Have a bead on some linear rails that I'd like to do my cnc setup with. 8ft rails, round stock, for y, and 13 foot of the i believe thk styled (looks like and I sort off?) rails. From heavy duty manufacturing, sat outside for a bit during demo, and got some surface rust. I'm getting about 1200lb worth of steel that its based on, 2 13 foot rails, 2 8ft rails, a 8ft ball screw, and all the pillow blocks. probem is there is surface rust and stuff doesnt slide smooth on the round stock or at all on the other, but its just surface rust, steel wool can take it off. I'm curious if its salvageable and how much tolerance or if rebuilding the pillow blocks can take care of the little rust removed. I get it all for 850 delivered, just making sure i wont have regrets.
