Vederstein's Five Cylinder Wobbler - Finished!!!

[vederstein]

I'm considering my version of the "hula" engine done. This engine was of my own design. The action of the engine was others though.

It's not perfect, but then I'm not a perfectionist.

I didn't really modify far from my original plans (here). I believe if one followed the plans explicitly, they would have a running engine.

This wasn't a super hard engine and would be a good project for someone that's done a couple of single piston steam engines.

Fantastic job. I can see why it's a 'hula' engine. Thanks for the plans, one day I'll have a go at one.

Neat engine! Thanks for sharing. The colored hoses go with the hula theme lol.

I love these 'Old Style' engines.

It was what this site started on, bar stock engines, and it allowed almost anyone to have a go making one.

But of course, things get better and people improve and so much more complex engines are being made and shown.

In fact in the early days we had to have a vote whether we would allow engines from castings to be shown.

Nice one V.

That is neat, and it looks like it runs very well.

Thank You for posting,

I built a magnetically sprung V4 wobbler a while back

But I really like your 5 cylinder configuration.

I have not thought of that - well done.

Its interesting to look at - self starting and a nice runner - definitely one for the future project list.

Regards, Ken

Thank you all the kudos.

I've been watching your creation as it progressed Robert. It looks WAY cool running! Something to be proud of for sure.:thumbup:

What pressure does it run on?

 

[vederstein]

As seen in the video, it will self start at 18-20 psi. With a bit of help, it will run on 10-12. The cylinders are single acting so it's not as powerful as one might expect for a five cylinder steam engine.

My biggest screw up is on two of the cylinders, the chamfer on the back is too big. Therefore pressure ports are open to atmosphere at certain times. Therefore it wastes a lot of air.

I could remake the cylinders, but I just don't want to. As I mentioned above, I'm not a perfectionist.

Thanks,

...Ved.
