Looks great. What is it? :)
Inquiring minds (at least one) want to know.

They are some parts for the Bernay engine I've been building.
If you follow the link, you will see it running.

Got to figure how to post the video on here without the link, if possible.

That's pretty cool.

A heck of a lot of parts moving....

Some background on the engine design:

Yes, I've read that before.

I really like all the moving parts. Now to balance it and finish it. Still debating what I'm going to do.
Thinking of painting the main brass body. I'd like to nickel plate some parts. Obviously, the stainless parts will just polish up.

That's a thing of beauty Sid. Quite an interesting motion to it, very therapeutic. Thanks for sharing.

Well that has finished up rather nicely Sid!
Bead blasting can make for a nice contrast. A matte finish via Scotchbrite sometimes looks quite nice next to polished and is easy to keep maintained.
Too much 'color' contrast can occasionally work against you, but as you have an excellent sense of style (perhaps that mostly means it parallels my own : ) I am confident that perfection in aesthetic balance will be attained.

You have built a Twerking motor! I really like what you have built. Great job.

Beautifully done engine! It's a cool design I haven't seen before, and has a very pleasing and smooth sinusoidal motion to it. The craftsmanship is excellent, as well. Thanks for sharing. It's a mechanical work of art.

Ah HA, perhaps that's why it's so soothing to watch lol

Agreed!

I have so many engines with brass components that I could spend weeks polishing. I love the polished look but sometimes its just a pain in the ass to get into places and keep them looking good.
This engine especially.

Yeah, everyone that sees it run seems to say the same thing: "that's so mesmerizing to watch!"

Thats beautiful to watch. How much time is invested in that.?

Probably three months, on and off as time and other people's projects allowed.

This type of engine is petty to look at, but did the design ever have any practical application?

I don't really know. Other than the link that JT posted previously, I've not seen much history on the design.
I can only think that it was too complicated to make it into wide use, especially when more conventional designs were competing.
Still, it sure is fun to model ad watch!

BTW, it's 15.87 lbs!

Will run down to 30-40 rpm right now. Maybe slower once I balance it a bit??

It's ocean-like wave movement - something I really have not seen in an engine although some of the swash plate designs kinda have a little of that going on in a different way - it is very cool thanks for posting Sid and nice quality work once again...

What powers it?

What powers it?
In this case, air. However full scale, steam. As could this one.

With the workmanship we watched going into the parts, was there ever a doubt how well it would run?

Outstanding !

That is a thing of beauty. With all that "Monkey Motion" going on you won't need a Shaper to entertain yourself.

Well there was a bit of a challenge timing this one. I actually timed and adjusted it one cylinder at a time.
