- Second of a two part video about the dividing head. In this video we look at the diving head and how to perform direct, simple and angular indexing operations. As for all THATLAZYMACHINIST videos, this video is produced for novice , garage or beginner machinists. You can find all my videos as well as project drawings and course notes on my website THATLAZYMACHINIST.COM . Thanks for understanding that I am a professional toolmaker and teacher but I am not a professional video producer (and it shows). I produce these videos for fun as a little retirement project that lets me give back a little of what was passed on to me by so many amazing trades people most of whom, sadly, are no longer with us.

Thanks Marc. I Love your videos. Basic in depth knowledge of the subject that so many people need.
You may call yourself lazy but you are very thorough
wow really smart guy here, not lazy for sure,
Simply beautiful
enjoyed very much. always lots to learn
You're a superb teacher. This is a neat way of approaching the subject. If only we could give more than a single thumb up....
And I thought I knew indexing heads, then you showed how to set a dividing head using degrees. Way too KOOL, Dude your the MAN, THANKS.
Your right on in the way you taught this but some people still have problems understanding.
Another way to approach teaching this to someone might be to let them know that if you take the number of holes say using the 18 hole circle, that 18 X 40 = 720 and the divisions needed has to be able to divide into 720 and the results ""has to be a hole number"" or a different hole circle has to be selected. This is actually harder, but simpler for some people to understand.
Another thing that I figured out is the reason most hole circles on dividing plates are in odd numbers is because if you take any odd number and multiply it by an even number like 40 you wind up with an even number and even numbers can be divided to into equal parts.
The importance in this is the fact that using an odd number plate, divisions can be made to create both odd and even divisions. But if all the hole circles were in even numbers, then no odd number spaces could be made.
Excellent! I have struggled to understand my dividing head and these 2 videos have helped! I even made a favorite topic named understanding dividing head and then saved these two videos to that list!
Excellent, comme toujours !
Thanks Marc. I recently did a project that needed the dividing head. I have had very little experience using the dividing head and it presented me with some head scratching time. I wish I had seen this video before doing the project. Great explanation of the math involved.
Great job mr Marc same as the others you do thanks
If we don’t understand, change the student, because the tracher is the finest.
Marc 👍👍👍✌
Marc, thank you for these two videos. But, what are compound and differential indexing when using a dividing head? I've heard of them, but don't recall what they are and when they'd be used.
🙏🙏🙏🙏🙏🙏🙏🙏🙏👑God with you 👑
Hey narc can you make a lesson on compound gears and on helical gear cutting or beville gear??? Their is no videos on net or ar least an explanation of the system..... Thanks karl from malta
Great explanation. Is there a part 3 coming?
excellent explanation. Could you share the manual of that divisor
how is footstock aligned? i have a test bar but it is longer than the mandrel for the workpiece- if i use test bar and then have to move foot stock -then it would no longer be aligned?
Are you using a Cincinnati brand dividing head, the reason I am asking is because I have a pair of plates with holes on both sides like the one you are using
what does it 20 divisions mean ??? is that number of teeth??
