Emile Van: Personal_Submersibles Namens Alan James via Personal_Submersibles Verzonden: maandag 28 december 2020 19:41 Aan: Cliff Redus via Personal_Submersibles Onderwerp: Re: [PSUBS-MAILIST] Scrubber design and materials Following this discussion with interest. Emile I thought had an axial type scrubber that held something like 10lb of absorbent. This would require a lot more power to move the air through maybe 1ft of absorbent, whereas David has a radial scrubber that only needs to push air through a 2" section of absorbent. Some good thoughts on power consumption under load Cliff. I wonder if the load increases as the absorbent is spent & becomes more soggy. Ie. is there more of a load toward the end of the dive than at the beginning. I am wanting to go with 2 smaller axial scrubbers, mainly to keep the size down. Am thinking of using an oversized axial fan to keep the noise down, and have automated speed control based on the CO2 level.

You would need to look at the head curve on the datasheet to determine the actual flowrate through the fan/scrubber. It would be substantially reduced due to the pressure drop through the CO2 absorbent section. Also to meet ABS rules, you need to size this unit so the that the current draw is not so great as to pull the emergency battery down before reaching 72 hours of life support. On my boat, the hotel load is about 1.5 amps (life support and comms only). The emergency battery has a capacity of 110 Ah at 24V so a 1.5A hotel load will last 73 hours.

My update is relatively simple. Shackleton has the arm and also I put in a "diver recall system" from OTS. It's a hydrophone that allows you to listen to ambient sounds, as well as functioning as a speaker to communicate with nearby divers or subs that have no comms gear. Basically it's a 120 watt speaker in the water, and is supposedly audible for 100m with voice and 300m using a tone. We shall see, however, how well it works. The challenge is that, in listening mode, it hears its own speaker in the sub and if the volume is turned up too much you get a feedback loop (a very loud screech.) I could solve the issue by wearing headphones in the sub, but prefer not to do that. After lots of experimentation, I've got to where I can run the volume at 75% without triggering feedback, but that is while sitting on the driveway. As water conducts sound much better than air, I expect ihe feedback to happen earlier in the water. I'm now building a slurp gun (suction sampler.) We have an Innerspace Science expedition planned to Sebago Lake in Maine, together with Brian Hughes and his sub Harold, in collaboration with St Joseph's University of Maine. It's just a matter of when Covid will allow us to go, with the expected date being in the late summer or early fall. Before that, I will need to do a depth test, most likely in Seneca Lake.

Judging by the PSub list traffic, it sound like Rick Patton is getting close so sea trials on his new boat.? Rick, can you give us an update.? I know Steve McQueen has been busy digesting the learnings from his first dive of The Great Escape last summer.? Steve, what's new with The Great Escape? When does she go back in the water? Brian Cox I know has been busy.? We have all been enjoying his video post of dunk test on his boat.? Brian, what's the latest?? I know that Hugh Fulton is back on QSub with a new electrical guy on board that is bringing some energy to the build.? Hugh, any updates on QSub?? New Zealand in the summer might be fun!

PC2021I am more than ready to plan the next PSUBS convention and participate in some expeditions as well.? I am as hopeful as you that the Covid-19 vaccines will start to hit the masses and free us up to gather together again.? It sounds like we have lots of information to share so the time is right to plan this.? I'm open to location and the Keys are a great place to get some salt water experience.? Not sure if Doug is still reading mail or just monitoring the FB page, but we should coordinate with him if we do 2021 in the Keys.? I will be in the Keys starting next week (Jan 10) until sometime in May.? Back to NH for the summer, then back to the Keys after Labor Day (beginning of September) until December. I am mobile and ready to support expeditions as well.? Not retired yet (close) but have lots of vacation time accrued so ready to travel.?? ProjectsSCM?(Submarine Control Manager)I am at the tail end of my SCM electronic project which combines my SEM (Submarine Environment Monitor) design with thruster control and power monitoring.? My goal is to complete this over the current winter months and declare it "DONE" by spring.? I am looking forward to presenting this project to the group at our next convention. SEMjRThe junior version of my Submarine Environment Monitor was released to the group in December and is available on the website.? I was happy to see that at least one fellow psubber has picked up on it and begun fabrication on the project.? I'm looking forward to his progress on it and getting feedback. K600Aquatic is still sitting in the driveway awaiting retrofit.? This past summer I thought I had sandblasting worked out and even purchased paint from Sherwin Williams to recoat it, however that sandblaster fell through and the work was not performed.? Living in a rural area I have found it difficult to locate a blaster that wants to take on this project.? I have concluded that I will likely need to trailer the K600 to Portsmouth or Boston to find a shop large enough to lift, blast, and paint the sub. K600 TrailerThis work is complete and although I am happy with the results I would not recommend retrofitting an aluminum boat trailer for a submarine.? Too much work, too expensive, pain in the ass.? Steel is your friend. Jon -------------- next part -------------- An HTML attachment was scrubbed...

Hopefully they will be easy to follow! As for effort, I really don't know. Hank is a fast builder and makes something like this in a few days, but for me it's more like a couple of months and making the drawings was as much work as making the parts themselves. The files include a bill of materials so you can see the cost of everything. The big variable is how much you pay for the actuators, as there is a vast difference between what they cost new and what you can sometimes pick them up for on eBay or on Amazon open box specials. I'm guessing I must have spent about a grand total.

A list of 11 sub and 5 trailer items that needed attention/improvement was also identified and are partially completed. I am also working on checklists and procedures as a result of lessons learned. I anticipate more local testing this spring to verify resolution of these identified issues followed by incremental depth tests. Depth testing will be followed by an upgrade of the thrusters and motor controllers bringing the sub to a fully operational status. Once operational I am planning to spend some extended time exploring @: http://www.michiganpreserves.org/whitefish.htm I am also outfitting a 26' support boat to act as a tow vehicle and operational platform for near shore diving operations. In addition I am planning to add to my podcast topics in 2021 interviews with members to discuss their design philosophies and individual projects.

We do not have any cases in the wild. So, i have been able to do a couple of dives last summer. Currently continuing with the rebuild of Skadoc. Slow progress, but i am on the go now each week with no other non sub related projects getting in the way. Also doing my vlog to record progress. A bit short on content for now, but getting there and i am trying to get better at the video editing etc. https://www.youtube.com/watch?v=RGJo0Iv2nAU Battery pod 2 is nearly complete and I am building a gantry to get Skadoc lifted enough to get the pods on. Then i should be getting somewhere. Just thrusters, engine, ballast, drop weights, kitchen sink to go. Ive also ordered a new trailer to replace the gigantic one that Jodie B sits on and takes up half my workshop. Been waiting 4 months for delivery due to Covid.

You been busy.?? On the Psub 2021 Convention, I for one like the idea of having it Islamorada, FL particularly if we can get the Shur's onboard to use their place as a base.? Even though we are a ways out, I think it would be good to nail down a tentative date so people can get the date on a calendar.? The other thing we need is to get at least one of our members to commit to bringing their boat to anchor this part of the convention.? The more boats the better but we need at least one boat that can take passengers.? I for one would love it if Alec could tentatively commit to bringing Shackleton.?? Thanks for your willingness to coordinate the convention.? This is a big commitment. Cliff PS: I like your idea about getting some of our members to give an updates on their builds.

PC2021I am more than ready to plan the next PSUBS convention and participate in some expeditions as well.? I am as hopeful as you that the Covid-19 vaccines will start to hit the masses and free us up to gather together again.? It sounds like we have lots of information to share so the time is right to plan this.? I'm open to location and the Keys are a great place to get some salt water experience.? Not sure if Doug is still reading mail or just monitoring the FB page, but we should coordinate with him if we do 2021 in the Keys.? I will be in the Keys starting next week (Jan 10) until sometime in May.? Back to NH for the summer, then back to the Keys after Labor Day (beginning of September) until December. I am mobile and ready to support expeditions as well.? Not retired yet (close) but have lots of vacation time accrued so ready to travel.?? ProjectsSCM?(Submarine Control Manager)I am at the tail end of my SCM electronic project which combines my SEM (Submarine Environment Monitor) design with thruster control and power monitoring.? My goal is to complete this over the current winter months and declare it "DONE" by spring.? I am looking forward to presenting this project to the group at our next convention. SEMjRThe junior version of my Submarine Environment Monitor was released to the group in December and is available on the website.? I was happy to see that at least one fellow psubber has picked up on it and begun fabrication on the project.? I'm looking forward to his progress on it and getting feedback. K600Aquatic is still sitting in the driveway awaiting retrofit.? This past summer I thought I had sandblasting worked out and even purchased paint from Sherwin Williams to recoat it, however that sandblaster fell through and the work was not performed.? Living in a rural area I have found it difficult to locate a blaster that wants to take on this project.? I have concluded that I will likely need to trailer the K600 to Portsmouth or Boston to find a shop large enough to lift, blast, and paint the sub. K600 TrailerThis work is complete and although I am happy with the results I would not recommend retrofitting an aluminum boat trailer for a submarine.? Too much work, too expensive, pain in the ass.? Steel is your friend.

SeaQuestor: The foam exoskeleton is nearing completion which is currently wrapped around the hull. I should be ready to start the first layups of fiberglass this month subject to the weather. The rear vectored thrusters and controls are complete and operational. The wing thrusters support brackets are being fabricated and will be installed once the foam is removed. The main pilot console is completed and wired ready for final install. Sandblaster is secured ready for the hull to be delivered next month. The big challenge currently is finding a fabricator for the pair of 30" acrylic domes, with a reasonable expense. Is Gregg Cotrell still around? Otherwise I might be building an oven. VAST K250: I acquired this sub from Mark Ragan in August and it was delivered just before the fires. Currently I have replaced all wiring and thruster controls with a 6way switch each (4 forward, 2 reverse). I have built a new main power console which includes switches for interior and exterior lights, fan and scrubber fan, accessory power supply outlets for 12v and USB. Installed new voltage gauge for battery status, and Hawkeye digital depth gauge with both interior cabin temp and water temp. Installed Garmin SV97 sonar and sidescan sonar. Installed new hatch dog bolts. Built and installed a bouy with depth indicators and is deployable from the magnetic mounts. Installed new OTS diver unit and transducer for comms, and a secondary system which is the OTS Magnacom unit which has two channels. This unit has yet to be field tested to see if in fact it can reach 3000 ft. and is planned to be used in the event there is ever an event that needs more power for the comms transmission. I have completed the scrubber build project and will be installing it this weekend. Currently I am building a mech arm based upon Alec's design from his shop dwgs.The mount to the sub will be a custom design with a deployable bolt. I will be posting images as the build comes together. The hope is to have a first in water sea trial for balance and controls later this month subject to the weather now that the boat is fully registered with its own hull number and cf number.

I would love to hear a short update on Psub community builds. I have heard bits and pieces on a number of builds but would love an update from members on progress. I know Jon Wallace is working away on his boat electronics and his trailer. Jon, where are you overall on the build? Alec has Shackleton ship shape and has a new articulated arm to play with. I think he is pretty far along on a 2021 InnerspaceScience.org 2021 Expedition. Alec, any updates? Gary Boucher has retired from LSU faculty and is busy on a retrofit of Vindicator. He is changing out the drive train to articulated Minn Kotta thrusters, putting the boat on a diet to drop weight and rebuilding the electronics. Gary what else have you planned for Vindicator? Alan has been busy on custom thrusters for his boat. Alan, what the status on the thrusters and what else you been up to. David Colombo, how is SeaQuestor coming along? What's next? And were are you on getting your new boat ready to dive? Carstan, Emile, what's new with your boats? I was sorry that Covid 19 wiped out the European Psub events you guys had planned. Judging by the PSub list traffic, it sound like Rick Patton is getting close so sea trials on his new boat. Rick, can you give us an update. I know Steve McQueen has been busy digesting the learnings from his first dive of The Great Escape last summer. Steve, what's new with The Great Escape? When does she go back in the water? Brian Cox I know has been busy. We have all been enjoying his video post of dunk test on his boat. Brian, what's the latest? I know that Hugh Fulton is back on QSub with a new electrical guy on board that is bringing some energy to the build. Hugh, any updates on QSub? New Zealand in the summer might be fun! >> >> New year is time for goal setting and planning. I for one would love to know what the member community is up to. Jon, any thoughts on the 2021 PSub Convention? I think we should move forward on this with the anticipation that the Convid 19 vaccinations will be successful and at some point we will regain a degree of normalcy. What about Islamorada Florida this summer or fall? >> >> I will give you a brief update on my Psub work. The R300 is fully operational and I am just waiting for the dive season to start. I changed out the pressure compensation on the thursters from air to oil so am anxious to see how the thursters work. I have also started design work on a new boat I am designating the R800. It is a low cost atmospheric diving suit (ADS). The design depth of the boat is 800 feet. I am trying to make it ABS compliant as much as possible. Preliminary engineering is almost done. Weight and balance calcs as well as preliminary FEA work on hull and pods are done. Am currently working on detailing the electrical boxes and hull penetrations. Alec build a OP valve for me that I am currently testing to document it's cracking pressure and overall depth rating. I hope to complete detail engineering by this summer time and start the build. >> >> Cliff >> >> >> >> On Sunday, January 3, 2021, 03:40:59 PM CST, via Personal_Submersibles wrote: >> >> >> Alan, >> >> Axial scrubber, radial fan.. >> >> Emile >> >> Van: Personal_Submersibles Namens Alan James via Personal_Submersibles >> Verzonden: maandag 28 december 2020 19:41 >> Aan: Cliff Redus via Personal_Submersibles >> Onderwerp: Re: [PSUBS-MAILIST] Scrubber design and materials >> >> Following this discussion with interest. >> >> Emile I thought had an axial type scrubber >> >> that held something like 10lb of absorbent. >> >> This would require a lot more power to move the air through maybe 1ft of absorbent, whereas David has a radial scrubber that only needs to push air through a 2" section of absorbent.

I have a ton of things coming this year, which due to Covid will all surely be looking at late summer or fall, but I'll certainly prioritize attending a convention with Shackleton and move pretty much anything around to suit if I have the ability to do so. I'm hopeful Shackleton should now be able to take passengers on and off in the water, but I still agree having a barge with a crane would be key for almost any other sub. I can offer a good Zodiac as a tender, but it isn't a tow boat.

I have a ton of things coming this year, which due to Covid will all surely be looking at late summer or fall, but I'll certainly prioritize attending a convention with Shackleton and move pretty much anything around to suit if I have the ability to do so. I'm hopeful Shackleton should now be able to take passengers on and off in the water, but I still agree having a barge with a crane would be key for almost any other sub. I can offer a good Zodiac as a tender, but it isn't a tow boat. Best,Alec?

Considering the above date considerations, I would suggest October. Can we meet here in summer? Yes, but it will be hot. Water temps will be high 80's to low 90's which means high cabin temps in any submarines that are diving. For those flying, Ft. Lauderdale is two hours by car, Miami is 1.5 hours by car.

We will need a solution for bringing subs to destination dive spots. Perhaps we should try to hook up with a scuba/snorkel charter at one of the reefs which would provide for some interesting photos.

You could probably get 12 hours per day of diving, barring bad weather.

That is when it's not in a divers mouth or in your case attached to a system it can pressurise. So mount it vertically or with the diaphragm to the top. If you narrowed the extentions to the exhaust ports you would get a bit of back pressure that would stop any free flow. All your system should be at the ambient pressure the diaphragm is exposed to. So if its 1ft down in a bucket you should have 1/2 psi in the system that is out of the water.?Alan On Saturday, January 16, 2021, 01:16:11 AM GMT+13, hank pronk via Personal_Submersibles wrote: Emile, thank you, I did some testing yesterday with the regulator in a pail of water and connected to the arm actuators. ?I removed the vent plug from the actuator to see how much air flows through the actuator. ?Only a very small amount of air comes out the vent port before the regulator free flows. ?I think that is due to the length of the small air lines to the actuators, plus there are wires in the hoses. ?I then put extension tubes on the regulator vent ports and tried it. ?There is a significant improvement in air flow coming out of the actuator vent port. ?The question is, do I need the increased air flow? given the amount of things being compensated.Hank On Thursday, January 14, 2021, 11:21:55 PM MST, via Personal_Submersibles wrote: Hank, ?

My apologies that it has taken so long, unacceptable on my part. Thanks to both Cliff and Jon for starting these threads on project updates and a possible PC '21. I'll take this opportunity to share an update of my own, sorry that it's going to be rather long-winded. For those who might not have heard through the Facebook grapevine, my family has experienced a bit of bad luck lately (well actually a lot of bad luck, haha). During a ferocious storm back in the summer of 2019, our family home was struck by lightning! The smell of ozone and burned wiring filled the whole house but we checked scrupulously and there was no fire. We had to replace our TVs, computers and other appliances because the electricity from the lightning seems to have entered the house through the power main. We also inspected and replaced as much wiring as we could, but wiring behind walls and in the ceiling proved nearly impossible to replace so we left it alone. Apparently that was a big mistake because a few months later in October of 2019, the house caught fire and, for all intents and purposes, burned to the ground. Some of the structure was salvageable but much of it was lost. We are very fortunate that we also own a sort of 'guest house' on the same property that was untouched by the flames, so we've been living in this little place for the past 15 months now as the house has been getting gutted, redesigned and now rebuilt. Unbelievably we suffered a second, completely unrelated, fire on the same property this July, 2020. A tree fell in strong winds bringing a 19.9KV line down onto our detached garage. The metal garage became electrified and started emitting sparks. This eventually caught some fireworks on fire that went off and set the whole building alight. After the house fire we had made extra room in this garage for the storage of any salvageable articles from the house, so the garage was loaded to the gills with valuable stuff and unfortunately it was all lost to smoke, fire, water or some combination thereof. Several fire departments responded immediately but there was little to be done before the electric utility killed the line and for some reason that took the better part of an hour. It was painful for us to watch as the garage went up in smoke and flame with the firemen standing by but unable to safely fight the fire. Luckily in the lightning strike and both structure fires, no lives were lost and in the final analysis that's all that matters. But throw in the pandemic that we've all been dealing with and this past year has been no picnic at the beach! Starting in the fall of 2019, right before the house fire hit, I had embarked on the project of a lifetime - building a light airplane. I rented out a business-jet hangar at my local airport and began quick-build construction of Zenair Ltd. CH-801-SD bush plane. Because the hangar affords ample work room, I decided to take the K-250 submersible Snoopy out to the hangar as well. This turned out to be a real blessing-in-disguise because out at the hangar Snoopy was safe from the impending doom that befell our property a short while later! Snoopy was torn apart for overhaul in late 2018 (a process which both Alec and Steve have been extremely helpful with) and her parts were all moved out to the hangar over the summer before the fire, so she's all safe but still in need of sandblasting, painting and reassembly. Beyond having the sub project and airplane project running concurrently, I've also been working on a house of my own down the road from my parents' place... the fire was God's way of telling me that it's time to move out of my parents' home and starting living like a so-called "adult" hahaha. Both the rebuild project of mom and dad's house and the restoration of my own house down the road are coming along nicely despite some delays caused by the various virus shutdowns. With any luck we should be moved into our 'new' homes by the late spring and then full attention can be returned to the projects at hand. I try to head out to the hangar when I have a couple of spare hours and get a little something done, mostly with the establishment of a "shop" (crane, work bench, drill press, lathe, etc. but I put shop in quotations because it's pretty makeshift at this point). As to a potential PC-'21, I would love to participate but I am hesitate to offer my services, especially so down in Islamorada until I get a better idea of when we'll be moved into our new homes and have our lives back on track (obviously this takes priority at the moment). We also have several events coming up this year including an airshow and a wedding, but those are partially dependent on how COVID plays out as well. Although I really can't offer any hard and fast assistance this year, my desire to participate in sub events remains strong. If you guys come up with something for this year, please keep me in the loop because I'd like to see if I could make it (almost certainly without Snoopy for this year). I am eager to get back under the water ASAP, but sometimes the best things are worth the wait. Best wishes to whoever might be reading this, hope you are all staying healthy and safe amid this dreadful pandemic. ~ Douglas S.
