Please sign up at?http://www.psubs.org/events/PX2022?if you would like to attend.? We currently have six submarines confirmed for either public display and/or diving.? Our primary dive location is the Keuka wreck in Lake Charlevoix.? We are also expecting to have a 250 foor deep dive as well as a night dive, locations to be determined onsite.? And of course, there will be ample opportunity for comradery with your fellow psubbers. Please read carefully:1) There is no registration fee for this event however depending upon your level or participation, sharing expenses may be required. 2) Our home base will be Hampton Inn, Petoskey MI.? We do not have a group rate for this event so just make your own lodging reservations at the best rate you can get.? If you can't get a room at Hampton Inn, try Apple Tree Inn or Days Inn which are just across the street.? Additional hotels within a half mile or so are also available. 3) A schedule of events has been published at the same web location as registration.? NOTE: we have intentionally left the bulk of our schedule open for onsite changes based upon weather and water conditions so expect to see numerous TBD listed.? If you attend this event it will be important to keep in touch with event coordinators for our must updated plans as we make them. 4) We can still use help with surface support.? If you would like to help in that regard please contact me at jon.wallace at yahoo.com Looking forward to seeing you all at the expedition.

I asked for advice from some members in the past and now I have a new problem. The company that makes my dome cannot blow the dome to the specs (12 in height 24 in wide). So the max height that is acceptable is 9in to avoid the dome breaking when it is formed. So my question is ,is it acceptable to have a smaller height and I was wondering if the pressure rating of the dome will be ok.

Stevenson via Personal_Submersibles) Date: Mon, 18 Apr 2022 14:36:00 +0000 Subject: [PSUBS-MAILIST] K-250 dome advice In-Reply-To: References: Message-ID: Pressure rating of the dome will be determined by the largest effective radius of curvature of the head. In a 2:1 semi-elliptical head, that radius occurs at the apex and the pressure rating is exactly half that of a hemispherical head at the same diameter. With a blown head, it is actually forming a spherical sector bounded at the dome diameter. You can work out where the center of curvature of that sector is based on geometry, but the pressure rating will be considerably less that that of a hemispherical dome. You must also account for thinning of the dome at the apex, as it is the minimum wall thickness which will apply to the pressure calc.

If no other supplier can be found, I would suggest an acrylic cylinder on the hatch land, with a steel hatch on top of that. Or even a steel CT extension with flat viewports in it. Precision is where Greg Cottrell used to work, and he had no trouble making full sized domes. I hope the fact they can no longer make them doesn't indicate that the loss of Greg's expertise brings potential quality issues we (indeed they) don't know about.

So although you will lose in height & it will be out of round, making it's depth rating less; it will be thicker at the apex. The depth rating is calculated by the thickness at the apex.?Pressing is a better process if you can find someone that does that!Cheers Alan Sent from Yahoo Mail on Android On Tue, 19 Apr 2022 at 1:58 am, Philippe Robert via Personal_Submersibles wrote: Hi All, I have an issue in the making of my k-250 dome.

It went into the water a number of times but he still needed to make adjustments to the trim before he could dive it.? It was recently determined that the 5 feet diameter sphere was out of round (something Brian never knew about).?

Teri (Brian's widow) is looking to get $2,000 for it.? That's a bargain considering what you would get!!? First of all, there's the 3 axil? trailer (with 6 good tires) which is probably worth $2,000 by itself.??Ten SCUBA tanks that are plumbed to a high pressure manifold and high pressure valves.About 600 pounds of lead ingots (retail, lead goes for $3.33 a pound around where I live in Orange County, CA)A CO2 scrubber with absorbent insideA CO2 meterAn O2 tank with a regulatorA bailout bottle with a regulator / pressure gauge9 AGM batteries (they are Fullriver DC115-12 and sell for about $400 each).?

The thing has something like 12 portholes.? It should be noted that if you were to cut off the conning tower to use it on another boat, this alone would probably save you well over 100 hours of shop work when you consider the milling that went into making the hatch and the lathe work that went into all the portholes (to say nothing of all the welding the conning tower involved).? How much is your time worth?There's also a marine radioEmergency signaling lightElectronics associated with running the motors (motor controllers, fuses, etc.).?

I have not seen a lot of interest in the vessel as a single entity, so parting it out seems to be a practical way of saving Brian's work.? We would need someone on the West coast, or close to it, that would be willing to strip the vessel parts for resale.? That way Teri could put items on Ebay or Craigs List that the PSUBS group didn't claim.? If the SCUBA tanks are current with their hydro then she should have no problem selling those locally with a little advertising. One thing I think would help with parts resale is a thorough inventory including close up photo, model and part number when available.? We could then post those on the PSUBS facebook page. Or, maybe after the Michigan trip a bunch of us get together in California and strip the vessel ourselves.? Make a mini-convention out of it. Jim, what's the current cost of storage?

I don't know what the hydro date is on the tanks (though I'm sure they have at least some air in them).? Unless someone steps up soon and says they are interested in the whole boat I will make another trip to Ventura and check each tank's date.? I'll also pull the batteries out.? I've read that AGM batteries loose about 3% of their charge each month (someone told me just yesterday that its more than that).? If they are unrecoverable, I'll look into their disposal.? I'll get better / additional pictures of the parts that are good for use in other people's subs if I do go. The current cost of storage is right around $150 a month.? Teri texted me yesterday saying that the storage cost is going up to $168 effective June 1.? I've asked her repeatedly to let me pay for it on account of her giving me a bunch of sub related items (books, lead, CO2 absorbent, ect) after Brian's passing but she steadfastly refused.? I will be asking her again before next month's rent is due. If there's anyone on this list who would be willing to haul the sub to a location they may know of where there is little or no rent to be paid while the boat is stripped, I would be willing to pay for two or three tanks of gas to help with the costs involved with the move.

I have not seen a lot of interest in the vessel as a single entity, so parting it out seems to be a practical way of saving Brian's work.? We would need someone on the West coast, or close to it, that would be willing to strip the vessel parts for resale.? That way Teri could put items on Ebay or Craigs List that the PSUBS group didn't claim.? If the SCUBA tanks are current with their hydro then she should have no problem selling those locally with a little advertising. One thing I think would help with parts resale is a thorough inventory including close up photo, model and part number when available.? We could then post those on the PSUBS facebook page. Or, maybe after the Michigan trip a bunch of us get together in California and strip the vessel ourselves.? Make a mini-convention out of it. Jim, what's the current cost of storage?

The thing has something like 12 portholes.? It should be noted that if you were to cut off the conning tower to use it on another boat, this alone would probably save you well over 100 hours of shop work when you consider the milling that went into making the hatch and the lathe work that went into all the portholes (to say nothing of all the welding the conning tower involved).? How much is your time worth?There's also a marine radioEmergency signaling lightElectronics associated with running the motors (motor controllers, fuses, etc.).? This alone was probably not cheap.Cabin pressure gauge that's made for a small submarine!Large depth gaugeIt's actually registered as a boat in California! All total, it's probably got over $10,000 worth of parts.? ? Here's a link to 7 Youtube videos you might want to see (showing the evolution of the sub and it's sea trials) if you've not seen them yet:??https://www.youtube.com/channel/UCz_JObSMe33gn6l_szab4AA? When watching the videos you might notice that the boat got about 6 feet shorter in the end as Brian cut off 6 feet of the front to help with the trim.? Attached are also a few pictures.
