Bernay Steam Engine CAD Drawings

[JorgensenSteam]

I had a request for CAD drawings for Bob Jorgensen's Bernay steam engine, so I began making those yesterday.

Pat,

Thank you for documenting this engine. It looks to me quit a challenging project.

Highest regards,

SAM

Pat,

You are a busy fellow.

Just a suggestion, how about adding the photographs and other documentation to the PDF drawing file.

Thank you so much for documenting this interesting engine.

Regards,

SAM

Here is an other photo of the Bernay disassembled.
The proverbial "box-o-parts".

Pat,

A picture is worth a thousand words. Are there other parts that are not in this picture?

Thanks,

SAM

Great set of pictures, Pat.
Should be a great help for anyone wanting to build one of these fascinating looking engines.

Sam-

The only thing not shown in the box is the wood base.
I did not get time to roll all the photos into a PDF.
Depending on the resolution, it may be a big file.
I can email it to you.
Can you receive a large attachement, like 10+ mb?
If not, I can cut the resolution down, but the high res photos make it much easier to study the engine, since you can zoom way in without loosing resolution.

Pat, I don't see the cylinder block, but have seen it in the other photos you posted.

Pat,

Thank you for the photo's. They really help me to understand how the engine operates.

The Bernay drawings are almost complete. - Pat J

Uh-oh . . . Someone beat you to it (Webtech Services LLC © 2006), but that's OK maybe yours will be a different interpretation. A model from the drawing excerpted below was built by Jesse Livingston of Troy TN. I think Jesse's Bernay's engine was written up in Live Steam Magazine but I'm not sure if it was a full construction article or a photo description article. It's a very attractive and interesting engine.

Pat,


Thanks for the drawings. After I finish up some things I'm working on, I intend to attempt building the Bernay engine.

Thank you for documenting this engine so well.

Regards,

SAM

Pat,
Thanks for the history and it's great to have yet another nice engine added to the world's library of designs.

Hi Pat,

Great looking model...I was just looking at Jesse's prints ...thinking the same thing everyone else is, when I found this thread.

We'll talk.

[steamer]

Ahhh Slip eccentric, as I suspected....that should be easy enough to implement......

An incredible job on the plans Pat. I'm looking forward to all the build threads starting on this one. :bow:

Ok Guys. I'm the one who started this string, I think, but I'm not sure how to reply or add a question. Hope I'm doing it right. HELP!

My current problem is this. Drawings B-8F and B-8G show the valve gear rods and the quantities for all. 6 rods total. But look at drawing B-8L. it shows 3 long rods, not two. Plus the upper and lower long rods on the right are different lenghts BUT I can't find a drawing for it. Am I missing it somewhere? Please set me right and supply a dimensioned drawing if that's what I'm missing. Much thanks Guys! This engine is a real challenge! Swift 752 Bob

Drawing B-8H has rod #4 which is slightly shorter than the two on drawing G, if you look at drawing L you will see two are tapered (#2) and one straight (#4).

Jason: ok. Problem solved. I DON'T have a B-8H! What's the easiest way to get it? THANKS for the help. Thought I was going nuts. Come to think of it, there's no B-8I either. Jumps to J. What else am I missing? Swift 752 Bob

I've got Jesse Livingston's plans right in fron of me if you need anything...I could scan the drawing you need if that would help.

I've got a page here with 22 fasteners on it (bearing stud, valve box stud, valve stud, etc)

 

[Jasonb]

Bob, PM me your e-mail.

Latest drawing set is revision 12.

Ok Guys. Got her built. Now I'd like some help in timing her. Seems to me the most critical and first thing to do is to get the eccentric properly placed on the shaft WRT piston position. The rest should fall into place . Any ideas? Thanks! Swift752 Bob

Maybe it's just me, but I didn't see plans or pics of this engine anywhere in this thread. Is it just me?

So, I'm curious of course... Can somebody link me to the plan set and pictures so I can see what it is?

Thanks!
Chris
