I think that it is very cool that your wife understands and even enjoys engineering concepts! Who would have thought that making a gear was so involved? They look so simple at first glance.

[@BloopTube]

if im remembering rightly she is also an engineer but decided to work in something else after a few years

[@RNMSC]

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....

[@ahfreebird]

Making gears is really simple...if you start with an off the shelf cutter and engineered gear train design 😅

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.

The way your partner is so enthusiastic about your work. Its so amazing.

It's wonderful how your wife is excited about the things you make. What a man can wish more for life?

[@Trainwreck1123]

I absolutely love how excited your wife is! I don't know if that's genuine or if she's playing it up for the video but either way good for you, having a partner that can show interest in your interests that is (or seems) genuine is a special thing! P.S. Sorry about the several comments, hopefully it is just good for your video engagement 😅 I got to certain parts of the video and felt compelled to add my 2 cents

I work at the LS starrett company (16 years) cutter grind department. I make cutters from scratch all the time 😅 and wanted to let you know that I found this video series fun and enjoyable 💯

"Ah this is what you've been baking in my oven for the past three days" I like it when the plan comes together...and its not just me it makes sense to. Those are some very fine gears you made, who would think that such a lengthy process was needed in order to make a workable part. Its nice occasionally to remember just how much goes into the things we use I see this as important as some one building a smelting furnace and making bog iron into wrought iron, then sorting out the higher carbon bits from it and forging out that steel until it can be used as a workable blade Very cool process and well worth learning and remembering two processes that shaped the world for humans

This channel always helps inspire me when im feeling burnt out from the current work load.. and I've said it before and I'll say it again its always such fun to hear you and your good lady humouously sparring whilst enthusing over projects she has perfected the dead pan "yes dear" tone while clearly loving how excited you are. It's a beautiful thing you found each other.

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. For you to make all that stuff to make gear cutters, which were $115 in my case, shows it's the journey, not the destination. Already love your wife. Chive on.
