Amazingly, this has stayed on topic for lathe cutters and accessories
Jerry, I think you should have used a steam powered overhead shaft to blend in better in that video, but nice work --even with the chips. I've appreciated the value of the Sherline since you rotated the headstock to demo cutting tapered tooling a while back. I'm nostalgic about old tools, but I agree the old stuff is technically obsolete.
In '91, I got to visit Audemars Piguet in Switzerland, and learned they make a lot more than expensive watches. I saw dozens of giant green German machines with oil flying everywhere doing gazillions of sequential robotic operations. I think they were making micro-parts for jet engines to help pay their bills. It's only gotten better since then. I'm just an old guy repivoting old clocks with old stuff, but it keeps me out of trouble.
I'm in Italy for what I'm calling a "lasagna lockdown." So, I'm lucky to have found a matching head/tailstock from a BHI member who was getting rid of stuff, and just trying to make it work to finish up the DLC --someday-- and fool around. The Lorch offset drilling runner has a taper I've never used, but it probably works okay. But, even if my work never left the chuck, I won't be able to drill like that photo until I make a better holder for the bits, as most are smooth shank today. And, a lever will have to work, as I'm not making any money.
Thanks for the MSC tool reference! Graham, where do you shop in the UK, if I may ask? Eternal and RDG don't seem to have bits like this. And, in the pictures, that "slackenator" spring is 100% genius. I will copy it going forward. Can the same idea work for a cross slide? And, does that disk behind the drill chuck work like a "backplate" to take fine runout out of a self-centering chuck on larger equipment? I can't seem to find much on their site (or did you make it?)
Thanks again for all the comments.
