Got really lucky on an ebay find. It had the "make an offer" option so I did! Kurt 3600V that was a new/open box and had a few dings & a little bit of fingerprint rust spots; all of which were in unimportant places. Cleaned/stoned the vise and mill table, and checked tram on the mill, which hadn't been done since last winter. Mill held really well. Hadn't moved in the Y axis at all, and the X had creeped a couple of tenths or so. Tweaked it back to dead on, and mounted the vise. Sweeping the vise showed what all the hype is about when it comes to Kurt vises. Dialed in the stationary jaw with a half thou Interapid, and then opened the jaws to expose as much of the vise bed rails as possible. Swept them from side to side and down the length of both bed rails. Never more than a needles width of movement. The flatness and perpendicularity of the fixed jaw/bed is amazing. On the lookout for a twin, but I doubt I'll be able to steal two in a row! Keeping an eye on Kurts "Scratch and Dent" page, but the 3600V's have been out of stock for some time.
