Escape wheel stops the mainspring barrel


Recommended Posts

Hello everyone, I am new to this forum and this is my first post. I bought several old non-working watches to learn watchmaking. Now, I am stuck at the first watch. The watch is a very old Ricoh mechanical. 

 

The movement interacts well with the train wheels and barrels. However, whenever I put the escape wheel, the mainspring barrel gets stuck and so does the whole movement. Without the escape wheel, all the train wheels engage and turns freely.

Any help would be appreciated.

Thanks.

Common faults of this issue are,

 Zero end shake on escape pivot.

Badly bent pivot, thats providing there are two pivots present.

Broken jewel to escape arbour.

Damaged pinion of escape arbour.

Escape wheel rubbing .

I don't pin much chance that picture of the movement shows us the above.

 Rgds

I stopped working on that movement. Instead I started working on a Seiko 6309a and thankfully that movement is running. The tip of the escape wheel was already broken in the Ricoh movement. So, it was dangling around and when it engaged it sat around the center wheel thus stopping the mainspring barrel...

Can I even repair that damaged escape wheel? I think I have to replace it and depending on where I live, it is near impossible to source replacement parts without exceeding the value of the watch. 

On the other hand, as someone new to watch repairs, I find it extremely difficult to do. I spend hours and hours to nibble certain parts just so it would hopefully fit.

I already had huge admiration for watch repairers and now after servicing few watches myself, I respect them even more. 

I thought it was fun but I actually stressed myself out a little bit. 😅

    • I went with 8.90£ because 12th century Italian mathematicians are always excellent topics to bring up when trying to get your guests to go home. 
    • As a beginner, I’ve found this forum invaluable. I doubt I would’ve persevered without its support. I’ve had the confidence to attempt things that seemed to me impossible only because I knew there were patient and giving folks gathered around this watering hole, available to share their skill.    I would very much like to know where to go if this one dries up and everyone needs to decamp.  There’s something special about the folks gathered in this group.  How to keep in touch?  
    • After a 3-week work fiasco that took up 137% of my time, I was finally able to get back to restoring a G. Boley 8mm lathe I picked up on eBay. I still need to do a bit of polishing on the tailstock but it works very nicely. Before and after pictures below. In any case, when I was reassembling the motor I wasn't quite sure which side the pully attached to, or if it matters. My question is ... does it matter? The listing photo below shows it the reverse of how I have it now, but it seemed that the cord and the reversing lever(s) should be on the right away from the belt.   
    • Thanks Richard.  That’s clear.   So - another question - how much latitude is there in barrel and spring sizing? Say I have have measured the ID of my barrel to be 9mm and (all other mainspring specs being equal), the closest match I can find for a replacement mainspring is listed with an 8.5mm barrel size, is it acceptable to fit the smaller spring in to the slightly larger barrel without compromising anything functionally?  I’m in this situation now with an AS 1686 which has a 9mm barrel, but the closest replacement I can find has an 8.5mm diameter listed in its specs.  I can find an alternative 9mm spring, but would have to accept a different thickness.  I’m unsure how much wriggle room is acceptable, or whether in mainspring sizing, there’s a priority - ie thickness over barrel size etc. Thanks again for any info.  Cheers, John
