How To Make A Clock In The Home Machine Shop – Part 6 – Crossing Out The Wheels


G’day, Chris here, Welcome back to Clickspring. In this video, I get started on the wheel spokes, by taking the main wheel of the clock from this, to this. Crossing out the wheels, is definitely one of the more time consuming parts of the build. There are 6 wheels plus the escape pinion to take care, so that’ s a fair amount of filing and hand finishing. I’ve chosen the largest wheel for this video, mainly because it’s size means it should be the easiest one to show the detail, and weighing in at just over a kilo, its a fair chunk of brass. But by the time I’m finished crossing it out, it’ll weigh just a fraction of that. I’m aiming for clean straight lines to the spokes, square corners at the perimeter, and good overall symmetry. So lets get started. First up I applied some layout fluid, to prepare for marking out. This layout blue is an old bottle I’m trying to finish off. Unfortunately I think it might be past its use-by. It painted on ok, but you’ll see later it wasn’t the best to scribe a line on. I’m doing the marking out with the help of this jig. Its based on the design by J Malcolm Wild, Check out the description box for more info. The wheel is centered on a locating pin, and then a center point on the top of that pin
assists the scribing of any circles with a divider. So that takes care of the perimeter and the central boss. Once that’s complete, specially turned pins are inserted in the center hole, and around the perimeter at each of the spoke positions, so that when a ruler is held up to the pins, they define the spoke taper and then the line is simply scribed. Its a huge time saver, and I find I get amuch more consistent result with this jig than without. This wheel has a sort of ornamental pattern around the center, which the jig can’t really assist with, but it’s still a great platform to hold
everything steady while marking out curves. And I think you can see the problem with that old bottle of layout blue, I’m not getting a very clear line, but it’ll do the job. The first step was to drill some holes in the waste section of the stock, to allow entry of the scroll saw blade. Any scratches that I put into the work now, are just more work at the end of the build when I’m polishing, so I figured a layer of tape on the underside of the wheel was a good idea. It’ll protect it from scratches while
I’m working on it with the scroll saw. So thats the bulk of the metal removed, and for the first time its starting to look a bit like a clock wheel. The next step was to tidy up the scroll saw cut with this bench filer. I mainly use these #2 cut files, which are good at removing metal fast, and leave quite a good finish. You can see here the real value of this machine. Because of its vertical action, it makes it
really easy to clear out, and then square up all of the internal corners. And best of
all, the cut is always perpendicular to the work. So at this point, I’m short of the line by about the same amount around the whole wheel, and I’m ready to start the hand filing. The tape can come off, it’s done its job of
protecting the underside. And I made life a bit easier for myself with
the filing, by making this guide. My CAD program gave me the geometry to machine the correct shape, and using a guide will give me a fair shot at getting a consistent
result for all 8 spokes. The wheel then sits on a locating pin, its sandwiched between the plates, and then a dowel pin lines everything up. The idea is that the scribed lines are rotated just beneath the guide, and then its all held tightly with a toolmakers clamp and the clamping action of the vice. Now initially I thought I was going to have a bit of trouble holding onto this wheel to comple te the hand filing, because the wheel is just too big for the vise. But by a stroke of luck, the vise jaw which can be removed was small enough to be threaded through the wheel. Now it wasn’t holding onto very much, and I would have preferred a better grip, but it was enough to get the job done. The next few days will be spent hand filing. So I’m setting up at the bench with plenty of light, magnification, and some needle and escapement files. Most of the files have at least one safe edge ground into them, to help cut cleanly into the corners I started out with #2 cut files, to get the
wheel into basic shape, and I did every surface with the same cut before moving to a finer
cut. And I’m using the guide to keep me honest,
by making sure that all of the surfaces are parallel to the guide, even though I’m still
quite well short of it. Now that the bulk of the metal is gone, and its basically in shape, I can use #4 cut files, and take it right to the limit of the guide. So after a solid day of filing, I’m about half way. I’m reasonably happy with how it looks around the hub and along the spokes; its just short of the line. But theres still quite a bit of work required on the rims, so I took care of that off camera. Next up is the finishing work with #6 cut
files, and from here on I’m working without the guide, so I can get a good look at what I’m doing as I work. The guide has made this part of the job quite painless, its mostly just recutting the surface for a better finish, but I’m still taking it really slow, and checking the result constantly. I’ve got so much time invested in the part
now; I don’t want any slip ups! And then as a last step I used a sharp 8 cut triangular file to gently clear out and square all of the corners for the last time. And that’s another full day of filing. Overall I’m pretty happy with the result. I could probably keep going on this forever, but I’m calling it done now, before I push it too far. A quick rub on crocus paper deals with the small burr raised by the filing. And now we’re basicaly on the home stretch. The wheel is ready to have the inside edges papered, and then burnished. The little strips of sandpaper I’m using are held around a file that best suits the shape I’m working on. I’m starting out with 600 grit. Then 800 grit Followed by a quick touch with the rodico
to remove the brass shavings. before finally finish off with the burnisher,
to give a mirror finish. Burnishing also pushes up a burr, so another quick papering deals with that. And I gave it a quick polish just to make
it more presentable for this video. Although in truth the final polish comes right at the end of the project. And its done, only 6 more to go!

  1. При наличии фрезерного станка, на мой взгляд, очень много ручной работы… Это хорошо руки оттуда )) но все равно, думаю, можно было сделать техпроцесс проще

  2. I love the precision and the attention to detail, but considering all that I have to ask, why do you leave so much filing work with the scroll saw? Seems like you could save a lot of time cutting much closer to the scribe line.

  3. dude i love your vids and camera setup so much!! like your my fav aVe is my brash humor and fucking around machining guy and this old tony is my middle guy.

  4. Well, coolest thing I have made is a Cryptex made by Leonardo da Vinci. I used my Jr. High schools laser printer to cut out all the pieces of plywood for it. I would have to say that Clickspring was the person that inspired me to do this. It has 9 wheels and 28 character, A-Z and a space and a dash. Thanks and keep up the good work!

  5. the whole video , the entire time my mouth was wide open flies almost fly into it.

  6. Amazing. The detail is unbelievable. As a millwright and refinisher, I'm impressed with the process. I feel like I use a chainsaw compared to your work. Brilliant.

  7. I was, no joke, blind trimming my beard with a knife i made in my shop while watching this video, and afterwards I still believe you're the manlier one out of the two of us

  8. Pornography in brass.
    Seriously though; your skill, attention to detail and patience are astounding.
    I have just bought my very first lathe, at the age of 58. My first real project is a Stirling engine, from plans supplied by a Dutch Gentleman by the name of Jan Ridders.
    I thought my manufactured parts were ok, but looking at your your work… well, it is superb.
    Thank you for sharing. The videos are very clear.
    From your videos, I have learned how to adapt my lathe for cutting small gears.
    Inspired by this, maybe I will try a clock.

  9. demasiado complejo y rebuscado. tus otros trabajos son muy buenos pero en este no te doy el visto bueno. se puede hacer con un moldeo demás formas. saludos cordiales desde argentina.

  10. Very interesting, but I had to watch with the sound off, which disappointed me, because I missed your commentary. Endless loops of funky music are not my thing. 🙂

  11. The quality of your work is phenomenal.Paul Kelly say and i am with you Paul this is 100% John from Scotland This is the best yet on utube

  12. It's good that there are people like you in the world. The delicate touch and patience required for such work gives me anxiety. I was a woodworker and loved to push myself in that arena. Your work inspires me to push further.

  13. A absolute joy to watch you working mate! I've only watched a few of your videos so far Chris but I've been really inspired by the thought processes involved and the incredible quality. I'm an amateur silversmith and have learned so many useful techniques for tool making, shaping, finishing etc etc. Your channel is a little gold mine! Thank you so much for taking the time to share 🙂

  14. Chris, your work is absolutly amazing.
    The little stop motion bit at the end was hilarious and those two should get named and plunked into a few more videos, in my humble opinion.

  15. another exceptional video… these are a real treasure… learn something new every time… and revisit old lessons.. .every time… just beautiful.

  16. This video should be a lesson in the difference between a hobbyist and a craftsman. I think a lot of people could do this but few have the patience and drive. Amateur Clockmaking? No, this is professional clockmaking. Amateur clockmaking would be me with a half-eaten jar of glue and some popsicle sticks.

  17. Is we know why the shop is always so clean. He doesn’t feed his tools so they have to eat the scraps

  18. Hello Chris. In this video you rapidly mentioned where you got the design of the scribing plate from. However this went too quickly to hear it properly.  Could you please write it down in the reactions? Thanks  and regards, Herman Krijnen

  19. "Crossing Out The Wheels" sounds like a mediaeval folk song title.

    "Here we go a-wassailing, and crossing out the wheels
    Crossing out the wheels,
    Crossing out the wheels,
    Hey ho! Nonny no! Crossing out the wheels!"

    Sorry.

  20. Two days hand filing one wheel, after putting it through two different machines to get it "nearly there".
    Mmm, ok.
    😐
    I have five bucks says this man's grandfather was Swiss.
    Both of them.

  21. Oh my god I love the stuff you do! How do you get so much perfection?! Is this what they teach in mechanical engineering?! Do I have to do mechanical engineering to do this stuff? How did you get so much money to set up your workshop? Pls reply to some of the questions 🙂

  22. – Honor your skills … and learn … how to Master them . – And then … uar humble an nice .. U know something about life and live it . ( take a lifetime sometimes )

  23. Мне тоже хочется чтобы у меня былр столько свободного времени чтобы его совершенно некуда было тратить кроме как для занятия такой вот…
