Tom, thanks for the message. I think you did a very good presentation on how the system works, but it requires going through the math to gain a total understanding of what is going on. I look forward to your next video.
Thank you for your input on the gear system you are setting up, also thanks for the math used in the design. Without the math there would be no understanding of the system. To be honest I am still trying to get my head wrapped around the whole interaction. The differential is fairly simple, but understanding how to use it in practice is not straight forward. Adding the 90 to 1 table makes it a little harder. I think you have done a great job so far both in the calculations and machining. I look forward to your future videos.
Thanks, John! I’ll have a video soon that shows the finished system. I completely agree that the 90:1 makes things harder, but the overall math is the same even if it were 8:1. My next project will be to build a 20:1 or 40:1 work spindle, but that’s a ways off yet.
This was hard for me to understand, too, but in the end I realized that I was making it harder than it really was. I suspect I’m not explaining it well enough.
Hi Tom - what determines your machine constant Km? I'm watching your entire series, it's very interesting, especially how the differential works. Thanks for making these videos, much appreciated. One thing - the background music during the "math lesson" was quite distracting, would much rather just hear your explanation by itself. :) Again thanks!
Sorry about the music…I can probably edit that out and repost. The machine constant Km is the ratio between the index train output and the work axis. In my case the gear ratio of the rotary table was 90:1…that’s the machine constant for my machine, later revised to 40:1. Km is just the fixed part of the overall ratio between the hob and the work.
Hi Tom, I'm enjoying your videos, as I will be picking up a universal mill later this week with a full dividing head and with a table that will rotate 45 degrees. I'm looking to start cutting gears. Your videos are a good primer. But, there is always a but, the overlay of music really takes away from the message. I personally think it would be better just with your dulcet tones, they are enough.
Hi, Bill! I’m very excited for you…it seems we share a similar affliction! I appreciate the feedback about the music..production values are pretty much a mystery to me. Anyway, I would be happy to hear about your progress from time to time. Good luck!
@@thomasstover6272 Thanks for your comments Tom. The mill is a bit of an odd ball really. An Ingers 2 which is Italian and not one I had heard of, but sort of a Deckel FP2 clone in some ways. Power everything INT40 tapers, but it comes with manufacturers slotting head, full driven dividing head, rotary table, 90° angle attachment for the vertical head, all horizontal components, the angle table and more, but it was ex college and has then been used every couple of months for 1 job by someone who is retiring, as am I, but I want it for my retirement workshop. Yes looking forward to picking it up on Wednesday.

I'm jealous of white envy!

No need for a repost, you already have plenty to do :) Thanks for the explanation about the Km

What type of machine are you getting? I’m thinking about adding to my collection…

@@billdoodson4232 Sounds like an excellent machine!
Very difficult math
It’s very possible that I’m not explaining it very well, but it’s really just integer fractions. It was hard for me to understand at first, too.
