Thanks, Greg! There’s still a few things to make, and I’ve made enough gears that the stuff I made first is starting to wear out. Happy to answer any questions… I made my first visit to HGR in Euclid, and came with an old Van Norton mill a few weeks back. That’s quite a place.
If you made a few videos just showing setup for a few different examples like you did here, it would still be very interesting and informative. Incredible. I must see more!
Thank you for sharing! I have a Kearney & Trecker 2K with the low lead setup to make helical gears, seeing you run through the math and process has helped me understand more of what goes into helical gears. Thank you.
Glad to see that the project is almost done. It was a fun adventure watching the progress. Can't wait for the next one. I'll be waiting intently. As always, thanks for sharing.
Gday Tom, this has been a fantastic series to follow and personally I’ve throughly enjoyed watching, very keen to see what the next adventure brings, cheers
Том, благодарю вас за подробности, я пользовался субтитрами и переводчиком. Спасибо за потраченное время на сьемку вашей работы и монтаж видеоматериала. Я знаю, это занимает много времени и сил. Хочу пожелать успеха в вашей работе. С уважением, Владислав.
What a cracking little series Tom. Its been great watching progress as you have gone along. I know quite a bit more about cutting gears than I did before, but still find it a black art subject. Looking forward to what you do next. All the best from the UK.
I wanted to make a differential in order to get a division by a problematic number of teeth with a standard set of gears. But I ran into such a problem: the compensating kinematic branch requires additional gears! I came to the conclusion that if you make a lot of gears to the transmission, you don't need a differential! It's not worth the candle.
It’s true that if you have a gear with a prime number of teeth, you can make that gear or any multiple of that tooth number. The division by differential setup on my machine only requires even-numbered gears to make any other gear, even primes. You can make any even numbered gear with a simple index train, then apply the differential with the evens in the kinematic branch to make the primes. Worth it for me, but effort is free for me, and knowledge is gold!
Next? Internal gear making, .... next rabbit hole. I did not watch all the videos, but did you have a go at fly-cutting worm wheels with a single tooth cutter? (my book here says that it has to be done with tangential infeed)
That’s true for a fly cutter, but the only worm wheels I have cut have been with a hob. I didn’t really consider single point, but I’ll do that sometime when I need an oddball pitch. The trick for me would be getting the helix angle. If I swing the table, feeding in the Y direction would be skew to the work. I think I’d have to skew the spindle, like LSCAD. A related problem is threadmilling on a horizontal mill, which I’d like to try. Internal gears are out there for me, but I have other things that I have to do first. I’m working on taking the hobbing machine to +/-45 deg helix angle…my crude index drive needs upgrading. Thanks for your interest!
😂 it’s not that I hate stepper motors and programming…it more that I remembered that I love making gears and it seemed a shame not to make a s-load of them!

Thanks for taking the time to film your work and explaining it all :)
Thanks…hopefully the production values will improve with time!
Brilliant work, Tom. I am glad you introduced yourself on the HM forum! Now I need to go back and binge watch everything!

You can absolutely do this! Have fun!

Thanks, Matty! The next adventure is just around the corner! This stuff keeps me young!

Sorry…can’t translate on TH-cam…
Your videos are very good! Just subscribed…
Afraid I can’t translate, but thanks for the comment!
I got the translation, Vladislav! You are very welcome..I appreciate your interest and your kind words! Best regards…Tom
What talent. I wish I understood 1/16 of the math you showed. Thanks for sharing Tom
Thanks for watching!
Just amazing the work you have done with gear hobbing I really enjoyed it. Thank you for sharing your knowledge.
Been a fun project…glad you enjoyed the videos!
Lovely job 👍
Thank you for explaining all the details
Thank you sir for your knowledge 😊
So nice of you!
Well done!
Thank you for the entertaining and informative videos.
Thanks for watching!
Very well done indeed.
Thanks!

Fantastic talent.
Many thanks
