And brazed them together:

Cleaned the whole thing up on the lathe and drilled a center hole to suit the nail crank:

Installed a set screw, and mounted a new flywheel on the engine:

I've done a bit more to my wobbler after showing the video of the parts crudely mounted.  I think it's now more or less finished.

I've made a frame to hold the parts using a bit of pipe and some six inch nails.  A blob of weld holds them together.  The axle for the flywheel is another bit of 6 inch nail with a glazing sprig (a small wedge shaped nail used for retaining glass before putty) through a hole in the end to retain the flywheel.  That goes through the pipe and is welded on the back.

The ports were filed square and filed so that the inlet and exhaust opened and closed together at TDC and BDC.  The square edges also make the ports open more effectively.  That made it run much better.

Another chunk of six inch nail drilled on the lathe was used for the inlet pipe and that was silver soldered in place using my last half inch of silver solder.

A bolt was used to retain the bearing/valve/nut and fastened on the back with a nut.

Here's a picture showing how it looks now.



I can't make up my mind whether or not to paint it.  What does anyone think?

I'll do another video showing it running in this state in a day or two.

ps, I like yours without paint, Russell. but I'm sure it would look good either way.
