I've moved all the videos to a new proper youtube channel. Not 100% sure ive set it up correctly, but I think its mostly ok. Need to tinker with it and put on some more info. I will put some more videos on in due course. Diving again next weekend (different place), plus some footage of modifications I am making, plus the (rather slow) progress of the new sub. Got some other interesting things not sub related as well. I will remove the videos off the old channel which was Anitas account as I didnt have my own then. I had over 80 subscribers, so i thought i better do it properly. If anyone is a current subscriber, maybe you could re-subscribe to the new one.... :) This video is pretty rubbish as I was filming on my phone and waving it around all over the place. I am going to get a better camera for next time and mount it still. I did go over the scallop beds again, but yet again, failed to film anything. Also came across a huge tangle of rope on the seabed at about 10 meters. I think it was a mooring buoy that had tangled up. It looked extremely hazardous and with the large bobber floating mid water, I couldnt help thinking it looked like a chain mine. I am aware of my rear prop being exposed, and I have actually made a guard for it, but I havent got time to fit it this season. So anyway, i kept out of the way, but again the camera was pointing in the wrong place. https://youtu.be/A3Ve3yrLX4M Kind Regards James -------------- next part -------------- An HTML attachment was scrubbed...

This acts to pull the buoy to be vertically in line with the anchor, while still allowing for tidal height change and sea state. With a deployed buoy, you could do something similar at the buoy end, so that once the buoy reached surface any additional deployed line would be pulled down by a counterweight and keep the buoy in position. You can also shackle the counterweight back to the main line, so that it follows it down, and you have the entire length of that line as the compensation range, and only need to reel in line when the counterweight hits the sub, which you could verify visually if the land point was covered by a viewport.

Even a ballast tank system that allows the vessel to submerge less than 10-20 meters below surface level would suffice for research purposes. It is mainly to test the effectiveness of various radar absorbing materials, so there is no need for the vessel to be able to reach great depths in this case, although if it's possible to engineer such modifications that would be fantastic. If you do view them in person, please do inform me as to what they're equipped with. Either way, I would love to come see them myself in person too whenever that is possible.

The plaster of Paris will have to be pretty dry & any resin from your fibreglassing would suck in to it unless you gave it several coats of shellac first then put on a mould release wax. This is from memory from a long time ago. Also I have vague memories of coating polystyrene with pva glue which doesn't dissolve the polystyrene, & fibreglassing on to that. Will take a big block of polystyrene.

You've been watching too many of Hank's videos lol. Is it a symmetrical shape that can be turned in any way? If you are filling it with syntactic foam you could shape that & fibreglass over the top. Karl Stanley has used car bodies as molds, perhaps you could find something pre made you could mold over. I have used big blocks of polystyrene like David is doing. I also used a large exercise ball to make a sphere. I think the way you are proposing will be difficult. You would need a lot of plaster as you would need it thick to be able to sand or work it without breaking it. Might not be as cheap as you think. It would be really difficult to get a good finish. One of those jobs where you get half way through and say "Why the hell did I start this".

Partly because of the size of area you need to work really, really fast just as it's setting up. How big does the cone need to be? And can it be spherical or does it have to be cone shaped? If I may suggest, a good old dollar store beachball or sports ball makes an excellent mold. You can inflate it to the right size, and then plaster that and put plastered burlap on the outside of the plaster to hold its shape. Simply deflate the ball to remove it, and now you have a nice, even, smooth finish plaster mold which will be much more easy to release your fiberglass from. And your fiberglass winds up with a super nice, smooth finish. Further to that, but along the same idea, you can get tons of cheap, inflatable pool toys that may have a cone shape you can use as well if you need a cone shape. Just be aware that pressure changes will occur in the inflatable because of temperature variations. Namely, plaster will both heat up the ball and the air in the ball, and so the ball will expand. This was a fatal problem for me because I was trying to make a huge globe, so I either had to make it in two halves (and the halves would invariably wind up different sizes because of the variable expansion of the ball as a mold) or make one sealed sphere, which both trapped in the heat and the outward pressure of the air expanding inside the ball would stress the plaster mold and crack it. I had to have tolerances that were too tight so the two halves would match to make a sphere. But in your case, I suspect you have some tolerance and room for error on the size of the cone/sphere? So that shouldn't be a problem for you then. Do you have access to a wood lathe? Can you turn a stryrofoam blank and produce a mold from that? Or apply the fiberglass straight to the styrofoam? Sculpting fiberglas and getting a decent finish is a pain. You've got the right idea to make a mold in which to cast the cone - that's the best way. For what it's worth, here's one short article on sculpting a fiberglass nose cone: https://www.apogeerockets.com/education/downloads/Newsletter413.pdf But by far and away, the best thing is to start with something cone-shaped and the right size already. Oh - if you can get away with a sphere, you can blow-mold a sphere as well.

There are people that make some pretty sophisticated sand sculptures. As an artist I developed a technique for taking sand patterns off the beach. I would have a very diluted pva glue in a bottle with just a manual spray mechanism. ( the type you might find in your kitchen) I would wet the sand with a fine mist so as not to disturb the surface, give it several hours to dry, & repeat the process several times. I would then remove the pattern from the surrounding sand & back it with fibreglass ( in situ on the beach) then take it home. If you googled on sand sculpture you could make the form & then use my technique to solidify it.

Partly because of the size of area you need to work really, really fast just as it's setting up. How big does the cone need to be? And can it be spherical or does it have to be cone shaped? > If I may suggest, a good old dollar store beachball or sports ball makes an excellent mold. You can inflate it to the right size, and then plaster that and put plastered burlap on the outside of the plaster to hold its shape. Simply deflate the ball to remove it, and now you have a nice, even, smooth finish plaster mold which will be much more easy to release your fiberglass from. And your fiberglass winds up with a super nice, smooth finish. > Further to that, but along the same idea, you can get tons of cheap, inflatable pool toys that may have a cone shape you can use as well if you need a cone shape. > Just be aware that pressure changes will occur in the inflatable because of temperature variations. Namely, plaster will both heat up the ball and the air in the ball, and so the ball will expand. This was a fatal problem for me because I was trying to make a huge globe, so I either had to make it in two halves (and the halves would invariably wind up different sizes because of the variable expansion of the ball as a mold) or make one sealed sphere, which both trapped in the heat and the outward pressure of the air expanding inside the ball would stress the plaster mold and crack it. I had to have tolerances that were too tight so the two halves would match to make a sphere. But in your case, I suspect you have some tolerance and room for error on the size of the cone/sphere? So that shouldn't be a problem for you then. > Do you have access to a wood lathe? Can you turn a stryrofoam blank and produce a mold from that? Or apply the fiberglass straight to the styrofoam? Sculpting fiberglas and getting a decent finish is a pain. You've got the right idea to make a mold in which to cast the cone - that's the best way. > For what it's worth, here's one short article on sculpting a fiberglass nose cone: https://www.apogeerockets.com/education/downloads/Newsletter413.pdf > But by far and away, the best thing is to start with something cone-shaped and the right size already. > Oh - if you can get away with a sphere, you can blow-mold a sphere as well. > > Ian > > On Wed, Aug 12, 2020 at 12:32 AM Brian Cox via Personal_Submersibles wrote: > Alan, I could coat the plaster of paris with resin and then polish that really well , then apply mold release to that , then shoot gel coat over the mold release , then fiberglass and resin over the gel coat.

In the ABS Rules, the specified minimum distance between CB and CG is 2", which isn't much. While you can assume a fixed position for CG in the light ship condition, a vessel with any combination of stores, fuel, loose equipment and crew aboard will be subject to movement of CG with respect to the vessel as the vessel rolls - particularly as crew weight can be significant with respect to overall vessel weight in small submersibles. As such, it is possible to approximate zero stability (analogous to a cylinder floating on the surface, which has no tendency to right to a preferred orientation) in a submerged vessel merely by allowing crew and stores to move about, unless care is taken in design to entirely preclude the possibility of the CB-CG righting moment to be zero or less. Transitional stability reduction occurs on submergence because the vessel is transitioning from a condition of form stability to one of mass centroid stability. In the form-stable condition, the vessel has positive metecentric height due to CB being displaced laterally as the vessel rolls. Even if CG is above CB (as in most surface ships), as the vessel rolls, the shape of the submerged portion of the hull changes to push CB laterally outward, which provides a righting moment against CG to restore the hull to upright. Stability in this condition is techically zero when the vessel is perfectly upright, but rapidly increases with increasing angle of roll up to the point of diminishing stability (roll limit). As a vessel submerges, a few things happen simultaneously: 1) The form stability is lost, because angle of roll no longer has any substantial impact on the lateral position of the CB, and of course once fully submerged the CB is constrained to the midline of a laterally symmetrical vessel, 2) The portion of the hull previously above the waterline begins to contribute to buoyancy, moving the CB upwards. Unless the vessel was specifically designed to maintain CG below CB at all times (i.e. even while surfaced), this means that the vertical order of CB and CG will exchange places, which implies that there is a point in time during the transition at which the vessel has precisely zero stability. 3) Any gas spaces exposed to sea which are not vented sufficiently rapidly (e.g. main ballast tanks) will exhibit volumetric compression due to hydrostatic pressure, worsening any initial list if there is differential hydrostatic pressure from side to side, because air in the deeper tank(s) will compress to a greater extent. Consequently, it is recommended in design to ensure that the transition between surfaced and submerged condition can occur as rapidly as possible, such that the vessel's momentum and inertia compensate for the momentary total loss of stability during the transition. The only condition which can preclude this requirement is if the vessel has no reliance on form stability in the surfaced condition (i.e. CG is below CB even when surfaced, regardless of crew movement etc). This is most typical of smaller vessels. The other thing to consider is damaged stability. While PSubs (typically) only have a single crew compartment, damage to an external ballast tank can represent a condition which could possibly create a roll (or pitch) moment contrary to the design righting moment in the intact condition, and it is incumbent on the designer to consider the effect of e.g. ballast tank(s) blown empty on one side of the vessel only, and to ensure that this both does not roll the vessel past any operational roll angle limit, nor prevent emergency egress from the vessel by not considering the resultant submergence of all exit hatches in the damaged condition, unless some contingency plan is in place to account for the possibility.

In the ABS Rules, the specified minimum distance between CB and CG is 2", which isn't much. While you can assume a fixed position for CG in the light ship condition, a vessel with any combination of stores, fuel, loose equipment and crew aboard will be subject to movement of CG with respect to the vessel as the vessel rolls - particularly as crew weight can be significant with respect to overall vessel weight in small submersibles. As such, it is possible to approximate zero stability (analogous to a cylinder floating on the surface, which has no tendency to right to a preferred orientation) in a submerged vessel merely by allowing crew and stores to move about, unless care is taken in design to entirely preclude the possibility of the CB-CG righting moment to be zero or less. > > Transitional stability reduction occurs on submergence because the vessel is transitioning from a condition of form stability to one of mass centroid stability. > > In the form-stable condition, the vessel has positive metecentric height due to CB being displaced laterally as the vessel rolls. Even if CG is above CB (as in most surface ships), as the vessel rolls, the shape of the submerged portion of the hull changes to push CB laterally outward, which provides a righting moment against CG to restore the hull to upright. Stability in this condition is techically zero when the vessel is perfectly upright, but rapidly increases with increasing angle of roll up to the point of diminishing stability (roll limit). > > As a vessel submerges, a few things happen simultaneously: > > 1) The form stability is lost, because angle of roll no longer has any substantial impact on the lateral position of the CB, and of course once fully submerged the CB is constrained to the midline of a laterally symmetrical vessel, > > 2) The portion of the hull previously above the waterline begins to contribute to buoyancy, moving the CB upwards. Unless the vessel was specifically designed to maintain CG below CB at all times (i.e. even while surfaced), this means that the vertical order of CB and CG will exchange places, which implies that there is a point in time during the transition at which the vessel has precisely zero stability. > > 3) Any gas spaces exposed to sea which are not vented sufficiently rapidly (e.g. main ballast tanks) will exhibit volumetric compression due to hydrostatic pressure, worsening any initial list if there is differential hydrostatic pressure from side to side, because air in the deeper tank(s) will compress to a greater extent. > > Consequently, it is recommended in design to ensure that the transition between surfaced and submerged condition can occur as rapidly as possible, such that the vessel's momentum and inertia compensate for the momentary total loss of stability during the transition. The only condition which can preclude this requirement is if the vessel has no reliance on form stability in the surfaced condition (i.e. CG is below CB even when surfaced, regardless of crew movement etc). This is most typical of smaller vessels. > > The other thing to consider is damaged stability. While PSubs (typically) only have a single crew compartment, damage to an external ballast tank can represent a condition which could possibly create a roll (or pitch) moment contrary to the design righting moment in the intact condition, and it is incumbent on the designer to consider the effect of e.g. ballast tank(s) blown empty on one side of the vessel only, and to ensure that this both does not roll the vessel past any operational roll angle limit, nor prevent emergency egress from the vessel by not considering the resultant submergence of all exit hatches in the damaged condition, unless some contingency plan is in place to account for the possibility. > > Sean > > -------- Original Message -------- > On Aug. 15, 2020, 09:58, Tim Novak via Personal_Submersibles < personal_submersibles at psubs.org> wrote: > > Looks great, Brian. > > Good photos.

Personally I don't think it will, because you have got it to its most precarious stage with just the conning tower out of the water. If it tipped to one side the conning tower would give it flotation & stop it going right over. An experienced Triton pilot told me he gets under the water as fast as he can, because that's when you are the most unstable.

For PSUBS situations though, whatever answer you get is irrelevant. Even 1 pound of additional displacement from air in the MBT will cause you to rise, just not very fast. Drag is a V^2 relationship, so in order to go twice as fast, you would need four times the buoyancy. In shallow depths, the air is also rapidly expanding, so if you're interested in time-to-surface you may have to account for that as well. In the ocean there is a thermocline somewhere around 300 or 400 feet. The density change of the water is enough to notably slow, or even stop ascent or descent. For extremely large, or extremely deep-diving vehicles, you begin noticing either increasing or decreasing total net vehicle buoyancy depending on if the hull is more or less compressible than the surrounding seawater. In the end, the most practical thing to do is to add or vent air to obtain and maintain the speed that you want. Like Vance says, watch the bubbles. That answer isn't satisfying enough if you're sitting at 300ft without enough weight to go deeper, or if you're sitting at the drawing board trying to size a VBT or an appropriate amount of weight for an ascent/descent dropweight system.

Two variables are, 1) enough remaining pressure in the air tank to exceed pressure at depth for a given volume of air, 2) enough volume of air at a specific depth to displace enough water in the MBT to initiate surfacing.?

The specific rate is not as important as just ensuring enough buoyancy to overcome things like density changes or other forces as you've identified.? What I am actually trying to do is ensure I have enough HP air at a specific depth to ensure enough displacement occurs to ensure surfacing.? This seems to be much more critical for deep diving subs than shallow diving ones. Using K350 specs as a guide, Kittredge required 128 pounds of lead for the emergency drop weight system.? I assume then, that 128 pounds of positive buoyancy is "enough" to initiate surfacing from 350 feet in a 3000 pound vessel and overcoming any external forces such as drag, thermocline, etc.? For the moment, until someone tells me differently, I think it would be reasonable to suggest that half that amount or 64 pounds displacement (1 cu ft seawater) is even enough to ensure surfacing. Jon ? On Sunday, August 16, 2020, 03:10:52 PM EDT, River Dolfi via Personal_Submersibles wrote: Jon,It's a simple question, but there is no simple answer. For PSUBS situations though, whatever answer you get is irrelevant. Even 1 pound of additional displacement from air in the MBT will cause you to rise, just not very fast. Drag is a V^2 relationship, so in order to go twice as fast, you would need four times the buoyancy. In shallow depths, the air is also rapidly expanding, so if you're interested in time-to-surface you may have to account for that as well. In the ocean there is a thermocline somewhere around 300 or 400 feet. The density change of the water is enough to notably slow, or even stop ascent or descent. For extremely?large, or extremely deep-diving vehicles, you begin noticing either increasing or decreasing total net vehicle buoyancy depending on if the hull is more or less compressible than the surrounding seawater. In the end, the most practical thing to do is to add or vent air to obtain and maintain the speed that you want. Like Vance says, watch the bubbles. That answer isn't satisfying enough if you're sitting at 300ft without enough weight to go deeper, or if you're sitting at the drawing board trying to size a VBT or an appropriate amount of weight for an ascent/descent dropweight system.

There are DNV-GL rules referring to how much reserve air you should have. I think it was enough to blow your tanks 4 X, but a while since I read it. Could look it up if you like.

The specific rate is not as important as just ensuring enough buoyancy to overcome things like density changes or other forces as you've identified. What I am actually trying to do is ensure I have enough HP air at a specific depth to ensure enough displacement occurs to ensure surfacing. This seems to be much more critical for deep diving subs than shallow diving ones. > > Using K350 specs as a guide, Kittredge required 128 pounds of lead for the emergency drop weight system. I assume then, that 128 pounds of positive buoyancy is "enough" to initiate surfacing from 350 feet in a 3000 pound vessel and overcoming any external forces such as drag, thermocline, etc. For the moment, until someone tells me differently, I think it would be reasonable to suggest that half that amount or 64 pounds displacement (1 cu ft seawater) is even enough to ensure surfacing. > > Jon > > > > On Sunday, August 16, 2020, 03:10:52 PM EDT, River Dolfi via Personal_Submersibles wrote: > > > Jon, > It's a simple question, but there is no simple answer.

Drag is a V^2 relationship, so in order to go twice as fast, you would need four times the buoyancy. In shallow depths, the air is also rapidly expanding, so if you're interested in time-to-surface you may have to account for that as well. > > In the ocean there is a thermocline somewhere around 300 or 400 feet.

Like Vance says, watch the bubbles. That answer isn't satisfying enough if you're sitting at 300ft without enough weight to go deeper, or if you're sitting at the drawing board trying to size a VBT or an appropriate amount of weight for an ascent/descent dropweight system. > > Thanks, > > -River J.

You would have to know the drag coefficient and a reference area of the sub in question in the up and down direction. Usually that kind of number is determined with fancy CFD or wind tunnel testing.

I'm sure I'm looking beyond a practical application but I'm imagining entering my target dive depth at the surface and then having the software predict if there is enough HP air volume to blow the tanks at that depth to initiate surfacing. Two variables are, 1) enough remaining pressure in the air tank to exceed pressure at depth for a given volume of air, 2) enough volume of air at a specific depth to displace enough water in the MBT to initiate surfacing. I'm guessing it's not all that much, but I'm not sure what "enough" is and trying to quantify that.

In which case there should be enough air to moveyou off the bottom. Of course with expanding air your speed will increase asyou rise.There are DNV-GL rules referring to how much reserve air you should have.I think it was enough to blow your tanks 4 X, but a while since I read it. Couldlook it up if you like. ABS must have something similar.Alan On 17/08/2020, at 8:11 AM, Jon Wallace via Personal_Submersibles wrote: River, Exactly, which is why I was looking for a "reasonable" vertical rate but it may have been misleading to mention that.? The specific rate is not as important as just ensuring enough buoyancy to overcome things like density changes or other forces as you've identified.? What I am actually trying to do is ensure I have enough HP air at a specific depth to ensure enough displacement occurs to ensure surfacing.? This seems to be much more critical for deep diving subs than shallow diving ones. Using K350 specs as a guide, Kittredge required 128 pounds of lead for the emergency drop weight system.? I assume then, that 128 pounds of positive buoyancy is "enough" to initiate surfacing from 350 feet in a 3000 pound vessel and overcoming any external forces such as drag, thermocline, etc.? For the moment, until someone tells me differently, I think it would be reasonable to suggest that half that amount or 64 pounds displacement (1 cu ft seawater) is even enough to ensure surfacing. Jon ? On Sunday, August 16, 2020, 03:10:52 PM EDT, River Dolfi via Personal_Submersibles wrote: Jon,It's a simple question, but there is no simple answer. For PSUBS situations though, whatever answer you get is irrelevant. Even 1 pound of additional displacement from air in the MBT will cause you to rise, just not very fast. Drag is a V^2 relationship, so in order to go twice as fast, you would need four times the buoyancy. In shallow depths, the air is also rapidly expanding, so if you're interested in time-to-surface you may have to account for that as well. In the ocean there is a thermocline somewhere around 300 or 400 feet. The density change of the water is enough to notably slow, or even stop ascent or descent. For extremely?large, or extremely deep-diving vehicles, you begin noticing either increasing or decreasing total net vehicle buoyancy depending on if the hull is more or less compressible than the surrounding seawater. In the end, the most practical thing to do is to add or vent air to obtain and maintain the speed that you want. Like Vance says, watch the bubbles. That answer isn't satisfying enough if you're sitting at 300ft without enough weight to go deeper, or if you're sitting at the drawing board trying to size a VBT or an appropriate amount of weight for an ascent/descent dropweight system.

The longitudinal transfer is surely just the additional displacement provided by the CT when you submerge, since in relative terms it?s larger and further aft than on a typical psub. Perhaps just let it do a bit of a wheelie on the surface so it?s trimmed out when underwater? Or is it so inclined on the surface that the hatch opening gets close to the waterline? Then yes... I see a big movable weight coming. Im looking forward to some UW or onboard footage next!

Congrats! When the bow went down like that, did it rest on the bottom? That was a pretty radical angle, and the speed of it makes me think you had a massive free surface displacement in the MBT. Normally that induces lateral instability, but due to the length of your boat in this case it would be longitudinal instability. > > Thanks, > Alec > > On Wed, Aug 26, 2020 at 10:44 AM Brian Cox via Personal_Submersibles wrote: > Hi All, > Have a couple of videos from down at the harbor: > > > https://www.youtube.com/watch?v=iERfLiioGJA&t=628s > > > > https://www.youtube.com/watch?v=OGiAqeocq4s > > > Cheers, > > Brian > > > _______________________________________________ > Personal_Submersibles mailing list > Personal_Submersibles at psubs.org > http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ > Personal_Submersibles mailing list > Personal_Submersibles at psubs.org > http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ > Personal_Submersibles mailing list > Personal_Submersibles at psubs.org > http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ > Personal_Submersibles mailing list > Personal_Submersibles at psubs.org > http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ > Personal_Submersibles mailing list > Personal_Submersibles at psubs.org > http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles > _______________________________________________ > Personal_Submersibles mailing list > Personal_Submersibles at psubs.org > http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles -------------- next part -------------- An HTML attachment was scrubbed...

Couple of points.? It is nice how with your long sub trailer that enable you to tow the psub and the tinder, you can launch and recover the boat without having to install a trailer extender.? What is the distance from the mid plane of the axles to the trailer coupler?? In the video, you edited out the part where you entered the boat.? Can you describe the process? Do you enter the boat from the tender or did you beach the boat near the ramp and climb in?? Like Sean, I am interested in your observations on looking through this cylindrical viewport.? With gamma you had experience with flat and curved view viewports so I am interested in how it affects what you are viewing compared with Gamma. How does it distort the shape of object when you dive? Thanks for sharing the video.
