It is the time for the next project. This time I have selected the Potty three cylinder air engine. Plans can be found on this site. I will be making some relatively minor changes to the original design including not using metric screws. I have modeled all of the parts and produced new drawings...

After my last project that took mounts to complete I wanted something that could be completed quickly. I also wanted a project that used material and tooling on hand. After looking around I selected Elmer's Tiny Engine. I made some minor adaptations to use material I had. I changed the 1/16"...

I am calling my beam engine finished. The build log for this engine is located here http://www.homemodelenginemachinist.com/index.php?topic=10691.0 I picked Gerry's Beam Engine because it would require working at a smaller scale than my first engine. Overall I am pleased with the results of my...

On my current build there are a number of 2-56 blind holes. I was having difficulty getting all of the swarf form the holes. Compressed air did not work well. Repeated running the in, withdrawing it and brushing off the swarf was time consuming. I came up with a simple tool that I find helpful...
