HOW MODEL STEAM ENGINE GOVERNORS WORK

How Model Steam Engine Governors Work. Centrifugal Governors that regulate the speed of Steam Engines are quite simple yet clever devices.
In this video I show how they work starting with this one that is fitted to my Stuart Victoria Horizontal Mill Engine. / keithappleton

Lovely balls! No seriously, thanks - I wondered how they worked.

[@Kevin-go2dw]

Many years ago, I was operating a traction engine (Foden 1700) driving a saw bench. I could watch the governor and listen to the exhaust beat as a log entered the blade and when it exited. I could also observe the water level rise up in the glass as the balls went down and the exhaust got sharp and loud as the saw started to cut and the reverse as the material left the blade.

A steam plant under load video utilizing the three ball version would be very interesting and educational. E Well done as usual.

Hey Keith, I was testing my steambike the other day and I had big problems with the gas cannister freezing up. I use Coleman c500 gas cannisters, and as far as I know the cannister was quite full still. Do you know any ways I can prevent this? The tank cannot be mounted near the steam line or burner for safety and logistic reasons. Cheers, Thijs.

Try putting the gas canister is a pot of cold water and direct the water gauge blowdown output near to the pot of water . . . . . . an occasional blowdown keeps the water almost warm but not hot, just enough to prevent chilling.

I was running my Wilesco Model Steam Engine a couple of months ago, and suddenly the governor drive belt snapped. I have not been able to replace it yet because every time I look for a new one, they have been a straight belt not attached. Do you know where I can get one that is attached at both ends or how I can attach the ends to make it a circle?

[@keithappleton]

They are all like that - not in a loop, you simply twist one end inside the other . . . . . .

[@jonesthesteam]

@@keithappleton Thank you. I’ve just tested the snapped band using compressed air and it works very well. I thought it was broken and I was going to have to get a new band. Thank you very much!
