Cylinder heads have been re-bored to accept new full length valve guides. New valve guides have been fabricated and installed in...

I've ran into a problem here with how well my valves seal---or not. Every previous engine I have built used full length "valve cages" in...

Do a web search for Elmer Verbourg. He designed a whole bunch of different simple steam engines and most of his designs are...

Okay, for what it's worth---The new threaded insert is in place. In the picture you can see a "driver" that I used to screw the insert...

The sparkplug thread repair is under way. What you are looking at is a piece of steel threaded 3/8"-16 unc on the outer diameter and...

Today I made the nylon points mounting block, the brass ignition points mounting assembly, the ignition cam and opened up a few...

I'm getting down to the short strokes on this engine. I still have to make cams, valves, and an ignition point system. The valves are a...

Thank you, Vietti. That is a very novel idea. My engines are only ran at low speed, so I don't anticipate issues with the pushrods. I...
