I bought a B&S #2 Dividing Head off eBay. Looking forward to going through it & putting it to use!

Yeah, You got the one with the jack shaft for differential indexing. Now to find the gears to go with it...
Nice find, especially with the 3-jaw chuck that is on it.
 
Definitely a project. Haven't begun to digest the manual just yet, but envision making divider wheels & gears as needed. Should be fun!

I have one just like it for my #2 Brown & Sharpe universal mill; I have all the gear train for differential indexing, which I have used, and also to cut spirals, and have done that numerous times also, also have the short lead attachment for it, which allows cutting spirals (I think) 10 times shorter, like threads, for instance.

You might just become my new best friend for reference info! At some point I will be very interested in learning what all the stack of gears is used for & where they fit. Are they for the power feed off your mill for spiral cuts only?
 
The gears that come with the machine for the dividing head are used both to cut spirals and gear for divisions not possible with just the set of plates that come with the dividing head, such as prime numbers, such as 127, the gear needed for a lathe with English lead screw in order to cut metric threads; the extra set of change gears with the short lead attachment is used to cut short leads, shorter than can be cut with the regular set of change gears that comes with a universal milling machine; the attachment is also used to reduce table feeds for such as cutting shapes with the fly cutter with only one cutting edge.
You need to find a copy of Brown & Sharpe's "Practical Treatise on Milling and Milling Machines" It gives info on nearly everything pertaining to their milling machines, including gearing for spirals, dividing both plain and differential, and nearly anything you could imagine, including engraving divisions on special scales and rules and typical setups of their machines for many operations.

Thanks John! Just got a copy of the book you suggested. So easy these days. This is just the sort of reading I enjoy. Thanks again!!
 
I have several editions of it; bought the first on when I was in apprenticeship, as it was one of the required reference books in out apprentice classes; note the original universal milling machine pictured in the front section of the book; when I visited the factory in North Kingston it (the original first universal machine built) was next to the receptionist's desk!
My mill, built in 1943 is just like the one illustrated on page 14; previously, when I started my own shop in 1973, I had one just like the one on page 9, built about 1906.
 
I found a slotted sleeve , which goes on a tapered mandrel to hold items to turn on a lathe. I don't think the new what it was the had it paired up with a morse taper reducer. They wanted $10.00 and $3.99 shipping. Made an offer of $6.01 they accepted so ill need to make a tapered mandrel and polish it up . Ill run it on centers and lathe dog drive I want a good one. Those set ups run about $85.00 I got lucky
