Excellent source of pillow blocks:

I ordered 1/2" units for my drilling station and 3/4" for the CNC machine.
These units also have 2 small screws to hold the long screw in place, no
need to 'sandwich' the inner bearing runner with 2 bolts (like I thought I'd
have to do so now I've got extra bolts to go along with my loose screw :D
)
I would have taken smaller blocks for the driller, but they only have 1/2",
3/4" and 1" sizes. Since I already had 1/2" screws on hand and just got
3/4" screws today, my choices were easy. I can't get anything at a better
price locally anyways.
I also ordered my precision rods and bearings at VXD (forgot if I mentionned
their site already, I expect a $100 commission on each sale I generate from
this group :D yeah right...).

Just got my hands on 3/4" 10TPI long screws today for the CNC, and I have my
eye on 3/4" pillow blocks (more to come on that).
