Personally, I think your posts are fine. Maybe if you create a separate one one for your truck vs. inside the locomotive, it might make things a bit more organized & easier to search on later in time. If the truck or locomotive gets more followup views or questions, then you be the judge of what more you'd like to contribute on that theme. The admins have also set up a CNC area, so if you were ever inclined to talk about your CNC equipment or workflow, examples etc. that would be a good theme spot too. You have a lot of interesting projects on the go, so its all good!
