Edison single spring motor

[squeeker7]

The spring on the B-19 I am restoring runs good but has one big clunk due to the sticky spring syndrom (SSS). Has anyone removed the access screw on the side of the spring barrel and tried cleaning out and relubing the spring via this method? Was it successful? Sure seems like its worth a try considering the alteernative.

OOOps - didn't see Deb's post asking the same thing. Sorry about that

You'll find it extremely difficult to clean the spring via the small screw hole, BUT Edison DD & Amberola grease seldom solidifies unless it's been exposed to extreme heat, unlike the graphite grease that Victor/HMV & other companies used. It does dry out a little, but nowhere near as much as any of the others I've come across.
Before pulling the spring out for a proper clean, I would try adding 2-3 teaspoons of vasoline to the spring barrel & existing grease (which is apparently vasoline & graphite flakes).
That should be enough to mix with the original lube & return it back to it's original consistancy (or pretty close to it).
I've only done this once (feeling lazy ) about 8 or 9 years ago, and I haven't heard it bump once since, although it's not a machine I use more than a few times a year.
To be honest I cant remember what I used on that one to get the grease/vaso in the barrel, but I have since topped up a few of my other Edisons, by using a large syringe that comes with cartridge refill ink that I buy. I just pull out the plunger, load it with vasoline, replace the plunger and inject it in the hole with the spring fully wound. Then I let it run down (after replacing the screw) & rewind it a couple times to mix everything together and spread it evenly over the spring.
I'd certainly give this a try first, and if you find the original lube is too far gone & the spring still bumps, all you've lost is a little bit of vasoline.

Ok thanks, I'll give this a whirl and see what happens.
