I have another thread going about an upgrade to Shepherd Speedway but thought this new post would be the best way to get feedback about options for the turns.
It looks like the track will be CNC routed using programs written by Brad Bowman. As the designs moves forward I'm debating whether to go with slightly banked turns for the oval, around 10 degrees, or just tilt the track upwards at each end to create slanted turns of the same degree. I've done the math for cutting the corner sections at less than 180 degrees so they can be banked while pulling the attached straight sections inward to be parallel, but am also considering slanting the turns as Harry did on the build thread he posted about his oval.
Slanting will be easier to do but will it provide the same effect as banking - allow cars to take the turns at slightly higher speeds without as much tail sliding? The current version of my oval is a flat track with a hardboard surface and some of my cars are very hard to control in the corners even at reduced voltage. The new track will use mdf but I think slightly banked or slanted turns will be valuable too.
For those who have built or raced on home track ovals with banked and/or slanted turns what are your thoughts?
