Hi George, That is a beautifully crafted gear set and governor you have made.

I know it would change the look..... However if you remove that weight out of the center of the governor, your balls will rise easier and at a lower RPM.

cutting your own helical gears... Incredible 😉

I completed the governor for the engine. The helical gears were cut with my home-made fixture. The tiny bolts are M1.0 x .25. There's just not enough weight in the balls to get it to work effectively. I guess there's a limit to centrifugal force. It looks neat spinning up there so it adds  to the character of the whole engine.

Maudslay had a lot to do with the "modern" lathe, rite?  Whitworth was an apprentice.

Love the engine George.

Thanks George, it gives the flywheel a classic look very much like the twin cylinder one sold a few years back
Mr Fellows made a nice job of the design
cheers

Hi Frazer,
To cut the 45 degree chamfer on the flywheel I have a variety of end mill ground with 30, 45 and 60 degree angles. I cut the sides of the spokes first then matched the radius with the chamfer in the corners.

That is very nice and love the extra detail in the flywheel. Did you make youre own cutters?
best wishes

A gentleman named Chuck Fellows saw pictures of the real engine and turned it into a miniature. He freely posted the drawings and I built it only in .70 scale from what he created.
