I have been wondering ever since I built the hit and miss version of Chuck Fellows engine, what I could do to present a load that would increase and decrease to show the governors kicking in and out and affecting the "Hitting" and the "Missing" of the engine. I believe I have come up with the answer to that in the attached video. There is a slight offset delay between the load being presented to the engine and the change in the firing pattern, but I think that is either because the governor needs a bit of time to react to the engine speed, or possibly because when the engine "Hits" the drive belt slips a bit. It is an interesting video, and the package will show well at a steam fair when I run it and all of my other engines and the machines they drive.---Brian
 
Nicely done, that variable load certainly shows off the governor's function. :bow:
