wonderful. and thanks for showing the way you hold the parts to machine them.

Very cool.

We are surely going to want to see a video of that operating!

It's probably going to be a while. I work on it in between getting everybody else's projects completed.
As noted in the other thread, this engine will be terribly out of balance, as is. It was designed as a low speed engine.
I do plan on adding counter weights to the crank. An air driven engine definitely runs different than a steam driven engine.
Lower speed capable with steam, without stalling.

Looks good enough for the dust jacket of Steam and Stirling book 4.

Interesting design and your usual quality of machine work.

Funny you should say that!
I was recently asked for permission to reprint my Slant Engine (NOV/DEC 2005) in the the S&S Vol 4
BTW, that engine was on the cover of that month.
My Vert 1.5 x 1.5 engine was in S&S Vol 3, on the dust jacket.

I feel very honored when I get published in any form.

That workmanship is simply stunning ! PLEASE do post more often !

[Mcgyver]

thats a good looking engine Sid

[BCRider]

So THAT is what the mystery item from the other thread is becoming ! ! ! !

And I got to agree that it would be right in place gracing a front cover of any book or periodical. Truly lovely work.

And yeah, I'm with the others that said it'll be great to see a video of it running. That's some serious "out of the box" thinking that went into that design.

[sid pileski]

Yes, at some time, many years ago Bernays was thinking outside the box. I thought this would be a nice engine to build. Lots of motion, with a good flywheel and some balancing, it should run reasonably slow.

Very nice work Sid,look forward to see it run!

[sid pileski]

Thanks!
