Can A Hydraulic Ram Work As An Air Engine Piston?

[@morgangray4278]

Being a serious steam train nut, and familiar with tractor hydraulics and rams, watching this project is a real joy! It really brings all sorts of passions together, and in a relatable way! I can't wait to see the process of building some sort of regulating valve... a Walschaerts valve gear perhaps? something of your own invention? On to the next thrilling installment!

[@graysgolf]

Well said, I too can't wait either. Like your surname aswell

[@datguymiller]

Well walschearts valve gear is like really hard to make Stevenson's would be easier

[@lesstoneuk]

A simple push button valve will do fine. You should be able to set it from the crank via a rod or bar. This'll work fine with air but not so good with steam as steam will expand in working but air just pushes. Also, you have to find some way of exhausting the air in the cylinder while the piston goes back down. Good luck

[@pvtimberfaller]

It’s designed for steam power so I will never be esp efficient, but never mind, it is pretty easy to make something go round & even get some usable horsepower out of it if fuel economy isn’t a concern. I think the biggest limiting factor is probably port size. I would simply add a fixed valve (rotary?) and use hydraulic hoses to pipe the steam to the cyld.

[@databang]

I enjoy the way you pace your storytelling.

[@jpsimon206]

If you guys have some old broken down agricultural equipment laying around, hydrostatic transmissions are a great source for homemade engine parts. Most of them utilize a squash plate against six cylinders with pistons actuated by oil. These systems work bathed in oil so they are often in very good shape even if the overall machine is not. There are some surprisingly tight tolerances in there, I have made several Sterling radial engines out of smaller ones, from riding mowers

[@matthewsmade]

I love how your always so surprised when something works

[@Chlorate299]

Yeah that'll work pretty well! - taking a leaf out ot the steam engine book, now you need some sort of eccentric connected to some sort of shuttle valve. Careful with oil lubrication though, you might end up with an impromptu diesel engine if your valve timing fails and the flywheel compresses the air in the cylinder. Some sort of silicone oil may be the answer there.

[@Convolutedtubules]

Great comment!

[@wayoutwest-workshopstuff6299]

Ha! Brilliant : - )

[@RubyRhod]

I'm a mechanical engineer in germany for agricultural machines. My biggest mistake I ever made was accidentally blocking a hydraulic cylinder from pivoting (in a prototype). So basically the piston moved out, tried to follow the thing it was pushing, but the bottom part couldn't move. So the rod had to bend. It bend roughly 30-40°! It was bent like a banana! No oil leak, it still moved in and back out again and I had the shock and laugh of my life all at once. Pretty damn sturdy those things. Not all of them come with 2 holes; often the rod is threaded and sometimes the cylinder has a bolts welded on the sides to move the pivot point closer to the seal (i.e. dumper do that quite often). By the way, I almost always like the shapes of your plasma cut sheetmetal parts. I recon they must look "natural" (rounded shapes) and yours always do. Structually it usually complies with stresses if the part looks like it "grew" (like a tree).

[@jamesgoddard8375]

Brilliant stuff. Ok I'm looking forward to seeing your progress on this project.

[@railfan439]

A very simple valve is to have the flywheel shaft running through a long(er) bearing, with two adjacent air ports and a flat spot on the shaft. When the flat spot lines up with the air ports, the air passes through. Timing is adjusted by turning this bearing to different alignments. It can also be aligned for reversing. Thanks for the video.

[@wayoutwest-workshopstuff6299]

Yes, there are a few types to choose from

[@lumotroph]

Lovely to watch!

[@FlyingRivets]

wow you work quickly!, you might want to look into working the steam expansively, small bore/long stroke cylinders make for horrifically inefficient steam engines with very little power! Big thumbs up, excited to see what happens next!

[@pieters286]

you mean something like turbine?

[@FlyingRivets]

@@pieters286 I hadn't actually considered a turbine, I meant in terms of the cylinders proportions since with a larger bore you only have to inject a little steam at the start of the stroke, then as the steam expands into the cylinder it pushes the piston through its travel. Given how crude yet successful early steam engines were I don't think leather piston rings in a plain steel tube for the cylinder is out of the question or since tim's so handy with the laser cutter maybe even laser cut rings?

[@pvtimberfaller]

No, long bore worked expansively is the most efficient way to use steam. Look at stern wheel engine design, 8-12”(?) bore & 6’ stroke or something to that effect. The stroke limits the RPM. Bore & Stroke trade off torque & horse power. To answer your question, no, plasma cut parts are way too rough to seal & the slag produced on the cut edges would score the cylinder instantly.

This makes me think of a place where they made the break point on the coast have channels that the waves could hit and blow air through with the waves crashing into them.

I would suggest a cam on the main shaft. If you attach it with a set screw you can adjust the timing until you get it right. Then all you would need is a little bracket to hold the valve in the right spot.

[@tomtruesdale6901]

What a wonderful machine. Maybe mount a lever or three on the flywheel that would press on the air valve as they go by giving a shot of air to the piston? You might need to figure out the speed you wanted the flywheel to turn at...I think. You would have to start the flywheel turning by hand but that should not be an issue.

[@sebbes333]

*@Way Out West - Workshop Stuff* MAGIC VALVE-ish: The timing is directly tied to the rotational position of the flywheel, you could add a kind if ramp & similar to the flywheel (add counter balancing weights too) for the length=duration that the steam needs to be added, then have some kind of button-like thing that gets pressed in when the ramp is in the right position which lets in more steam.

[@HisnameisRich]

I must say Tim you are a lesson in positivity and rescourcefulness! Bravo as always! Could you not have a non return valve and vent to atmosphere on the two inlets/outlets so that you could use both strokes? I.e on each inlet/outlet on the ram have a manifold with 3 routes, one to the ram, one to atompshere and one to the air source, a non return valve on the air source side would allow the ram to vent to atmosphere on the outstroke and allow air in for the power stroke? an unneccsary complication maybe but it could be achieved with some standard plumbing/air fittings? Just a musing more than anything else!

[@eckosters]

The bird song was my favourite part :)

[@portblock]

Ah finally an area I do have knowledge, lol - I was a hydraulic engineer in my early years, I use to design pumps, cylinders and valves. a simple valve you can make would be a spool valve. You can make simply like this: Steel rod, say 100mm long, and turn down the middle, say for a width of 30m, so you would have something that looks like ===---=== , then take a piece of square stock and tap 3 holes in a row on the side and run a hole through the middle. the idea is the spool moves back and forth and only connects 2 of the 3 holes at a time, so the center hole goes to the cylinder, the other air pressure and the last one is exhaust. hope this helps some. if it doesnt makes sense, check google images for "simple spool valve"

[@Mafanwe]

thats fantastic! so exciting!

[@liamholcroft7212]

Could you use the sxhaust near the top of the piston to activate some sort of valve at the bottom? maybe using a membrane and a pin like on a turbo blow off valve.

[@ianbottom7396]

You’re going to need a 3/2 valve, that is 3 port, 2 position as you need to be able to apply pressure on the extend stroke and vent as it retracts with flywheel rotation. Simplest way is going to using a cam arrangement on the shaft which actuates a 3/2 valve

[@egoncasteel]

I knew one of the comments must mention using a cam kzbin.info/www/bejne/oanUnqaXlqmZmqc

[@juliancripps1580]

Perhaps you could make the rim of the cutter wheel in to a cam, to lift valves to power the ram. As the the diameter is large the rotation would be slow and it would be easy to tune up the timing by moving ‘ramps’ around the rim. They could be clamped on to start with. Just a thought . Carry on the great work. Thanks.

[@nathand3stroyer486]

Great job buddy

[@rronmar]

Yep, you need a shuttle valve, something that will open fully to vent the reverse stroke air. Since it is already expanded in the cylinder, you want as large a port as possible so it vents compressing the air inside as little as possible so it doesn’t impose so much drag. It being a double acting cylinder, you could put one on each end port, actuated by the same rod and get 2 power strokes…

[@detectivesky6123]

I’d suggest using an eccentric on the flywheel to control the valve but many, many others have already said so haha

[@andrewcoffer]

I want to refer you to a guy named Corey Little. He created a very simple pneumatic valve design for bikes, and I think it would work nicely for your needs.

[@wayoutwest-workshopstuff6299]

Thanks, Andrew. I need it to be steam proof too, and that's proving a challenge.

[@BuzbyWuzby]

As an ex hardware control software engineer (in a former life) I would add a circular encoder strip to the end of the axel, or even a linear encoder strip along the rim of the flywheel, and then connect a detector to a PC / laptop / PLC which would trigger a series of solenoid controlled air valves at the correct times. Overkill? Well, yes. But if you programmed it correctly then it could very quickly 'learn' the optimum timings and be as efficient as possible

Tim, you need to position the crank much closer to the flywheel, there will be far too much bending moment on the shaft and wear on the bearings in its current state. As others have said, a valve activated by the axle or the rocking motion of the ram (as in a simple oscillating steam engine) could work the air/steam inlet. But you need to consider how to exhaust the driving air/steam as well...

[@wayoutwest-workshopstuff6299]

You're right, Tony - but I need to leave space for the drive sprocket, as well as the valve gear, so I thought I wouldn't cut anything off just yet. Any ideas for the exhaust? I was thinking a sliding plate over a hole in the cylinder, but I don't want to mess up anything

@@wayoutwest-workshopstuff6299 Tim, I'm thinking a simple shuttle valve operated by an adjustable cam on the axle (or the edge of the flywheel?) or a rotary valve, much like a faucet but with a 3-way hole, to both cut off the air and let the exhaust out.

Take a look at the mechanism they used to keep a propeller airplane from shooting off its own propeller in WWI. Should be 'easy' to do the same on this engine, and have the air valve open and close based on the position of the shaft. Same cam should be able to work 2 valves, one for supply air, and a second for an exhaust port. You can make 2 cam rings that can be turned slightly to have adjustable timing for each. Make it 4 rings, and you can have adjustable timing for input and exhaust for forward and reverse. Supply air control valve will act as your throttle.

[@wayoutwest-workshopstuff6299]

Yes, that's pretty much what I'm going for now (though I tried something else first!)

[@PaulRansonArt]

How about making a clamped on lobe ( like a camshaft lobe ) and slipping it on the flywheel shaft and mounting the compressor blower valve under it. Then its a matter of adjusting the timing to blow air in when needed. Just like when you did your first run and opened the blow pipe using your thumb. 😄

[@RussellNelson]

2:48 No, they don't always have holes at both ends. This is a "double acting piston" meaning that it can pull as well as push. My International 340 tractor had a manure bucket with single-acting pistons, meaning that it could pick up the bucket but not push it down. That relied on gravity.

[@RC-nq7mg]

I think by holes at both ends he means the anchor points.

[@TheDiner50]

I think he meant the mounting holes. One being on the end of the piston and one at the bottom of the case. Thanks to this the piston can move making the cranking of the flywheel possible. Usually hydraulic pistons are built to allow the movement to make buckets or really anything needing hydraulic lifting arms possible. They do more then just "push out" and "pull in" for most tasks. They have to move up and down in there mounting points to make them useful. But there are pistons that only push in and out without the mounting to allow the movement up and down. But really they are kind of rare since the applications that requires only a pull and push movement are few. The extra mounting length of the piston is barely anything so even if you do not need the up and down moment, well. To make a piston with the mounting being on the rounded cylinder is just not needed in so many cases. Better to stick with this kind of hydraulic cylinder so you can find replacements easier when needing to repair it. Rarely do you see any other pistons design outside of small air driven ones or special use cases. If the space constrains are REAL, Like having a locking pin pushed into a door or gate whatever you barely find anything but pistons with a single cylinder or extendable multi cylinder pistons. (telescoping piston) With basically the same mounting and movement possibilities outside of special use cases that are really not worth talking about. Yea double acting and singles are a thing too. But really outside of telescoping or single cylinder pistons the differences are sizes. Basically. Mounting points are as they are for a really good reason.

[@russellsmith8609]

If you had, as in could make, a diaphragm with the same volume or slightly greater as the cylinder you could have oil on one side and steam on the other. As you do have a magic metal cuter.
