I am working on using 3D printing (mostly) to create the shell for O scale engines based on HO mechanisms. Sure .. this has been done countless times in the past .. in fact it is the basis of On30 after all. I’m working with Andrew Gillette on this – in fact the SD40-2 would be for him.

The current plan is to create ‘Road Engines’ .. similar to those Modern Narrow Gauge engines you see in South America and not so much the switcher conversions you often see. If successful I would like to create some RTV molds to make copies in resin.

I currently have the following HO mechanisms:

Intake Grille

Overview You can see what I wall call "Intake Grilles" on all locomotives. You see something like a screened opening behind which is some kind of filtration system to supply air to the engines. On many scale locomotives this is simply a cross-hatched casting that with a bit of dark wash looks like screen. Some...

On30 Road Engine Concept and Restrictions

Restrictions There are what I called above 'restrictions' on the design of these locomotives. Overall we have the maximum and minimum widths, lengths and heights. These numbers are NOT pulled randomly out of where the "sun don't shine" - but are taken from the restrictions placed on us by things like the mechanism we are...
