This 1920,s gravity clock that has a really simple movement required a lot of work to restore. Every bushing had to be changed with some of the bushes I had to custom make. The escape was very badly worn & the escape wheel was misshapen with many teeth out of true and all of the teeth had wear. I straighten the obvious teeth with small smooth nose pliers and every tooth was treated to a smoothing with a fine escapement file. Then see below I had to check all teeth where true, the wheel was true & all teeth where exactly the same height. See pics & short vid.

Well done clockboy seeing the lathe brings back found memory's for me. I agree with you I don't like the clock. With some of the bushes I had to custom make. I always did that those ready made ones were never a good fit and quite soft brass.

Yes it is a novelty clock & I think ugly,but the customer loves it!!!

All of the bushes that I made were made on my lathe ("Star").

      Good exploded movement posters...

      By JeremyLaurenson · Posted

      I suppose this fits "best" in this forum 😃 Im looking for some wall 'art' that doubles as a reference. Specifically Id like to find an ETA 28xx or Sellita exploded movement view. 2824/2836 would be ideal. Have any of you seen/found such a thing - there seem to be a lot of these for specialized movements, and none of them ready to print or to be had as a poster. Why help is appreciated.

      Deciphering mainspring specifications…

      By praezis · Posted

      The diameter is that of the ring - afaik, will have to look it up. “Wiggle room“ doesn‘t matter as long as the spring length is in the ball park.  Essential sizes of a mainspring are thickness, width and length. Diameter is just a hint if you can push into the barrel directly or will need a winder, it is no property of the spring. Frank

      Hi @Zendoc, I guess you're like me and you don't have a mainspring winder.  I searched GR mainspring for the AS 1686 mainspring and I now understand your dilemma. The exact one is discontinued. To answer you question more directly, I see two good alternatives for you: a) GR4485 with 1.60 x .10 x 280 x 8.5 ( I guess this one is the one you found): https://www.cousinsuk.com/sku/details/mainsprings-by-list-watch-pocket/GR4485 OR b) GR4477 with 1.60 x .095 x 320 x 9. https://www.cousinsuk.com/sku/details/mainsprings-by-list-watch-pocket/gr4477   As you know, the the AS 1686 spring is supposed to be 1.60 x .10 x 300 x 9. - both of the above will fit and you'll manage to insert them from the retention ring without need for a mainspring winder (provided you know how to do it). - GR4485 will give you more power (=higher amplitude), but less power reserve (due to shorter length) than the original. - GR4477 will give you the same power reserve as the original. However, a bit less power.   Personally, I'd take GR4477 for two reasons: 1. Well, the power reserve is better. 2. With modern lubricants and modern mainspring metal alloys, you tend to get a higher amplitude anyways. You'd maybe even end up with too much amplitude (knocking) if you go with the original size and use thin synthetic oils-- see discussion here: https://www.watchrepairtalk.com/topic/10580-omega-calt17-help/#comment-248101

      Boley lathe motor silly question.

      By praezis · Posted

      Your setup is correct. The smallest diameter of one pulley must correspond with the largest of the other one, else not speed variation. Frank
