I've been doing different machinings on a small lathe and mill every now and then. My previous project was Ringbom-type stirling engine.
It succeeded so well, that I started to look for more challenge.
After seeing pictures of George Luhrs' engines at http://www.craftsmanshipmuseum.com/Luhrs.htm , I had to start to build as small four-stroke engine as I can.
I choose to build smaller version of Webster http://home.comcast.net/~webster_engines/ , because it seems to be simple enough for my first IC-engine project.
So far there hasn't been too big problems on building it.

Webster Engine
I too have started a Webster engine. It is a fun project and the only change that I made was to increase the size of the valve stems from 3/32 to 1/8 for ease of machining. Also I used a 2 piece valve assembly, 1/8 drill rod with the valve head cut from steel and silver brazed to the drill rod and cleaned up on the lathe. This is much more simple then trying to turn small drill rod between centers. I should be ready to run next week. Hope that helps a little.
