I can't find the video of the steering one but I am using the same principle to open and close the flood valve for the VBT which I have attached.Hope this helpsRick On Fri, Jul 9, 2021 at 3:36 AM Jon Wallace via Personal_Submersibles wrote: I've thought about that as well but haven't got there yet.?

I would also love to hear a report from Alan James on the work he has done on a thruster built using brushless DC motor.? He is probably ready to get out of New Zealand for a while.? Likewise, I would love to hear a report from James Frankland on both his recent work on a emergency scrubber and also on the testing he did on his original scrubber, what he learned and what he has currently installed.? Long trip from England but you could go to Disney World if you made the trip. Alec Symth and Hank Pronk have done a lot of work on a DIY articulated arm.? Would like hear about that.? Steve McQueen has done an excellent job with his K-2500 build, The Great Escape.? I would love to hear a report about the build particularly the changes he made from the original plans.? Lastly, it has been several months since we have heard anything from Hank Pronk.? That is enough time for him build three subs.? Would love to hear and update on the E3000 as well as the new micro boat he build if he can stand to be out of Canada for a few days.?

Following the dive i did last week, i had a motor issue. The motor did not actually stop or fail, but during the dives it just didnt feel right. The positive wire going into the rotating penetrator would get hot after about 10 seconds of motor power. I could also hear a kind of electrical noise from within somewhere. So, the next day i took the motor apart. The oil (Silicone oil) was VERY black. I was expecting to see something had been rubbing, but i couldnt see anything. It all looked fine. I put it all back together and it runs fine in air. However, there does seem to be a louder motor running noise than the others. I am unsure what the issue is. My feeling is that its carbon in the oil, making it conducting and hence slightly shorting out, causing the heat on the cable. The other motor cable did not get hot, nor did the oil go black. Again, another video here. https://www.youtube.com/watch?v=v_VxVfhM9t8&t=2s Would appreciate any input. Im not sure what to do. Buy a new motor? Air compensate it?

After diving my boat with the same MK-101 motors, it is not uncommon to have some decolorization of the compensation oil. This is just small particles of the carbon brushes in suspension in the oil. This fluid is a dispersion and not a solution. The particles are in suspension in the low dielectric oil and not solubilized into the oil.? As such, the electrical conductivity of suspension should be that of the virgin oil.? If the electrically conductive carbon brush dust was solubilized into the oil, then it could slightly affect the conductivity.? To verify this, put some of the dark oil on a microscope slide and view under a microscope.? You should observe particles in suspension.?? ?On reassembly of the MD-101, I found the best way to deal with the brushes is to jam a thin piece of wood between the armature and permanent magnets so that the commutator is axially extended by about 1 cm.? Then pull the springs on the brushes off to the side so they are not engaged.? Slide the end of the housing that has the brushes into place then with a small screw drivers slide the springs back into place.? Then pull the wood wedge out and slide the armatures into its correct location.? Then, install the remaining end cap and insert the long retaining bolts and tighten being carful to centralize the fined section. As to noise and overheating issues.? I found these MD-101's are sensitive to radial alignment of the brushes, that is position of the housing that has the fin and brushes to the permanent magnet section of the thruster.? To experience this, loosen the two long bolts enough so that if you grab the fin on the body of the thruster, you can rotate the brushed end relative to the body. Put some painters tape on both the fined side and the body and with a pen draw a mark across both.? When you rotate the fin, these marks will show the misalignment.? ?While the motor is running, rotate the fin.? When the fin is perfectly centralized the motor has maximum speed but when you move off center it slows down slightly and makes a different sound.? By rotating you can hear when the motor in set to the sweet spot.? It may have been that the brushed end might have been slightly out of alignment during the dive. Best Cliff Sorry you will not be able to attend PSubs 2021 convention.? i would have liked to meet you in person.

Rick could be on to something with the bad connection on the positive. If it were giving intermitant power to the motor it could cause it to run rough & maybe the vibration from that is causing wear on the brushes and turning the oil black.?I would check that it is not something in the motor controller. Maybe run it straight from a battery & see if it sounds better.?The other thought was that I had heard of people adjusting the brush springs to give more pressure to avoid them lifting off their contacts due to the centrifical force of the oil lifting them. (as Emile mentioned)?Possibly the simplest thing to do is drain the oil again and run (for a short time) & see if the noise goes. If it does maybe a lower viscosity oil will help.?Good luck,?Alan On Wednesday, July 21, 2021, 05:25:02 AM GMT+12, Rick Patton via Personal_Submersibles wrote: James, you mentioned that one of the two wires is getting hotter than normal and the first thing that came to mind was that it didn't have a solid connection somewhere?

Message-ID: Hello, I signed up for a psubs membership and paid the $35 fee through paypal on 29/05/21. When I tried to use the UserID provided on the paypal receipt (UserID: 162221957946037) to sign in to the membership page on the psubs website I received errors stating that ?The information you provided does not match our records?. After numerous attempts at following the given instructions to sign in I emailed the website contacts, jon at psubs.org and publicrelations at psubs.org. I never received a response. I was going to initiate a fraudulent chargeback via paypal tonight when I searched the website again and discovered this possibly-alive email discussion group (the online forums being all but dead as far as I can tell). If anyone is out there, I?m interested in building my own submersible. I know it?s an achievable goal and there are like-minded individuals who have succeeded at this. The website being somewhat barren and dated, is psubs still an active organization? Would membership be beneficial in such a pursuit? If so, how does one contact the administrators to resolve issues?

In-Reply-To: References: Message-ID: <1600956569.1229001.1626857410775@mail.yahoo.com> Hello Quinn, sorry you've had trouble with the website and membership.? I am co-founder of PSUBS and it's administrator, and I will address your concerns.? This is a good opportunity to address everyone regarding some of the issues you've raised so I'm sending to the list at large.? Everyone should read this. The PSUBS Organization.We are alive and well, but PSUBS is an internet based organization ONLY with no official office or employees.? We do have a "leadership team" (posted on the website) which provides some elementary organizational structure to help guide the group, however a mailing list and facebook page represents the bulk of what PSUBS *is*.? PSUBS strength comes from the free flow of information obtained through our email based discussion group and our Facebook group. Membership.Membership is not required to navigate the website or participate in either the email discussion group or the facebook group.? Membership is primarily intended to facilitate binding the group in comradery in a way that elevates us from being "just a bunch of guys on the internet".? Fees are collected to finance conventions, research and development, and anything else we think will benefit the group.? We do have some discounts for members that are available from some vendors however "benefits" are not the primary reason we have a "membership". New memberships and renewals are processed automatically by software but unfortunately PayPal frequently changes the data it submits to us which ends up making the software fail.? Our membership processing software needs to be updated, but it's not a trivial task.? I have told existing members not to worry about renewing until I fix the software, and nobody has had their membership expired since the software problem was identified.? It looks like I forgot to hide the new membership signup page and I'm sorry it caught you. Contact me privately at jon.wallace at yahoo.com to sort out the membership fee issue. Barren and Dated Website.The website is primarily intended to be a repository of information that is derived from our discussion forums.? As most of us are aware, submarine fabrication as well as underwater exploration with a submarine is a "niche" hobby/market. There are not thousands of people building personal submarines, not even hundreds.? At any particular time there are perhaps a dozen or so people actively working on, or operating, a small personal submarine AND sharing that build or knowledge with the community at large.? As such, there is not a lot of daily, weekly, maybe even monthly movement in the community that necessitates updating the web site.??For the past 24 years, PSUBS has averaged about 200 people on our mailing list and that is about what we average for members on our Facebook group as well. AOPA has 350,000 members.? USPA has 37,000 members.? BoatUS has 700,000 members.? All three organizations have paid staff, large budgets, and thousands of members to keep their web content updated and dynamic.? PSUBS has me, no budget, and a handful of people that provide content beyond the discussion forums.? Therefore, some website content does tend to get dated such as "news", "events", and "press" because I don't have the time to query each member with "hey what's new today?"? Each Psubber should consider the website THEIR opportunity to submit content such as news or events that they either make, or hear about.? Perhaps with the advent of Facebook and the instantaneous ability to announce "news" and "events" to everyone at once, these type of dated pages aren't even necessary anymore.? Regardless, the bottom line is that we ALL have to help provide content to keep the website current and dynamic. Resources for the Novice.We have extremely valuable programs, calculators, white papers, spreadsheets, references, and design tools on the web site submitted by our members and other contributors, that are the core resources for designing, fabricating, and operating a small submarine.? All are far from being barren or dated.? As a self-admitted novice you will have much to learn, but most of us had a similar learning curve so you are in good company.? The discussion forums are your friend, whether you choose email, facebook, or both.? There are some valuable people on the email based group that do not contribute on Facebook, and vice-versa.? You shouldn't be hesitant to ask questions but at the same time you should also do some self-education for those "basic" questions you might have.?? Please note that the Facebook group is "private".? We allow anyone in, it was just set up that way originally (by mistake) and cannot be changed because of Facebook rules.

While most personal submersibles are not classed for this reason, it is generally recommended that you adhere to the spirit of the rules, if not the letter, as much as is reasonably practicable. Certainly, you should download and familiarize yourself with them, and then if you are going to deviate, make sure that those deviations are informed conscious decisions, as opposed to a consequence of ignorance.

Ive got some marvel mystery oil which i know people have used int he past. But im thinking of just ordinary hydraulic oil I use in the bobcat?

My first thought when rotating the motor while it was running and the noise was better when the prop was horizontal and worse when vertical was that the shaft was wobbling a bit when loaded with gravity which would bean the the bearings were bad or the thing the shaft fits into on the other end was sloppy. My concern on mine was to try and not weld anything to the housing as the heat would warp it possibly but it doesn't look like you've welded anything to it? Does your positive wire still get hot after checking the connection inside the housing?

But there are trade offs like more speed, less torque when you change the timing. So it may look to go better when not under load but perform worse under load.?You say you will give it a good run unfilled. Hope you are not going to run it out of the water for more than a minute or two!?I would stick with the silicone oil. Some of the other products destroy plastics, like wire insulation, over time.?Rick agrees with one of my thoughts that it could be a bearing.

But after 4 years I can tell you this, get the best medical treatment you can get and surround yourself with a team of experts to help you walk through this journey. Most importantly live each day to its fullest, surround yourself with those who make you the happiest and set aside those whom dont. There will be darker days, but move through them and find the light in the next. I wish you well my friend.
