This is a quick look at my home made dividing head, which I made to my own design.

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!

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... 🤗 😎👍☘🍺

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.
@MetalMachineShop2 ай бұрын
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/

Lovely design, and an elegantly edited video. High standards!

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
@MetalMachineShop7 ай бұрын
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.
@MetalMachineShop7 ай бұрын
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.

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.

do you have a spreadsheet with the angles you can with a certain gear arrangements or do you calculate it each time ?
@MetalMachineShop7 ай бұрын
I do have a spreadsheet yes, but it’s a bit trial and error for the gear train combinations.
@martin-vv9lfАй бұрын
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.

While it's a good idea to prepare your text in advance, you mustn't read it like a page in a book.
