Hi All, 

I did a quick search but didn't see any golden nuggets....my 1972 car's Flasher/Hi-Lo beam switch has disintegrated ...below 2 others I have dismantled...all have same failure mode despite there being 2 different internal designs. The plastic fulcrum piece which has the (metal) stalk pinned-in is cracking-up...I tried cleaning and araldite....but it's not lasting...any solutions out there??


Early(?) Type


Later(?) Design


Same failure mode....

Believe lots of these were damaged by folks getting into the car.  Be careful if you are wearing a jacket or coat with pockets.


Ask Grice Mulligan if he has any column switches to sell.  New ones may still be available.

FYI, all the low/high/flasher stalks on roundies (at least 2002s) are the same; only the knobs are different.  Pre modell 71s have bakelite jellybeans, later cars have flattened cones.  Gives you a wider range of years to search for. 


Coat sleeves are death on those stalks.  My wife did that on our '69 when it was less than a year old--even then the switches were expensive!


Too bad some clever soul can't 3D print the part from a good sturdy nylon plastic...

I changed the title: Following Mike's suggestion - this would be a great opportunity for a small 3D printed piece from a tough plastic! 

I think its not super-precise on dimensions or surface finish, the stalk socket and bearing can be push-in or even glue-in.


Is anyone skilled in the art of translating a broken part into a suitable 3D artwork??

I agree, they get weaker with age ;)  


I also suspect that the plastic wasn't grease- compatible, so that weakens them 

further.  I have taken apart at least one that was pretty much goo.


I wonder if a nylon print would be strong enough...
