Unimat 3 dividing head

I've managed to get hold of a dividing head for my Unimat 3. I already have one, designed for use with the DB/SL and seen here, which could be used with the U3, but this one has certain advantages for me.
Note that the body has a separate indexing plate, which is held in place by the chuck when fitted;

These plates come in 4 different hole spacings; 24, 30, 36 and 40. Mine is a 24 hole plate, perfectly adequate for my needs. The front of the plate is marked in degrees, and the holes are on the rear;

There's a pin which locates in the plate, on the top left of the first photo, which can be withdrawn with the knob on the back seen top left in the above photo.

Here it is bolted down to the saddle, ready for drilling radial holes in the end of a length of brass bar;

And set up for milling flats etc.;

Note the locking knob on the back;

One side of the unit is shaped to clamp directly onto the lathe bed;

Note that the milling post is now clamped to the saddle. This means that the cutter is moved over the job, rather than the job being moved past the cutter.

Set up like this the dividing head matches the machine's centreline, meaning that the tailstock can be used to support longer work;

To use the milling post with this set-up the milling post needs to be bolted to the saddle, but spaced further away towards the rear. Emco make a mounting bridge for such work, but the milling table can be used to support the milling column instead;

The above is an extreme example, but it should give the basic idea.

The spindle nose is threaded M14, meaning that any chuck, collet chuck, or faceplate designed for the Unimat 3 will fit, which means that I can use a collet chuck rather than a 3 jaw for holding work, which I would prefer. The SL version needs a chuck with a separate back plate, which is a pain as aftermarket chucks without a back plate cannot be used.

All of the above photos are of course posed, and the motor has been removed for clarity.
