[Brian Rupnow]

Tel--Absolutely loverly!!!!

Tel,

Keep meaning to say what a great governor

How big is it

And how did you cut the bevel gears

Best Regards
Bob

 

[tel]

That reminds me, I forgot all about digging out the drawings. To give you an idea, the bevel gears are about 3/8" diameter, and yes, I cut them on the Myford - hand planing with the topslide

 

[Brian Rupnow]

Tel--If you can drag the drawings out and post them or email them to me, that would be just great. What kind of steam/air supply valve did it operate??--a sliding valve or a butterfly valve. Did you find that it was effective and actually governed the speed of what you were running with it?---Brian

Argghh the dreaded gears - my hands have only just recovered! ;D

Brian, please tell me where you found the dimensioned drawing of the governor.

There is a story here- I have that drawing somewhere in one of my books. When I was doing the first show flyer for the New England Model Engineering Society [url]www.neme-s.org [/url] I found it, scanned it, and used it in the flyer. It later became essentialy the logo of the club- its on our Shirts, our show banners, newsletter and Ive even made engraved name plates several of us use at shows.

I want to make a model of it, but I can only find the scanned drawing, from which I stripped the dimensions to make it simpler for the logo.

Thanks for posting the link to www.neme-s.org. I have been over there for several hours and I know that I have barely scratched the surface. Steam, all types of engines and tractors, machinery, antique tools, Jet model aircraft any many many more. If anybody hasn't clicked on it yet I would advise them to if they like that type of thing and I think most on this forum do. I know that I have book marked it so that I can go back.

Thanks again Ron

cheers

Tel---A question for you. Did you find the flyball governor which you built to be effective in governing the speed of the engine which you put it on. And--how many cylinders was the engine it was controlling, and what bore and stroke?--A lot of questions I know, but stuff I need to know before I embark on a build if I make one of these for myself. Thanks, Brian

Well, yes, the governor worked quite well, but as I said, I did simplify the innards of it - just a simple plug moving up & down in a bore and covering, uncovering, the steam passage.

The engine in question is Jesse Livingston's Rocking Valve Mill Engine - 1" bore, 1 1/8" stroke - the cylinder on the is quite a compliacted piece, and was a lot trickier to fabricate - still, the finished product was well worth the effort.

Here's a couple of pics before and after silver soldering the fabrication, but befor clean up. Them porcupine quills are little bits of 1/16" brazing rod that were used to hols everything together and got cut off and disappeared during clean up.

Bottom pic is the complete engine

Thanks Terry.---Brian

While we're on the subject of working governors - here's another one I did, copied from an old illustration (engraving) of the Ames Automatic Cut Off Engine - it also worked a treat.

 

[tel]

.... and the engine it operates

at speed!

Look what I found!!! This is a casting kit by Art Dekalb in New York. It comes in two sizes, one with 3/8" balls and one with 1/2" balls. of course the one in the picture has been fully finished, but Art only sells the castings, apparently. I am currently wheeling and dealing with him, trying to get price and delivery.---Brian

 

[tel]

Now that is interesting! I shall be watching for the results of your enquiries with bated breath.

 

[Brian Rupnow]

I've been thinkin'---And thats a VERY dangerous thing---As Granny used to say---"Idle hands are the Devils workshop"---

 

[Brian Rupnow]

Very Dangerous---

 

[tel]

You got it Brian - 'cept you didn't show the spring!

Now picture the end of the spindle carrying a piston of slightly larger diameter, working in a bore to cover the steam inlet as it descends from the action of the balls. Much simpler than the version I sent you, and the way I did mine.

 

[Brian Rupnow]

Tel---I didn't forget the spring.--Its just that springs are a miserable thing to model. I just got an email from the guy in New york. His "Kit" sells for $20.00 U.S. plus $4.50 handling. Seems like a reasonable deal to me. He said that they come complete with sets of drawings. I don't see the brass balls in his "Kit" and I guess the shaft and gears aren't there either. If I don't have any real work tomorrow (which isn't looking too probable) I will go ahead and finish my design. I have a design here for the governor used on a Stewart model, which has no gears, just a pulley on the bottom of the ball bracket. It is driven by a 90 degree twisted belt off the main driveshaft, which would be ideal to work with my horizontal twin that I just finished.

Tel--Only for you, I put the spring in--- ;D ;D
