My original slot car track was built from scratch, and was free-standing and 30" above the floor. See my pictures.
I replaced it with new model railroad benchwork construction, which is now 12" higher (42") than the old slot car track.
This seems awful high for slot cars, but I'm 6'2", so I'll have no trouble viewing the entire layout from a standing position. I don't think I could comfortably dismantle it and build it lower, since I'm partially disabled from Arthritis in Back, Knee, and Shoulder.
The 2x4 framework is lag-bolted to the studs in the wall of the building, so that would make it more troublesome for me to convert to a lower bench.
What do you think...should I proceed and begin removing the 0-scale 2-Rail track?
