Milling on the lathe Vertical tslot table or vertical milling vise?

Since nobody has replied about the vertical table vs. vise, I'll comment. I've got a Palmgren milling slide with a slotted table instead of a vise, I've always regretted that. By the time you get a vise on the thing, you've got a whale of a lot of leverage on the compound. I replaced the lantern TP mounting forks on the milling attachment with a disk that fits the compound hole on the 9" S.B., it helped, but not a whole lot. Still a lot of leverage there, things moved while cutting. I made my own milling cutter holder for the headstock, cut off a large MT3-shanked drill, drilled and tapped the small end for a drawbar and bored a hole in the other for the cutter shank, secured with a setscrew. Still couldn't do keyways very well. Solved it by going with a Aamco shaper. I now have a small vertical mill for that stuff. The slotted vertical table was good in theory, being more flexible than a vise, I just couldn't get a solid setup that way.

I checked in with MLA and found out that for the atlas cross slide table i would need a mill to finish the casting.

It sort of created a Chicken and Egg situation

I'm looking for this kit because idont have a mill but i need a mill to make the kit work (And the cost of the local communit colleges machining project course is $400 for access to the machines and no teaching involved)

I could put the 400 towards a mill or towards > D>

I found a small but sturdy mill for $300

=================== You don't have to have a lathe milling adapter to do milling on the lathe. It just makes it a whole lot easier. You can get by with a right angle iron of the appropriate size bolted to the top of the cross slide, and the part to be milled clamped to the right angle iron. Problem will be in the set-up/adjustment. This will involve several hours with the dial indicator to get the face of the right angle iron exactly perpendicular to the spindle axis and then several hours to get the height and pitch of the part correctly clamped to the angle iron. Major PITA, but you only have to do this once. How do you think the first machinist made one?

I milled a block-style toolpost on my 9" Logan with no mill or milling attachment. I have also used a Phase II QC toolpost and holder as a small milling attachment. The toolbit clamping posts are you "vise" with built-in vertical screw adjustment. Works for small things.
