egg timer thingy cleaning
« on: May 15, 2018, 08:54:45 AM »
This little gem is a highly coveted part in old arcade machines.
Background: It was used in everything from pinball machines, to love testers.
Anything that had a timed game, needed one of these.
History: These dittys appear to have been made from egg timers, with the hammer turned around, and a fiber push disk applied.
So when it was wound, the hammer pushed a switch closed.
When the time was up, the hammer fell, and opened the switch.
Problem: these things are always gummed up, and you cannot dis assemble them to clean the works.
Big problem in the arcade industry. And no alternative!
Solution: Marvel mystery oil.
Soak it in the oil bath for a few days, work it around, a bunch of times, and working!
Nice recovery.
Only glitch, I don't know how to rinse the oil off...not that i need to, but would be nicer.

Buy a can of automotive spray brake cleaner, it will remove the oil residue.
