The pics on ebay are of the work holding side ? Ya think this will fit
my 10" Logan ? Might save me buying a mill until I actually have room
for one ...

if its for an atlas then there will be a spot for a bolt to go through
it to a T-slot on the compound

Actually -- no. The compound is removed and this mounts in
place of the compound. On an Atlas lathe, it fits over a dovetailed
stud on which the compound rotates. On a SouthBend, the affixing is
somewhat different, thus the need for the adaptor which he mentioned
making (in the auction).

The compound is removed for at least two reasons:

1) Increased rigidity with the milling attachment mounted directly
to the cross-slide.

2) More vertical travel is possible than with the compound in
place, since the top of the compound is only an inch or so below
the centerline of the spindle, which is where the end mill will
be mounted.

if your logan uses a tslot on the compound as well (likely) just make
or purchase a T-nut to fit

Nope. For an Atlas, just slip it over the stud and tighten the
setscrews to close the angled clamps (which he also mentioned making) to
lock it in place. (BTW, I would suggest bronze or brass for the
clamp.)

For the South Bend, you turn a piece which fits into the hole
which the projection of the compound fits, and turn the upper part into
a dovetail matching what the compound of the Atlas would have. To be
honest, I'm not sure *how* the compound of a Logan fits to the
cross-slide, but since Snag has one, he should be able to determine
that.

My Clausing has the hole similar to that mentioned for the
SouthBend, with a circular T-slot surrounding it for the heads of the
bolts which clamp the compound to the cross-slide.

Enjoy,
DoN.

My compound mounts on a stud (hole? can't recall , but makes a minimal
difference) with two bolts in circular T-slots . Sounds like the mount
would be fairly easy to make .
I'd still rather have room for a real mill ... alright , alright ,
I'll quit whining now .

Terry, you can buy a minimill for not much more than these milling
attachments usually ebay for. A minimill can do a lot of serious work
within a working envelope a little larger than a brick.
I have a nice mill-drill now, but I still use the minimill whenever
possible.
