Just re-watching this, I'm really enoying this. I'd like to try to make a gear at some point.
John S Dilsaver
2022-07-17 17:10:22 +0000 UTCAs always, work continues - Cheers :)
Clickspring
2022-05-29 19:52:37 +0000 UTCWhat happened to this project?
Dustin Graybill
2022-05-29 18:04:01 +0000 UTCSome of my mates use a small 2-flute milling cutter. You can use a broken/used one as it only needs to be sharpened with a single face.
David Paterson
2022-03-25 05:39:09 +0000 UTCAs for the small boring bar, I have used a parting tool and ground it down until it became a small boring bar, It works great!
Borislav
2021-12-26 23:24:27 +0000 UTCSo pleased to hear that Mike :) If I scale the cuts down to match the size of the machine it really does a great job, even on harder steels like the pivot steel. Its easy to forget tho, and go a little too hard on the cuts! - Cheers :)
Clickspring
2021-12-18 05:24:55 +0000 UTCI love watching you make parts for projects. How hard is cutting harder steels on the jewelers lathe?
Mike oliver
2021-12-18 04:49:27 +0000 UTCHello mate, Yes the Antikythera reconstruction continues as a long term project - Cheers :)
Clickspring
2021-12-11 21:58:10 +0000 UTCHi Chris, good to hear from you again. Are you still going to finish the antikithera mechanism?
Liebel Schlesinger
2021-12-11 21:55:57 +0000 UTCThank you mate :)
Clickspring
2021-12-09 04:19:03 +0000 UTCThank you mate, so pleased you are enjoying it :)
Clickspring
2021-12-09 04:18:54 +0000 UTCHi Evan, yes the train is indeed lightly preloaded as you suggest. A small hairspring provides the backlash compensation - Cheers :)
Clickspring
2021-12-09 04:18:28 +0000 UTCNice to see that Charles Frodsham & Co. are now one of your Top Tier supporters :) Good on you Guys.
Duncan Luddite
2021-12-08 22:52:35 +0000 UTCBEST 1$ I ever spent. This project inspired me so much. Thanks chris for the amazing content.
Rickwest Sampaio
2021-12-08 19:24:31 +0000 UTCI always imagined that these things would have internally preloaded gear trains. Is it just that with such fine teeth and tight lashing, the backlash is small relative to a dial increment?
Evan
2021-12-08 15:10:53 +0000 UTCGlad you enjoyed it Christopher. The Antikythera project continues - Cheers :)
Clickspring
2021-12-07 05:31:38 +0000 UTCLove the video! Just hoping that progress on this doesn't mean that the Antikythera project has been scrapped....
Christopher I Lehrich
2021-12-07 04:41:54 +0000 UTCTryally Tools makes a quick-change toolpost that can work as a substitute. It's a wonderful tool, not too expensive, and they're great about customer service.
Christopher I Lehrich
2021-12-07 04:40:46 +0000 UTCThanks Mate, amazing project!
David Few
2021-12-06 06:46:36 +0000 UTCHard temper engravers brass - Cheers :)
Clickspring
2021-12-06 06:44:29 +0000 UTCWhat brass are you using for the wheals Chris?
David Few
2021-12-06 06:37:11 +0000 UTCDid you foreshadow different projects when you said this project is a gateway to smaller ones?
Paul Devey
2021-12-06 04:15:41 +0000 UTCYes it is, in the meantime there is a little more detail on the casting setup here: https://youtu.be/8nU0rEGo-wU - Cheers :)
Clickspring
2021-12-06 04:05:52 +0000 UTCThank you mate, yes a fun set of side projects will parallel this build - Cheers :)
Clickspring
2021-12-06 04:01:22 +0000 UTCAt least three times more accurate and preferable ten times more accurate.
Ben Manthey
2021-12-06 03:00:13 +0000 UTCThis is awesome! Great to see Clickspring taking on a project at the watchmaking scale. Very interested to see how that case is cast, my amateur eye tells me it won’t be a traditional sand cast with the undrafted surfaces. Is investment casting in a home shop going to make a debut?
Paul Readel
2021-12-05 16:37:28 +0000 UTCI cannot imagine how small the margin of error is when you're making a tool that literally measures margins of error.
naota3k
2021-12-05 07:03:11 +0000 UTCThis video was worth the wait! I can see in my "minds-eye" more videos, tooling, details, and capabilities as you progress from here. Great job. I hope Mrs. Clicksrping (your better 3/4?) is going well.
Paul Devey
2021-12-04 23:16:28 +0000 UTCThe pivot file/burnisher in the video are store bought ( https://www.hswalsh.com/categories/pivot-file-burnisher ) They are a combination #8 cut file and burnisher, with a parallelogram profile that permits action into the 'corner' of a pivot shoulder. The tool is approx 3mm x 6mm x 180mm, with the working surfaces about 70mm on each end. The burnisher could be made from an existing file as you suggest, taking off the teeth and then a careful grind to establish the profile, or from scratch with gauge plate - Cheers :)
Clickspring
2021-12-04 21:08:51 +0000 UTCYes, brass is used in commercial dial indicator gears - Cheers :)
Clickspring
2021-12-04 21:01:06 +0000 UTCThe burnishers you used, are they shopmade or bought? Are they simply files with teeth ground off?
Brian Lenz
2021-12-04 18:14:45 +0000 UTCWhen I see dial indicators in use, they take a certain amount of abuse, with the plunger sometimes rapidly thrust in and out. Will brass gears hold up to that, or are you expecting the user to be more gentle? Perhaps the real question is, is brass used in commercial dial indicator gears?
Brad Thayer
2021-12-04 12:20:07 +0000 UTCTerrific to hear that mate :)
Clickspring
2021-12-04 09:24:32 +0000 UTCSo pleased you enjoyed it mate :)
Clickspring
2021-12-04 09:24:11 +0000 UTCYes, slow work!! Cheers mate :)
Clickspring
2021-12-04 09:23:56 +0000 UTCTrue, but that little gadget is really just to spoil me! The CNC divider isn't at all essential to any wheel cutting project; lathe spindle division can be done with something as simple as a bit of wood and tape measure, or perhaps a little more presentably with a division plate and a detent, both of which can be shop made for the cost of the plate material - Cheers :)
Clickspring
2021-12-04 09:13:47 +0000 UTCHello mate, I have accumulated the collets individually over time, you can get them from Sherline here, as well as a box to hold them: https://www.sherline.com/product/individual-ww-collets-copy/ The toolpost looks to be no longer available for purchase. I have it down on the to-do project list! Cheers :)
Clickspring
2021-12-04 09:08:54 +0000 UTCAnd, just sayin'... I doubt that a jeweler's staker (?) is any more expensive than your gear-cutting setup. :-)
Glenn Trewitt
2021-12-04 08:57:46 +0000 UTCHey Chris, I appreciate the video, most featuring the Sherline lathe (which is what I have at the moment.). Could you post what you have for the quick-change toolpost and collet set? (Your link is just for a single collet.) Thanks!
Glenn Trewitt
2021-12-04 08:56:49 +0000 UTCI doubt I'll get the chance to build one for a long time yet but I'm super excited to watch this intricate device come to life! Cheers from Victoria
Clayton Mellington
2021-12-04 07:06:59 +0000 UTCThanks for the simple explanations. I'm not an engineer or machinist, so a Dial Indicator always seemed to be witchcraft to me. This had me go, "Well, that would just work then!" Love how such precision seems so simple and so hard at the same time.
Andrew Webster
2021-12-03 22:12:38 +0000 UTCAbsolute delight to watch, Chris! Must have been some fun, grinding out that minuscule boring bar :)
Dan
2021-12-03 19:52:50 +0000 UTCYes, the finding has significant implications for the rest of the build - Cheers :)
Clickspring
2021-12-03 18:31:21 +0000 UTCCheers mate :)
Clickspring
2021-12-03 18:26:16 +0000 UTCCheers James :)

Clickspring
2021-12-03 18:21:30 +0000 UTCExcellent video as always, Chris. Really needed this after the last few weeks. Thank you.
Justus Dehegovit
2021-12-03 16:55:44 +0000 UTCBRAVO! And thanks for the plans. It's nice having those to look at as you're progressing through the build.
James Korman
2021-12-03 16:11:47 +0000 UTCYay! ... Looking forward to the next vid!!!!
Thomas McGinnis
2021-12-03 13:56:48 +0000 UTCOutstanding work all around as usual!
Mike Michelizzi
2021-12-03 13:43:59 +0000 UTCHave the research results in your paper brought about a mid-project design mod? (Not a problem, just curious.)
Sean Kirby
2021-12-03 13:22:37 +0000 UTCAhh, I needed that after a rough week. Ta. :-)
Sean Kirby
2021-12-03 13:20:17 +0000 UTCFunny you mention cycloidal vs involute gearing profiles. I was just designing and 3d printing some gears for a future video and learned about the relative benefits of involute profiles the hard way. As in, I picked the wrong option and things simply won't run smoothly unless you set distances *just right* :) As you say, involute is much more forgiving. Great video, as always!
LeoMakes
2021-12-03 12:54:26 +0000 UTCThank you Chris...Another informative and enriching video!!
Roberto Di Martino
2021-12-03 12:38:08 +0000 UTCThank you Stefan!
Clickspring
2021-12-03 10:19:57 +0000 UTCThe size of the parts insane and the tiny boring bar is almost comical! Astonishing work as always, Chris!
Stefan
2021-12-03 10:14:18 +0000 UTCThank you mate!
Clickspring
2021-12-03 10:00:47 +0000 UTCSweet little machine for the price.
Clickspring
2021-12-03 10:00:37 +0000 UTCCheers mate :)
Clickspring
2021-12-03 10:00:07 +0000 UTCYes lots of casting in this project :)
Clickspring
2021-12-03 09:59:55 +0000 UTCCheers mate :)
Clickspring
2021-12-03 09:59:25 +0000 UTCMaybe just a quick peek... :)
Clickspring
2021-12-03 09:59:05 +0000 UTCSo fun video!
rolf redford
2021-12-03 08:22:51 +0000 UTCHoly hell... that is beautiful... wondering how to get my hands on a sherline lathe...
chris grainge
2021-12-03 07:39:00 +0000 UTCIs it OK to watch this during daughter's ballet recital ?
Andrew Smith
2021-12-03 07:34:25 +0000 UTCLoving the art deco theme
Matt Waite
2021-12-03 07:29:54 +0000 UTCI complete the prototype, all drawings and process flows etc before shooting any video. Then I shoot the videos one after another, and as soon as each one is finished they get posted here - Cheers :)
Clickspring
2021-12-03 06:29:10 +0000 UTCLove this project! Less intimidating than a füll clock build, yet we get to learn more techniques. I assume the case of the indicator is cast?
Damian Sutter
2021-12-03 06:26:57 +0000 UTC.... I was just watching Kurtis - at Cutting Edge Engineering (also on the upsidedown part of the planet) make a boring bar just last month 🤔... albeit a slightly larger one 😎 ... Very much been looking forward to this series!!
SA Sampson
2021-12-03 06:26:37 +0000 UTCCheers mate :)
Clickspring
2021-12-03 06:20:50 +0000 UTCHow far out to you do the project before you post it? Do you finish it completely before posting?
m_tini
2021-12-03 06:19:09 +0000 UTCLET'S GO!! Love the new project. Super useful tool.
m_tini
2021-12-03 06:16:23 +0000 UTCHello mate, much research to be done, so hard to say. You'll hear about it here first - Cheers :)
Clickspring
2021-12-03 06:13:33 +0000 UTCHowdy. Perhaps I've missed it -- when do you anticipate finishing up the Antikythera project? Cheers from the US.
