As I recall, Chris over at ClickSpring made his own involute cutter, but instead of cutting the relief with a step system like this, simply took the unhardened cutter back to the rotary table, and milled the relief behind the point. That wouldn't relieve the entire curve, but I think his point was that most of the cutting action that needs the relief is in the depth portion of the cutting. All that said, it's probably time to go back and re-view his series of videos on that process....

I love that you make tools instead of products. I cobbled together a milling machine that holds my '50s 10" Atlas lathe and take advantage of the power feeds of the lathe for the table attached to the tool post. Everyone asked what I was going to make with it. My response was the mill was the project. But then I made v blocks to hold a acme lead screw for the lathe and machined and cut the keyway for the cross feed in my lathe. Then made a fly cutter to mill the table. None are at your quality level because I never was a machinist. I learn from you, Blondi Hacks, Abom79 Joe Pie and AVE. I also bought some gear cutters for the lathe because I could only make 16tpi or .0015" per rpm. Never made a gear because I bought the ELS components from Clough 42. Now I dial in the tpi, metric or imperial, or thou per revolution. Check it out.

Combining the pantograph with a 3d print would be such a sweet combination of new and old technology

[@ProtonOne11]

Yeah, would have been cool to have the text 3D printed as the template in an arc ,so the text would be curved on the gear cutters as well. I don't think there is an easy and fast way to curve the text otherwise, you would have to readjust the gear cutter after every single letter.

[@millinoid2151]

This is a really cool idea. 3D print the entire alphabet in various degree offsets left and right so you could build arced lettering for the pantograph to copy over… although storing that many unique letters for it would be a bit of a nightmare

@@millinoid2151 Probably need a side project for a sane storage system...

[@mrsockyman]

@millinoid2151 it's a great blend of one of the cheapest cnc machines, with elegant manual machining

[@RNMSC]

@@mrsockyman An alternative might be to create a set of letters that are all uniformly spaced and the sides are all angled for a given center diameter, then a mounting plate to set them up in a circle, center the circle under the pointer, and adjust the center and scale of what you're lettering so that the pantograph cutter ends up where you're looking for the lettering to be. You end up with a single set of however many letters you want and (go get a Scrabble set and use the number value of each letter to divide 10 by (or whatever the value of Q or Z are) and make up that many of that letter. Numbers might be a different issue, but you should end up with something like 38-40 letters, numbers and required punctuation. More if you are going to include various other symbols in machining such as theta, center marking, etc. Which simplifies thins from trying to decide do I need 360 of these for any angle on the pantograph, and how am I going to align everything so that the cut ends up where I want it for each letter. One of the interesting things of watching JSK-koubou, is the realization of just how much you can do with what seem like really basic tools, if you go at using them from the perspective of using precision as your own mindset.

[@Ratzmutz]

As I understand it, the key aspect of gear cutters being 'form relieved' is not just to prevent rubbing, which could be achieved with a bench grinder. However, simply grinding them would only provide relief without preserving the 'form'. The critical difference with form relief is that it ensures the cutting geometry remains consistent with each sharpening. This is achieved because the relief is shaped using the same profile that was used to create the original cutting edges of the gear cutter. This way, the tool retains its intended cutting geometry throughout its life.

[@Gottenhimfella]

That's exactly right, in the case as you say of gear cutters. A tap is also form relieved, but unless it's tap #1 or #2 from a serial tap set, you can't resharpen it without taking the resultant thread diameter below spec.

Its amazing how much the quality of my day improves with a new IM video.

[@scottsmall9898]

I must say the last video showing your tool working didn't do it justice. Seeing it working in the lathe cutting your reliefs was just beautiful. Great job!!!

Very good heat treating. Very neat holder for your part! Keep the parts in the oil during the quench, you'll get less smoke and a better quench.

how great it is to see a project come together!! i was completely lost on your recent videos but this one totally made it click for me, great job

[@AutoAgentcoza]

I'm blown away. That was way more daunting than anyone would actually know. I salute you (and your wife).

My god, those finished gears are beautiful. Maybe because I know how much work went into making the tools to make the tools to make the gears ^_^ Everyone needs to have a friend/partner who is as enthusiastic about our hobbies as Mrs Inheritance. Her joy is pure.

I don't remember much from my time in a machine shop, but your videos are always excellent and fun to watch.

2 minutes in. Production and meme value is insane

[@RussellTeapot]

18:05 that was exactly my reaction when I saw the finished gear cutter, don't know anything about engeneering or machining, stumbled across this channel by accident, and I've been mesmerized by the beauty of these fine pieces

You need to do a project series with her man. That would be the coolest and funniest series ever for the maker youtuber community!

Love your videos and your wife’s excitement to what you do. She rocks.

Every time your wife expresses unadulterated joy and genuine fascination at what you do and what you've made it adds a year to my life
