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...........

Does anyone know what type of plastic the cam is made of?

"Not heat resistant enough".

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.
