I have watched your series for quite a while. Your attention to detail, your tenacious nature and your single minded drive are to be admired. Thank you for taking the time to document your journey. I have thoroughly enjoyed the ride.
"I haven't figured out all the details on how to do this." I don't think many of us who have watched this series would even attempt to start this let alone figure out ANY of the details. Really impressed by the size of your shop, here in the UK I consider myself to be lucky to have 480sq/ft and a 3 phase electrical supply. Most guys manage with a 10 x 8 shed or less. A shop tour would be nice sometime.
I can appreciate all the work you did to get that gear train setup and working. However, I think you would have been better served with an encoder on the spindle and a servo drive on the rotary indexer. Take a look at Clearpath drives. You wouldn't even need to do any programming.
I started this journey with a digital system, and it worked, but I really struggled getting consistently good results. Then I started looking at building a mechanical hobber. This project has always been about trying to understand a complex machine well enough to build one that works, building skills and learning along the way. By the way, I think Clearpath drives are brilliant, and there are lots of good applications in projects I can imagine doing. Thanks for watching!
Gday Tom, well I’m absolutely fascinated at this work of art you have created, to see all this working at once and producing quality parts is a true credit to you Tom, this is something to be very proud of, I get excited about making a single spur gear, absolutely amazing job mate, I’m very keen to see what you create next mate, cheers
I just happened to stumble across this and boy am I glad I did. You have a machine that is very similar to the one I have and it looks like you have done all the customization that I am either doing or plan to do. So happy to see there is like minded people out there.❤
Damn Tom! I can’t think of the right words for that beautiful work you have done! I’m gonna watch it a few times I love it so much! Ever since I was a kid and started playing with RC cars I always loved gears. I considered attempting a similar project if I had a little more time. And as I said before the math to it all but I woulda figured it out. I love making gears! I’ve been trying to think of a smaller project I can do just to make a couple. But keep the videos coming!
I love the little jacks you made too. I haven’t even done those yet. In fact I haven’t used my machines really in a few months because I got a new puppy in my garage with me and I’m worried about him swallowing shavings. My last boy I didn’t really have to worry so much because he was older and well broken in. That’s what happens, your dog finally becomes perfect then you lose them. Yeah I had a pretty rough fall but I’m starting a new adventure and boy oh boy is it a lot of work starting over again
A wonderfully complicated project beautifully executed. You certainly overcame a lot of challenges in designing and building it. And looks like without using CAD, so even more impressive engineering talent. My only concern is that the C of G of the entire machine may be close to the tipping point on the one side. I noticed the machine wasn't bolted to the floor. I'd hate to see the whole machine tip over. But congratulations and well done.
Alas, my VN 24 does not have the Universal table. In looking at the running drive train shots, I couldn't help but wonder the name of the clock maker in Alice's adventure. Must have been Tom! How else could the white rabbit know he was late? I do have it on good authority that his license plate is ML8 ML8.
@@BROCKWOOD64 Well, that’s a first!😀 One gent wrote a haiku, and now I’m through the looking glass! Dead on, Brock! There is something noisily hypnotic about watching gears running, for sure! Glad you enjoyed it…and so you know, the new project will hob helical gears without need for a universal table.
Does the pivoting portion of your new differential get locked at a specific angle before cutting a gear? Or does it rotate as the table traverses through the cut? Would that rotation introduce an error? Fascinating to watch all the whirligigs whirl.
Yes. The differential gear loop must satisfy the equation 23=2C-B. If C=15 and B=7, this equation is true, for example. The differential ratio C/B=15/7, practical gear pairs would be 30/14, 45/21, 60/28…multiples, since 7 is prime. For my system, I would use C=22, B=21, and use 44/42 as the actual differential gearing. Hope this helps!
Ps…the choice for B is important, since that determines the rest of the index train. In my system I use B=20 for even gears, and B=21 for odd gears, which simplifies the rest of the train.
th-cam.com/video/C2NfHBB82QU/w-d-xo.html You explained why you went with mechanics and it is fun to see all these gears working together. But maybe someone is interested in the electrick. 🙂 As long as you do not want to hob worms 45° is quite O.K. I assume.

Thanks, Kevin! Hope you will stick around…there will be something new pretty soon!
Your a pleasure to watch . The educational value alone would dictate that I stay. The mere fact that I like it. necessitates I stay@@thomasstover6272
@@thomasstover6272We're all looking forward to seeing more of your excellent work Tom!
It's just beautiful! You are a true machinist!👍
Thanks! I enjoy what I do, but I learn a thousand new things every day!

Thanks, Bill! My shop is in a large barn on our property. I’m told there is a house on the property as well. Tour video in the works…

I was thinking the same thing.

Aside from the cleverness with the gears, I like your drip tray idea.
Thanks! Needs to be bigger…that coolant makes a mess! I put an old shop towel inside the box to filter out the chips…

“Work of art”. Thanks, Matty! Not sure what’s next, but I’m dead sure I’ll have fun doing it!

Welcome, Bill! I’m always happy to find kindred spirits!
Forgot to ask what kind of machine you have?

Keep the faith, Kenny! Just dive in and do it.

@@albertquestiaux2660 I’ve thought about tipping…I’ve actually tipped it the other way slightly, to get the coolant to drain correctly.🙄
WOW, so impressive
Wow. That is allot of gears. Nice work
Thanks 👍

It’s locked in position. It would introduce a phase error if it pivoted.
Try a cv goint
Your collection of milling machines is impressive.
Do you make the bevel gears yourself?
I made a set of 4 for the index differential. Very tedious…in the “fun one time” category. These I bought.
Great work.. Can I make a 23 tooth gear differentially without using the number 23 or its multiples?
Yes. The differential gear loop must satisfy the equation 23=2C-B. If C=15 and B=7, this equation is true, for example. The differential ratio C/B=15/7, practical gear pairs would be 30/14, 45/21, 60/28…multiples, since 7 is prime.

@andysmachines is a good place to start on a digital indexing system for gear hobbing.
