FINALLY a new video! A more detailed overview of building the tailstock turret for the watchmakers lathe.
Remember that tiny quick change toolpost I made for the Sincere watchmakers lathe about 5 years ago? I’ve had several requests, over the years, for plans/drawings, and after the most recent request I decided to do it. I’m going to start making project plans and drawings available through my Patreon page from time to time, and the drawings for the miniature QCTP are now available there: https://www.patreon.com/posts/drawings-for-now-21190714
This is my prototype watch movement holder that I designed a few months ago then finally got around to making. It feels solid, grips extremely well, looks great, and can accommodate very large movements when necessary (for example, I have some automotive dash clock and desk clock movements that are too large to fit commercially available holders).
Here you can see the components - the guide pins are O1 drill rod (used simply because it comes ground to a close tolerance from the supplier), the side plates are 6061 aluminum (though something like Delrin might be a better choice), the lead screw is 416 Stainless (single pointed 1/4″-28), and the jaws are also 6061 aluminum.
These last two photos show a later modification I made, to use a circlip and belleville washer instead of the compression spring. So far I’m really liking it! If you’re interested in the drawings for this tool, check out my Patreon page, at https://www.patreon.com/joyofprecision
I was of two minds, on whether to do this video but in the end I’m glad I did. I’ve already had a lot of unexpected positive feedback about it. If you’re interested in how to single point metric threads for general (non-precision) use without needing a transposing/translating (127 tooth) change gear, then this might be useful for you.
