Hello all!!

I hijacked another thread in an effort to identify a newly acquired behemoth of a dividing head and it’s accessories.

Thanks to my best friend Gerrit we’ve determined that it is made in Sweden by SAJO.

I have scoured the internet looking for a manual, a manual seller, any information at all and have come up empty handed.

I am asking you all to please let me know if you find any information, a stray manual, an obscure PDF, or any information that I may be able to use to better understand how to use it (and its differential gears).

Too, as it weighs SO much, I would like to have it’s specifications and model number. Any help is appreciated!

So far I know this. It is a SAJO indexing head, with tail stock, support, 3 jaw chuck, 2 dividing plates, Spur centre and a pile of gears and banjos. It appears as though it has a MT4 taper in it as well. Weight is approximately 90 lbs.

Best regards all.

Derek.

Looks like something may be here but not free.

Thanks! That was the only literature that I could find and I think that it is just a catalogue, and not really much beyond some pics. I will reach out however.

Cheers.

The info on dividing including differential and spiral cutting would be the same as most any other dividing head, and can be found in Machinery's handbook, Cincinnati Milling book or Brown & Sharpe book on milling and milling machines, this, so long as the dividing head has a 40:1 ratio, as most all do, except a few that are 5:1.
 
To accomplish differential indexing, you would need another headstock center that extends out the back of the spindle to allow mounting of gears there to mesh with the dividing plate input drive shaft.
 
There are banjos, gears and another center support included in the lot. I just don’t know how it is all supposed to go together. Too, it turns out that it is an MT5, not 4 as I had thought. And I removed the spur center which revealed the threaded portion so now I have a 7 1/2” 3 jaw attached and I’m guessing an all up weight of about 150lbs.
