Ron Leonard was the gentleman I dealt with when I bought that raw fiberglass hull. To be honest, I'm glad to hear it wasn't just me getting nowhere with IVC... I was concerned that maybe I offended them or something. Their unwillingness to furnish so much as a manual to a proven owner is confounding to me... why won't they support their machines after they leave the factory? In any case, I agree wholeheartedly that even though a semi-dry sub isn't quite a 1-atm vessel, it definitely has its merits. The ability to enter / exit the SportSub mid-dive is excellent for shallow water research, recovery, etc. I've wanted one for quite a while, but man, what a pricetag! Unlike most PSUBS, the SportSub is a concept that has improved over many design iterations. I'm glad that the business seems to be carrying on, even if it's no longer under the IVC brand name. Yes, please keep me posted if you get anywhere with them. I hope they're able to continue bringing new SportSubs to market. ~ Douglas S. -------------- next part -------------- An HTML attachment was scrubbed...

The current price for a SportSub 3 is $150,000usd! I have no idea from where the YouTube guy gets his $200,000 price tag. A few years ago I was talking with someone who was involved in purchasing one or more for various resorts and he said that IVC never got that kind of money for the subs. Apparently a buyer could negotiate the final price of a completed sub since they were basically built on request. Used SportSubs do come up for sale from time to time, but not very often and usually they are very far away.

Section 15 of Stachiw's Handbook of Acrylic is dedicated to stress relieving processes for acrylic viewports.? Stachiw states that such stress relief is required to reduce the premature crazing and failure of acrylic surfaces.? Section 15.2.1 discusses "normalization" of the material and how it both relieves stress and changes the physical properties of it.? The amount of time required to heat, bake, and cool the acrylic material depends upon thickness, but is lengthy in all cases.? I have reached out to numerous acrylic molders in New England and found that none of them have ovens that meet the technical requirements for proper normalization or annealing as described by Stachiw.?

He was selected along with a number of other artists to put in a proposal for a sculpture for the State of California. His proposal, which surprised everyone, was for an 11ft x 5ft acrylic sculpture. He was selected. What the judges didn't know was that industry had only managed to cast acrylic 2" thick & he had managed 4". He told me if he failed he could have been sued.He bought a huge autoclave & put windows on it to observe the process. He worked out how to do it & his second attempt made a successful thick casting.His 11ft x 5ft sculpture "Apollon" brought him to the attention of the American Navy & Gerry Stachiw, who commissioned him to build a deep diving sphere.Bruce said the cost of every sphere failure was about the price of a new VW car & that he would go home and tell his wife he just pushed another VW off a cliff.Shortly after my visit to him he was having an exhibition of 3d printed sculptures, so was keeping up with technology and probably using cad to design his larger metal sculptures.I am sure he would tell his story to Psubs if we had a conference in the vicinity, however I am not sure how active he would be now. I am also not sure if he would give away much on his secret formula.He gave me a large book which he signed that covered his sculpture, & had a section on acrylic & his work with the navy. Very kind of him.Alan Sent from Yahoo Mail on Android On Fri, 2 Sep 2022 at 10:52 pm, Jon Wallace via Personal_Submersibles wrote: _______________________________________________ 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...

I agree a regular stove is a possibility in most cases although a finer temperature controller would be necessary through use of a PID.? However in my case the viewport size is 24 inch which is too large for a regular house oven so I'm going to have to build a small convection oven.? Luckily we are talking relatively low temps so it doesn't have to be designed to forge-like specifications.

This is 100% Plexiglas G sheet cast to equal or better than PVHO material specifications. It is my understanding that Polycast is the only USA based manufacturer of Plexiglas G acrylic.? Their primary client is the US military and it looks like PSUBS is in play to become their close second.? While I jest, the truth is that Polymershapes told me that if it were not for US military contracts there would likely NOT be a domestic (USA) supplier of Plexiglas G.? While I am not saying Polycast is the ONLY valid manufacturer of Plexiglas G material, I guess I AM saying that if you purchase your acrylic from a discount supplier you may not be able to depend upon the accuracy of their specifications.? So I just want to share that we have an ally in both Polycast and Polymershapes for raw viewport material in the form of cast Plexiglas G acrylic.?? Polycast has distributors across the world so you can potentially purchase from a distributor closer to you than NH, however keep in mind that Polymershapes in NH has offered to answer any questions you may have...and you don't have to be afraid to tell them it's for a submarine.? They have?taken an interest in my own project and by extension our group, and seem eager to help us get the right material for our application. As some of you are aware, I am concerned that availability of quality acrylic material at a relatively reasonable price point is a potential weak point for our hobby, as well as the expertise in taking that raw material and fabricating it into a viewport worthy of a PVHO "thumbs-up" award.? I'm hoping this is an area that we can all collaborate on and develop best practices for to ensure a continued safe hobby.
