Watch Makes Scrapping Sound Crown Up

[jdrichard]

I just finished repairing an old 7J Waltham for a friend. Got it going well face up, face down, crown down: but scraping sound and slows down and sometimes stops crown up. Is this the impulse jewel closed to the opening back of the palate fork or could it be the hair spring. This is a very cheap watch so I don’t want to spend to much more time. Already replaced the mainspring and cleaned it up significantly. And I made a bow out of a coat hanger wire and a lot of pounding.

 

Help.

Nice job on the bow. I'll have to go after some of mine some day.

Do you have one of those fancy bow end cutters?

Do you get the sound only when cased or is it ok  out of the case.

No I do not. All built by hand. Tough job.

Not sure, will need to remove it from the case. The balance looks good and it runs really well in all positions except pennant/crown up

Have you examined staff pivot side shake?

If you will, Let us hear the scrapping sound.

Will need to do this on the weekend, out on business.

I too, suspect the roller and guard pin rubing, since excess side shake reduces the distance between the two in dial up position.

I think you may be correct.

Back home, will check this out tomorrow. Bugs me as it took a lot of work to get this one working again...needs to fully work.

Old piece, general wear out.

May need to rub in a new jewel.

And this is the reason I stopped doing favours for people and their old watches, I had one not so long ago that I eventually spent about 6 weeks working on it, spent about £100 trying to source parts ( old cylinder movement ) and in the end only got it semi working, very frustrating and added pressure to ones life. 

But nice job done there mate, I’ll jump on the side shake train of thought and new jewel required.

Turned out the impulse jewel shellac was completely gone on the roller table. Now works, however, can't get it to run fast enough Ahhhhhhhhhh!
