In this video I cut the pinions for the clock from drill rod, and then harden, temper and polish them.
Another milling operation carried out on the lathe, using a cross-slide mounted vertical slide, a light duty milling spindle, a Sherline motor/speed control, and the Divisionmaster CNC indexer.
I also make an improvement on my Sherline lathe tailstock polisher, by making a tin lap for polishing the pinion flanks.

Abbreviated Transcript:
00:40 So lets get started. I would have preferred to have made these pinions out of EN8 steel, which is a real pleasure to machine, and can also be quench hardened. Unfortunately I don't have any. What I do have is plenty of drill rod, so drill rod it is.
00:52 After cutting to length, I cut a 60 degree taper on the end of the stock.
01:15 So I turned the outside to the correct diameter. And then set up the cutting gear on the lathe. It's pretty much the same as for the wheel cutting. The spindle is indicated square, and the cutter is lined up on the center of the work.
01:38 Although its a bit more critical this time. If the cutter is even a little bit off center, the leaves will have an obvious lean, and the work's ruined. It's also worth mentioning that cutting pinions is a lot more problematic than cutting wheels.
01:51 Brass mills very easily - you can rip into it with the cutter, and providing its all lined up as it should be, its hard to get a bad result. But pinion cutting is something else altogether. For one thing, silver steel is much less forgiving, and really hard on the cutters. So chip control is really important to look after the them.
02:26 To be honest, I'm always a bit on edge cutting pinions, and kind of relieved when its over. It's just so easy to wreck the cutter. I'm taking care of the 8 leaf pinion here, and the 6 leaf was cut in exactly the same way.
04:34 Thankfully it was, but I've had plenty that weren't! The part is then flipped end for end, and given the same facing cut, followed by drilling and reaming. The reamer I'm using here is a piece of the same pivot steel to which this pinion will eventually be bonded. So a nice fit is guaranteed.
05:37 A piece of pegwood shaped to fit the gap, along with a coarse grit, was used to remove some of the tool marks before hardening. OK, ready to be hardened.
06:01 I used this wire basket to hold the part, and I also coated it in a mix of boric acid and denatured alcohol, to keep the scaling to a minimum. A light touch with a file to confirms that the hardening has been successful
08:13 The MDF lap brought up a nice scratch free polish, but you can see its rolling the edges of the leaves, which doesn't look great. So its time to try something better. I put the job on hold for a few days, and ordered in a small round casting of pure tin.
09:11 One shiny new tin lap; lets give it a run. And based on the result, that MDF lap is going in the bin! A tin polisher is definitely the way to go.

Hi Chris. Interesting lapping attachment you built. Suggestion....make a tin plate with the axis of rotation off center. This will give an eccentric surface contact and greatly reduce the potential for wearing a "part" size track in your plate. Most lapping setups I have experience with have multiple motion contact features. Just a thought. Nice work. Always a pleasure to watch.
Your attention to minute details in unparalleled-I am very humbly impressed. Thank you!
+blipblip88 Thank you very much BB, I appreciate your support :)
Yes I have the same comment to make, it is really nice to see that!!
Your videos are done just right. Everyone of your steps are discussed as they should be and it still keeps your attention. Very refreshing tutorials. Thank you.
Thanks for taking the time to watch Jason
I love how when you run into an obstacle, you stop and rethink it through and go completely off the cuff and bang it out. Great job.
Damn, I have absolutely no experience milling, polishing, machining or tempering but this makes me want to start man, just beautiful!
I'd recommend seeing if there's a community hackerspace in your area. They're a great value, and you can start doing some great stuff without an enormous investment.
IOts not so easy and nice as it looks
I feel the same way but at seventy six I think it a little too late.
@@alangriffiths3360 Never too late to start!
"Listening out for uncomfortable sounds from the cutter" certainly is familiar. That was me when running equipment on my father's dairy farm. Also why I got stuck with most of that work: my brother would put a Walkman on, turn up the volume, and not pay attention until things got way too bad. I also remember seeing a show on TV in the US about an off-road truck race somewhere (probably Baja California) where the head mechanic gave the drivers a lecture the night before the race, saying, "the truck will tell you what you need to know, you just have to listen." That stuck with me and I even apply it with my motorcycles now.
Great video! Can you please consider doing a video series on each of your machines (lathes, mills, tools, etc.)? Why you selected them, their specifications, situations where you use them, where you might buy them and rough idea of their cost. I would love to have access to the tools and machines you have to follow along making projects you show! Consequently, it would be helpful if you could also prioritize which machines and tools are “must-have” vs “nice” to have. Thanks!
I have no tools for working with metal, nor do I have any aspiration to do so, but I love the insight and relaxation I get from your videos.
Keep up the good work !
From one Aussie to another... The stuff you make is just insane!! I have no idea how you have the patience to make these things? And when I've seen you hand file things, like the teeth in gears it's just amazing. The tiny things you make are incredible and then when you polish stuff, you get it to a mirror finish. And on top of all that your videography is amazing!!
Thank you mate, terrific to have you watching :)
Hi Chris, I keep coming back to this series as I make a sidereal clock.
I couldn't afford a tin blank so I melted down a cheapo damaged pewter tankard, excellent results using the grits and powders I normally use for telescope mirrors and lenses (Y)
I just wanted to let you know how much my husband and son enjoyed watching this series together. My little guy, Bruce, has been obsessed with these videos from the first time he saw them. He just turned 3 years old end of May and asks to watch "little cut" every day. He likes machining videos with lathes, yours are by far his favorite. We watch the pinion video pretty much every day. You have saved me from hours of repetitive kid's cartoons, thank you!
So pleased to hear that Jen!
I'm just a weekender when it comes to machining/welding etc - but I know just enough about it to know that this is WAY harder than Chris makes it look. Getting all that set up so that the last tooth comes out perfect like that - very cool project and series.
Thanks for going the extra mile to make that tin lapping tool. I'm sold!
+Kognition Wings Works a treat, even better for polishing screw heads - th-cam.com/video/5sAw4Q1PM8Y/w-d-xo.html Thanks for watching KW :)
Вы мастер своего дела. Чего стоит только одно качество видео.
I love the fact you show your trail and errors on your videos. Also your can do attitude is fantastic, some people think that if you don't have a certain steel or tool you're SOL. You show a great resourcefulness in your shop abilities!
Thanks mate, very much appreciate your support :)
The tin was clearly the special sauce. Looking good.
wow, tin lapping plate, that's one I'll have to remember, thanks Chris !!!
I had never seen or heard of tempering the way you did it before now. Incredibly interesting.
silentqueue Thanks for watching. I'm going to be doing a shorter length video series with a bit more detail on things like tempering in the next few weeks, so keep an eye out for it.
Clickspring I look forward to it, great videos!

Using the shavings from the lathe to give an even heating is brilliant.
I was wondering why people were making such a big deal over clicksprings, now I know why. Beautiful just beautiful
I am amazed at your problem...solving... I have an old watchmakers lathe which I am just cleaning up and setting up as a nicely. Polished finish... Never have got the idea of bluing but have learned a little more since watching.your videos... Wonderfully gifted craftsman....and thank you.....
The size of these parts makes the precision and finish all the more impressive. Addicted to this channel!!! Thanks AvE for sending me!!!
I admire your attention to detail most anyone else would have left the lapping as is. not only did you know it was suboptimal but knew how to fix it. marvelous indeed.
+Guy Good Cheers Guy, I appreciate you taking the time to watch :)
2nd video of yours I have watch. admittedly I had been well into drinking tonight. I was utterly mesmerised by the video, music and your voice. You have taken this type of machines video to a new level. I will now binge watch everything that you have posted. Thanks for the videos..
+Paul Gdry Cheers Paul, thanks very much for taking the time to watch :)
It is mentally therapeutic to watch fine machining in action! Thank You!
Ram Radhakrishnan Thanks Ram.
Would you consider doing a tutorial on heat treating and hardening? You are a very good teacher. Greetings from Arizona.
yes, I will do a more in depth heat treating video at some point, thanks for suggesting
You are so clever, I have wanted to build a clock for sometime, now I know I don’t have the skill or the tools 😃
I wish I could do even half of what you do.
Same here, to be half as good would be reward enough for me

+Clickspring, your video inferior porno vids with raccoons, but still very much excite me! This is the porno for perfectionists!
Thanx!
What is this for a Programm (sry for this Englisch i'm german
+Tomes H Let me give it a shot. I understood your question as "Which software has been used" and you're probably referring to the screen grab around 30 second mark in the video. I haven't used it myself, but i believe that this is "SolidWorks".
+Clickspring Mate, you're a glutton for punishment with all that filing. You do a nice job of it, but, cough, CNC, cough!
llllllll
Great video series. It's beautiful and very informative.
Inspire To Make Thank you very much.
Top workmanship .
Thanks Chris for posting these videos. My 5 year old daughter has really enjoyed watching as have I. Can't wait for the next one.
Cheers!
Is your 11 year old daughter still watching?
Absolutely wonderful video
Chris, your artistry, finesse and craftsmanship has no parallel. Keep up the great work!
You are very talented and knowledgable, very easy to follow and learn from! This is something I would be interested in doing in the future, keep the videos coming 👍
patrice numarkioan Thanks for the kind words Patrice, and thanks for watching.
I've cut pinions myself and done for cutting as a toolmaker. a paint brush and some cutting oil or paraffin worked fine if you don't have coolant feed. I do it one my TH-cam channel.
Thankyou sharing this art before its disappear.
nice job, by the way GEM faceters use tin lapse on their faceting machines, as well as scellack to glue the stones in place, looks like this works for clocks too
Unbelievable workmanship, patience, and detail. Thank you for sharing your knowledge. Now I need go clean and tidy my workshop in embarrassment.
+technoshamanarchist Ha ha! thanks for watching :)
machining is an art, I love it
I'm about to get my own mini lathe. Your channel is a huge inspiration to continue my hobby
Never heard about polishing with tin but the amazing result obviously speaks for itself :O
It's usually called "black polishing" or "spéculaire" in the watchmakers' trade. "Spéculaire" (mirror) is easy to understand. "Black polishing" comes from the fact that if there's no light being directly reflected at the viewer, the part will appear black.
I got your site from Alex Steele, you sir, are amazing. I so enjoyed the last hour or so. I subscribed and will visit with you daily. Thanks for your expertise. Perfection is truly perfect!
Yep. Same. Currently binge watching this lad and his work. Makes me proud to be an ozzy.
Same here :D Machining porn rocks!
That was very satisfying to watch. It was interesting to see how a pinion is made. Beautiful work my friend.
I am loving these videos. Watching this clock come together has made my lunch breaks over the last couple of days very enjoyable. I can't wait to see the finished product.
Damon Vandermaat Cheers Damon, plenty more to come. Although I will probably spread the clock video's out a bit, to fit in the tool making video's. Thanks for watching.
First of all, if I could even get a decent sized piece of metal, I would feel accomplished. This is amazing.
Once again, a brilliant presentation.
It's so pretty
Tin polishing was incredible thanks for sharing
Donde estuve tantos años sin saber de este maravilloso canal, 😭
Beautiful as always, Chris. Fascinating about the tin, Never heard that one before!
Very clever, using Brass turnings for tempering...genius!
Great videos
Tin cuts like delrin/plastics
Paul Reason The tin holds the cutting medium. It does not do the polishing!
Excellent work 👍
Had no idea one could work this precisely with metal ... my idea of metal work was mainly informed by the popular portrayal of a blacksmith hammering away at a piece of hot metal to form a sword =P
+JG Sometimes I feel like taking a hammer to it too! Thanks for watching mate :)
Beautiful work bud I have never had an interest in clocks but I would defiantly kill to have a clock smiths machine shop like yours
nicholas turney Thanks Nicholas.
That's an awesome pile of tinsel (literally tin-sel. old school).
+Dominic Muren Ha ha very good! Thanks for watching Dominic :)
Ok, found the tinsel refference.
I am in awe of your work sir!
Some of the best videos I have ever seen. Everything is perfect EXCEPT their is not enough of them. I wish you made a new one every day.
+Richard Billings So do I! I had no idea when I started doing this, just how much time it takes to make videos. I have so many projects queued up ready to go, the only thing I don't have enough of is time! Great to have your support Richard, I appreciate it :)
I like your polish mixing palette at 7:43
+ExtantFrodo2 Ha ha! Yes there's a few things that have gone "missing" from the kitchen, and somehow ended up in the shop... :)
I looked into it, and it turns out the difference between wheels and pinions lies not in the number of teeth, but in the depth of profile. You could stack quite a number of wheels flat to get to the same height as a single pinion standing on end. Some clocks have 10-toothed wheels and others have 42-toothed pinions. As a rule of thumb, though, your statement on the number of teeth is accurate.
Brilliant. Superior to what I could have ever imagined. Keep up the great work
Beautiful work Chris.
Just what i needed... need to hold some pinion stock and now i know how, thanks Chris!
l0ckcr4ck3r Excellent! Cheers mate.
Nice work. I enjoy watching your videos. Your video editing skills are top notch along with your machining.
eddie2799 Thanks very much Eddie.
Interesting video. that really took amounts of works just to produce single pinion
God damn. Every video ends with beauty. Mesmerising.
absolute delight to watch, no nonsense instruction, thank you for sharing your skills.
Barrie meadows Cheers Barrie, thanks for checking it out.
A copper works very well for a lap to polish with too, thanks, love your work!
I always like to watch your Videos but it's like a bonus to see you using german hardware :)
Crazy amount of work all just for one little gear . Man have we lost touch with what it actually takes to make things
Now they just make thousands per day with injecting metal powder in a mold, pressing, then heat-treating.
@@ninja5672 and, if necessary, they can be grinded with the wheels in a few minutes per piece to obtain the right tolerance
This is awesome! back i go to watch the previous four parts...
Beautiful work!
+Frank Hoose Hey Frank, thanks for checking it out. I've been a big fan of your site for some time, in fact you helped me pick out my gear! Cheers, Chris.
I'm honored. I noticed that you were using the SC4 lathe. Your work is awesome!
Yea in high school cutting gears on my machining “final exam” was pretty stressful. 7 credits and 4 years down to 4 projects. When you’re 17, 4 years is a long time. And I’m not a machinist anyway. I’m a die setter. 😂
You put more work into this one cog then i have ever put into anything in my life.
+koulokoe Ha ha! Thanks for watching :)
You bloody little ripper!! Thanks for this video. I am currently tearing my hair out trying to work out to cut some mod 0.2 gears. They are 2.8mm total OD and with 12 teeth. This video has solved a few issues I was grappling with.
+huxleypig69 Ouch that's small! Good luck, let me know how you go :)
+Clickspring Will do! Making the bespoke 0.9mm cutter is proving to be the biggest hurdle right now. I love the cut-out tailstock, I will be copying that for sure!
Here's a question - let's say you wanted 5 gears the same...would you consider making a long pinion (like in this video) and then slicing it up to make the identical multiple gears? Instead of going through the whole process of making 5 gears?
+huxleypig69 Providing the pinions are not too long, and you can support the work in the middle (with a small machinist jack) then that would be the way to go. There's a great book called "Wheel and pinion cutting in horology" by J Malcolm Wild. It has some great information in it would give you everything you need. Cheers, Chris.
thats a massive amount of work for a cute little part like that :o
+Alex Bv Thanks for watching Alex
Your craft is really beautiful man. Thanks for sharing.
I ran gear hobbing machines for years.
Nicely done.
A tin polisher. Wow🤯
Great video I had always wondered how to male pinions and now I know also keep in mind that if the cloth is caught on the chuck it will ruin the work and the tool
Apparently I was wrong about home forges. I watch "Forging in Fire" on TV and I discover that a gazillion otherwise ordinary guys have a furnace at home capable of melting metal. Who knew? Now I read about Home Machine Shops and I think it's highly improbable that any regular person has the kind of specialty tools you use to make your fabulous creations. Seems crazy. Got to go now to continue building my Home Movie Studio.
Impressive work! Thanks for the video.
OMG! so much work! WOW! I just check the time by looking at my cell phone....
top notch machining and cinematography, thats a deadly combination that yields awesome content! Keep it coming!
+Josh Gallant Cheers Josh! I appreciate your support :)
You're a more patient man than I am Mr. Clickspring.
Great video series! I have a Cowell's 90CW on its way in the coming weeks and I think you have inspired me to tackle a similar project with the Skeleton Clock. Many thanks for your efforts!
+big J Cheers Big J, I've read only good things about the Cowells lathes, have fun :)
I was really scared the pinions were going to slip when faced to length, but it seems the brass with an easy press fit provides enough friction to prevent that!
Very nice
Yet another great video. Thanks!
drilling with press fit holding only, is chilling. thanks for all. nice work, nice camera, nice narration, nice editing, equals a splendid channel.
ok. could have leveled up the compliments to splendid/remarkable.
OH MY GOOD ! I WISH I CAN HAVE THE SAME PATIENCE THAT YOU HAVE !!!
+Sebastian Perez Thanks for watching Sebastian :)
Me too
Your best video yet... Made me think about a few things, thanks!
stjohn gold Thanks mate.
God Damm , i love this kind job, I wish have those machines =(
wow good job
This videos is hypnotic! Great work.
+Stefan Lindblom Thanks for tuning in Stefan :)
This is just amazing!
You are a master!!!
Amazing job !
8:57 i wonder if this is where tinsel came from originally?
Very much Enjoy the videos, Great techniques on the lathe, enjoyed ,thanks for posting
TIM WILSON Thanks Tim.
