Open Spring Barrel

I've search the forums and found ways to open the spring barrel, but I can seem to figure out mine. I don't see a retaining clip.

You fail to mention what brand you're dealing with. It looks like Victor to me, and I've wrestled with a couple of these myself. Ultimately, I cleaned the circular plate that sits within the barrel, attached a strong magnet to it, and lightly tapped around the perimeter of the barrel, which gradually worked it away from the circular plate.

There may be a better way to do this, but this method works.

Good luck - -

Yes , I've worked on several of this type of spring barrel over the years -- usually on HMV motors . As George P mentioned , if you tap lightly around the barrel where the plate fits , at same time holding the barrel in a position with the plate facing downwards , it should fall out -- that is the correct method for removal of the plate. I would just add that I always use a small wooden headed mallet for this -- equally a rubber or rawhide head should work fine -- avoid using a metal hammer head as it may leave marks on the barrel or even distend the shape of the barrel slightly which would then make for problems upon re-assembly. Good luck !

Interesting - - I have resorted to using a strong magnet to hold the plate facing upwards, while tapping off the edge of the spring barrel downwards... It shows there's more than one way to skin a cat.

Excellent advice on choice of hammer. I use a hard resin mallet for this kind of thing. or wrapping a metal hammer's head in a single layer of old sock will work in a pinch.

Dulcetto's method, (same as mine), relies on the inner coils of the spring to "bump" the cover plate each time you whack the barrel with the mallet. Works great!

Makes sense - and it probably works better than my method. Thanks!

Thanks for all the tips. Do I have to worry about the spring falling out if I hold it upside down?

It's doubtful. The mainsprings are reasonably wide and long, so they don't uncoil unless there's lots of clearance. The original grease is also very likely pretty gummy, so as not to let the coils lower very much. Your hands are right there to push it back into the barrel if necessary. Once you do a couple of these you'll see that they don't exactly explode when you take them apart.

Well, a few taps and it popped right off. Good news is the spring isn't broken, but the nubbin that is supposed to catch in the hole doesn't seem to want to grab. I'm thinking the end of the spring has flattened out? Is it a just a matter of bending the end so it grabs easier? Also, think I need to regrease? There is definately some harding of the old grease.
