Wanting to do a bearing replacement on a nice Boley Leinen ww-83 I picked up recently, nicklesilver gave me the idea of using angular contact bearings instead of deep groove bearings. AC's need a way of preloading them and need to be installed adjacent to one another or with precision spacers between them. I splurged for the expensive p4's and while they are the right diameters, they're thicker than the OEM deep groove bearing so I had to make both spacers. I bought universal matches AC's so if I ground the spacers exactly the same, it should be the right preload. So far so good, but it did seem like the preload was almost a tad heavy. The groove in the outer spacer is for a felt oil wick Drive. As nice as this lathe is, the drive was terrible. Basically a universal motor with a great big rheostat, yuck. I had a consew motor (variable speed servo) that I moved from below the bench to the back and connecting it to a jack shaft bolted to the bench. I took the brushes out of the motor so its also just a jackshaft, er, flywheel. I made a control box so I can switch between rheostat control of the motor and foot control - you want both for different ops. Its actually a better arrangement as the Consew is mounted on an adjacent bench so zero vibration reaches the lathe. I'm stuck with the hole in the bench....have to 3d print some tool tray thing and make it look intentional. I've 1/2 a dozen watchmakers lathes, each one has something unique, so the idea is they're out of the way in a cupboard but can be placed in front of the jackshaft and set to running in seconds....keeps the bench less crowded and I only have to have one drive. This one has the rare thread cutting attachment, which even has tumbler! To use it though, I'll have to rig up a toggle reverse switch (the consew is a bit of a pita to reverse) I replaced the bearings in the motor and counter shafts as well, stripped and repainted and installed the new p4 spindle bearings. Not shown is a full set of change gears, milling spindle and second 3 way slide rest. I think I'm having too much fun big headstock.....little headstock

Quick change for evening snack and to cheer myself up that a watch I was winning on didn't reach reserve.

Although still expensive, I thought this “simpler” perpetual calandar movement idea was brillant. I love to see complex and over-complicated ideas simplified. Thinking outside of the box, no following the crowd, being unique and opening the door of complicated engineering to it’s simpler form. This movement could sale more than Rolex if it was in a more resonnable price point.

Its not a fake.

Took your example and made me a balance tack as well. With an extra hole for a k&d tool that was hanging around without a base.

Thanks. Yes there are some similarities - here's an AS 1130 inside a '50s Fleurier Watch.

As promised, a yin and yang of Janatas. Today's "Watch of Today" bears an uncanny resemblance to the "Watch of Yesterday". The strap it came with was a very disappointing cheapest of the cheap Chinese knock off Chinesium "steel" straps, held on with two oversized pins that I had to cut in order to remove. I didn't have a white strap with black stitching for the full dualist effect, but if I spot one, I'll grab it. Meantime it graces a simple black leather one.

At 2:10 the guy picks up a bridge with bare hands, drops it, hits the holder on the 2nd try... I felt reassured about my technique LoL.

Hi I have attached the pics of the amplifier setup I dont know if the radioshack telephone amplifier is available in the UK any more but there must be others that will work, With the loss of Tandy and Maplins these sort of bits are hard to come by, Might get them off the net .

I was under the impression he'd emigrated.

Let see if we can get Mark lovic to service them, wouldn,t hurt to ask. I think he just may want to make a video( lesson) out of it. Just a thought.
