I have two PM kits. They are nice kits. I have yet to work on them. When I bought them I also bought spare fly wheels. I am using one on my Mine eng by Elmer. I did have to pay for their catalog.

I'm on my second model from P&M Research they are great to deal with and very helpfull. I thing we all should try to support a american made model. You can get a governor kit for PMR model #1 from Eclector Devices Inc po box 66 lakeview, NY 14085. I found him on ebay

I have finished the PM model 3BI. It was my first kit eng. and it is a lot different from bar stock eng. You have to spend more time figuring how to hold things. With bar stock you have a foot of metal chucked up and make the piece and then cut it off.
I was happy with the eng. It is the first eng I have made that will run of lung preasure. You might turn a little blue if you do it to long.

HI
Just had a look through my list. I have almost 25 companies listing kits from castings in the UK. These range from kids oscilating engines to 4 inch road locos.

That brings up an idea, a section listing suppliers. Just an idea.

cheers Kevin

CD:
we do have the links section that would work well for posting links for engine suppliers or if it is all engine casting suppliers just post the list of links in the Engines from Castings section.

I wonder if that governor would be big enough for the PMR #4. I recently bought the PMR #4 castings and would like to fit a governor to it.

How much does the Eclector Devices governor cost?

Thanks for the tip.

I found the governor listed on eBay:

There are a lot of pictures of the governor installed on a Stuart S50. However, it's clear to me how it regulates the speed of the engine since it doesn't seem to connect to the steam supply line. Can someone explain how it works?

Hi Chuck,
Looks like some sort of pseudo governor, as the engine speeds up, centrifugal forces throw the balls outwards thus causing the governor to slow down and so effectively slows the engine down by putting a heavier load onto the flywheel output.
Not the real thing, only looks like it.

Isn't there an arm that goes into the steam chest? Maybe there is a rotary type valve in there?

 

[compound driver]

HI
Thats a Pickering govenor! it works by turning a rotary valve in the steam way just inline with the steam regulator. The pulley takes drive from the crankshaft and does not load the crank.

On a traction engine the pickering lowers or lifts a plug that seats in the regulator to steam chest line. ON mill engines it almost always worked the way the one on Ebay does.

The other option prefered by some tractor makers altered teh valve cutoff. Not as fast and not certified for generator use.

That all said with balls that small I doubt it would work that well or that fast. junk the brass and cast a couple of lead balls! Should work fine.

Cheers Kevin

I wonder if the governor shown on the Stuart-50 is the same as the one he shows on the PMR #1 engine, eBay item 190174357789 The are not identical, but they are very similar. It looks like they could be variations of a single design.

The one on the PMR #1 engine seems to have a connection into the valve box. I wonder what it does in there.

If you look carefully at all the pics on ebay, it isn't connected to anything other than the flywheel and there are no steam connections either, so unless they have invented invisible copper pipe.........
Also his other engines with this governor on has no steam connections to it either.
This just might be an expensive bag of junk that you could knock up for a few bucks.

I have sent him an email, so will post the reply when I get it.

HI Orin
Dont know if my post is invisable but I did describe the govener and what the bit does that goes into teh valve chest.

Cheers Kevin

 

[Bogstandard]

Hi Kevin,
You know that and I know that, but the chap on ebay isn't showing that.
I have contacted him and he is being a bit cagey.
I am replying to Chucks request as he couldn't see how it worked on the ebay item.

Thank you for the explanation, Kevin. I appreciate it.

No, your post wasn't invisible. You'll notice that our two posts were only six minutes apart. Yours came in while I was composing my question, so I didn't see it.

Best regards,

Orrin

I have completed the Oscillating steam engine kit # 2A . It was a fast Eng. to build. The casting were good quality.

 

[wareagle]

gt2ride, that is a great looking engine! There's just something about the appearance of a cast engine that is just neat.
