Yes correct, its easy enough to align the buttons by eye and in practice the error tends not to matter enough to justify further complication. This approach is itself an approximation (using circles to approximate an involute curve), with which further small compromises are combined to complete the cutter formation process. It's worth noting that the commercial involute cutters also have a compromise (cutters spanning ranges of tooth numbers) so that any way the problem is sliced it will inevitably require acceptance of compromise - Cheers :)
AIUI the shape and orientation of clearance cut into the top of the buttons has no direct effect on the form of the cut. It is only the 5 degree (or so) angle cut into the holder and matching buttons that has a small effect by making the cut elliptical instead of circular. For a button I did the calcs for (can't remember the details now) 5 degrees made less than 1/100th of a mm which is negligible. 15 degrees does make more of a difference though so IMHO, keep the clearance angle smaller rather than larger for these cutters.
Thought you were making a butterfly knife from billet there for a second. 😉 But now I definitely want to see Clickspring make the most precise knife on RUclips!
Wow I use to watch another gentleman that was a clock builder as well. He also made a cutter just like the one your building. His channel was robert4522 he hasn't posted a video in 2 years though , I keep hoping one will pop up and that everything is ok. He was making a gear cutter I think when he made the same tool. Very interesting.
Does anybody else find it strange that he just freehands the alignment of the cutters? For someone who operates with so much precision it feels weird to have them set in at roughly the right angles without any indexing.
If the cutters are for involute tooth cutters the cutter form is an approximation over the range of the teeth the cutter can cut. If you want true involutes forms you need to cut gears using generation methods (hobbing or shaping). Cycoidal toothed forms (clocks) are probably a different matter. Unfortunately outside my experience.
@@mpetersen6 true, cycloidal cutters use a different form than involute cutters. Cycloidal cutters use a round form and that’s probably what Chris was making to make himself a cycloidal cutter. They are used for making clock wheels which reduce friction compared to involute.
Keep in mind that with his level of skill, by eye and by hand is within a few degrees or tenths. There’s something to be said for having done something a few thousand times.
Oh cool and hey I have a possible suggestion for a side project for ya try and make a ball turner so you dont have to keep grinding specialized profiles for tools you might not use very often
The cutter is intended for making single tooth gear cutters. Often done for home made cutters. Chris has an excellent video where he makes a single tooth cutter with four cutting faces.
Hi Chris I am looking at making the Eureka tool so I can make my own 12 tooth cutters. The information I have gives details for button tools for involute gears. Where can I find details for the tool specs for cycloidal gears?
What was the coating applied to the cutters earlier? I thought it was a sort blueing, but now I'm thinking it was a nitride of some sort. Is this true?

Hmmm i guess the exact angle of the cutter not that important?

@@ClickspringClips Not as applicable here but another word for compromise is tolerance. :) Great work and keep it up!
Ok now we need to see how it's used. More info for the intrigued. Lol Outstanding as always Chris.
Here you go. - ruclips.net/video/Cml_ZaleUuk/видео.html
Thank you mate, be sure to tune in next week :)
Love your videos! And hello to Adam Savage when he watches this :)
Wait no, that's not enough, I need more. What's going on? Moooooore clickspring please 🤣
Could watch your videos all day long. Thanks.
Wow, can't wait until next week to see it in use!!

Looks to me, like a blade for an apple peeler!!! As usual not a clue until i see you use it.
Hell of a job though, Chris.

That is some bloody satisfying viewing 👍

He did that in the last video too.
Slightly triggered my OCD.
I think Chris would have aligned them correctly before pressing them in to the final depth.

The man has definitely got skilz!
How do you get the angle of the buttons in the right orientation when mounting in the holder?
Perfect as always

Привет друг!) С Новым Годом!!!) Пусть ваш дом будет полон любви, уюта, счастья, тепла!!!😊👍👍👍🍾🥂
These clips are nice, but I miss the full videos with commentary and explanations.
Dunno why - they are all referenced in the written introduction. However this one is restricted to patrons.
Nice work
May we see it in action?
Great video. How is the antikythera project coming?
So I am guessing that this is some kind of form tool?
I wonder if the final alignment was made with some kind of optical system, and that’s the reason you polished them to a mirror finish
See pinned comment ^
I have to wonder how often you re-use these impossibility gorgeous pieces of machining.

Tools to make the tools 👍
Was clocking on the polished peices critical?
i love handicrafts🤗🤗

They were tempered - to straw yellow.
What’s it used for? Sorry.
Ah yes, making the tool to make the tool, so you can make the part.
You're going to have to demonstrate how this is used. I still cannot understand why there are no registration pins, marks or other guides on this.
G'day Chris TFS, GB :)
Why did you stopped publishing on your main channel with 600k +subs?
What are you doing? What are you up to now? I'll be watching you!
Make the machine to make the machine.
Oi😺
Boop
this tool is useless for landscaping
Nope, still none the wiser. It's fabulous though, whatever it is...
WTF is that
