I have enough progress for another post. I'm getting close to a working engine. When I left off I had to redo the whistle assembly. That's now complete.
Now on to the last part. I started by turning a flywheel blank.
Then the area between the lines was trepanned out on both sides and the center hole was drilled.
Then it was over to the rotary table where the corner holes where drilled based on Tinglett's flywheel tool.
I started to cut the spokes when I realized the angle off on my rotary table. So much for that blank.
On to the second attempt. This time I successfully milled out the edges of the spokes.
Then the rest of the waste was milled out. I think It came pretty well. This flywheel required much less cleanup than my last flywheel.
The last operations were to drill and tap a hole for the set screw.
Here is the final family shot.

It's now onto fettling and finishing. I decided I was going to hot niter blue the steel parts. Last time I did this someone asked what the temperature was in the pot. So here is a picture just prior to blueing my first part.
Here is a picture of the blued parts after hardening overnight.
The next post should hopefully be a running engine.
