Sort of like this bow on view: /O\ where the / and the \ represent the thrusters canted 45 degrees out from the O which represents the pressure hull. This would allow the down wash to miss the horizontal thrusters while both "vertical" thrusters are heaving the sub upwards. And it would provide controlled translate (sidle) movement when the two "vertical" thrusters are powered to thrust one up and one down. Your ballast block will keep the sub from rolling and force it to translate sideways. This works very well for the DW2000's.

The fundamental question was whether to point them up or down. What I settled on was pointing both downward. Here was my reasoning: - I like diving the sub slightly positive, and use the side thrusters for depth control. Pointing downward, they are operating in their most efficient direction for the vast majority of the time. - Pointing downward the wash goes UP, which prevents stirring up silt. - By canting them outward you can crab by running them in opposite directions, gaining an extra degree of motion. Just two cents. If you prefer diving the sub negative you could point them both up. That would give you more power for reaching the surface in an emergency, but it would stir up silt the rest of the time. I have really huge MBTs for the emergency situations, so went for what I thought was the most convenient thruster direction in normal use. There's one more detail that I'll just have to test. When I dive Snoopy down on the side thrusters, she can get into really fast rotation because both props are turning in the same direction. I counter that by tilting one of the side thrusters slightly off vertical, but with the permanently mounted thrusters I won't have that possibility. It may not be an issue on the new sub, but if it is, I'm thinking I might have to install a little vane in the wash of the vertical thrusters to compensate. Or I could correct the rotation with the horizontal thrusters. Maybe even program that compensation into the speed controller logic. Practice will tell.

The fundamental question was whether to point them up or down. What I settled on was pointing both downward. Here was my reasoning: - I like diving the sub slightly positive, and use the side thrusters for depth control. Pointing downward, they are operating in their most efficient direction for the vast majority of the time.- Pointing downward the wash goes UP, which prevents stirring up silt.?- By canting them outward you can crab by running them in opposite directions, gaining an extra degree of motion. Just two cents. If you prefer diving the sub negative you could point them both up. That would give you more power for reaching the surface in an emergency, but it would stir up silt the rest of the time. I have really huge MBTs for the emergency situations, so went for what I thought was the most convenient thruster direction in normal use. There's one more detail that I'll just have to test. When I dive Snoopy down on the side thrusters, she can get into really fast rotation because both props are turning in the same direction. I counter that by tilting one of the side thrusters slightly off vertical, but with the permanently mounted thrusters I won't have that possibility. It may not be an issue on the new sub, but if it is, I'm thinking I might have to install a little vane in the wash of the vertical thrusters to compensate. Or I could correct the rotation with the horizontal thrusters. Maybe even program that compensation into the speed controller logic. Practice will tell. Best, Alec?

They had no data for other props, but say the motors run just as well in reverse. Replacing the plastic scimitars would probably cost you a bit of thrust in one direction, but you'd get a lot back the other way. It seemed like on balance that might be a reasonable trade-off. I did look for props at the time, but don't remember whether I actually found one. I'm betting if someone called Michigan or somebody they might find just the ticket. That would be cool, even if you had to build an adapter for the skinny shaft. I've got a wheelbarrow load of M-Ks sitting around. Maybe it's time to look into that again. I would really love to have something with a smaller diameter, maybe 3 or 4 blade to make up the difference. They'd have to be nicely balanced, however, as the M-K bearings are probably undersized for heavy props. Hmm.

The fundamental question was whether to point them up or down. What I settled on was pointing both downward. Here was my reasoning: - I like diving the sub slightly positive, and use the side thrusters for depth control. Pointing downward, they are operating in their most efficient direction for the vast majority of the time. - Pointing downward the wash goes UP, which prevents stirring up silt. - By canting them outward you can crab by running them in opposite directions, gaining an extra degree of motion. Just two cents. If you prefer diving the sub negative you could point them both up. That would give you more power for reaching the surface in an emergency, but it would stir up silt the rest of the time. I have really huge MBTs for the emergency situations, so went for what I thought was the most convenient thruster direction in normal use. There's one more detail that I'll just have to test. When I dive Snoopy down on the side thrusters, she can get into really fast rotation because both props are turning in the same direction. I counter that by tilting one of the side thrusters slightly off vertical, but with the permanently mounted thrusters I won't have that possibility. It may not be an issue on the new sub, but if it is, I'm thinking I might have to install a little vane in the wash of the vertical thrusters to compensate. Or I could correct the rotation with the horizontal thrusters. Maybe even program that compensation into the speed controller logic. Practice will tell.

And it would provide controlled translate (sidle) movement when the two "vertical" thrusters are powered to thrust one up and one down.

They have low DC voltages on solar powered units.I don't know enough about the magnetic coupling. It seems like it would becomplex & heavy. In our application, the propeller is pushing while going forward & pulling in reverse,so wouldn't there need to be large bearings on the coupler that would be exposed to?water?I am changing my mind all the time over my thruster preference.

This way you can pop out and pop in a new container and never have to deal with handling pellets or dealing with dust. The absorbent is sealed in a pre-engineered clear plastic 1 kg container that has mesh openings in the top and bottom. Each container is sealed in a plastic bag, maximizing shelf life.

What is a good particle size for a scrubber that will be using computer fans as the circulating fans? Seems like too fine a particle, the more air flow resistance.

This past summer dad and I were on the hunt for a missing outboard motor on a Canadian lake. We had a camera but no ROV. We actually ended up cutting a 15 foot sapling to use as a camera pole. Depth was only 17 ? 20 feet so the sapling worked pretty well as a camera handle from the boat (and we found the motor), but a controllable ROV would have made things much easier. It looks like those guys make some nice parts for ROV projects. The technical (software) aspect scares me a bit, but that's only because I am electronically challenged. ~ Douglas S.

The casing would keep the grit out of the windings. Then rinse out the motors with fresh water after each dive. I'm somewhat skeptical of the longevity and reliability of water flooded motors. Maybe have the motor assembly fresh water compensated i.e.: just flooded with distilled water similar to the oil compensated motors. No chance of polluting the environment.

One problem I can see with the exposed motor is that with all the water with sand, grit etc in it, flowing over the windings, it will wear down the windings thin coating.

This past summer dad and I were on the hunt for a missing outboard motor on a Canadian lake. We had a camera but no ROV. We actually ended up cutting a 15 foot sapling to use as a camera pole. Depth was only 17 ? 20 feet so the sapling worked pretty well as a camera handle from the boat (and we found the motor), but a controllable ROV would have made things much easier.

But it would be a known quantity& you could calculate?any power loss through electricity shorting through the water.The motors magnets would have to be coated to stop them rusting & you wouldneed to stop water wicking up the wiring by doing a good job epoxying it.I am just using an oil seal rated for 100ft & oil compensating. One of thetricks is to have the shaft under the seal polished, with no microscopic spiralsin the shaft that can cause the oil to pump out or water to pump in.Cheers Alan From: T Novak via Personal_Submersibles To: 'Personal Submersibles General Discussion' Sent: Monday, December 21, 2015 6:31 PM Subject: Re: [PSUBS-MAILIST] ROV opportunity #yiv0706546658 #yiv0706546658 -- _filtered #yiv0706546658 {font-family:Helvetica;panose-1:2 11 6 4 2 2 2 2 2 4;} _filtered #yiv0706546658 {panose-1:2 4 5 3 5 4 6 3 2 4;} _filtered #yiv0706546658 {font-family:Calibri;panose-1:2 15 5 2 2 2 4 3 2 4;}#yiv0706546658 #yiv0706546658 p.yiv0706546658MsoNormal, #yiv0706546658 li.yiv0706546658MsoNormal, #yiv0706546658 div.yiv0706546658MsoNormal {margin:0cm;margin-bottom:.0001pt;font-size:12.0pt;}#yiv0706546658 a:link, #yiv0706546658 span.yiv0706546658MsoHyperlink {color:blue;text-decoration:underline;}#yiv0706546658 a:visited, #yiv0706546658 span.yiv0706546658MsoHyperlinkFollowed {color:purple;text-decoration:underline;}#yiv0706546658 span.yiv0706546658EmailStyle17 {color:#1F497D;}#yiv0706546658 .yiv0706546658MsoChpDefault {font-size:10.0pt;} _filtered #yiv0706546658 {margin:72.0pt 72.0pt 72.0pt 72.0pt;}#yiv0706546658 div.yiv0706546658WordSection1 {}#yiv0706546658 Alan,How would you think a flooded motor in an ambient casing would work out??

I went with it because that's what it said in the Stachiw book. I tested my dome to 60 meters (200 feet) and although I couldn't see it, the rubber had obviously extruded quite a lot due to the amount of silicone squeezed out. Also, on my forward main tank, I have "windows" that are mounted on epdm seats. They are not pressure windows, just covers but they still need to seal the main tank. When I tighten the 8 bolts, the epdm extrudes maybe up to 5mm in places and I have to go around and trim it off. And they leaked before I sealed them permanently with sikaflex. Hank tested the neoprene\cork blend I sent him and it tested out much better. Im changing my dome mount to have that instead. Perhaps if you used a harder EPDM it might be ok? The one I have is 70 shore. I think a lot of people just sit the acrylic straight on the seat as well. I would probably just do that now with my dome, but I cannot as the retaining ring seal is designed for the 1mm gasket underneath. I am changing the seat for 1mm neoprene\cork gasket in a few weeks time.
