Today, I completed the Y. Eventually, I'll replace the temporary plywood roadbed with foam roadbed. I used plywood under the flex track to give the track screws more strength while forming the curves.
In this photo, the left leg of the Y is sectional track.
In this photo, I formed the flex track (left Leg) by eye.
Here, I formed the flex track using the SCARM 1:1 print. I just discovered this SCARM feature on the weekend.
My home made chop saw for cutting track.
