Small indexing head upgrade and fit out.

[steamer]

OK...so I have this wonderful little indexing head came into my possession....as some of you are aware.

Thought I'd post some of the work I'll be doing to bring her into the fold....so to speak.

This includes

New spindle.   ID     3C collet     OD    1 1/2-8 spindle nose identically matching my South Bend 9 lathe

Alter the  body to have the T slot tongue fit my Clausing 8520 mill

Build a tailstock to match the headstock.   This will be a fabricated "durabar" bar stock iron body and will copy the "Duclos" design in everything but the center height, which will match the indexing head.


Why?

I want to be able to use my 3C collet collection...quite ponderous....and be able to swap chucks from my Southbend into the mill
The indexing head by itself will be able to be gripped in the vise for more simplistic jobs like cutting hexes ect.

The other major use I see for it is crank shaft roughing in the mill with the crank shaft held between centers.

I'll need a 3C center with drive as well......

I ordered stock for the spindles....I have a ton of bar stock iron sitting around...so I'll get crackin on it shortly.

Oh and I'm looking forward to seeing what the old girl "Samantha Bell" will do with the spindles..after all my work to rebuild her.....

I have faith in her!!!

The 2" and 5/8" 1144SP round bars have shown up!    The 2" is big enough to get a Wallaby Crank out of as well!...

This weekend perhaps....

Looks like it could be a very handy tool Dave. I guess a fellow can never have enough of them.

OK Mr. Dividing Head.
I've been trying to figure out what this is and how it would be used. It came with my new dividing head. I think that it's some apparatus for dividing between centers given that the dead center is a perfect fit.
HELP!

Hi Stan,

 To me it seems you have got the carrier right. Just a grub screw (set screw) to clamp carrier to centre. My guess is that the four square objects with countersunk holes are tenons to locate the dividing head in a milling table T-slot. Nice piece of equipment, I recently made an indexer based on a Mini Lathe spindle.

Thank you. Got it.
We now return you to Dave's thread.

Got a start on roughing down the 2" stock to size.    It has to come down to 1.4995....so I have a way to go there, and then it needs to be drilled 5/8 through  6 3/8 deep...it'll be from both ends....

Then the spindle nose of my lathe will be duplicated, and the bore opened to 3C collet dimensions.

the  old spindle came out once I removed the 3 dowel pins holding eh index drum on.....it's a real simple device that's for sure....

Now we're talking. It looks like the old gal still has the touch . Are you going to single point or use a tap for the internal threads?  Tell everybody hey.

Cletus

[steamer]

The spindle nose threads will be single pointed.    1 1/2 -8      SB's spindle nose thread has a major diameter of 1.496, and a register diameter of 1.510"

All the inside diameters will be bored to size.
