I've made up Something Similar, but using the lathe's topslide to get some vertical movement (around 5", cross-slide travels about 11"), don't have a pic of it all together (it gets stripped down for normal turning!), only the mock-ups, but it's based around a large angle plate which is bolted to the cross-slide T-slots and an adaptor disc (with a spigot the slide pivots on) to set the angle of the "vertical" travel. The angle plate has long slots, so it's possible to set it off at an angle if the need arises, just fiddly!
Mockup 1&2: 2 views of vice on topslide, paper template for adaptor, all sat on face of angle plate - the trash drill vice was for "proof of concept" and replaced by something Much Heftier since (sometimes a 4" tilting mill vice, if it's a complicated setup);
Mockup 3: view of angle plate on cross-slide, plate overhangs cross-slide by 1/4 - 1/2" for clearance behind the adaptor and "vertical slide";
Apalling drawing: the adaptor plate - central spigot and top edge are "clocked" for on-centre and parallel before the topslide goes on. I've no idea why the angle calibrations go right around the adaptor (in the drawing), as it will only pivot 45* each way... so I didn't cut 'em!
The angle plate came with my previous lathe, and didn't fit anywhere on it, but when mounted to this one the intersection of the slots is *dead on centre*... Weird, the way all the tooling with the old one didn't fit it, but fits its successor perfectly and replaces a lot of the missing bits!
This setup's good for light milling, adequate for slightly heavier work, but limited by the size of the installed vice and rigidity (as you'd expect). It's nice to be able to use the power cross-feed and its micrometer stops-and-trips to hold a dimension, though!

I already can see this guys got my way of thinking good job its called survival, like my SB steady rest
that started life as a common pipe vise which has the ingredients just had to tweet it; the brain is
a remarkable devise aint it. good work guy

I like it! You do have some vertical adjustment by using the slots in the vise for fine adjustment and the bolt holes for coarse adjustment. I'm stealing this one, thanks! A set of jack screws on the top plate of the vise, pushing on the top of the main support frame would make adjustment a piece of cake. Thank you for this.
