Well all you kids had those fancy new toys. Strobes for balancing weren't always around. The Seventies? Disco Strobes? Travolta style finger pointing?

BuzzLOL . My balancer cost $5.95... what do those newfangled contraptions cost? ... And, look, they're so new, they even have power cords... as in... electricity...

boothboy Those are not spin balancers. Those are bubble balancers. This is a spin balancer. They would spin the tire up to road speed 65mph. You'd find bubble balancers at tire shops. You could get a better balance with a spin balancer.

Lord help me! I've got nothing but kids to teach!!

MARTINSR Never heard of that BB. My brother has an old balancer like this one with chrome mouldings down the sides.

boothboy Well It's not a hand sign . The placement of the fingers is a tool.
In the olden days a front end mechanic usually was the person who, along with the normal front end repair, did all the spin balances. The old trick that I have seen many mechanics do was to form their hands as I pictured , laid the pinky finger on the front bumper and by watching their index finger stop vibrating know when the balance was correct. A out of balance tire spinning on a old Hunter Balancer would shake the front bumper so violently you'd think it was going to jump off the car.
Now a days nobody spins up a tire to any great speed. The front end repair man usually doesn't balance tires anymore, the tire guy does.

Vibrating fingers, a lost tool.

Vibration idling or on the road ?

On the road would be tire balance or out of round. Idling could be any number of things that cause a miss-fire.

The hand sign must be a west coast thing because I have no clue what that position would indicate.

I will say this, if I have to explain the answer you'll say " Yeah I can see that"
