Could use the spare output shaft to drive a large water pump. Supplying a water cannon to defend against pirates or extinguish fires. Plus it would be cool to watch you build your own water cannon
Or a high volume pump for emergency to save this boat or others sinking in an emergency.
Now I want a water cannon.
Sourcing one from an old fire-engine is probably the way to go. Hopefully nothing bursts and bilge pumps can keep up.
Hey, it can work also as a super-bilgepump.
But you need to install a fire hydrant on the deck 😂
@@jaba512 A sturdy old fire engine pump would be ideal. Would be cool if the water cannon was made to look like dragon as well
@@KillerNetDog Yeah that would be very useful. Would have lots of applications, could be used to run a suction dredge as well. Sail up to Alaska and go gold diving
I'm another old salt, fished commercially for 45 years on a 1926 wooden 42 ft Troller for salmon and crab here in California. I installed a new Detroit 4:71 High Block diesel with a Twin Disc 506 transmission in 1987 and its still going. I really appreciate your video's and especially this one when you explained your journey on building your boat and the parts your using, makes sense to me now. For me I never had a breakdown with my setup, but I was in a different situation, I needed something that was proven and dependable. If I didn't catch fish I had no income for me and my wife (by the way she fished with me the last 35 years, best deck hand on the west coast). Keep up the great videos and with this one I can now just setback and enjoy your build without saying to myself why didn't he to this or that. Just enjoy people!
As someone who has ran a junkyard, holding on to old stuff is a waste of space and money. You buy new stuff that has a lot of them on the road. When you run out of space, the oldest stuff gets sold or scrapped. And even if you dont run out of space, the price of scrap spikes every few years. Scrapping the old stuff in bulk at those times pays for new stuff for years. The old stuff is not in junkyards, its in the yards of junk collectors. And most of the good stuff is still there because they dont want to sell it.
^THIS. I'm a "millenial with skill and ability" its the boomer hoarder generation keeping me from getting anything worth a damn. I've resorted to the 90's cars of my childhood because I can't afford a classic muscle car. Even one that needs completely rebuilt. A fastback mustang goes for 15k and the only salvagable item is the roof and VIN tag. meanwhile I can buy 70 80 90's vettes, and 80-2000's mustangs that run and drive good with no rust for the price of a late 60's early 70s muscle car thats in pieces.
@@garrittpwl Those "boomer horders" are the only reason any of those old muscle cars still exist. They were worth more as scrap than cars by the late 80s. Every car still around from back then is because some old man refused to sell it. They were heavy, bad on gas and dangerous. I remember looking at a mint 68 charger in 1995 in a car lot for $800. I bought a really nice 78 firebird for $500 in 1999. I needed something cheap because I had wrecked my 84 firebird. These were rare already but the people buying them were kids to use as beater cars. They had no value. By 07, most anything from the 70s was gone an I was buying thousands of 80s and 90s cars for $100 a piece. By 09, the only thing left was running cars and cars no one would sell. Probaby worse in the rust belt. That car at that dealer was the last charger I ever saw someone selling. Some kid bought it an wrecked it. I wanted it but I would have wrecked it too. Those old mustangs are still around though. The fastbacks were rare to begen with. But you can find fixable survivors all over the south for around $4k. Cousins kid just resored a 68 for his highschool car. His dad just bought a nice 68 chevy truck for $500. Neaghbors wife finally told him she wanted it out of the yard. The old stuff is around, it just takes patents. He had been trying to by that truck for 20 years.
ooooo fk yeah 46mins of pure joy, really like these long episodes, much better than any movies nowdays!
Gulag Archipelago! Nice light book tape to listen to while floating peacefully on a sailboat 😂
"Cash for Clunkers" ruined the junkyards. The junkyards scrapped all the old stuff to make room for all the clunker trade-ins. What most people don't realize was there was an 18 month time limit until the clunkers HAD to be shredded (under severe penalty). This cleared all of the junkyards, leaving them empty. The yards that didn't participate were now filled with unobtanium and the prices went through the roof.
thanks obama
All part of the plan, they don't want us repairing old. 🤷♂️
the part I never understood is how they could charge nearly new prices for a part that was clearly well used. Had a friend back in the 90's with a car that had the ignition control module built into the distributor that failed. tested everything and narrowed it to the module itself. checked with the local parts store: $350 for a solid state electronics part smaller than a credit card. Got the idea of finding one in a junkyard and see if we could just replace the entire distributor. They wanted $275 for it, and we had to go take it out ourselves. He only paid $1000 for the car total to begin with.
Love it when you release these long videos solving problems without just throwing cash at it which is what so many other youtube channels do
You didn't need to use the other yoke for a PTO there's a square "inspection plate' on the NP 205's for a PTO, I have it set up that way on my 4 door 4 wd Dodge W 200 running my 12,000 lb. winch off a duece and a half. I guess you have 2 PTO's now. Lol, edited as I watched further on, I have 2 NP205's laying in my yard, divorced. Wish I knew you needed one or 2 for extra parts...
This will be great when the seas are lumpy. Drop it into 4-Low and power up and down the waves. And, you can send a new guy out on deck to lock the hubs. 🌊🔒
4-Low definitely good for climbing those big waves
That's assuming they get around to installing 4 screw drive. For now it's just 2 low.
With the load normally placed on that tcase in a 4wd truck, that split in the case would worry me. For your use it'll probably never be an issue unless your prop binds and that happens to be the weakest link. I'd put it on my todo list down at the bottom to have a spare case ready for that day it comes back out for something or in case it breaks.
When someone knows what they're talking about, it shows in the nuance with which they speak. You guys are really very very good. Thanks for teaching us. ❤
I earn my living doing impossible things like this. Big companies don't like doing one-offs, middling companies won't take the risk, but I'll give it a go!
Too stupid to know it can't be done, but smart enough to make it work!
And why don't you have your own YT channel? Guys like you make YT interesting and fun:-) Just saying.
@@Dutch58 I'd love to, but if you've ever tried to film yourself (and making it worth watching) you'd know just how much extra time it takes, and that's time that doesn't put bread on my table. not to mention that most of my customers would throw a hissy-fit if I put their deathtrap-contraptions on the internet!
@@theafro Lol "Deathtrap contraptions". Now you are making us even more curious. No, seriously, I'm trying to understand it, but weak arguments remain :-) Just kidding.
@@Dutch58 I do a lot of work on reed-cutting machinery, think combine-harvester but angrier! they're mostly whirling bits of sharp metal connected together with big flapping belts! keep an eye out, one day I'll post something!
We used transfer cases on big winch trucks that did basically the same thing y’all did with this. We used an air valve to disconnect the engine from the drive axles and apply it to the 80 ton, 120 ton and 200 ton winches and we selected those with air valves as well. We could also engage the winches at the same time as the drive axles but it wasn’t a feature that was used very often. Always worked very good and we actually liked it better than hydraulic winches in most applications because you could spin the winches either really slow or really fast using the transmission gears and throttle pedal.
👍👏👏👏 BTW, NP205 mods (twin stick) have been used in off-road rigs for many years. The mod enables only the front tires to turn and the rear either to freewheel of lock-up. It's called DIGGING. But, you know that now. 😉🙂
PTO ideas, Allison powered drinks blender( worlds most powerful, rum runners by the gallon) or a purpose built coconut cracker, for when you get farther South.
Really interesting video. You're right, there's no junk yards like that left in Florida anymore. There were thirty-odd years ago when I was a kid, but the combination of rocketing population and the accompanying rise in land prices, coupled with increased over-regulation from various state entities, they all scrapped what they were holding and sold out to property developers. Same thing happened to most of the orange groves after a particularly bad bout of citrus canker, all gone.
Teams of people including experts, loads of work , several months & a fair bit of money/expenses... And what do you know! A complex marine gearbox system giving desirable reduction , which at the moment seems to be a success! You proved us all wrong !
“…if it does it’ll be an exciting day!” Lol. Let’s hope you never have to experience that excitement!
Thank you guys so much for the in-depth discussion about what and why!!!!
It sounds like you didn’t need a transmission at all. Have your clutch going directly into your transfer case and rely on your transfer case to provide whatever gear reduction you need. KISS
Fantastic ,two engineers ,nailed it .
Could watch all day
It sounds like you guys could needed to speak with someone who works with this stuff a lot, and there are a few of these guys who have their own youtube channels. The channel that I would recommend is Fab Rats out of Utah. Fairly popular youtube shop that builds off road rigs for exploring the desert, and I've seen them convert several transfer cases, rebuilds, and anything else you might need to know. Also, if they don't know the answer, they could surely find the answer for you real fast.
People complaining about vibrations not going away, about fuel efficiency and about wear are not knowing a lot about engines. This is not industrial engine at all, it is vibration vise balanced for middle of acceptable rpms. Being near idle under load is fine only for seconds, as it is wearing a lot with low piston speed and high combustion pressures. Even if working like this saves fuel (witch it probably doesn't) it is not worth the wear.
Some engines are not even squirting oil to pistons down low on rpms, and would simply die at 100% load down low, if that would not end in hours. Not the case obviously, but in cars it makes engine die while "eco"driven past limit. A lot of typhical automotive engines develops a piston slap from this miss usage in like 60k miles
I've owned over 300 second-hand cars and trucks in my 75 years and the feeling I always got from keeping them on the road, figuring out the problems and fixing them, is a feeling of real ownership. I purchased my first new vehicle 6 years ago and that deep feeling of "this is really mine" was missing. But, I get the old good feeling when I think about the more than 100 repairs and renovations I've done to our 31 year old RV and the complete rebuild I'm in the middle of on our 30 year old boat and trailer. When you fix or replace or improve everything on your vehicles, etc., you really "know" them. The feeling is real personal. You don't have to know anything to buy a new car but to make an old car new is life-changing. Obviously I'm referencing everything you guys are doing on SV Seeker.
Loved the video, Thanks! Can’t wait to see, Seeker doing some “OFF ROADING”! 🙂
I love this Exploratory engineering, you give us budget hobbyist hope.
Budget hobbyist Rule! The others shop and copy. : )
Hi, just an idea for you . I'd use cv joints ,instead of ujs more contact and a lot more forgiving in alinement
You 2 are crazy....... I was born and raised on a farm. We have done some crazy stuff on the fly..... But this was over the top..... Great job.....
Just realised I’m wearing exact same shirt you have on Doug…Wrangler snap button, same colour. Stiff as a board for 6 months. Favourite shirt now. Great job on the transfer case. Love the channel
Loved this video! Finding the time to slowly get caught back up on your adventures.
I was wondering if you could film an update video on the ROV, or speak on it in a future video. It was what brought me to your channel 5 years ago when I was looking to build my own submersible, and was a huge inspiration for me to pursue engineering to try and make stuff even half as cool as that! Thanks and love what youre doing
This comment is about "old school".😂😂 When I was a child 40 years ago. My father took me to a local junkyard. The old man who was in charge was literally a book of knowledge. My uncle was working on his dragster. It was a late model Dodge Duster. His last run at the local drag strip he twisted the axles and snapped them for the second time. That old man said he had another set but if we didn't want to come back again we need a set out of a different car. He told us to go out to a certain old station wagon. Pull the axles and take them to a local machine shop. There they turned down the bearing surface to fit the axle bearings. After shortening both axles slightly they fit right into the axle of the dragster. He never ever broke the axle shafts again. I miss the old school generation. 😊😊 On a different note. NASA once admitted that even though they have the original plans for the Apollo mission rocket engines. They have never been able to build new ones that worked properly. Turns out the old engineers that originally built them took the secret modifications to their graves.😢😢
Fantastic engineering! Think you suffered from propeller cavitation , reducing the rpm range solved the problem, tunnel propellers can do really bad mechanical noise when cavitating, cp propellers if run on a const rpm range will cavitste at low pitch - you learn by testing, ships have a preprogrammed combinator curve working three signals, pitch/shaftrpm/engineload.
The trick is matching up the drive train/prop to the most efficient rpm for the engine and it seems your a lot closer now and with a spare power output to boot. Can't wait to see it in action. Make sure to monitor the heat in that transfer case, some of them can get kinda hot under sustained use. A cummins powered scuba compressor sounds awesome too.
And yeah, all the older Iron got scrapped back in the big China scrap boom when scrap prices were through the roof.
I've built some dirt track race cars and some hot rods. I'm a UTI graduate also. I was always told not to aline 2 shaft exactly when using u-joints. You should have them offset . This would help with vibration and noise.. It puts a side load on the 2 joints . If they are exactly lined up , there is no support for the joint, and are basically flopping around.
You're advocating that they should be slightly out of phase? If so, I would love to see the white paper, or testing behind that.
The real rock bouncers love the doubler transfercase. 😊
Another ambitious project--well done guys! (And I appreciated the walkthrough of manual transmissions)
205 transfer case can also mount a power take off for things like hydraulic pump, generator or air compressor.
Are there any concerns about lubrication on the top pinion having the transfer case vertical like that? They are designed to have a sort of oil bath when it's horizontal right?
Next video is a test run where we check temps and oil transfer.
I don’t think any of that was stainless but heat and beat will also get the results you want. :)
If the u-joints fail early, may look at getting a "double cardan" joint from front driveshaft of the 4x4 Ford Super Duty truck starting in 1999.
Pretty awesome. The other big advantage of using this transfer case is parts availability. All of the seals, bearings and gears are locatable. Any reason NOT to put a rubber foot under the transfer case to help with vibration dampening?
May I suggest using the second output having the option of putting a generator on it. The 5.9 will be fairly efficient under 2k rpm even for generator duty.
You can use some Lucas oil to ensure the gear oil gets to the top output shaft gear with the low rpm
You’ve got a very intelligent young man taking the lead in this project I’m still not convinced about the propeller I don’t understand why a fixed propeller would not have been a better proposition for vibration problems cheers great video
He wanted the availability to feather the prop for sailing, or really fine pitch for pulling.
I don't mind the longer video. I was so interested in all that you shared. I love the knowledge, my learning and your sharing.
I have a small three speed browny I would give you guys that would fit in there perfectly for you I would've thought about it I saw your previous video asking for a transfer case. I enjoy your videos and have a wonderful day
the twin stick thing is very useful for guys like me that are off roaders. there are lots of fun times when you need different rates or front wheel drive only. its pretty nifty. i've been trying to source one here in texas for some time, but like you said there is just not much for old stuff. its getting to be a slimmer and slimmer market for guys like me in the older categories. if i can track down everything it will be a small miracle.
I wanted a pure hydraulic drive for the Seeker... Pump and motor, hoses and valves.
No shafts, yokes, gears, etc.
I had thought about saying something about a bolt on overdrive but I didn't thank it would work and I though the transfer case was a better idea.
Glad it worked out.
Couldn't agree more, the fun is in the head scratching trying to figure out how to make it work and the satisfaction when it does...could it need some tweeking as you use it?... sure but that too is fun, if you wanted to buy parts rather than build you could have just bought a boat 15 years ago and been done with it... the challenge is in the building, I have been converting a 1971 MCI bus to a motorhome for the last 8 years.... stretched 5 feet, 3 slideouts, 12" raised roof, I built it all ...with my Dad's help. I could have just gone and bought a motorhome 8 years ago and been done too but again, no fun, if you are curious I have it all documented on my channel as well, just a thought but how about mounting a hydraulic pump on that spare shaft on the transfer case and running your dive pump , compressor and anything else you wanted hydraulicly. Easier to run lines than a driveshaft... could run a generator to charge your batteries as well, just run to a manifold and use electric valves to switch whatever you want on or off...just a thought... anyway , thanks for the ride, it's always fun to watch you guys do your thing.... From Southwest Canada.... James
Ooo, you just got yourself a new subscriber.
@@kevlarandchrome 😂😂 Thanks, not really why I mentioned it but always good to have new viewers... I've been following these guys for years... they do amazing work... we need more people with this mindset
@@JamesEDennison Well, yours looked like a cool project, and I really enjoy buses and boats. I'd love to do one or the other some day in the not too distant future, so it's always great to see what other people are doing, especially when they've got good and extensive documentation like you seem to.
Your ability to find what works, and to find the right people for the right job is amazing. You videos are a great encouragement and help complete some task, I would have normally hired out.
Don't want that on your normal vehicle? FRONT DIGS!!! I need a safe place now.😂
Doug, you all are doing great things! Love the work, all the energy and most of all great teamwork. Not afraid of making a mistake can cause great success!
Cool setup. My only suggestion would be to keep spare universal joints on board (as well as other critical parts). The sea is unforgiving, and "Murphy" of Murphys law lives behind every wave.
Thank you for your videos. I have no intention on building a boat, But you inspire me to keep building and improving my property.
6 years ago, I bought a 5 1/2 acre piece a land with an abandoned house on it, Been working on it every weekend.... 4 years ago, my wife and I got the abandoned house removed and got 1 acre of it useable and we have been making steady progress every weekend that we have time to work on in. My back 4 acres is extremely hilly land that most people probably wouldn't use. I have since gotten a switchback path hacked through dense forest, packed rock, and red clay.
We have built 3 chicken coops, raised 3 generations of chickens, and we are continuing to make gardens all throughout the south west side of our hillside.
My next project is to build a workshop into the side of my hill, I have a small shed but it is inadequate... It is very hot in the summers where I live so partially imbedding it into the hill and with lots of tree cover will help keep it cool so I can work more effectively.
You inspire me every time you say "Just turn it off the video and get out into your shop and do something", I guess I better build a shop 😅
Thanks for sharing your story. It inspires me.
Should have just got a used marine transmission. To many points of failure with this bodged up contraption. If the bus trans doesn’t fail, the transfer case will.
May I remind you there are hundreds of thousands of Allison transmissions and transfer cases in use all over the world. But if you want to do the “normal” thing you do that.
Did you watch the video? That's not the point of this boat/project. They want to build it, not buy it. Plenty of people in youtube that slap part together.
@@SVSeeker EXACTLY!
I applaud you for your ingenuity and ability to make stuff work. However, as I have been in the Marine trade for fifty years, I also realize that things are done on boats certain ways for safety and reliability, there are many Coast Gurd regulations regarding systems, and they are there for a reason. Things like air cooled engines below deck. Wait until you are in the tropics and try to run that generator thing of yours. I hope you never face catastrophic failure under bad weather at sea.
Its on a boat, it is a marine transmission.
I think this is in the spirit of using school bus parts to start with. Seems like a cool idea to me. Love the explanations behind all the comment suggestions. Glad it's working!
I had a friend who was the first person to use an automatic transmission in a Pro Stock race car. He put in something called a "positive shift controller". It caused the transmission to stay in whatever gear he selected, no automatic shifting. A big advantage because it allowed him to launch in second gear when the track conditions were right.
You could have this done, so that the ONLY gear options were 1st, neutral, or reverse. Yes, it would require finding some shop that knows how to do it, and it would require pulling the transmission out and taking it somewhere to have the work done. BUT, it is an option should it ever become necessary.
Run a hydraulic pump off that second output from the transfercase, then you can power the air compressor with a hydraulic pump, plus your crane and alot of other equipment.
Always amazed me how that is the reply from everyone in the marine industry. But you also forgot it just won't last, corrosion will destroy it. Always wondered why torque is never figured into prop sizes. 👍👍👍👍👍🍻🍻
im pretty sure hansen auto parts in omaha ne would have the transfer case you were looking for . they have huge huge inventory on older drive lines
Almost as entertaining as an old A-Team episode😂
You guys should run a generator off of the extra yolk on that xfer case for a backup power source.
A word of caution about pilot bearings, not all motor crankshafts are drilled for them. I've seen a few motor swaps, over the years turn into a nightmare because the crank was never drilled for a pilot bearing. I even swapped out a 318 Chrysler for a 360 in a I/O boat and the Volvo Penta bellhousing wouldn't bolt up to it because the pilot was not drilled. Lucky enough it was still in the garage before it was about to be rebuilt. Had me flipped out that I bought a motor that my bellhousing wouldn't bolt to until we figured it out.
You probably got rid of some oscillation by adding that transfer case, smoother ride and better point of failure as you mentioned.
In my case when I recommended the gear vendors to you was because I use it on my race car ! My car competes as both a quarter mile drag racing car and streetcar I can leave the gear vendors on for driving down the highway and off for the quarter mile❤
PS the events that I spoke of are called drive and drags they are multi-day events that involve three or more race tracks and require you to drive the car from track to track
I like to watch while working and pause between fares
I could be wrong but I think you have an Alison 1000 and they do make married cases for the 1000. They are in Chevy hd trucks.
Nice technical discussion and wall through at the end!
Put an electric drive/generator on that second output/input. Then you've got all sorts of options
I bought a us gear (gear vendor) under drive unit in 1998, still have it in a 7.3 powered f250.... At that time you had the option for either o.d or underdrive gear sets if i remember correctly they were rated a 35k weight gcw rating. That being said I think you are still better off with the transfer case....
Thanks for sharing the details
i know a spot in jacksonville that has 205s and 203s. obviously the divorced ones are harder to find but they get em from time to time. if you need a spare maybe check them out
I think the same way. I knew exactly what you were talking about as soon as you mentioned the divorced transfer case, and every bit has made perfect sense to me since. Looking forward to seeing the full shakedown. Love the videos, keep up the good work, and thanks.
Anyone that knows diesels knows they run the best in there sweet spot a for a 5.9 Cummins that's between 1500 to 2000 rpm
isn't that true of most engines?? seems like every car i've ever owned, seemed to "like" running at the speed required for driving down the road at about 55-60 mph.
From my old Galaxy, thru my Thunderbird, to my Impala, and even my Civic and current Escape, they all seem to be happy running at road cruising speed. Always figured that was the speeds they were designed to operate.
Wow! Andy is a gem! Such clear explanations!! I love this project. Thanks
Your verselbstständigt is a Never Endung Story😸 i Miss the wharp gondels. Greatings vom germany
Some interesting ideas there Doug, hopefully they work out.
Innovative and determined. Love you guys attitude. Love the fabrication to get what you want. Great stuff.
I really like the in-depth discussion of this transfer case and what the process was for deciding to put it in. I'm working on a vaguely-related project that involves an 8000:1 gearbox that was driven with two 7.5HP DC motors. We can't use those old motors, and don't have the power budget to put in new 7.5HP motors. Sooooo, we're using a 10:1 worm-gear right-angle drive and a much much smaller motor. It won't achieve the previous speeds, but we don't need high speeds. We need something that fits our "practicality envelope" and "cost envelope", and that's exactly what you guys are doing. Carry on. You're doing great!
Thank you for sharing once again, I love how much everyone is helping each other, awesome work
Thanks
Mick from Queensland Australia
I don’t know anything about transmissions and gearing, but that discussion was very interesting, thanks for sharing that.
Take care with the air compressor
It needs a constant rpm and a minimum rpm
The oil is moved around by splash while the crankshaft is rotating if it's to slow you won't get the oil lubricanting the pistons
That is expensive to replace
If you can have the stable rpm same the the electric motor with the air compressor then you are good to go 😊
Dallas ,what a great gent .humanity is alive
That took a lot of effort but it looks to me like it will do what you need.
That paper shim probably caused ol' Dad to roll over in his grave. He was a tool & die engineer. But you have to do what you have to do. Especially if your machine shop is in the bottom of a boat.
That's the perfect place for CV joints, pity you did not use that...
Oh jeez - I missed the last few episodes. Anyway, for anyone else looking for a divorced transfer case, they're usually limited to heavy-duty applications, just because they're more expensive and a more complicated installation. I THINK some of the heavy Fords and Dodges came with them, or you can just look for any 3/4 or 1 ton IHC. The '70+ models will have a divorced 205, the earlier ones are also divorced, but I don't know what model they had.
I never questioned if it would work, I'm more concerned about reliability long term. i think it's definitely possible, might need some modifications long term. Doug if you need any heavy parts machined, let me know, I've been looking for an excuse to make TH-cam vids, and I've got 5 cnc machines in my shop.
at least the tcase gives you a pto,big awesome there
Wow Andy, I could listen to you all day, you’re expertise, curiosity and know how is commendable, outstanding!
Very very interesting. Great watch.
Andy is freaking awesome!
Yes he is.
Just in case you didn't know, parallels aren't intended to be flat in the direction you were measuring. They might be close in some cases, but unless you managed to find a set that was flat ground in that direction after heat treat, they aren't flat.
I never commented on that other video about the prop shaft banging, (or did I?) anyway. I suspect that your prop and shaft are not, (yes you read that correct, 'not') out of balance. but that at the RPM you were spinning it, you hit the natural resonance of the whole set up. what is also known as the the 'critical rpm' usually a spot you don't want to sit, you go either below or above.
think tuning fork.
Do the U joints need to be out of phase, or is that just for vehicle applications?
Should have been. Will produce resonance this way
You dont know how happy I was to see someone else weld in crocs also haha!
Could the pto also be used as a means of adding auxiliary propulsion? I.e. small electric /diesel engine could connect to the front wheel output and then run the main shaft for auxiliary propsion.
I learned quite a bit from this here channel.
Not interested in this part? Skip ahead to 47:00. Well played Doug!
Like the scuba compressor being able to use a stronger, more durable motor than stock version. I'm wondering about the driveshaft and relative speeds for tank compressor though... the compressor has a range IT needs to operate in as well, and a driveshaft limits your location options a bit too... what if you took an idea from old drill presses or bridgeport mills and used a stepped pulley system that can be varied by switching belt from various pulleys in pairs to speed control ? Should be easier and more compact to mount as well, maybe scavenge drive from an old drill press too ?
I can't wait to see how she runs under load with the new reduction / gear ratio.
