Making a Custom Gear

In this video I'm going to make a custom gear for my lathe. This special gear is needed to have additional feed rates to turn threads on the lathe, especially 26tpi. My lathe can cut a ton of different pitches, but not 26tpi. To cut a thread with 26tpi you'd need so called „special accessories“, which is just a special gear with 46 teeth and 52 teeth to replace the standard gear with 21 teeth and 28 teeth. So I decided to make my own. As I don't have any gear cutting milling tools I decided to make the special gear with two welded together normed stock gears. I was able to order them online for $25 each. After welding them together I made the bore to the proper size, turned three grooves and cut a keyway on the arbor press with a 5mm keyway broach. It all worked out as planed.

I hope you like my work and the video.

If you have any questions about the process, machines i'm using or other stuff, just ask me in the comments. I read them all and i try to reply as soon as possible.

Sorry for my bad english, it's not my language. I try my best to improve my technical english.

Thank you for watching :-)

Thanks for the green "eyeshade" while welding - I know I won't get "arc-eye" from a video, but it does make it more comfortable to watch. As always, attention to the little things make your channel stand out above everyone else.

I've been a professional draftsman for over 18 years now, and have called out run-out specs in GD&T per engineer's direction. Until now I have never seen that actually managed from a machinist's standpoint. Just so used to that being validated by the QE in the metrology labs. Love ALL of your videos by the way! Cheers from the US!

Grounding through the vise screw is a great way to either get poor welds because of the grease on the screw preventing a good connection or to ruin a screw or nut due to secondary arcing.. Fine if it's a $20 Chinese vise, but a bad thing on an expensive or antique vise.. If you are welding in a vise vs a fixture, clamp to the body or jaw of vise. Our shop vise actually had a tab on the side of the body for a grounding clamp.

It's always a pleasure to watch you make something. For these few minutes, the world seems sane!

A lathe is used to make a part for itself. This is how the machines will rise up one day.

[DanKoning]

All I can think to say is "man I wish you made more videos" [on either channel]. Well done.

6:01 That Dremel speaks German, it goes up to every sharp edge and goes
"NEIN NEINE NIEN NIEN NIEN NIEN NIEN NIEN NIEN NIEN NIEN NIEN NIEN"

Als zerspanungsmechaniker geht einem da das Herz auf 💕

[marcoschwanenberger]

Aaah. You DID allign the Texts with each other! And the keyway! My satisfaction is complete! Kudos!

[natechucks]

The welding mask screen effect is a really neat idea that I don't think I have seen anyone else on YouTube do before. I like it. I can genuinely see some people having issue with the arc being too bright on some of these new really bright displays.

You made me understand thoroughly the principle of a gearbox. "Spinning levers" as they call them. I have worked as a machine technician for a few years and until now that I see your video I completely understand the concept. Your video was helpful beyond its intents.

Danke vielmals!

[mattroth]

After watching your videos for past year or so, I was completely prepared to see you meticulously machine all the teeth on these gears. Still never a disappointment. Keep up the great content!

I make my living as a fabricator. I do this sort of thing all day long, day in and day out. And here I am watching someone else do it during my leisure time...

Is there something wrong with me?

[nexultima]

i did not understand what it was for at first, but i see shiny metal with precision craftsmanship, i watch and i hit like button. very simple. :)

[brahimvlogs]

only few in the world can do this ..
this is awesome

[ImBk]

I'm so in awe of your work and so many of your skills that, as an experienced welder myself, it's oddly comforting to see your less-than-pretty welds in between all the other amazing things you do.

[lucyx]

my friends and i like to refer to the lathe's carbide cutting edge as "the funny bird who likes to eat metal". needless to say, this video was a beautiful and exciting adventure for the funny bird; it got to go all the way into a cool tunnel

[GerryG]

It is always fascinating to me to see a machine used to make a part for itself. using a lathe to make a part for that lathe is beautiful in a way.

[tracybowling]

Wow! I really like to watch you work. It's always fun. You can do ANYTHING!

[WeCanDoThatBetter]

Who else expected you to mill the gears out of a blank? :D But anyway a nice video!
