It has almost twice the pushing power then a normal double acting piston. , but it's allot longer. Can be handy in some situations where you need lots of power and don't have the space for a bigger cylinder.

There is so much more wrong with it. Did you saw at 10:30 how he had to bend the piston rod to assemble it. It will start leaking really soon. Video is looking nice and people who don't understand machining are liking it. But this is not the right way to make hydraulic piston. Most of it is wrong.

[@Sensaatioko86]

isnt the UN-seal leak to she otherside, cause it can handle preasure only from direction of the V-grove. What for you put that dustseal in there at the middle?

[@anomamos9095]

I’m guestemating but the total surface area increased by doubling up the piston that way was only about one third more not the double you’d expect. This would be more of a benefit in retract than push as it is truely double in that direction. Considering all the extra piping it’s doesn’t seem like much of an improvement in size reduction over using a tube twice the diameter.

[@tareksma1]

I think if he uses the same hidraulic pump, it doesn't increase the power.

[@anomamos9095]

@@tareksma1 . The pump size only really matters if it is too weak for the task.

[@Crewsy]

Well. Clearly if you do the math then 2x diameter is MUCH more than 2x the volume so in a Captain Obvious way you’re correct. 🤦‍♂️

[@anomamos9095]

@@Crewsy . It’s not so obvious. The force is exerted on the surface area of the piston, the larger the area the greater the force, however on the second serial piston the surface area is diminished by the piston rod , you would actually get more force out of two parallel pistons than out of the serial setup. There is something that I almost completely forget about how to calculate the force on the second piston however. I kind of remember something about force being slightly greater than the total surface area of the piston with the rod taking up the middle of it. It is less than piston with the full surface area available but more than only the available surface area would suggest.

[@Crewsy]

@@anomamos9095 You’re overthinking it. It’s obvious that a 6” circle has a much greater surface area than two 3” circles so doubling a cylinders diameter will way more than double its pressure. You specifically mention “using a tube twice the diameter.”

[@industrial_design23]

Good job, but just one thing the chamber of the piston will not be ideal because the inner surface is not smoothly so it will damage the seals in small time

[@darylcompton3433]

I thought the same thing, but we can only assume that a man that can build hydraulic cylinders from scratch knows that and probably polished them off camera.

[@industrial_design23]

@@darylcompton3433 yes I agree , really it's great job

[@darrellbedford4857]

My feelings as well about not polishing the cylinder bore. Otherwise a very interesting build. Like many have asked what is it for.

[@Crewsy]

@@darylcompton3433 You know what happens when you ASSume. Another comment mentions that the “pipe” material he used is actually material made for hydraulics so it’s already the right surface inside. I ASSume that’s correct. 🤷🏻‍♂️ I certainly can’t dispute it.

Just for testing and not to make a mess with hydraulic oil.

[@essentialjudge2279]

I find a hollow one is very useful

[@GHuggins]

Do you actually gain more with this? Looks like it would be more economical to have a larger diameter cylinder than to have a cylinder twice as long with half the stroke unless you just gain exponentially with it? Just trying to visualize where this would be best beneficial is all. I could see some machinery benefits with diameter space savings, but again losing a lot with length.

Make a double extending hydraulic cylinder next

[@temptorsent]

If the piston areas are balanced, this design can allow for a no-reservoir push-pull arrangement driven by a reversing gear pump or even hand pump with a directional valve.

[@carni5064]

The volune of the two halves will not be the same due to the volume of the piston rod.

[@temptorsent]

@@carni5064 - Yes, it would require the working area (accounting for the rod) of the pistons be calculated and matched.

[@carni5064]

@@temptorsent i do not think it is possible to be reservoir free. In pull mode both cylinders contain a volume of oil and a piston rod. However in push mode only one cylinder contains a piston rod and thus a different amount of oil.

[@nathanrichart7226]

Just wondered or am I wrong?

[@nathanrichart7226]

Always enjoy your videos thumbs up from me

[@stachsco]

Like always excellent craftsmanship, but idea don't have too much sens, at least for me : you add double the length, instead couple mm of piston radius, if shaft seal start leak you lose pressure in bouth cylinders any way and you triple connections (points of potential leakes) and at last, because in secound cylinder you have shaft, power gain in extend cykle is negligible ?

[@FOXCRF450RIDER]

You should try a larger cup on your welding torch. That looks to be a 6 or 7 and I would use a 10 - 12 size cup. Also do not pull the torch away until the gas has stopped because your weld is oxidizing. Might need to adjust your post flow longer depending on amperage.

[@ninefingerdeathgrip]

But why? Not much extra power available with that piston to shaft ratio.

[@Adversary198]

@@jocelynbutty thank you.wouldn' it be just as easy and cost effective to use a slightly larger ram?t

[@lofman]

@@jocelynbutty not double, you need to retract the area of the rod.

[@lofman]

@@philleeson7835 I think that was the point, maybe you need a really thin cylinder for some reason, this is one solution for that. Not sure he has a practical scenario, more like a proof of concept. 🙂

[@thorloki5449]

@Jocelyn Butty but it's actually only double the surface area in the retracting/pulling direction and like 1.5x in the other(ruffly without knowing piston and rod sizes). The second piston has the rod on both ends, giving it less total working surface area.

[@TheTwistedStone]

Will it be more powerful because it has double pistons and if so how ?

[@NaturalBBler]

It is like having two pistons.

[@felixe.8402]

The hydraulic force is the product of pressure x area. In this cylinder are two separat volumes so the area from the piston is nearly doubled (second area is reduced by the piston rod)

[@EVLS10]

It's essentially pointless.

[@carni5064]

It will be almost twice as powerful than a single piston with the same diameter cylinder and piston rod diameter. It will also require twice as much flow, so operate at half the speed as a single piston.

[@NaturalBBler]

@@EVLS10 no its not

[@WORDFLESHGOD]

Could that design improve power on a mini digger?

[@clypeum5063]

The force Output will be Higher (its Always pressure*surface area) but you need more Hydraulic flow. Its only Advantage over a bigger cylinder is the Formfactor. You wont gain anything by using this on an excavator comparing IT to a regular cylinder with the Same surface area of the Piston (pressure*surfacearea).

[@carni5064]

The only reason to do this is to get more power from the same pressure when you have cylinder diameter constraints. On a mini digger, this would be pointless because you could get the extra power needed by going with a slightly larger diameter cylinder off the the shelf.
