Five Cylinder Wobbler Plans

[vederstein]

I guess I just could have just made one of the existing designs for the "hula" engine, but I went ahead an designed my own.

If for no other reason, this just shows that there's more than one way to design the same outcome. So if anyone says something is the "wrong way", well screw them.

I hope you enjoy the plans. At some point in the future I'll be making this motor.

All well and good - what does it look like?

 

[vederstein]

The assembly drawing has the engine, but here's a screen copy of the final assembly.

looks a good idea, don't you need a single inlet manifold, (piece of pipe) and a separate outlet manifold. So the cylinders run in parallel, instead of in series. It would still run as shown but on steam would not be as powerful, as each cylinder having its own supply of steam. As the steam would loose pressure and condense as it passed between each cylinder, to the point where the last cylinder would be running on very wet steam.

perhaps mill a section on the lower mating surface of the piston to form a grove to line up with an exhaust port on the engine frame, which in turn is connected by a separate pipe.

I like your plans though, a very interesting design

 

[vederstein]

Thanks JC.

This design is really to be compressed air only. I'm using polyurethane tubing and barb fittings from Clippard Labs. Those components won't hold up to the heat of steam.

If the cylinders are starved, I can make more taps into the tubes.

 

[JCSteam]

I may just adapt and make your design given time to make an engine that runs on steam, I like the proportions, the cylinders been the same outer circumference (or near as) to the the flywheel

Uhhhh... It looks just like the "Liney 5 " I just completed last year . Just sayin' . :fan:

 

[vederstein]

Yeah. I'll admit the concept is not much different. You would also say that one mill engine is just like any other. What is different is how the machine is built up.

The biggest difference is instead of the frame being one very complex piece. I've designed it as six simpler pieces which are screwed together. I've also used commercially available components (screws, shoulder bolts, air fittings) where it made sense. This design is not meant for a master. It's meant for a someone with a lower skill set.

i.e. - I designed it with my tooling and my capabilities in mind.

Bye.
