I've always wanted to attempt to build a running engine of wood.
Hard woods such as oak can be cut very cleanly and accurately with
metal working tools.
Tonight I decided to get started.
7 minutes in the shop produced this rough wobbler cylinder.
This is design on the fly!
It was a 1" oak dowel that I chucked up in the lathe and ran a 1/2" 2 flute
center cutting end mill in to. The bore is very smooth and mics at .507"
When I used up maximum depth of the end mill the bore was 1.147 deep.
I'm thinking a 3/4" stroke will work well in it. I can make the crank throw from
a piece of the same dowel. Tomorrow I'll make a trip the hardware store to buy a
couple of smaller oak dowels and see if I can make this idea fly...
