Jerry Howell "4-in-1" Atmospheric engine & mini propane burner

Attached is a pic of the Jerry Howell "4-in-1" Atmospheric engine & mini propane burner I just completed.  I built it as per his plans except for the flywheel, which I built using ideas I have been kicking around for a while.  The base is Corian with pearl dots inlaid.
 

It is an atmospheric or more commonly referred to as a "flame licker" engine designed by Jerry Howell.  It has a 1" bore & 1 3/8" stroke.  I built the air cooled, side crank version. I built it as per his plans except for the flywheel. I built the flywheel using an idea I had been kicking around. I increased the flywheel diameter  from 4" to 4 1/8".  Instead of an all steel wheel I used an aluminum hub & spoke outer rim. I then used a steel outer rim  The spokes I made of brass.

     

This engine was built using a Sherline 2000 mill & 4400 lathe.  The air cooled cylinder & flywheel was a stretch for those machines, but I got 'er done. The plans call for cutting the cylinder fins using the lathe, but I couldn't come up with the necessary tooling so I cut them on the mill using the rotary table. It was quite time consuming, but after all it is a hobby.
