Great video. I'm building a roller coaster myself and I keep running into the problem of the track sagging to the sides with only one post in the center of the ties. How did you fix this because I noticed you only have one as well.
I'm not quite following you. What is your track gauge? Are your ties 2X4 wood? Is the wood sagging? How heavy is your rider, and what is your force, in g's?
For 1-1/2 inch PVC, I take a ~7 inch piece of 1-1/4 PVC, cut a 1/2 inch slit in it longitudinally, compress it to slide into 1-1/2 inch rails, then secure with short countersunk screws.

Hi, gregg! Would you mind sharing the dimensions in lenght of the 3 parts (purple, blue, red) at 7:39?.
Those sections of track are about 10 feet long, which is the nominal length of PVC pipes. I think this track gauge was around 16.5 inches.
Excelent videos Greg. A question please... How do you bend tubes to get the radius of the track?
How do you connect the PVC pipes
