I laugh every time I see this guy's work. It would take me longer to find the "darn" die than it takes this guy to finish..

Joe, stop looking at stuff like that, it will cause you to spend way more time in your shop than you do already. I saw a live demo on that once, it was very cool to watch and very difficult to do at my shop.
 
All of Hakase's pens are individually hand-made to order. You go to the shop in Japan, and they have you fill out some forms to analyze your handwriting style, then tailor a pen and nib to suit you. Very long waiting list, too. :-)
 
He makes it look easy. I hand chase threads but haven't tried it on a pen, yet. I cheat though. I use a tool rest. Guess I have my work cut out for me.
 
guys he's just using tools specialized for this.

The "lathe" he is using has two settings, one just spins at one fixed point like ours, but the other setting spirals in and out, forward and reverse. The Tool rest he is using has a large base that is placed on the table base the lathe is attached to, the hand just holding it steady. Given what he's working on catches aren't a big concern.

This is a prime example of letting the tools do the job they are made for. I'm not knocking his abilities, just saying that any of us could do the same with the same tools. Also, I didn't see him cut the internal threads on that cap, now that's more challenging.

it's much more than that:
I don't recall seeing those tools on HF!!!! half the challenge -scratch that- 90% of the challenge is coming up with tool, jigs and set ups that fit your project.
the whole idea of sitting while facing the chuck is novel, and he obviously adjusts his own chisel and tap.

the fact that he doesn't use any gauge, micrometer or anything ,attest to his craftmanship.

yes, me and you could do the same thing given enough time, but that's like saying "if I'd diet and exercise properly I'd be skinny and fit"
 
Not sure those are quad start threads (a different thread starting every 90 degrees) but his thread chasing is outstanding!!!

I suspect that was not one of his early attempts --- love to see skill and knowledge come to focus.

AAW has some video of bowl turners from Japan at a symposium a few years ago -- way different way to come at the wood and a nice outcome.

I don't have time to go searching right now, but this video was posted before and a link to the tooling was even provided in the thread if I recall correctly. The lathe mechanism wasn't cheap but was available for sale. Remember, that just because something isn't widely available here, doesn't mean its not available elsewhere.
 
The site that showed the tools and their prices was indicating what Hakase had just paid for the *new* lathe, an upgraded custom-made machine to replace the much older custom-made one in the video, along with new custom-made tooling.

The spindle is still driven by a motor for turning, and by a treadle-driven rope wrapped around the spindle for threading. If you pay close attention to the reciprocating motion, the stroke is too long for a single-start thread of that pitch; a four-start thread makes more sense. :-)

I wonder how consistent he is; will the cap from one pen fit the barrel of another?
