Amphibious Screw Drive ATV Project - Part 7 - Hydraulic Tank

[@herenow2895]

Hi there, have you got any plans to do the next stage on this ? I know what it's like to be part way through a project and for it to grind to a halt, for whatever reason. The hardest thing is to get going again sometimes. Come on man, dust it off and start thinking about some experiments with the hydraulics. Like how small a reservoir you can get away with. I like the sound of incorporating an oil cooler or two. I've just binge watched the whole build, so really keen to see the next stage. Hope all is well with you and your family.

[@thomasjr8360]

Are u still working on this? Is it done? Part 7 is the last one i can find

[@69jbr69]

Great work but definitely put a radiator in to save weight and space, no way you need that much fluid. My little skid steer only has 6 gallons in reservoir with half a new tranny sized radiator and it's 40 years old with an air cooled twin and still works great. Slap an atv oil radiator in there with a fan for easy plumbing and you should be able to get away with a couple gallons total. I was gonna build something similar but basically just a little tank with snowblower tracks for ice fishing and use an aluminum oil pan off a car I had as the reservoir I had laying around. Also have a junk electric wood splitter that has a perfect aluminum finned housing on motor to make a nice little reservoir that looked interesting but made plumbing more work. Just a couple ideas, my projects unfortunately usually end up theoretical so fun to watch yours take shape. Keep at it!

[@douglasthompson2740]

Great to see you back at the "Rube Goldberg" bench! I really enjoy watching your thought processes as you fabricate your creations. Take care. Doug

[@Kugos27]

awesome to see another video rednic. A step back always sucks but its better in the long run!

[@bloodredhornet2704]

Where is this project now? Shame there doesn’t seem to be any more videos on this. I love this kind of stuff and you have done great work. I built a hydraulic powered go kart last year and it was a fun project. This one looks cool. And yes you can way undersized your tank if you use a cooler and even smaller if you use an axial piston style pump. I know life and budgets happen, but this thing yerns to be completed! Good luck. And Godspeed.

[@kennethmonson]

An update! Was just thinking about this the other day, glad you're still on it.

[@evanverret3150]

Awesome to see you back

[@Kizmox]

Just add an oil cooler and dont count on tank cooling capacity at all. You will get away with just few gallons of total volume.

[@mazdalorean]

Might not be a bad idea to throw a few baffles on the inside to keep a column of fluid from sloshing around in the area where you will be drawing from. This way if you find you don't need as much capacity , you can fill it part way and save yourself from carrying around unnecessary weight. Nice job as always , and thanks for the update . Looking forward to your progress. Joe

[@REDNIC79]

+mazdalorean yes I plan to do barrels after I place the bugs in the tank. Thanks!

[@REDNIC79]

[@buildexplore3278]

Looking forward to the video! Great project!

[@La_buse_qui_file]

Heyy, nice to see some update ! Congrat ;)

[@JacobGilkerson]

Like others say. Put a cooler on. 5-7gallon tank would be fine. To give you a reference. My asv loader puts out 38 gpm at 3300psi. Its tank is only 16 gallons.

[@BCElginTex]

Wow. I've been following this project from the beginning. That looks like a lot of weight for the engine size, once you add all of the hydraulic equipment and fluid. Can't wait to see how you are going to engineer your way through this. Looking forward to your next post.

[@REDNIC79]

+BC ElginTex yeah your right....i figure since I had plenty of power on the last machine...it should be enough for this one...i hope..hehe

[@theoverlanderutv2747]

Anything new happening with the screw drive atv? I'm looking forward to seeing what you do

[@malakiblunt]

WooHoo ! realy happy to see you back with an update :-) You could always use the screws as tanks for the oil they must hold about 30 galloons ;-) rather like racing bikes that use the frame as an engine oil tank .

[@silentbob267]

It would probably be a plumbing nightmare to maintain hydraulic flow and pressure to a rotating tank like that. Plus with all of that stress on those tanks if you cracked one you would make a heck of a mess.

[@malakiblunt]

i wasn't being entirely serious, and im certain Rednics solution will work and is much simpler which makes it good engineering , , but none the less it would be relatively simple to use the screws as oil tanks , you wouldnt even need a rotating oil coupling as they pick up and return can go through a sutible large fixed center shaft , and as the tanks are always full maintaining oil feed is not a problem either , its true the weight of the screws is higher by filling them with oil, but since you havent increased the AUW of the vehicle the loads ther carrying is the same , though it would increase unsprung weight it also lowers the CG . like i say not serious but fun to think about .

[@silentbob267]

Yeah it might sap power having to spin the liquid as well as the screws though. Spinning the fluid would also add friction and thus heat to the system plus the friction of the screws on the ground would add even more heat to the system. Or maybe the screws would help dissipate the heat to the ground and air. Would probably need an engineer to answer those questions.

[@smokeygasser4037]

Use the pontoons with a hollow axle shaft with a swivel fitting 😉

[@johnassal5838]

Btw, something you may or may not find interesting (or already know) is you can improve it's top speed by having more than one screw thread on each pontoon. It's the same principal as with screw gears only here the Earth takes the place of the gear meshing with the screw. A multiple of parallel threads is equivalent to spinning the screw that multiple faster. A side effect ought to be less torque the engine/motor has to fight as well so less stress on the works too.

[@johnassal5838]

Not sure how to work the plumbing at the axis tbh but you could use the pontoons internal volume for most if not all of it.

[@mwhite5330]

Man, I was just looking for the last video a few wks ago and wondering if my notifications were broke... lol Glad to see progress !!! Keep it up !!! I share your channel w every gear head I meet👍

[@REDNIC79]

+matthew white thanks man!

[@silentbob267]

It may just be hard to see on camera but those welds on the inside look a bit large for the thickness of material you are using. A good rule of thumb on material that thin is to tie into each plate about the same thickness of the material you are using. A hair extra won't hurt but much beyond that will just add unnecessary weight and put more heat stress into the material than necessary. Since that is part of the frame it would help add strength to weld it solid inside and out. That would also give you an added layer of protection against leaks and it should draw the plates in and out evenly enough to help prevent warping. I would also recommend stitch welding a few inches at a time and moving around a lot to also help minimize warping. Other than that it looks like it's doing great! Keep up the good work.

[@REDNIC79]

+Craig Arnold don't watch so closely! Hehe..joking. thanks for the input, I agree

[@Mekhanic1]

All you need is enough so it doesn't run the pump dry. I am an mech. engineer and designed systems in school. I would use a 1.5 gallon (extra) of fluid in a 2 gallon tank for expansion.

[@bnblpt1]

Use a KID LTV, it has dual HSDs and uses a W-4. Simple 2 cable and large drive gears.

[@onetrickypig]

Where have you been my friend?

[@SwampDonkey530]

The old adage is true....If you build it...people will criticize it!!! LOL

[@ccga3359]

Off topic but I'd like to see the tins from the old garden tractor used on this build as the grill is reminiscent of the old Fordson Snow Tractor. It might also give room for the fuel tank and sundries.

[@JSMachineWorks]

Ayyyyyy! Screw drive atv!

[@mikeyb4642]

I'm glad you're still alive, haha.

[@davepedu5896]

Hmm, I can't help but think your fluid mass calculations are off. Just look at the stack of 3 (but actually, you'd need 6) buckets next to the ATV frame. Does that volume ratio make logical sense? I don't think so.

[@davepedu5896]

I just read down and various other commenters seem to agree. Think of it this way - you'll be driving this thing in the water and mud and you've build a waterproof storage area!

[@tylermarkowsky7917]

Best thing is the video. Second best thing is the peanut gallery.

[@SpenserRoger]

Don't be rediculous. 15 x 7.2 pounds per gallon is 108 pounds! Run the minimum amount of hydraulic fluid, like 5 gallons, with one or two oil coolers+fan. Run a well designed system accumulator or surge tank or anti foaming device if that's a problem. And ya great idea to make the tank part of frame. I'd keep the weight low and unsprung if possible. I don't want to see this new rotary suck balls like the last one! I've been following way too long for that, lol. make us Canadians proud, eh?

[@REDNIC79]

+SpenserRoger I need each screw motor to put out 150 lbs of torque....flowing at 12gpm it will create lots of heat. Coolers are heavy too. So is any other device I add on. The tank likely holds 10 gallons in its current state, I would rather be able to remove some fluid than not have enough room in the design to add more. The machine is going to be heavy as hell with hydraulic drive. There is no way around it.

[@SpenserRoger]

REDNIC79 Do the coolers need to be high pressure? Cause if not standard transmission coolers from the junkyard are aluminum and like 10 pounds at most. 12v fans are in the grams. If you're not running the 3-5x reservoir size you're gonna get heat problems regardless. And ya make the damn tanks unsprung bro. We all wana see you hit some step downs and do hill climbs with this beast!

[@SpenserRoger]

Are you using aluminum screws or steel? aluminum screws with bolted on steel would be bomb bro. ITS GOING DOWN BRO... DOWN AND AROUND AND AROUND AND AROUND... WOOOOOO!___ ps: man do whatever u want, I trust your judgement, and will be excited and support your project the whole way!

[@REDNIC79]

+SpenserRoger I think the cooler ate usually rated for a few hundred psi...mainly for hydraulic rams causing pressure in the return line...i could possibly get away with a car trans cooler. Problem would be it would need to handle the flow..ie a 1inch return line flowing 12gpm

[@REDNIC79]

+SpenserRoger aluminum screws would be ideal

[@ratherbflyin3301]

50 gallons!?! *checks helicopter specs (ec130 t2) *500psi at 3.2 gal/min (1.6*2 dual hyd pump) *0.5 gal tank total (abt 15% of flow rate) *No radiator described in flight manual *Hydraulics routed through transmission for preheating *Uses hydraulics for entire flight. I’m no expert, but maybe you could get away with less than the 15 gal you’re suggesting? That flow rate is unreal though!

[@REDNIC79]

+Rather B Flyin a helicopter hydraulics are totally different. Way less flow and pressure. 12gpm is normal for a large agricultural application.

[@ratherbflyin3301]

REDNIC79 holy cow! Yeah I know nothing about that, then.

[@likeabossss463]

what no drain plug on the tank you might want to incorporate that into the design so if you need to change the fluid it is a lot easier

[@CumminsDriver]

I dont think there is any way possible you should need that much fluid. A 773 Bobcat skid steer, which is hydraulic drive, with 4 hydraulic cylinders as well as hydraulics to run an attachment only has an 8.5 gallon capacity. Yes it does have a cooler, but its made to work at full capacity for hours and hours on end. Im thinking you shouldn't need a hydro system much if any bigger than what my exmark mower has, which i believe is only about 3 quarts. Dont take this as being hard on you because your metal work is great and enjoy watching, I just dont think you're going to need that kind of capacity.

[@REDNIC79]

+CumminsDriver635 I would be very happy if you are right. Thanks for the hope!

[@vizionthing]

Great to see another upload, but hey really think this is the wrong solution, the weight of the oil along with the bulk of its storage ...... just get a cooler fitted, thinking outside of the box has its place, but have you ever seen a hydraulic system that comes close to what you are doing here in a commercial (or for that matter any other) system? What ever you choose, good luck we look forward to seeing the end results

[@TheMetalButcher]

Our backhoe has a 20gpm pump, and I don't even think it holds more than 10 gal. It does have an oil cooler though.

[@REDNIC79]

+The Metal Butcher I think the cooler is a big factor....i mean what if I decide to circumnavigate the globe with it? Can't have overheating issues. Hah

[@JSMachineWorks]

I Know you just built a fishing sled but are you still working on this thing?

[@REDNIC79]

just had a baby :)

[@JSMachineWorks]

REDNIC79 oh! Congratulations :)

[@oldreliable303]

you need the tank for cooling more than anthing else, why not use a oil cooler or trans cooler? and all the quad part you didin use if you can box them and ship them to me ill pay you for it, i has a plan for a little 4x4 buggy im building

[@metheone4]

Hey Nick,you re back! Long time since last video...Looks you have made some good progress , evaluating your hydraulic system/vehicle. The solution for the reservoir looks very profund-well done!What about some rods from side to side inside the tank to make it stiffer and stronger?Looking forward for the next vlog! :) Happy halloween!!! greetings from Austria,Knud

[@REDNIC79]

+NoName I plan on doing some baffles in there after I figure out where the lines are going to hook up. Good to hear from you too, I look forward to your opinion as things progress. Cheers!

[@ДенисШестаков-т9т]

Когда до делаете новый шнекоход?

[@davespalla9684]

Each of the screw drives is a tank, maybe you could utilize them somehow?

[@REDNIC79]

+Dave Spalla I think that is a really neat idea, possibly even a portion of them. Good out of the box thinking!

[@MrGordy61]

Sorry to jump on the "you don't need that much oil" bandwagon. But do some research on colt/Case/Ingersoll garden tractors. These handle a hydraulic tiller in heavy clay based soil just fine with about a gallon of oil in the tank after the rest of the system is filled. Gordy
