Ok, now with new pictures showing it installed alongside it's baby mill brother.
And, yes, I realize I put the Kreg table stretcher upside down. Not going to change it now!
For those with stiffness concerns, the tables are 1-1/2 thick glued up cabinet grade plywood and are screwed along the rear edges to either concrete or stud walls, and the stud wall is clad in 1/2 plywood, not drywall, for added stiffness.
Since the unit I bought was actually a freestanding model, I carried the mounting plates across to this setup, but left the legs and pan behind. The seller was wanting to use them for his wood lathe project and I've since bought some oversize baking pans to catch chips and drips. No plan for lubrication system (for now).
Despite it being in really good shape, I did discover the previous owner had packed the lead screw and worm with ordinary grease rather than the designated oil. Took quite a bit of time to clean that out without tearing down the entire unit. Will be returning to oil for lubrication, as per SB documentation.
Change gear cover is removed as the pin which carries it has worn loose in the casting (sags and drags on the spindle) and I will need to repair that, so it will run unguarded for a while.
