I have a long chop that has been raked to 45*. There is no offset in my trees. Currently the trail is over 12" and the wheel flop is quite pronounced. Here's a crappy pic:

Following your build rules and diagrams I used DraftSight to re-design the rockers. My current front wheel is a 3.00/18 Pirelli MT66. For the CAD, I set the rim diameter at 18" and set the tire sidewall at 90mm.
I set my trail at 0.125" and applied the 90* rule. I set the spring leg hole at half the angle of rake from a horizontal zero...i.e. my rake is 45* so i moved off horizontal 22.5*.
The points are merely hole centers and are not yet scaled for true axle or leg diameters. I would appreciate the board's review, critique, suggestions, etc. Thanks!
