I have always wanted to see this done on a Bridgeport where I work we have gear cutters but I have always wondered how it would work on a manual mill thanks for showing that.
I am always intrigued with gear cutting. With all of the machine work that I have done in my lifetime I have never cut a gear. Sounds like a good project for the future.
Come on guys ... GIVE BRUCE A THUMBS UP Thanks for posting Bruce. I wish you had time to discuss your set up and sequence of operations. That's quite valuable information. I hope you can put up at least a quick splash to show off the finished project. Hope you and the family are well and all is right down under. Your weather should be cooling off as ours is heating up here in California.
The main wobble is the upper bush, it has a big hole so not centred just running around in a funny way (I was in a hurry so I didn't make a neat hole and key slot in a bush).
Great job, Bruce! Very well explained and demonstrated with your video. In my case, I made some straight and helical gears in a universal milling machine, but I did not want to abuse speed because there are few cutter I can count on. Now, with your work, you help me to rethink my ways of operating. Thank you very much for your time and teachings. We are attentive to your next emissions, greetings!
Is there a reason why you don't use the coolant pump on the mill? I rarely see coolant feed being used unless it is on a CNC machine. Surely it would be preferable to stinky RTD?
Hi Bruce, love the videos. Do you do cash jobs? I have an old Howard Rotary Hoe that needs two 34 tooth spur gears made. If you're interested, please let me know.
I enjoy and learn from a lot of the TH-cam machinists I watch but it is especially valuable to see real world applications like your contributions. Thank you.
I'm trying to get my shop set up just to cut hard to find gears. Started when I bought a used 20" drill press , the table gear was gone to buy one the price was more then I paid for the press. With the power feed I wanted on it so I'm making my own eventually.
In my observation while cutting some gears, the cutter doesn't take a full depth of cut on every tooth. It's progressive, so each tooth cuts a little more than the last. So until you're cutting the full depth of the tooth there's only partial engagement of the cutting teeth.
Pete Brubaker Thanks, I've been reading and asked a friend who's got more experience. At first I thought it was a problem with lash in the mill itself but it's caused by the spacing of the cutters teeth loading and unloading the machine, a fine tooth cutter (not possible making heavy wide cuts) would possibly have multiple teeth engaged in the material with not as much noise.

John Thanks for the shout out I definitely will follow up with a second video. The gears are with a colleague wire cutting the keyways.
That gear looks absolutely perfect. Can't wait until I learn how to do that.
Bruce, Great video as always.
Good job Bruce.
Those arbors sure do seem to always have a lot of run out. I find myself oftentimes having to tweak one to get them to run nice.

Nice. Hope the one I get to do soon is as good.. :-)
Colin thanks, go for it, don't hesitate to drop a line if you need some guidance

Mate yes I do, give me a buzz on 0418955648 or email brucegetterout@gmail.com
Love the Howard Rotary Hoes, we had quite a few in our hire service in Colac when we lived there. Good Aussie design.
Thanks mate, I sent you an email.
is that anatoly from the big vases?
Not sure about Vases. Anatoly Burdeinyi From the Ukraine
Yeah, from Ukraine
It's me ;)

Can we cut 40 teeth gear using 135 to rack gear cutter??
I'm trying to get my shop set up just to cut hard to find gears. Started when I bought a used 20" drill press , the table gear was gone to buy one the price was more then I paid for the press. With the power feed I wanted on it so I'm making my own eventually.
Nice video/discussion/build
Very well done and good explanations. Thank you
good to see you,thanks for the interesting video .
Do you make gears for other people?
nice cut gear! thanks for sharing.
Nice job. Question; why so much noise from the backgear? Or is it normal until the load forces out the clearance in the drive gearing?
In my observation while cutting some gears, the cutter doesn't take a full depth of cut on every tooth. It's progressive, so each tooth cuts a little more than the last. So until you're cutting the full depth of the tooth there's only partial engagement of the cutting teeth.
Normal when doing it with a turret Mill from my experience, just the nature of the cutting geometry.
Bruce Whitham Thanks, since I saw the video I've been reading about gear cutting and understand better.

What grade steel are you using ?
I mentioned it at the beginning 1030.
Good job, I would like to see a breakdown of the arbor and tail stock assembly.
