The second is to provide depth readings indicating when the vessel is approaching the bottom which is useful when visibility is poor.

The intent is to determine maximum depth survival of an off-the-shelf unit since there is no such data available from the manufacturer. If the unit fails during testing a post-test analysis will be performed to determine where the failure occurred, and how it might be corrected.?

Turns out that they make this foam in a standard block size. Any size less than the block size is sold at the full price and the drops are thrown away unless you ask for them. This was an important piece of information that they neglected to tell me until after the product was shipped and I realized that my shipped price was substantially more per cf than quoted. Their excuse was that I did not tell them I wanted the drops.

But let?s not get excited, only half of the oxygen consumed and exhaled as co2 would be recycled, one would still need oxygen make up for the other half. CO is lethal at 0.05% concentration and we d need to get rid of it. Plus it is flamable. Now, it is more reactive than Co2 so perhaps easier to get rid of. And the thing consumes quite a lot of power to heat it up to 800degC and maintain input voltage. So that s extra batteries. Good luck with vaccine recovery!

I reached out to Brian Hughes, as he is part of the latter, and he liked the idea. Then I reached out to our main contact at the university. He was fine with it as well, and thinks we may be able to borrow a classroom for presentations. However, it is a little early for him to set dates because they are in the middle of a Covid wave at present and have not been able to announce any policies for the fall yet. Basically, they are closed. I'm very hopeful we will see things get better as vaccinations continue, but we will need to check back with the university probably in a couple of months.

Paint the hatch. Make sure it's sufficiently protected. Pay special attention when painting the groove itself. You don't want too much build up, especially in the inner corners. Once the paint has cured, put on a sweatband and apply elbow grease to the o-ring groove using ?fine grit sandpaper. Do it by hand. What you want to do is work/sand/polish the paint down to pretty much its minimal thickness without breaking through to the undercoat (or not much, anyway). If you think the sanding has thinned your paint coating too much, then wipe the groove down with solvent, thin a little more paint in a paper cup, and add a layer back to the groove with an artist's brush. Let it hard cure again. Then get the sandpaper back out. You are looking to have a very smooth surface in there. You'll get a matte finish, rather than shiny, which will help hold the grease if nothing else. You can't depend on the original application for smoothness. Once she's slick to the touch, clean carefully, and apply a little of your favorite o-ring grease. Then grease the o-ring and install. You're done. It doesn't hurt to pull the o-ring if the sub will be laid up between operations. Wipe with a very clean cloth. Re-grease groove and o-ring using your bare hands so you can feel any grit that might have been picked up. The sanding really isn't that big a job on the bench, but it needs to be done, and carefully. Once you get to that point, all you have to do is keep an eye on things, close the hatch, and go diving. All the Perry boats had painted o-ring grooves and Monel mating surfaces, and all of them got the extra elbow grease to polish those grooves to a fair-the-well. Never had one leak. Ever. And because we were fussy about the maintenance, I never saw a speck of rust in there, even after a hard season. Pretty good results for half an hour's work on the bench.Vance -----Original Message----- From: hank pronk via Personal_Submersibles To: Jon Wallace via Personal_Submersibles Sent: Fri, Apr 30, 2021 9:00 am Subject: Re: [PSUBS-MAILIST] K-250 paint Yes you can paint the groove, but make sure the groove volume is still sufficient for the o-ring plus appropriate percentage.Check Parker O-Ring groove design chart.Hank On Thursday, April 29, 2021, 08:37:59 PM MDT, Jon Wallace via Personal_Submersibles wrote: Yes.?
