I made one exactly like yours, with an ML7 spindle nose and using the ML7 gearbox banjo+gears well over 30 years ago and it has served my needs perfectly since... 🤗 😎👍☘🍺
It’s quite a complicated calculation involving trial and error for compound gear trains and depends on the gears you have available. There is a gear train calculator at this link www.amdengineer.com/resources/
I remember learning how to use an indexing head as an apprentice. This makes it super simple. So, from what I understand, the single gear is for equal teeth. Setting up the smaller gear train would replace the hole plate for unequal divisions?
This is a bit of a crib on the dividing head produced by Harold Hall in his book Dividing from the Workshop Practice Series #37. Its not identical but the similarity is there. Very well executed i must add. You've certainly given me an idea of a use for a used spindle from a super 7 lathe I have. Thanks for the ideas and the techniques used to generate the bearing blocks using line boring on the lathe itself. Duly stored for future use
Well spotted, yes I did draw inspiration from (i.e. crib) his design but I made mine with a much wide and longer base as I thought his would not be stable or rigid enough.
Great Video. i like your clear and concise delivery. I've been contemplating making or buying a dividing head and your video sorts that question out in favor of making. I don't think I would have thought of line boring on the lathe to ensure it's on center for future lathe use - very good idea. If you do any more detail on this, I'd be most interested in the bearings - what kind of tolerance you achieved etc.
I made the bearings to fit the spindle, so a bit of trial and error, aiming for a shake-free running fit. I can work to tolerance of about 0.01mm on diameter on a good day. The clamp on the split bearing allows you to tighten it enough to eliminate any play. I wouldn’t worry about it too much as any slight shake is unlikely to result in measurable errors on the work in a home workshop setting.
I guess if you don't have the correct change gear for the dividing head you have to use the latter to make a change gear, but then you can also use the custom gear in the lathe for threading.
Very clever creation. Thanks for showing this!
Very very interesting video and many thanks. Jim from Australia.
That's a brilliant unit. It is so sublimely simple, and using the existing change gears is genius.
Using the change wheels was not my idea, but it does work well!
Brilliant!
Also, really love the no-nonsense delivery

Nice! Worth the effort making it then!

Lovely design, and an elegantly edited video. High standards!
Thanks for posting this! Just the idea I needed sir! God bless.
Glad you found it helpful!
Great design. A little discussion on how you calculated which of your change gears to use to get various degrees of rotation would be very helpful.

Nice work . thanks for sharing .

An elegant solution!
I'm in admiration. I have the machines, hopefully one day I can achieve a skill level which allows me to machine like this.
Nice job 👍…
Pure genius!

WELL DONE!
Beautiful work!
This is a very nice bit of kit. Nice job
👍 ! Very nice !
simple but very effective something I will consider making for my workshop. Also easier on the pocket
Well done! 👍👍
That is very good. 👍
Great idea👍

Nice job.
Great concept.
Thanks for sharing.
I just subscribed to your channel.
Have a good day.
Thanks and welcome!
I like the design. Something that I can make.
Very clever. You have a great talent.
Thank you very much!
Very nice mind

Nice, two plunger mechanism's and you could use damaged gears without losing your point of index. You have the second slot waiting in your banjo.
SENSACIONAL!
👍👍👍
do you have a spreadsheet with the angles you can with a certain gear arrangements or do you calculate it each time ?
I do have a spreadsheet yes, but it’s a bit trial and error for the gear train combinations.
I really like it. I wish we could get some drawings for it with dimensions.
I could look at publishing drawings if there is demand.
@@MetalMachineShop count me in please.
Thanks
проще делительную головку уже не придумать. это самый простой вариант
No need to make it more complicated!
@@MetalMachineShop я обязательно себе такую сделаю
@@user-hc2bm9bj7q good luck, it’s a very useful tool!
Is not a dividing head, is a straight indexing fixture
great ideaIs .. it possible to make a gear with 23 teeth without using the number 23 or its multiples?
Either use a 23 tooth gear to start with or a 46 tooth gear, etc.
Please be advised that your thumb nail has a red line under it as if it was watched before.
I almost passed your video thinking I already watched it.
Oh - thank you for telling me, I’ll look into it,
While it's a good idea to prepare your text in advance, you mustn't read it like a page in a book.
Yes, you are right!
