I completed the first pass on the Steam Engine technical drawings a bit over a week ago. These are 2D drawings that specify each of the parts that make up the engine.
This is a fairly major milestone in the steam engine project, since it enables CAD drawings to be created that match the dimensions in these drawings. Work still needs to be done, however. There are likely to be errors in these drawings that need to be weeded out. Bolt holes need to align, for example. Nested parts need to fit. Etc.
I’ve already started a review of the drawings, but I’m also open to other people looking at them for potential problems. I’m also looking for ways to further simplify the engine for fabrication and assembly. Efficiency and power suggestions are also welcome, but radical changes to the design will be deferred to future versions.
There has been some discussion of building the first prototype of the steam engine at Factor e Farm in July or August, but if you would like to try your hand building one, contact me so we can work together. We like to capture early prototype development efforts in photos and videos.
