    Should our cutting bits be heat-treated? Or left as-is?

    Glen, That's just about as I expected. I probably didn't even need to ask, since my own experience has given me no problems cutting brass OR steel from standard HSS blanks (I use Cleveland blanks as well). I suppose I just wondered what the collective thinks about the matter. By the way, I use...

    Should our cutting bits be heat-treated? Or left as-is?

    Something I've been wondering about for some time. Regarding the gravers and sliderest cutters we use at the watchmaker's lathe, have any of you guys ever bothered to heat-treat them? Assuming we start with high-speed steel, it seems obvious to me that hardening the cutting edges is unnecessary...

    Making a Delrin Drawbar Knob for a WW Lathe

    Schatznut, I read your comment over a week ago, and I keep thinking how true it is! That's a great way to describe Delrin - it's "the brass of the plastics world". In the world of brass, alloy 360 is made with a small percentage of lead to make it so machinable. I'll live if I never find out...

    Stuck on dismantling Rivett headstock

    Rick, I'm a user of Rivett lathes also. There's a Rivett expert who shared a Word document with me describing step-by-step how to disassemble, reassemble & adjust the Rivett headstock. Send me a private message and I'll reply with the document as an attachment. By the way, don't use PB blaster...

    Finding a chapter near you

    Thank you, Steven. The problem must be on my end. Whenever I click on that link, I just get an error message of some sort. Can you supply a contact email, please?

    Finding a chapter near you

    Is the chapter 63 for Wichita, Kansas still in existence? The website seems to be completely taken down. Can anyone shed some light, or direct me to an email address for someone who can help me get an answer? Thanks in advance.

    Help understanding a depthing tool

    Jerry, Aaahhhh... it's just a pen, and not a camera! Alright, everything in your post is suddenly "pulled into focus"... it was merely a way to indicate scale. Thank you for clarifying. My gosh, that certainly is a tiny boring bar.

    Watchmaker lathe collet quality and brands

    Very interesting thread. I use a Rivett watchmaker's lathe and I've acquired a full set of collets, and lots of spares. For the sake of settling on the best collets I have, I've evaluated each and every collet using a methodology similar to what Jerry Kieffer outlined above, with a couple of...

    Help understanding a depthing tool

    Pardon me for butting in... Jerry, what is the object with the green grip in your center picture? It appears to be a ballpoint pen, but of course it can't be. The tip shown in the third picture seems to be a lens - so is it a camera? If so, where did you obtain such a marvelous tool?

    Ladies' watch built into a ladies' ring

    Thank you Dr. Jon, I didn't know Bucherer was a chain of watch shops... I thought they were a maker of watches. Any information is good to know, and I appreciate your input.

    Ladies' watch built into a ladies' ring

    I have a very interesting piece - it's a watch built into a ladies' ring, with a beautiful cameo on the top of the ring as a hinged cover for the watch. The watch's face is marked Bucherer, which appears to be a Swiss maker. I found it in my mother's jewelry case after she passed, but there's...

    Grinding cutting tools from round HSS stock: advice sought

    Dr. Jon, how do you sharpen your carbide blanks? Do you have a diamond wheel? I rarely find a use for carbide cutters, but they're nice when needed.

    Grinding cutting tools from round HSS stock: advice sought

    Thanks for all the input, guys. In the end I decided to have an index block made at a local machine shop. I thought it would be simpler and more effective than a collet-holding block. When I get it back from the shop I'll post some pictures here. Again, thanks to all of you for chiming in.

    Grinding cutting tools from round HSS stock: advice sought

    Here are some pics of my compound sliderest. A couple of the pics include a stubby pencil for some size reference. Lastly, I removed the Rivett toolholder so you can see the three slits enabling the clamping pressure onto the cutting too. It's a brilliant design, but it presents the grinding...
