After building the frame in Blender3d, I have a real good idea of how it needs to look. However, my 3d rendering is not to scale. So I have to do a 2d side view of the frame to determine it’s proper dimensions.
For the people that like “plans”, this is about as close as I get. If the dimensions aren’t perfect, I can make up for it by moving the bogies (and roller wheels) up or down until everything is about the right shape.
So, I used my drawing from TrackMath, and modified it to figure out the frames dimensions. I did make one slight change from the 3d model, which was having a small flat part in the back, instead of a straight 45-degrees to the top rail.
The frame is of course, the thick blue line. That’s pretty much that. I know, nothing ground-breaking here, but a necessary step nevertheless. And most importantly.. it means I can begin the frame construction soon!
I’m going to use square tube, probably like 3/4″ OD. I will decide for sure once I feel the actual material, and get an idea of weight.
I also need to decide exactly how wide to make the frame. I can’t think of a good way to do that, other than pretty much winging it. Total width will be around 3ft, but this frame will fit inside the tracks, so about 2ft wide… I guess.
