Determined convergence point in front of aircraft for a toe-in angle of 0.7 degrees. With a 68" wheelbase gives a centerline to inside axle dimension of 34". Tan 0.7 = 34/X, X = 2,783 inches or 232 feet. The prelim calculation indicates that the slight toe in will need additional work to arrange in a 40 foot hangar.
Worked up complimentary methods to set the wheel alignment with axles other than Sonex.
