning Agency. They facilitated everything from our boat inspections to finding a base of operations on land, but above all provided institutional-grade surface support vessels as well as scientists. One of the first objectives was to depth test R300, and she passed with flying colors (no surprise!) Cliff had a cool way of doing the test. Since everything on R300 is controlled by a PLC, he programmed an entire automated dive cycle beginning with a 45 minute delay. He attached ballast to replace the pilot, clicked a button to start the clock, and closed the hatch. The timer gave us time to tow the boat out to depth, then automatically flooded ballast.. Attached to a line, R300 descended to around 400 feet, stayed there half an hour, fired vertical thrusters to rise, and a few feet from the surface blew ballast. Another objective was to shoot some sub-to-sub video. That day the visibility wasn't optimal, but we did get it. It was the first time I'd done a multi-sub dive and it was as much fun as you'd expect. Video to follow... The scientists had a bunch of objectives. In general we did not have the bottom time to carry out the methodical counts they were attempting, but we were able to get their eyeballs on the spots they were wanting to make the counts at, and get video. Some hypothesis were met, but new questions arose too. One of the spots they wanted to study was the top of an UW mount. Hank was able to find it, climb up, and circle the top. That was an accomplishment, because the top was only about 20m across and we were unable to locate the mount with depth sounders from the surface even when provided GPS coordinates. These spots were in 200? plus, so had not been visited on SCUBA. We were able to offer Gamma rides to a few VIPs but more importantly to many young students. You should have seen the reactions. Another time, Cliff beached R300 on a popular sandy beach and found himself giving an impromptu lecture to a circle of young people. The most exciting incident came on the last day when Cliff gave Jon and Dave some training followed by solo dives. On Dave?s dive one of the side thrusters sucked in a rope and he found himself tethered to the bottom in 77 feet. Minutes later the surface support boat?s outboard accidentally cut off the comms transducer. However, Dave followed R300?s emergency plan to the letter and blew MBTs, which ripped him free. Unfortunately we don?t have video of that incident, but it would have reflected well on all involved. The sub had a pinger to locate it, had a plan, and the plan was followed. Now we need suggestions for the next expedition! Best, Alec -------------- next part -------------- An HTML attachment was scrubbed...

They facilitated everything from our boat inspections to finding a base of operations on land, but above all provided institutional-grade surface support vessels as well as scientists. > > One of the first objectives was to depth test R300, and she passed with flying colors (no surprise!) Cliff had a cool way of doing the test. Since everything on R300 is controlled by a PLC, he programmed an entire automated dive cycle beginning with a 45 minute delay. He attached ballast to replace the pilot, clicked a button to start the clock, and closed the hatch. The timer gave us time to tow the boat out to depth, then automatically flooded ballast.. Attached to a line, R300 descended to around 400 feet, stayed there half an hour, fired vertical thrusters to rise, and a few feet from the surface blew ballast. > > Another objective was to shoot some sub-to-sub video. That day the visibility wasn't optimal, but we did get it. It was the first time I'd done a multi-sub dive and it was as much fun as you'd expect. Video to follow... > > The scientists had a bunch of objectives. In general we did not have the bottom time to carry out the methodical counts they were attempting, but we were able to get their eyeballs on the spots they were wanting to make the counts at, and get video. Some hypothesis were met, but new questions arose too. One of the spots they wanted to study was the top of an UW mount. Hank was able to find it, climb up, and circle the top. That was an accomplishment, because the top was only about 20m across and we were unable to locate the mount with depth sounders from the surface even when provided GPS coordinates. These spots were in 200? plus, so had not been visited on SCUBA. > > We were able to offer Gamma rides to a few VIPs but more importantly to many young students. You should have seen the reactions. Another time, Cliff beached R300 on a popular sandy beach and found himself giving an impromptu lecture to a circle of young people. > > The most exciting incident came on the last day when Cliff gave Jon and Dave some training followed by solo dives. On Dave?s dive one of the side thrusters sucked in a rope and he found himself tethered to the bottom in 77 feet. Minutes later the surface support boat?s outboard accidentally cut off the comms transducer. However, Dave followed R300?s emergency plan to the letter and blew MBTs, which ripped him free. Unfortunately we don?t have video of that incident, but it would have reflected well on all involved. The sub had a pinger to locate it, had a plan, and the plan was followed. > > Now we need suggestions for the next expedition! > > > Best, > Alec
