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").

      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?

      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.
