[Spridgets] Ignition Sw.

[Vernon Olson]

Does anyone have a good way of tightening the electrical posts on
the Ignition Sw?   On two different Sws. I have had one of the posts
get floppy and make poor contact.  I used a punch to flatten the rivet on
one, but got a little carried away and cracked the phenolic plate.  I am
wondering if it is possible to solder  the rivet and post together, but
am guessing I would need to use acid flux  which is hard to totally remove.
Any Clever solutions?
