Boley lathe motor silly question.

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.

Wow what a difference. As long as you are happy with the set up and it works for you it makes no odds. The belt is in line with the pulleys so no problem there.  

No questions are silly on this site.

Hi. Bit of a difference now, as OldHippy said as long as the belt is in line with the pulley it’s ok.  With the reversing lever on the right end it keeps your fingers away from the pulley / belt area.

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

Only 137% !  sounds like you're not putting enough effort in 😆.  I would think of it like cogs on pushbike.  Fastest speed to the spindle would be largest pulley wheel on the drive and smallest pulley wheel on the driven. If the motor was into a sliding bed you would have 3x4 ? Speeds.

      Smiths rim wind and set

      By transporter · Posted

      Ok, as per pictures I have a smiths rim set and wind on the bench, swimming in oil but all sorted. The fault I have is the mainspring bridle has lost its tab/notch/hook, like a hebdomas pocket watch the mainspring is fitted to a bridal in the barrel which slides around on full wind onto 4 notches in the barrel wall, thus stopping damage to the mainspring by over enthusiastic winding. So my questiion is this, what is the best way to create another hook in the bridal, my thoughts are along the same lines as making a new hole in the mainspring end, annealing etc, but what and how to make the hook?? I have a pair of barrel hook pliers that work great in soft brass but won’t even scratch the bridal, what I don’t want to do is whack a hole into it and not have a hook. the pictures are of the bridal ( broken) and a hebdomas ( complete ) incase you are wondering what I’m on about. And a few of the serivce. Thanks for any advise.

      Decided to give the case and bracelet a good cleaning and my first shot at polishing/brushing. Went with the Cape Cod polishing cloth and gray scotch brite method.  Before First; Then After; Then comparing to some original links from when the watch was new to now.

      It's either bent or hung up on something or both. The hexane won't hurt it, and hanging from a balance tack indefinitely won't hurt it.   If the spring is glued to the stud there's a chance that the glue was softened and the outer coil stuck to the stud. Haven't seen that happen, but I suppose it could. Don't know if hexane affects the glue used either.

      Hello all. some help required here from the community please. I serviced this movement, which was running reasonably well, but the balance spring which was running healthily before I started, after cleaning in hexane for 30 secs, is all bunched up at the stud. I did store the balalance on a tack thereafter for a day.   could the spring be strained under gravity? I demagnetised of course, and the balance is squeaky clean. some help would be much appreciated. Thanks, Tony G
