Hi all, I've had family issues which have settled slightly enabling me to get back to this.

As per excellent instructions offered by people here, I've purchased some working movements (mostly 2824 chinese clones) but first I got to grips with my Weishi timegrapher.

I aqcuired recently a Seiko 6105 copy (as worn by Captain Willard in Apocalypse Now) and it uses a NH35A movement. As it was recently purchased, I didn't feel the need to service it, but do some regulation

It started out as 2.5 beat error and was presently surprised when I accidentally got the results shown in photo. This watch is sold by Steeldive and I don't try to pass it off as original in any shape or form, just enjoy wearing it.

It's unusually comfortable to wear, I think because the case is chamfered to a rounded form on the edges. I really didn't expect to get the BE down to 0.1.

Maybe it'll stray, but not bad for a start!

My son is about to go to California on a post-doc appointment in UC Davis near Sacramento and I'd been promising him to regulate his watch pictured with its 7S36 movement.

Whilst I didn't get the results on my Steeldive, I did manage to get the BE down to about 0.4 which will be good enough for him.

This was his first mechanical watch, so hoping he moves on in the same vein if he ever comes back to UK.

      Boley lathe motor silly question.

      By eccentric59 · Posted

      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.

      Deciphering mainspring specifications…

      By Zendoc · Posted

      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

      We already have a Facebook group run by Mark , so this is a bit moot. Search for “Watch repair lessons” group.   Tom

      Rolex 3130/3135 Automatic winding issue

      By Roll1ex · Posted

      @dibs1 Hopefully you see this and post an update. @Knebo Would you happen to know what is the end-shake tolerance for a cal 15xx rotor or is there such a metric? Also, is there a specified height of the rotor?   I got the watch serviced which addressed the rotor grinding against the base plate and case back (i have checked by moving the watch in a circular motion to spin the rotor and have tested it dial up and down) however whenever the watch is shaken lightly the rotor touches the caseback and makes a ding. What is unusual is that is only happens when the rotor is resting at the 9'o clock position. The axle was replaced and reading around it seems that  spring clip, jewel and axel are the three parts that individually or together are causing this issue.

      Yes, barrel size.  A 11mm spring will push out into a 11mm barrel, no need to go 0.5mm smaller.
