Question! What are the drawbacks, if any, of adding a mark or notch, however minor, to the shafts of the button cutters for more accurate and repeatable alignment, especially for the sharpening? Or as another commenter asked filing a spot flat where the grub screw would be expected to reach?

I was thinking the same thing! Really incredible design, this is the only real improvement I could think of... But... You can actually keep the set screw loose and gently press the buttons against a flat surface, where they will index to exactly the right position. Then you tighten the set screws to lock that orientation. It would be a lot more precise than trying to match up any sort of marking. Probably more precise than flats too.

You could actually file a small flatspot onto the shaft of the button inserts. That way the grub screw wont deform the shaft and also it would set the rotation pretty close to what it originally way when you want to sharpen them.

When the 15 degree rake angle is milled in from the top (as at 6:54), it would be very easy to mill a flat at the small (unused end) as the next operation. That would involve no further setup and it would provide a means of orienting the buttons in the cutter. If you used a square that had equal width limbs you could both assure that the buttons were 90 degrees to each other and 45 degrees from center.

I was thinking similarly you could score a line on the bottom of the tall side of the button to make the angle more visible

If you milled a couple flats on the low sides, you could use them to quickly line up the cutters for sharpening.

Just when you think you have seen it all. Chris comes out with another video. Very nice.

It seems like a small flat on the back of the buttons would greatly help align their slope parallel to the stone...

Making the tool that makes the tool that makes the tool to make the part. Phenomenal as always!

Sometimes the beauty of a tool is enough to justify its creation, as in the case here. That sharpening jig is wonderful

Holy chit, Chris, for once I may have an idea for you. When you are forming the original 15 degree slope on the button cutters, once you are finished milling the shape, what if you made a flat on the low side of the cutter buttons. This would allow you a flat surface to index and measure to when setting the buttons for the remainder of the set ups for sharpening on the stones and setting them in the tool holder. Just and idea here, might work.

You could file or scratch an alignment mark onto the cylindrical edge of the button cutters before cutting the 15deg angle on them, so that you can repeatably line them up in future.

Wow that self jigging feature for the cutter rake is really clever!

Thanks to Chris, I now believe my dream of building a model engineering machine shop in my 20’ shipping container is possible.

Amazing. Can i make a suggestion? Why not mill a flat on the button cutter shank for indexing? A small flat that the grub screw can seat into ensuring accurate alignment.

I could watch your videos all day.

Great illustration of using the disk cutters and how to make them... I had read extensively about this over 20 years ago, but only now understand everything...

Love this. Wanting to make gears soon and all these tools that i need to make will make life easier. Thank you for sharing it all. Its assisted in my thoughts. Would putting some flats on the back (thin side) of your buttons not assist in getting the 15 degrees in the right place for sharpening and also for installing on the button carrier with a square to get the high (thick side) as the point of contact? Cant wait for the next and keep up the work Thanks and regards, Paul

Just love to watch glorious tool making :D

Just an idea! But to adjust the two cutters to the same gapped height for sharpening, could you use something like a spark plug gapper "coin"?

Hey Chris, @10:04 I wonder if you could use a piece of glass, sort of like microscope slides (maybe a bit more tough), to press gently against both buttons allowing them rotate to face the same plane, until seen aligned correctly. One must be careful not to break the glass though.

The building blocks, thanks for the look see.

These videos are at the top end on KZread content

Fascinating.

Could you mill a flat at the lower edge of the buttons without impacting performance. That could help with squaring the buttons to the right orientation.

i'll be making one soon. thank you sir!

Great, thanks for sharing

Your work and attention to detail is simply stunning - thank you so much for sharing this with us! One more question: You ground and polished the top of the cutter - doesn't the side surface also play an important role? I mean, if there are scratches there, then they may also be found on the cutting edge - and thus ultimately on the teeth of the gear, which are milled with it?

@nrml76

It is the edge that matters. Because of the 5 degree tilt for clearance /relief after the buttons are mounted in the tool, the sides should not rub against the work piece.

Absolutely genius

Sir, you are awesome.

Hi Chris, your work and videos are totally amazing and inspiring. You refer to the "calculator" many times for making the clock wheel and pinion cutters. Where can I obtain the "calculator" or data please?

You make it look easy!

Hey Chris, great video again! Deviating from a profile with conjugate action (ie involute mated with involute) should result in the formation of transmission errors in the meshing cycle (these errors being deviations from the ideal transmission ratio). You're certainly right that the approximation is pretty good though. Out of curiosity, have you ever noticed little jerking motions or accelerations while two gears mesh together?

It's very possible that either the gear was mounted off center or the shaft is bent either would lead to intermittent binding then being too loose.

Just one word comes to me : wahooo !

Made my day

Do you think flats on the shaft of the buttons would be helpful with alignment and avoid marring of the shaft.

Consistently good videos time after time. I just wish I had the patience and ability to turn out products like these.

Love this mate, thanks! There are a few points in the video where the machine sounds almost drown out your voice.

Dear Sir, today I watched a video by Sabine Hossenfelder. It featured a quantum computer. I remarked how beautiful they were. And as a lark, I advertised quantum chandeliers for sale, starting at $50,000, with two yeas delivery. I have not the tools or experience to make this a reality. But she did respond. To a different comment. I think there would be a market. I immediately thought of you.

Always glad to see another video. A question I hope isn't annoying. What are your thoughts on using round carbide inserts that already have rake and clearance angles built into them? I guess you'd be at the mercy of their diameters so I should check out that calculator.

gorgous finish

Can you post up the necessary information for figuring out the cycloidal button gear tooth cutter tooling or is the information available somewhere else?,thanks.

Ну ты мастер!) Молодец!) Ждём новое видио!)

i worry about the precision of aligning the rotation of the buttons. do they make octagonal broaches?

Would it be worth adding something to easily index the button cutters?

Mmmm, shiny...😁 I notice that when sharpening the button cutters great attention is paid to the circular 'end face' but that the outer side of the button is left largely untouched from the lathe. I've done a bit of metalwork and old-school machining, but my experience lies mainly with woodworking tools (chisels, planes, saws, routers), and in those cases it's impossible to get a truly smooth, sharp cutting edge unless the meeting faces are finished to an equal degree. The back side of a plane iron, for instance, needs to be kept mirror-bright so that when the cutting edge is sharpened - ground, honed and stropped - no nicks or scratches are revealed each time the back of the blade is exposed. If the front is perfectly flat and polished, but the back is as rough as a ploughed field, the cutting edge will always be wavy and can never be finer than those exposed corrugations. So... would the outer edge of a button cutter benefit from being as finely polished as its end face, or doesn't it matter in this particular application? I appreciate that there's a big difference between making a tool to create a finished component, and making a tool to make a tool to make another tool to make a finished component. Just curious... 🙂

@Clickspring

Yes, quite correct Eli, removal of any turning marks is essential for the best possible finish. It kinda zips by but you'll see I take the perimeter to a bright polished finish as a last step of the cutter OD formation before formation of the cutting surfaces (4:30) The goal being no residual turning marks to corrupt the cutting edge, more-so than a polish, but the idea is the same as you describe - Cheers :)

Hi Chris, I can see that there is end clearance on the buttons on the holding tool ( 5 degree) but there doesn’t appear to be side clearance, is this significant.

If you leave the side screw loose during sharpening, won't it find the natural flat? These are low pressure operations..

Chris, thanks again for this. I have a quick question. I'm still figuring out best practices for some of these operations and it seems to me that the locating boss would have been a perfect candidate for using a thermal interference fit. I know that the Loctite will work, but the shrink fit seems so much more elegant. Or am I just adding an unneeded complication to the job?

@hairymcnipples

11 ай бұрын

Loctite is reversible, easier, faster, and iirc stronger than an interference fit, and also doesn't introduce any stresses into the part. It's also visually indistinguishable from an interference fit, so there really doesn't seem to be a reason not to use loctite. Don't get me wrong, I find interference fits very cool and would probably still do it just because I'm a big dag, but the Loctite really does seem superior by any objective measure.

@hairymcnipples

11 ай бұрын

That being said I'm a former designer, not a machinist, so Chris may have a very different insight into this than me!

What happened to the other series about the calender?

With all those different angles, it seems unlikely that the gear tooth profile actually ends up circular - elliptical maybe ?

The rake and clearance angles mean that the cutting edge is slightly elliptical, and as it's not in line with the centre line of the lathe, its effective shape is a curve I don't know the name of. I wonder if anyone has calculated what subtle effect this has on the involute approximation. The angles could potentially be tuned, but only to a specified cutter radius. I'd rather build a CNC grinder with my teeth than figure that one out.

Ok they made a big Hollywood movie about the Antikythera machine. Do a movie review with This old Tony but form your own perspective.

Why did you not index the tool with a keyway? The measurements are to the thousands, but how do you make sure the tool is oriented to the thousands?
