I recently added an 8x30" vertical knee mill to the workshop. While primarily a metalworking machine, it's a great deal more useful than a standard floor standing drill press in a footprint that's not all that much bigger.
I've used it for a few projects thus far; primarily to cut slots in the metal tubing for the table bases to allow for table top expansion. The DRO is really handy to have for precision and repeatability. I threw together a crude tabletop with fence that clamps in the mill's vise, allowing for easy transition between metal and wood projects. Plan to make a nicer one with t-track, stops, and clamps.
I'm envisioning it's use for mortising, perhaps tenons. Who else has one and what are you using it for? Any suggestions on endmills for use in woods? The mill has variable speed ability, goes from ~10 to 2000rpm and an R-8 spindle.
