Maudslay Marine Oscillating engine
« on: March 08, 2019, 11:38:24 am »
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.

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.

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

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

Love the engine George.

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.

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.
