Strange things have been happening lately with my emails. Yes you can poke the cable through the blueglobe cable gland, connect the wires, screw the blueglobe into it's fitting, then tighten the blueglobe around the cable. I have a heap of them, but they are the M16. I think we might have to go with the M32 rather than M20, to have a chance of pushing the wires as well as the connector through? the fittings opening,?before screwing in the blueglobe, if you follow. There is the option to buy them with an adapter. I think Jon is verifying whether there is a 2 terminal 50 amp SubConn connector. A 2 wire version would enable the wires +?joiner to fit through easier, however I like the 4 wire version as you can? use the other 2 wires?for your thruster temperature monitoring. we might be best to run the connector issues past Ken Martindale. He specializes in power electronics & has helped me in the past. If he's not listening in I could email him before we go out & buy. I had a look in an electrics store today & couldn't find a spade connector that could take 50 amps. I had that problem with my last sub. Nothing is simple. There are these gold plated high current cable joiners. http://www.jaycar.co.nz/productView.asp?ID=HC4064 They would probably have a lower profile than a spade connector of the same amp rating. They are about an inch long so you would need around 6 inches of shaft to fit them in if you connected 4 wires & had them staggered.? Alternatively you can slice & solder the wires together, but don't have the same convenience in swapping thrusters. Trying to think all this through as I have $1000- worth of SubConn connectors that have been sitting in a box for the last 3 years Will see what Cliff makes of all of this. He is hanging out with Kangaroos somewhere in the Aussie outback? at the moment.

The cable version including two feet of cable is around $115 (US). They don't have a two pin model strong enough for our needs but are going to look at whether they can make it or find one from some other source that will work. So the four pin solution that covers the power requirements of the MK101 would be right around $300 per motor if you used a threaded female bulkhead fitting for the hull and a cabled male fitting either potted or globed into the motor.

They were saying 10AWG max for the 4mm. But there is a 5.5mm version. http://www.hobbyking.co.uk/hobbyking/store/uh_viewItem.asp?idProduct=2087 The Subconn high power connectors have 8AWG on the cable end, which is 3.2mm diameter, so hopefully the 5.5mm will do. They are on ebay as polymax 5.5mm gold connectors & ship from the USA. I will try & find some locally.

They have a penetrator series which has a cable running off the penetrator, which would be ideal for fitting into the blueglobes. However I can't see any with the power we need. I will try & get hold of some of the gold connectors James suggested & some 8 & 10AWG cable to work out whether you could pull the wires + gold connector through the 32mm fitting the blue globe screws in to.

The cable version including two feet of cable is around $115 (US).? They don't have a two pin model strong enough for our needs but are going to look at whether they can make it or find one from some other source that will work. So the four pin solution that covers the power requirements of the MK101 would be right around $300 per motor if you used a threaded female bulkhead fitting for the hull and a cabled male fitting either potted or globed into the motor. _______________________________________________ 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...

While it would be nice to have a motor temperature sensor (3 wire RTD would be better than thermistor), for me?this?four pin?connector is? just too large and bulky for this application.? I feel like we are trying to make this connector work just because we have a discount?with SubConn connectors.? I am not sure this is the best connector for this application.? There are a lot of commercial thrusters operating at this current rating at higher voltages than 36v that don't look anywhere near the size of this connector.? I think we need to do a little research and look what?commercial thruster suppliers for ROVs are using for DC?wet matable connectors.? We need more options.? I agree the cost for these SubConn connectors looks good but only if it works and makes sense. Trying to standardize a connector for these MK-101 is proving to be more of a challenge than I anticipated particularly given the motor is pressure compensated and the differential pressure across the connector is less than 5 psi. Alan, I did see one of your notes brining up the issue of how do make up this bulk head connector on the MK-101 lower unit.? I have not done so yet on the MK-101 I have but it looks from the drawing?like it?would be?easy to pull the rotor assembly from the stator by removing two screws from the prop end of the unit.? I was planning on machining a bushing that would screw into the support boss on the thruster and screw the bulkhead fitting into this.? The drawing looks like it would be easy to push the bulkhead connector pigtails into this bushing, connect the wires to the existing wires by soldering and use shrink tubing to insulate?and reassembly the MK-101.? Won't know until I pull one apart.? Has anyone disassembled a MK-101 lower unit? Is it as easy as it looks?? The wires connections on the MK 36V motor controller are just simple 1/4" spade connections.??? I am wondering if they used the same spade connectors in the MK101 body?? BTY, these spade connections on the MK-36V motor controller don't look like they could handle 50 amps but MK has been using these successfully for a long time.? Go figure?

They were saying 10AWG max for the 4mm. But there is a 5.5mm version. http://www.hobbyking.co.uk/hobbyking/store/uh_viewItem.asp?idProduct=2087 The Subconn high power connectors have 8AWG on the cable end, which is 3.2mm diameter, so hopefully the 5.5mm will do. They are on ebay as polymax 5.5mm gold connectors & ship from the USA. I will try & find some locally.

It worked as you described but mine had a problem. The piston had a little path to leak a small amount of air into the equalizing chamber which was intended to keep any water out by virtue or the small rubber valve on the side of the regulator. The problem I had was that the rubber valve worked fine but the small leak path in the piston did not pass any air and thus no small bubbles. When diving to 150 feet the regulator thought it was at the surface and did not compensate for the depth and I felt I was sucking through a soda straw. Getting a new piston solved the problem but I never used the regulator at 150 feet again. Bottom line check and make sure the little bubbles are flowing.

It worked as designed, but still felt like sucking a golf ball through a garden hose when deep. That, and the stream of air from the bleed would and should be cause to scrub the dive under any other circumstance - it is a poor idea to train your buddies to ignore warning indicators.

I am feeling that our high amp draw problem is unique because we are going with Minnkotas. They are designed as an adjunct to a petrol motor on an outboard boat, & if they went to 48V or more to get the amps down, then the extra battery expense for the angler would cost them in sales. As said to Jon, I don't think the connector is going to be any smaller if we go to 2 wires, because they tend to pack out the cables to make them round & the connector heads are round.? To me the ideal set up would be a hull penetrator with cable running to a female connector. All one piece. Then a male connector that screws in to a pipe that in turn screws in to the stub of the motor. Alternative to a pipe could be a T connection that takes the compensating air line. The male connector would be wired direct on to the motor contacts. If you want to go cheap, simple, small; then have blueglobe cable glands on the motor & hull & a piece of appropriate cable between them. Both Carsten & Emile have them on either side of the hull penetration as a bit of insurance. Emile tested a Blueglobe to 3000psi before it started to extrude. But that solution doesn't work for David & I. I am away for a Month & won't be ordering anything till I get back. I think we aren't going to get any further till we pull a motor apart & maybe work backwards from there.

I have not had time to properly follow all the email traffic on this thread.? I hope to have some time to digest the thread when I get back home in about two weeks.? I did have a quick look at the Subconn HPBH4M?four pin connector that can handle 50 amps per pin?as well as?the note Alan posted on using two of these pins for a thermistor for motor temp.? While it would be nice to have a motor temperature sensor (3 wire RTD would be better than thermistor), for me?this?four pin?connector is? just too large and bulky for this application.? I feel like we are trying to make this connector work just because we have a discount?with SubConn connectors.? I am not sure this is the best connector for this application.? There are a lot of commercial thrusters operating at this current rating at higher voltages than 36v that don't look anywhere near the size of this connector.? I think we need to do a little research and look what?commercial thruster suppliers for ROVs are using for DC?wet matable connectors.? We need more options.? I agree the cost for these SubConn connectors looks good but only if it works and makes sense. Trying to standardize a connector for these MK-101 is proving to be more of a challenge than I anticipated particularly given the motor is pressure compensated and the differential pressure across the connector is less than 5 psi. Alan, I did see one of your notes brining up the issue of how do make up this bulk head connector on the MK-101 lower unit.? I have not done so yet on the MK-101 I have but it looks from the drawing?like it?would be?easy to pull the rotor assembly from the stator by removing two screws from the prop end of the unit.? I was planning on machining a bushing that would screw into the support boss on the thruster and screw the bulkhead fitting into this.? The drawing looks like it would be easy to push the bulkhead connector pigtails into this bushing, connect the wires to the existing wires by soldering and use shrink tubing to insulate?and reassembly the MK-101.? Won't know until I pull one apart.? Has anyone disassembled a MK-101 lower unit? Is it as easy as it looks?? The wires connections on the MK 36V motor controller are just simple 1/4" spade connections.??? I am wondering if they used the same spade connectors in the MK101 body?? BTY, these spade connections on the MK-36V motor controller don't look like they could handle 50 amps but MK has been using these successfully for a long time.? Go figure?

But there is a 5.5mm version. http://www.hobbyking.co.uk/hobbyking/store/uh_viewItem.asp?idProduct=2087 The Subconn high power connectors have 8AWG on the cable end, which is 3.2mm diameter, so hopefully the 5.5mm will do.

The first stage will adjust the pressure to 130 psi above ambient as the pressure increases in the hull when you flood it. Still you don't need a leaky regulator as it will be of no advantage to you in this situation. Better to maybe have the air on to it when diving in case you left the hatch open or a fire or something. Look forward to seeing it in person.

The first stage will adjust the pressure to 130 psi above ambient as the pressure increases in the hull when you flood it. Still you don't need a leaky regulator as it will be of no advantage to you in this situation. Better to maybe have the air on to it when diving in case you left the hatch open or a fire or something. Look forward to seeing it in person.

Sherwood first stages use a dry air bleed system which constantly vents a miniscule amount of gas, instead of allowing seawater into the balance chamber. While this works, it makes it difficult to distinguish the bleed from a problematic leak.

On air, narcosis which is significant enough to impair judgement or behaviour is a possibility even shallower than 100 fsw, and almost guaranteed below 150 fsw. Air reaches a PPO2 of 1.6 (the recommended maximum) at 218 fsw, so beyond that, you have to reduce oxygen and increase inerts. With helium, you think more clearly, but because it has a fast uptake, you incur decompression obligation faster than with nitrogen. Nitrogen gives you a better shot at avoiding bends, but impairs your judgement in an emergency situation when you might need it most. Ascent rate is an issue too, as ideally you would want to escape quickly to minimize your exposure time, and ascend rapidly from depth, but slow yourself as you approach the surface to allow an opportunity for any dissolved gas from depth to escape your body safely. The bottom line is that drowning is unsurvivable. DCS in many cases can be treated, so it makes sense to get yourself to the surface as rapidly as possible. If I were selecting a gas for escape purposes, I would mix for a maximum PPO2 of 1.6 at the maximum anticipated depth, because toxicity onsets rapidly and convulsions are debilitating, so you don't want to mess around with too much oxygen. I would also accept a higher nitrogen content than I might for diving, with the understanding that effecting the escape should be quick and get me to lesser pressures rapidly, and I would flare my body or otherwise attempt to slow the ascent somewhat as I approach the surface. Also, I don't know how practical it would be for a small sub with limited internal space, but the Mustang SC2000 suits look like a sexy piece of kit to have.

We did ascents both with the Steinke Hood and with just the life jacket. Both systems had 2 psi pressure reliefs built into them. Ascent time from 50 ft was 8 seconds, I don't remember what the time was from 100 ft but it was something like 15 seconds. We had a bit of bottom time since we were doing it in small groups. The divers that worked in the tank just used a mask and fins. They worked the whole tank just ducking into the open bells on the other side of the tank for air. They kept the water very warm for them since they were there for hours.

All PLCs can connect to these. Better accuracy and span than a thermistor. I use these on the R300. Do a search at McMaster Carr on RTD probes for many options.

Wow warm water, yikes. I had to install a marine engine compartment exhaust fan in Gamma. I need air circulation and a way to cool the sub down when working on it. The temp hits 28C inside and the fan cools it down real fast. I had it running at the lake today to cool it down when getting ready to start diving. Works great! noisy but works real fast so who cares about the noise, John, I agree it is not much difference in pressure, but it is very uncomfortable for my ears. Also I am new to life support operations and I like to keep her on the mark.

I also find it more fun and interactive than using a VBT. The trick seems to be, to have the weight of the sub in the sweet spot. I just got lucky and had the weight perfect right from the start. I mean I had it calculated just perfect :-) Now that I know this will happen, I will simply turn on my emergency air supply and give a little shot of air to return to my set point. When the cabin pressure has risen in past tests, I hit the air compressor for a couple of seconds and it is corrected right away. The onboard air compressor was a savior at the lake. I was able to refill both hp tanks at the dock. I used four tanks of air. I had zero leakage from windows ect. The hatch seal leaks at the very start but stops right away when I dive. The hatch dogs need to be built up with some weld. The dogs are new but the CT has grooves worn into the steel from being closed a million times or so.

I mean I had it calculated just perfect :-) Now that I know this will happen, I will simply turn on my emergency air supply and give a little shot of air to return to my set point. When the cabin pressure has risen in past tests, I hit the air compressor for a couple of seconds and it is corrected right away. The onboard air compressor was a savior at the lake. I was able to refill both hp tanks at the dock. I used four tanks of air. I had zero leakage from windows ect. The hatch seal leaks at the very start but stops right away when I dive. The hatch dogs need to be built up with some weld. The dogs are new but the CT has grooves worn into the steel from being closed a million times or so.

We unloaded the sub at the top of the ramp, then rolled the cart down the ramp with the sub on it. The distance of the roll was about 30 feet. The cart did not travel straight and would veer off coarse. I was very carful to have the wheels aligned for this when I built it but??? To load the sub, we had to push the cart into the water deep enough to load because the ramp in this lake is not steep enough and the cart not heavy enough to roll on its own, like it does in other lakes. It was quite frustrating. I will keep the cart for super shallow launches and icy conditions.

You asked the right questions to begin with, evaluated knowing what you know, added the data that the Nektons have done +12K dives like they are, and went to see. As they told me once at Gunsite Ranch in Arizona, we are not here to teach you to shoot. We are merely asking that you suspend what you know and let us teach you something new. Then you can make up your own mind.

After just one day, I feel like a real pro. To think I was so against the idea. I am glad I trusted the design and left it original. In the future I will listen, lol, well try to.

The MBT air trick is like magic, right? The old Perry boats had very elaborate variable ballast systems, custom under deck tanks, 4-piston pumps, all SS valving and plumbing, etc. And of course we used it to find that sweet spot you mentioned and then pretty much ignored it afterwards.

I also find it more fun and interactive than using a VBT. The trick seems to be, to have the weight of the sub in the sweet spot. I just got lucky and had the weight perfect right from the start. I mean I had it calculated just perfect :-) Now that I know this will happen, I will simply turn on my emergency air supply and give a little shot of air to return to my set point. When the cabin pressure has risen in past tests, I hit the air compressor for a couple of seconds and it is corrected right away. The onboard air compressor was a savior at the lake. I was able to refill both hp tanks at the dock. I used four tanks of air. I had zero leakage from windows ect. The hatch seal leaks at the very start but stops right away when I dive. The hatch dogs need to be built up with some weld. The dogs are new but the CT has grooves worn into the steel from being closed a million times or so.

It is powered off batteries. I am very pleased with the battery performance, I ran the entire day off one bank and the voltage only dropped slightly by days end.

The set up is very simple, I run the hp line off the compressor to my main hp tank with a hp valve. To fill the spare tank, I have to undo the lines and switch them. Normally I would never deplete the spare tank, so I don't mind switching the lines the odd time. Just keep watching ebay for scuba compressors, they show up pretty often. I have an inline hp filter that I made from a hydraulic cylinder, it has activated charcoal and tampons in it to catch the moisture. Just in case I need to breath the air. Also I am using the proper oil in the compressor for breathable air. A picture will not work because the compressor is buried under cables etc in the back of the sub. The compressor is also handy for correcting an over pressure in the sub. I will be doing more dives in a few days, and plan on testing the compressor to surface. I will surface until the hatch is above water with air from the hp tank, open the hatch vent valve, then use the compressor to finish surfacing. The idea is to save battery life, the compressor puts out very well at low pressure and requires a lot less power. It might be slow and to noisy, it is worth a try though.

These little boats all have multiple means of surfacing and would not require you to flood and escape if you had a loss of power, ran out of HP air, etc. Its really only entanglement that I see as likely to cause you to bail. However, if you don't rip yourself free with MBT blown, thrusters pushing, and emergency weight dropped, then you would probably need an awfully big lift bag to make a significant difference to the situation. Or think of it another way... you already have lift bags, they are called MBTs.

DW2000 would be lucky to have 100 lbs of buoyancy (figuratively speaking). They work on plan B. Another side of the problem is that if you are caught by the tail and you blow tanks then you have to see that the tanks will work at a reasonably steep angle. I am planning on putting in a couple of emergency bags but I think we are overdoing that side. As they say "Plan the dive and Dive the plan" should keep you out of most trouble with the emphasis on what if S--- happens. With the advent of Kevlar fishing gear and ropes the danger is increasing. I plan on keeping in touch with the tech divers who have the ability to rescue me at depth. They can do 400 ft but would have to be brave to do 600 ft. However if you need extra ballast then you can do worse than adding Air cylinders.

These subs were of the very best quality that George ever produced, and his last personal sub was built with that sort of mindset. It was a very nice K-350. The owner is asking $17K currently, which is probably what he paid for it. Even so, if it's clean, then it's a steal.

The sub was very stable when surfaced and very stable when submerged. The transition while submerging was very wild because the water can rush from one end to the other in an instant. Very scary :-) On Alec's suggestion I compartmentalized the tanks and it was a gigantic improvement.

You just need to check the material specifications to make sure the product is suitable for the depth you want it for. Do you have the Stachiw book on acrylic? If not, ask someone with the book what specifications you need to know, & secondly once you know the relevant specs, ask what depth your material is suitable for. Or if it can wait, ask Phil.

Maybe that's a good guess, but..... I will say that an ammeter in the boat is a good thing.

The problem with WD40 is that it is a solvent that damages plastic and rubber components within the motor. Alec Smyth did a lot of testing on various oils. The last I knew the medium of choice was Marvel Mystery Oil. It's safe for the seals, etc., and has a lower viscosity than any straight mineral oil. For thrusters, comparative amp draw at a given RPM (with associated heat build-up) is probably more significant than drop in maximum RPM since we're not generally operating at maximum. That might not be true when you're using the motor to operate a pump. Jim In a message dated 8/30/2014 5:51:09 A.M.

Flash points below 100 F are "flammable" and flash points from 101 to 200 are "combustible." Proprietary spec sheets will often say flammable even when in the combustible range. Don't know why; might have something to do with lawyers. Veterinary supply stores are the only ones I've found selling unscented mineral oil in small quantities (1 gallon), and I have no idea of the viscosity. I often see a substantial variation in the quoted viscosity of a product. Again, not sure why. In lubricants the viscosity can double with as little as a 10 degree F change in temperature. If I were trying to choose between MMO and a very low viscosity mineral oil, I'd probably test viscosity of each at 40, 70, and 100 F. Or I'd just ask Alec and go with his recommendation.

But you can get lower viscosity than what I use. http://www.penreco.com/images/spec-sheets/White_Oil.pdf Brian --- personal_submersibles at psubs.org wrote: From: hank pronk via Personal_Submersibles To: Personal Submersibles General Discussion Subject: Re: [PSUBS-MAILIST] rpm Date: Sat, 30 Aug 2014 09:49:41 -0700 Jim, Thanks' I was going to ask what is the preferred oil. I have been using WD40 for some time now and found no problems. I did have a clear tube running to a motor and it hardened. Other than that the motors I have are on their third sub and still working. I will make the switch to marvel mystery oil since I am now out of WD40.

The problem with WD40 is that it is a solvent that damages plastic and rubber components within the motor. Alec Smyth did a lot of testing on various oils. The last I knew the medium of choice was Marvel Mystery Oil. It's safe for the seals, etc., and has a lower viscosity than any straight mineral oil. For thrusters, comparative amp draw at a given RPM (with associated heat build-up) is probably more significant than drop in maximum RPM since we're not generally operating at maximum. That might not be true when you're using the motor to operate a pump. Jim In a message dated 8/30/2014 5:51:09 A.M.

Maybe that's a good guess, but..... I will say that an ammeter in the boat is a good thing. You can keep an eye on things, and if it goes UP at some stage, you would suspect a thruster issue (a tangle, or a bearing failure or whatever). All it takes is an appropriate shunt and a gauge (in my pre-digital steampunk mind). Okay, thanks anyway. I was curious, that's all.

I am using a trolling motor to drive the pump. A while back there was a question about rpm drop when a trolling motor is filled with oil. I bench tested that today, and the motor runs at 2,000rpm stock and 1,800 rpm full of WD40.

Am currently staying on Koh Tao Island in a bamboo hut on a cliff, with the most amazing diving I've seen, just below. There is a twenty foot drop off from the steps at the base, in to warm water, caves, canyons, coral & tropical fish in abundance........ This is submarine paradise. Really enjoyed catching up with people at conference. Could have spent a week listening to Phil talk. We are really fortunate that he gives us this time. He even shouted us all lunch.

I notice that your exhaust bubbles enter the shot a lot, and I was wondering if the regulator second stage you are using has a decent exhaust tee, or if you could potentially construct some sort of bubble diverter into the camera mount? Thanks for taking that video, though. I didn't realize that you managed to get some. The one descent I made that day was like diving in pea soup.
