Reply to "Track Plan Design - Part Two"

I've started to work on the math of turntable and roundhouse design.  This is the diagram that I put together.  If you have the with of the front, rear, and side walls you can compute the distance from the TT center and the arc width of the stall.  If you want to design your own given your constraints on space the equations can give you the other data that you need. 

θ_s - arc angle of the roundhouse stall

w_f - width of from wall

w_r  - width of the rear wall

l_s - length of the side wall

d_s - depth of the stall

r_r - distance from TT center to rear wall

r_f - distance from TT center to front wall

r_RH - distance from TT center to rear corner of RH

PS.  I'll edit the post with the equations and any examples that I can find.
