A "Somewhat" repaired Control Cam

Post by gpartin »

Hey all on a recent purchase for parts Mark VII I came across a Somewhat repair job on a control cam and just had to share it.
It looks as if the guy put some thin aluminum on the inside then built a end from bondo or a rosin type compound although he didnt make it complete as you can see......
I guess you would not be able to get either the low speeds or the higher speed as you cant go all the way around with it and when I got it the motor
would run but the dial had been turned to far and walked off...........

"Not heat resistant enough". :D

I believe it was generally referred to as "nylon". It and the rack on the way-tube both.

Perhaps "Zytel", that miracle unbreakable substance from which Magna American vintage couplers were made of. Too bad they were not 'heat tolerant' as well!:D

Zytel looks/acts a lot like a more translucent nylon cousin.

There be an interesting MVII on EB that has a stick of wood along the way tube with what appears to be 'teeth' cut into it. There be some amusing 'irrelevant' pix included in the listing also.
