Re: vibration at 65 mph?

[Doug J <63sprtfury@xxxxxxxxx>]

Yup,, used 'em.  Dangerous when it came off the wheel, but no better
balance can be had.
We used to do the rear wheels on non posi cars at 45 mph (90 real
time).  Learned to do that by laying my head on the quarter panel
above the wheel...  When yer head stopped vibrating,,, the wheel was
balanced.!!!    My   boss said I was the best bubble balancer in
3 states,,,,,,,  I said he was the best spin balancer in the U.S.
He's long since gone,,, but I stand by the statement. !!!
