This came from my uncle who is a safety officer at a UK coal mine. Its all in current calibration etc. Anyway, I am using it really for the O2 sensor, however, it also has 3 other sensors for use in the mine. Carbon Monoxide, Methane and Hydrogen. (pity it doesn't have the CO2 sensor instead). After about 10 mins of diving, I was getting an alarm of 30ppm CO. This is the level deemed safe for an 8 hour exposure to CO. (Time weighted average). So, I wasn't particularly worried, but I am mystified where the CO is coming from, even a small amount. Battery pods are sealed shut. Could it be the scrubber? The absorbent is calcium hydroxide and lime. Any ideas anyone? Thanks James ? -------------- next part -------------- An HTML attachment was scrubbed...

Seriously though, I have found that hydrogen from the batteries will trigger CO alarms. We have a ratio somewhere which relates H2 with CO. So I think it must be coming from your batteries. My alarm was a Crowcon T4 and that alarmed. They must have to breathe somehow. Hugh From: Personal_Submersibles [mailto:personal_submersibles-bounces at psubs.org] On Behalf Of James Frankland via Personal_Submersibles Sent: Saturday, 3 October 2015 2:58 a.m. To: Personal Submersibles General Discussion Subject: [PSUBS-MAILIST] CO in cabin Hi All Last dive at the weekend I was using an MSA Orion plus, multi gas meter. This came from my uncle who is a safety officer at a UK coal mine. Its all in current calibration etc. Anyway, I am using it really for the O2 sensor, however, it also has 3 other sensors for use in the mine. Carbon Monoxide, Methane and Hydrogen. (pity it doesn't have the CO2 sensor instead). After about 10 mins of diving, I was getting an alarm of 30ppm CO. This is the level deemed safe for an 8 hour exposure to CO. (Time weighted average). So, I wasn't particularly worried, but I am mystified where the CO is coming from, even a small amount. Battery pods are sealed shut. Could it be the scrubber? The absorbent is calcium hydroxide and lime. Any ideas anyone? Thanks James ? -------------- next part -------------- An HTML attachment was scrubbed...

Like on compressors. Also helps longevity in salt water or corrosive atmosphere environments. The more air they have the more accurate because if there is no air bubble in the gauge the oil has to escape from the housing as the bourdon tube expands and the pressure of exhausting the oil will cause an inaccuracy. ( mostly in low pressure gauges). If they are full you end up with dribbles. They generally have a rubber bung on the top. Also if you fill it with oil and have it outside the sub you will have the same pressure inside and outside the bourdon tube and it wont measure.

We surmised that the purpose of the oil was as a buffer in case of explosion. So if you find an oil filled gauge it is not necessarily going to be full or pressure resistant.

Like on compressors.? Also helps longevity in salt water or corrosive atmosphere environments.The more air they have the more accurate because if there is no air bubble in the gauge the oil has to escape from the housing as the bourdon tube expands and the pressure of exhausting the oil will cause an inaccuracy. ( mostly in low pressure gauges).? If they are full you end up with dribbles.? They generally have a rubber bung on the top.? Also if you fill it with oil and have it outside the sub you will have the same pressure inside and outside the bourdon tube and it wont measure.? Hugh ?

In-Reply-To: References: Message-ID: Just a follow-up on this. While I'm pretty sure external oil filled gauges would work outside I find the oil doesn't like staying inside them, so I ended up bringing the gauges inside the hull. In the end, the majority of my air system is outside with just the gauges and the BIBS inside the hull. Apart from hull stops, the valves for operating the sub are outside and operated via mechanical through-hulls. It's not hard because there's just three valves total. In my experience most air leaks happen in those valves that are used routinely, as opposed to hull stops that are left alone. Even using top quality Swagelok valves, you sometimes have to tighten things up because a leak develops with use. One recent design change is that I'm trying air compensation on the thrusters again. I had originally made them oil compensated because the thrusters are jettison-able and oil compensation meant one less connection between thruster and hull, but I'll give air a try because, with big battery banks and freeboard, I expect this sub to rack up many more hours of running time than Snoopy did using thrusters just for maneuvering. Air compensation should mean less brush maintenance.

Date: Wed, 7 Oct 2015 08:29:07 -0400 Just a follow-up on this. While I'm pretty sure external oil filled gauges would work outside I find the oil doesn't like staying inside them, so I ended up bringing the gauges inside the hull. In the end, the majority of my air system is outside with just the gauges and the BIBS inside the hull. Apart from hull stops, the valves for operating the sub are outside and operated via mechanical through-hulls. It's not hard because there's just three valves total. In my experience most air leaks happen in those valves that are used routinely, as opposed to hull stops that are left alone. Even using top quality Swagelok valves, you sometimes have to tighten things up because a leak develops with use.? One recent design change is that I'm trying air compensation on the thrusters again. I had originally made them oil compensated because the thrusters are jettison-able and oil compensation meant one less connection between thruster and hull, but I'll give air a try because, with big battery banks and freeboard, I expect this sub to rack up many more hours of running time than Snoopy did using thrusters just for maneuvering. Air compensation should mean less brush maintenance. Best, Alec?

How long will the air last you in the escape pod? How large is your flood valve, & how long will it take to fill the sub to the point that the pod releases? I think you said you have a snorkel or breathing hole in your escape pod hatch. you could breath through this while the sub filled up with water, but it would be slowly pressurising your escape capsule. If the breathing hole in the escape hatch was oriented so that it was at the top of the hatch when in the attached position, then you could breath through it till the sub filled to about 1/2 way. I think you said you have a view port in the capsule, so you could possibly see the level the sub was filling to. If you breathed cabin air till the half way flood point you would pressurise the capsule to 15psi (33ft) & you wouldn't have any worries about decompression sickness at that stage.

You need a variety of tooling, both external tool holders and internal boring bars with a range of tips. All are tungsten or Silicon carbide these days. Tips for steel, stainless steel, aluminium etc are all different these days although you can get some general purpose tips. Forget dremels. Decide on a supplier, Iscar, Sandvik, Seco they are not cheap but it is easy to ruin a job halfway through. You will also need a range of measuring equipment, set of micrometers 0-150mm, Telescopic gauges, dial indicators, etc. not to mention drills and taps. Also get a copy of machinery?s handbook. To grind high speed steel (HSS) tooling you need to read a few books or do a course at tech. Book in for a machining class and you can do a lot of homers there without having to buy tools. Next thing you need is then a milling machine.

However I am not sure whether the extra pressure on the shaft would be?a problem or how much the H/P seal would impede the turning of the shaft.Also I haven't resolved how I am going to fit it. Options are to press fit it externally from the propellerend with or without a circlip to retain it. Or alternatively a bolt on plate to retain it.If I don't go with any form of retaining & rely on the press fit, am I best to glue it in?The other alternative is to fit it from inside the housing against a shoulder, with an internalcirclip retaining it.Any thoughts & opinions on this thanks.Alan -------------- next part -------------- An HTML attachment was scrubbed...

To: "Personal Submersibles General Discussion" Date: Sunday, September 20, 2015, 10:03 PM I have an interesting thing to think about and wondered if any of the PSUBS brain trust might have a suggestion. One of the simplifications on my new sub is that all HP air lines are external, aside from the BIBS (which is normally shut off anyway). Thus, I'm looking for a 3,000-4,000 psi gauge to mount outside a viewport, like in the Pisces photo that I'll paste below. In case my paste doesn't come through, it is the one at the top of the following article:?http://www.nytimes.com/2015/09/15/science/piloted-deep-sea-research-is-bottoming-out.html?_r=1 The first thing that came to mind was to use a SCUBA submersible pressure gauge, but the problem is these are normally 1 atm dry enclosures of limited depth rating. There is generally little information posted about how deep they'll go, but what I did find was mentioned 260 feet for the plastic ones and 490 feet for the brass variety. This is a 1,000 foot sub. The second idea was to use oil filled gauges intended for above-water use. But these generally have considerable bubbles in the oil, are not very good at keeping the oil inside, and have other hardware not intended to live long in sea water. Any suggestions would be most welcome!

When doing gas planning or recalculating on the fly, this can be a severe constraint. A full size gauge is much more accurate. Also, with a full size gauge, it is possible to read even in severely restricted visibility by pressing the gauge to your faceplate in front of one eye, and shining your light into your other (shut) eye. Button gauges preclude this action. Sean On October 20, 2015 9:30:45 AM MDT, via Personal_Submersibles wrote: >James, > > > >I wouldn't worry about it.

With the halves already welded, getting a caliper in might be tricky. Use a template to measure the out-of-round deviation in the worst possible plane. (Radius to match your design outer radius, subtending 120? of arc) If the radial distance between the template and the shell surface never exceeds 1/2 percent of the overall diameter at any point, then you're good to go. Just locate and measure the minimum shell thickness and use that measurement to determine the maximum allowable working depth. Looking forward, it's probably worth having a chat with someone at EE to explain why sphericity is critical, and seeing if they can accommodate you. They probably don't deal with many externally pressurised vessels, so e.g. additional press steps may be within their capabilities, but just not have occurred to them to do. Personally, I hate talking to people on the phone, so I create engineering drawings which are exhaustively toleranced, such that there is no way a supplied part could comply with the drawing and not be suitable.

If it works with Acrylic you can bet that it will do the same on Steel.
