Potty Over Crank Wall Engine

Stew, regarding the attachment problem, there was a technical problem with the site. It is supposed to be fixed now.


That is one mighty fine job you've done on that engine. :bow: :bow:

I can't offer any help with the posting attachment problem but it sounds like it is fixed. I would really like to see the drawings. That is a really interesting looking valve/governor setup.

Hi Jerry that seems to have worked now.

The Governor and Butterfly valve are linked together with this little link arm.

I've not drawn it up yet I was unclear of its shape or how to make it, I just did a few rough sketches then started to whittle a lump of steel down until I got something that worked.

I havn't done an assembly drawing yet showing how the three eliments link together, I think a side few would show it Best

Spent best part of today cleaning things up and slowly assembling the engine couldn't resist an how's it looking shot.

To bring you up to date.

Rebuilt the engine and completed the governor pulleys, I've run it on the test base for over eight hours now and its runs sweet.

The governor sort of works found that the butterfly valve spindle is fouling the frame, and I think the return spring is too strong, so that will be stripped down and I'll do a bit of experimenting, when I've got it fitted to a new hardwood base.

Here's a few beauty pics to be going on with, I'll post a video when I get it on the new base.

What an amazing looking engine. The crank, rod and crossheads will make for interesting viewing when running. Waiting for the video.

Thanks for your comments Guys.

Not sure how it would run on steam, The air ways are a little narrow so I figure not so good, but I've no plans on running it steam anyway.

Cheers
