cocktail shaker restoration
« on: December 28, 2010, 02:17:42 AM »
The front cocktail shakers that I have for my 69 are missing the lower mounting legs due to rust. Has anyone seen replacement mounts out there?

I have seen replacement units. I have never seen replacement parts...if such exists, they would have to be welded.
These shakers contain hydraulic fluid inside..and I am not sure what welding heat will do to the inside.
I would be concerned about heating up a closed unit ..especially to the temperatures that are needed for welding.
I would definitely open the top and drain them, and keep them open while welding.

(They are technically called Ballasts..I assume you have a convertible?)

I saw a listing on e-bay the other day for two front units both had rotted legs, but he had metal templates that needed to be bent and welded that went with them. If I could locate a set of good ones I could template the legs and fabricate replacements. Its amazing how only the lower leg rotted off and the rest looks great. Thanks for the reply.

I'm redoing my car this winter and front and rear balasts are out of the car. What do you need exactly for a template?
Measurements, picture?
Let me know.

(BTW, mine is a '68..I am assuming they would be the same...????)

Sorry, 68s are different from 69s due to fender and qtr differences.

Actually, they're called "Dampener Assy".

To dampen the torsional vibrations in the convertible body structure (commonly called "cowl shake") that result from lack of a roof structure. Corvair convertibles had them too.

Yes. They contain a cast iron weight on a shaft with springs on both sides, and are filled with ATF; the spring rate and orifices in the iron weight are "tuned" to dampen specific vibration frequencies, depending on the model and damper location.
