1. Tire Balancer (See Figure 1.)
A useful tire balancing fixture can be built as follows:
A. Chamfer top edges of -3 sides, leaving 1/16 inch flat on top of the inboard edge. Rivet -2 tee’s to -3
sides using AN 470-AD5 rivets, with 2 inch spacing, and using AN 426-AD5 rivets ( 2 inch center to
center ) to secure -2 tee’s to -1 base. If tee extrusion is unavailable, heavy angle extrusion could be
used. -3 sides must be vertical.
B. The -4 axle must slide through the -8 pipe, the -5 nuts are made by reaming the existing threads in
the AN 365-624 nuts with an R drill, then tapping them with a 1/8-27 pipe tap.
C. The -6 spacers were made from 1/2 inch aluminum tubing, the two lengths of spacers are suitable
for balancing most any aircraft wheel.
D. The -7 bushings may be made from one inch phenolic or aluminum using a 1-1/2 inch hole saw to
cut out the smaller bushing and a 1-3/4 hole saw to cut out the larger. By inserting a 1/4 inch long
threaded bolt through the pilot hole and securing with a washer and nut, a drill press and file may
be used to make the off-set on the bushing. The turned-down part should just slide inside the
bearing race and then ream the pilot hole to slide over the -8 pipe threads.
E. The -8 pipe was made from a piece of 1/8 inch black pipe and threaded with a 1/8-27 pipe die, this
will be thread 3 inches in from each end of the pipe.
