Down at the Old Mill

My son-in-law has got himself a Bridgeport mill that I think is older than me. He's excited to clean it up and has expressed an interest in doing something with a receiver. I would like to get him some tooling for it for his upcoming birthday, but I know bupkiss about machining or machinery, so I turn to the High Road for advice. All I know is the mill has an R8 taper.

Of course, I can always just ask what he needs, but that kind of spoils the surprise... Is this a dumb idea, or can I make a good guess at some tooling that would be useful to him and would fit in his new baby? I know I've seen some pretty amazing threads involving machining here. I'd say "don't worry about hurting my feelings," but I bet that's unnecessary.

Thanks for all the wisdom to come!
 
What size is the table? That will determine the size of some of the tooling. It has to be able to fit on the table and be clamped securely.

A good machinists vise for a start. Kurt is the benchmark brand - http://www.ebay.com/itm/KURT-6-VISE...590849?hash=item2ef176cec1:g:FFsAAOSwRS9Xf9XM . Some angle plates - http://www.ebay.com/itm/Slotted-Ang...967505?hash=item257bfcfd91:g:16YAAOSwTapV411y . If the mill did not come with one, a clamping kit similar to this - http://www.ebay.com/itm/58-Pc-Pro-S...925257?hash=item1c686af8c9:g:8zgAAOSwstxVMv4o . Those are just a few examples. Again, specific sizes are dependent on the size of the mill and its intended use. He will need end mills of various types as well.

The rest depends a bit on what kinds of things he wants to machine. For example he might need a boring bar.
 
Well, if you have the money, and/or can find a used one, an indexing head is just about the cat's meow for a vertical mill. That, plus a 5C collet holder and assortment of 5C collets should put the young feller in nirvana land (and in perpetual beholding to you!).
And, I bet that BBBBill really meant a boring head, instead of just a boring bar.
Better yet, a "boring-and-facing head"!
 
Thanks for the replies.

Turns out he got two vises (one missing a handle) along with it. I have ordered a clamping kit that will fit (assuming that one actually measures a t-slot at the top rather than the bottom!).

I think the indexing head is beyond my means for now, but the collet holder and collets seem affordable. The collet holder has to fit the R8 taper? Or am I misunderstanding that?
 
Oh, and not that it matters, but according to the serial number, it was built in 1944, so it's a LOT older than me. Well, some older...
 
Yes, boring head. Boring bars are for lathes.

The R8 collets are for the mill to hold the end mills. The 5C collets and holder are to hold round, square, and/or hex work pieces. Here's a basic model - http://www.ebay.com/itm/TTC-69-102-...864c4d82994286d04c9835&pid=100507&rk=1&rkt=1&

You clamp the collet holder to the table or to an angle plate (fixed or adjustable) to orient the work to the milling cutter.
 
There used to be both square and hex 5C collet holders, which, when used with a machinists vise (and a work stop) allow one to crudely index the workpiece (held in the 5C collet) for different operations. I say "crudely" as compared to an indexing head.
 
Also take the draw bar out the top of the spindle. Check the threads, that they're not worn or stripped. Collets won't do any good if the draw bar is screwed up. ;)

You may want to get the head model number and find an old parts list. 1944, hard to say what shape the belts would be in.

The best thing about an old Bridgeport, they can be rebuilt, and rebuilt, and rebuilt.....
