Ok last couple of parts. The first one is the pulley. I started by profiling it.
Then the center was drilled for the retaining screw and parted off.
Next up is the flywheel. I dinked around with Tinglet's flywheel tool until I came up with something I liked.
The flywheel I came up with is actually wider than the grip area of the crank shaft so I decided on having a center hub on only one side.
I marked out and trepanned the side without the hub first.
Then the part was flipped and the hub side completed.
The the flywheel was mounted on the rotary table and corner holes drilled. I should have added some additional clamps because I got some rotation of the part although it wasn't apparent at the time.
I did add additional clamps before milling out the edges of the spokes. Unfortunately it was too late. If you look you can see that the angles are slightly off on the intercept. In the end it wasn't a big deal but it did make for significantly more clean up at the end
The outer curve was then cut and the part trued up on the lathe.
That completes the machining on this project. Now it's all about fitting and finishing. I'll end this log with a final family shot.
Next time you see it will be in the showcase.
Till next time
