Stinks that the drill broke on you, but nice recovery. Back when I ran deckels for a living I found the quill to be sub optimal for micro drilling. My solution was to run the quill all the way down to its stop and increment the table z up a little for each peck. Peck the quill down till you hit the stop, come up clear chips, move the table up however many microns, repeat. Certainly slow, but it kept my clumsy hand from over feeding the drill. Great video, I enjoyed watching along
Hello Adam! Many thanks for your kind comment, I am thrilled to find you among my viewers! Thanks for the hint with micro feeding the quill in the lower stop, that is surely something that hasn't come to my mind. I appreciate your videos very much, IMHO only very few people are out there with your skill level. Hope you are doing fine, ATB, Alex
Retired watchmaker here. It's fascinating to watch your approach vs a watchmaker's approach. For what it's worth, I would most likely cut a suitable piece of stock from a piece of annealed O1 or similar steel, clean it well, then silver solder the broken part to the stock. Drill any holes, normally by hand with a pin vise on a precision lathe. Cut away excess stock with jewelers saw or cuttoff wheels (VERY carefully). Finish with files, rough polish, separate the new part from the old. Test and final fit the part, harden and temper, then final polish. When the lever is finished, turn the pin using a handrest, polish then set the pin in the lever with a staking set. Pretty much all by hand. Of course, as much as possible is done through the microscope(s).

Drilling small holes is definitely not easy. The most impressive drilling I have seen was on a Japanese show where two teams of machinists were tasked with drilling a 0.02mm hole through the whole length of a 0.05mm piece of mechanical pencil lead which was 50mm long. The winner did it on a manual lathe. To be able to drill so deep into something so delicate was incredible.
I have made some Watch Parts by hand in the past, usually by using saws and files. It’s a lot of fun when it works but it’s a lot of hard work to get to the final product.
Certainly a different approach to that of the "traditional" watchmaker, but the only way it could be done on your huge mill! fantastic piece of work. Well done, and thanks for sharing. Retired clock/watch maker.
Only a master would think to use work-holding tooling to drill a precision hole. I was wondering how you were going to retain the work while parting it off. Truly amazing.

wunderschön!....I really enjoyed watching your video. I was intrigued as to how you were going to machine this tiny little lever on such a large milling machine. I'm used to turning/milling much larger stock, so watching this literally had me sitting on the edge of my seat...Absolut klasse!!
Great video! When the drill broke in the part said out loud "Oh $h!t, I feel for you!" I don't have enough fingers and toes to count how many times this has happened to me no matter how careful I am trying to be. Great jokes keep them coming in future videos. I am now a subscriber! Cheers Todd
Great work. These parts are tiny. For the lever on 44KS, I think the purpose of the thin part was to reduce/control the pressure. As the only Seiko watch with hack function, the lever is pushing on the disk that is press fit on the 4th wheel top pivot. The pivot is on 4th wheel is 0,14mm. I think this was just a design flaw. For other Seiko with hack function, all levers are pressing on the wheels rim. Some on balance wheel and others on 3rd wheel. A watchmaker approch would be to cut the lever out from sheet metal. Then drill hole, make the tap and file, file and file :)
I always try to drill the tiny holes first. One of the parts I make has a 0.5mm diameter hole that's 19mm deep in copper. I use 0.4 mm pecks at 12000 rpm with a Noga-Cool Mini mister. Always fascinating to see how a machinist makes a part like this compared with the traditional watchmaker's technique. For very fine holes 0.2mm-0.5mm I use high quality carbide large-shank PCB drills with a high-speed spindle and a microscope. My eyes are getting old and tired!
Great video as always! I would have kept that small piece of stock too 😂. Now you need to find a new piece for that occasional lathe part or press adaptor.
I have never seen a hack designed like that before where it directly contacts a disc on a pinion. Hacks typically operate against the balance wheel by friction.
Well, all such levers and springs are prone to breaking in two general reasons: bad or wrong tempering/annealing cycle or because of insufficient surface polishing. The second reason is the most likely this Seiko have. As I can say from my personal experience, such parts with highly polished surface are much less prone to cracking or breaking, as they are have less points and lines, where stress can accumulate.
Alex, nice work as always with great humour as well. A few thoughts on your process; why did you drill so deep for one thin part? Did you plan to make more from the same stock? Maybe a tip; after breaking the drill, which every machinist experiences ones in a while, I would have cut the part with a carbide sawing blade. This would cut the left over drillbit in one swoop too. Just my thoughts standing in the harbor watching the ships go by. Thank you Alex.
Very nice work and video. Question: Have you tried Guhring brand 2 mm shank HSS pivot drills for drilling sub-mm diameters? In my experience, they work beautifully in tougher materials and work hardening materials such as 316 SS. Thanks again for sharing these videos. Cheers, F. C.
Beautiful workmanship as usual Alex, and thinking through the problem as well. I have a question for you : I'd like to try out the tapping chuck you made a few years ago using spline shafts as collets for the taps. Could you share details as to what type of clutch you used?? Thanks! 😊

would you consider making a video about compound angles. I saw adamthemachinist in the comment section. He had a video grinding one, but gave no details. I looked at my Machinery Handbook, but I just don't get it yet. ps Nice save on the part.
I just learned one more thing- perform the machining steps from what's most likely to scrap the part to least likely... drilling a .6mm hole?. I shake like an addict so small parts like this would make me go mad.
Why is the hack lever undersized? My guess would be to protect the rest of the movement. I've seen many different things in watch repair but this certainly goes above and beyond. Very good.
I rate this video with 10/10 magnifying glasses.
I'm waiting for Clickspring to show up here

Also useful technique when you want to destroy a broken tap with an old ball mill

Tempering a part like this with that thinning curve in the middle wouldnt that cause it to warp significantly?
I'd probably get it printed these days 😅 probably need to put the pin in and hand file the pawl to sharpness.
@@jamesmccaul2945 the same way, to measurements.

An absolute amazing video in terms of content and presentation. I would have paid to watch this.

Absolutely excellent effort. I make watch parts on a 6mm and 8mm lathe. Seeing you handle larger machines with such finesse is very, very impressive.

It's well worth having a set of solid carbide PCB drills with 3mm shanks for fiddle-arse small parts
Unbelievable workmanship!!!!
I now question and doubt my intelligence and knowledge.
Beautiful work.
Thanks
That was amazing watching that part being made.
That measuring screen was incredible, im not a machinist or into watches so im not sure why im here but you had me hooked great job
Alex, nice to see a new video. They are always welcome. I can see an EDM in the distance.
32:56 the good old 2/100th for press fit in watchmaking

You too? I felt a shiver down my spine when I saw that beautiful scrapes
Very nicely done!
Amazing work.
That is soooooo impressive!
Very interesting...
When drilling small holes use the quill stop to control the depth of each peck. Yor machine may not have one.
nice one
oooh-ahhhh... great job!
The lever needs to be flexible and adjustable to prevent damage to the stem carrying the seconds wheel
Very impressive👍
