In this video I make a start on the escapement of the clock, starting with the crutch assembly and a component that permits a slight adjustment of the pallet depth of engagement with the escape wheel.

Abbreviated Transcript:
00:21 Generally speaking the escapement is considered to be the pallets and the escapewheel, but there are usually a few extra components required to make the whole thing work, and its those related components that I'm making in this video. There's an eccentric bushing that permits a small adjustment of the pallet depthing with the escape wheel, enabling fine tuning of the escapement.
00:41 And then there's the crutch assembly, which receives the energy released by the escapement, and transmits it to the pendulum to keep it moving.
02:17 With the taper formed, I transferred the work to the mill, to put in the other features. The embryo part can now be cut from the parent stock, to form the small clamping slot. But before I make the slot, here's a closer look at the fastener hole. One half has been drilled for clearance, and the other half is at the correct diameter to be tapped for the fastener thread.
05:30 I've got the work set up on this pumice stone to protect the bench, and the heat is being applied using a small butane torch. Up close, you can see the flux run, leaving behind a tiny matrix of silver solder adjacent to the join. A little more heat, and then that solder melts and wicks into the small gap between the parts, while the excess solder forms a nice fillet.
06:56 And I'm happy enough with a tool finish for this part, so I'll leave that as the final surface. The spigot has done its job, so that can be taken off with some abrasive paper, leaving a grained surface finish on that underside surface. The final step for this part is to use needle files and abrasive paper to bring the perimeter to final shape and dimension.
09:06 The bend locations are positioned roughly one third in from each end, and it really is just as simple as getting a good hold of it in the vise, and giving a careful push until its about right. The 3 parts of the crutch assembly are now complete, so a small spot of Loctite on each end is all that's required to bond them together. OK, now on to the eccentric bushing.
10:57 The central axis was located with a wiggler, and then a tiny offset was introduced to the spindle, so that the hole would be formed off center - as the name of the part suggests.
12:46 All three were made in the same way that you've seen in previous videos, using the small lathe. They were then hardened, tempered, and then polished and blued. Ok, so with the fasteners complete, I can start to put a few of the bits and pieces
14:56 Particularly since the eccentric bushing can an additional offset angle depending on where it sits in its rotation. Once it looked about right, I put the frames back together to give it all a test fit.
15:37 I've left the barest clearance between the crutch fork and the pendulum block, to minimise energy loss, and the eccentric bushing is ready to be adjusted as required in the next episode. Which leaves just a few key components to be made, before I can set the clock running.

I can not imagine better anti stress video.
You really make Machining look like a romantic art form.
I thought I was meticulous before watching these of videos. Thumbs up !
This is the first time a TH-cam notification genuinely made me smile. :D
Terrific to have you watching :)
Dude you are an engineering genius.
They should give you an award for best TH-cam video series.
So close, yet so var! I'm not sure you realize amount of joy your channel gives. Thanks so much!
Dropped work just to watch this!
oh man the precision on this build must be insanely high
Anything not perfect in any of the videos in this channel? ... ... Nope. You are just killing it! Amazing!
I watch a lot of TH-cam videos but I have to say Chris that yours are in a league of their own. The videography, music, voice and eecution are just fantastic. Also love that you use your own tools to manufacture even more tools that you need.
Thanks very much for the encouragement Almo, much appreciated, more on the way soon :)
Oh, such beautiful craftsmanship. Great camera work too.
Beautiful work and cinematography. Thank you
I`'ve been almost entranced as I've watched every video. I was only going to say "Thank you". But I must also say, whoever calls you an amateur must be a God. I look forward to more.
Cheers Dean, more on the way soon :)
OHHH!!!! very good news!!! NEW Clickspring VIDEO
I swear this is the best quality video editing and craftsmanship. Love your videos, all of them.
Terrific to have you watching mate :)
You are an ARTIST !!!!! I am a machinist for the last 18 years but not an artist.. there is a big difference..!!
Thanks for the encouragement George, very much appreciate your support :)
the quality & craftsmanship of your work is outstanding & the video production is as well. awesome stuff
Again an enjoyable video, with craftsmanship that is top notch. Every time I see that care for the details, it brings up a smile on my face...pure eye candy...!
I really miss hearing you say "I'll see you ladder" Can't wait for patrion series 3
It's hard to explain now awesome your work/channel is without using expletives. No need to reply. Thanks as always!
So excited when I saw the upload notification, so sad when it was over.
coolest homemade project ever.
I'm not even into machining or clock work but I can't stop watching your videos, very nice work, subscribed:)
Terrific to have you watching, appreciate your sub
I can't believe it's almost done. It 's been over a year and a half since you started this project!
I involuntary hold my breath on some of your final touches. Anyone else?
I've binged on every clickspring vid on yt
brilliant mate, simply brilliant
I hope you build another clock after this one is done. Your videos are amazing!
machining the solder joint is genius. looks great
As an apprentice machinist, I have to say.. Your videos are mesmerizing. Incredibly informative no stone left unturned and always a beautiful end result!
Cheers WW, terrific to have you watching :)
Beautiful work, as always.
Thank you.
It insane, mind blow, I don't have words to discribe you work. Good job mate.
You should be awarded the Nobel Prize for clockmaking, machining and videography.
Still just as amazed as when I watched the first one. Excellent work.
Totally awesome,no more to say. Thanks for sharing. Kindest regards. Joe.
Yesssss!!!! My month is complete now.
Oh hell yeah! New clickspring video!
Exactly what I said!
Oh no another month until the next... 🙃
Thanks to you whenever I see a piece of metal turn blue when I weld, grind, or cut it I think of your channel. Great work as usual.
Terrific to hear that, stay safe in the shop :)
Brilliant,, Click, brilliant! I admire the planning and use of the spigot! Thank you for sharing with us wee mortals. Su Amigo Siempre.
Thank you mate, terrific to have your support :)
The best project I ever seen. Absolutely beautiful!
Yet another video so good it brings a tear to the eye. Wow again!
amazing series! I hope you'll make a video at the end explaining how it all works to people like me who have no idea.
Damn that solder joint looks nice.
Incredible!!!!! You are very skilled!
Awesome again. Can't wait till the finish.
You have amazing craftsmanship. Thank you for the videos. It is facing ting to watch.
I love these videos but the wait kills me!! to be fair it is worth the wait!
Glad I've watched this new video. It is really work of art.
So awesome! Can't wait to see it running for the first time. :)
Stay tuned Igor, first tick of the mechanism will be in the next vid :)
Probably just a bit over a week :)
yea I currently expect a month between vids.
You know how hard it is to binge watch 2/3 of this series and then have to wait soooooo long for the next episode. :)
+Clickspring 😃
What will we watch after this project is done...................
as always, everything is clear and beautiful
Enjoyed every second. Keep on the good work.
I wait about 3 weeks and then start checking for a new video almost every day, sometimes twice a day. When a new one appears there is nothing more important for the next however many minutes. Such wonderful work on so many levels. Are you really just a one man operation? Keep 'em coming!
Yes its just me, hence the long breaks between vids!!
Another awesome video! Great work
Cheers Max!
5 day old comment on a video uploaded 14 minutes ago. tell me your secret please
+NoGiveBacks ツ if you support Chris on Patreon, you get access to the videos early!
I wish I could make things as nice as this.
Man, this content is way too high quality for youtube. I love it
Finally an update! It's like christmas!
Another awesome video Chris! Can't wait to see it finished!
If I had to choose a phrase to describe this Chanel it would be “casual perfection”
I remember a friend telling me that if you had a lathe you could build every other tool in the shop. Never thought that was true, but after watching these I'm starting to believe it.
You'd probably need a milling machine as well.
Joshua Rosen some lathes have a milling attachment, with that you can build a better mill and a better lathe
Tom Lipton would be proud of your filing work!
Tom is the master :)
Nice to see that you finally got a spring loaded center punch. those things are great
Everytime I see there is a new video on this channel I like to finish all my stuff, shower, dinner, relax.... and finally watch this piece of art
Terrific to have your support Alex :)
Wow this production quality is insane!
Brilliant Chris.
I've been watching this for months I can't get enough
Keep up the good work! This is stress reliefing therapy
Absolutely wonderful like all your videos. Thank you for putting them out there.
You are quite the perfectionist, you know.
Can`t wait till you finally assemble this beautiful clock. ;)
you are a genius, awesome video, thanks
Aside from the clock itself (which is beautiful in its own right) your videos are always beautiful. They offer many ideas for improving my own videos (which are pretty ugly as yet).
Watching your Vids is pure Satisfaction and this multiplied by a 32" Monitor is inspiring. ^^
I love watching your videos!!!
There are no words to describe how much I admire your work. Can't wait for the next video!

This is stunning!
spread the word people. 185k subscribers for a channel as awesome as this! Chris deserves a million. I love every single video.
Thank you Brent, terrific to have your support mate :)
I have to agree with Brent. These videos are inspired and the craftsmanship is top notch in not only the machine work, but the videography as well. I love your superimposition of parts that have yet to be made over parts that have already been built (e.g. 15:55.) You really are deserving of a larger following. Keep at it, you're doing amazing work.
Very true. I was just going to comment here but decided to do it on Twitter to share the love. Astonishing attention to detail I sit here in awe watching a true master craftsman.
2 BIG THUMBS UP BRENT...I agree 100%....Chris/Clickspring you are appreciated by so many...Clickspring quality can not be overstated...Jeff
Just seeing that you posted a video made my day.
This series is with out a doubt the best most interesting, well made ,well filmed, subject on TH-cam
and I can't stop watching it
Great video as usual. Thanks for sharing!
You channel is one of the few I watch a 1x speed anymore. Each video is a work of art to be enjoyed!!
as always, simply amazing!!
Great work of art
I find all these videos quite relaxing... and also the way you explain all the process is amazing, I can't wait for the next video. cheers
Really beautiful work with the fork. I love how it turned out.
Beautiful work, excellent commentary, very well done.
amazing work! gorgeous photography!! fantastic descriptions and explanations!!!
a 24-hour video of it running, when complete, would allow us to use such a video... as a clock! :)
Finally, after 1 year plus. Can't wait for the maiden run
Very brilliant work ......
i get exited every time you put out a new video AvE send me here. also your videos look so professional it could be its own tv program.
New Clickspring video!!! This is my favorite channel on TH-cam!
This is all so beautiful. Well done!
The quality of these videos are amazing!
I have been watching this clock come together for over a year now, I am amazed at how much work has gone into this. One of my favorite series definitely. I eagerly anticipate your next video! Cheers.
Getting so close. Can't wait to see the culmination of all your work.
