Today I took a perfectly good 5/16"-24 tap to the grinder and put a relief in it to help me clean out the table gib screw hole. I tapped, oiled, dug around in and finally got that hole cleaned out. I also cleaned the crap out of my bport table, literally. Yuck. I oiled it well to soak for another cleaning tomorrow. I determined how shy the table gib is and shimmed it. Hope tomorrow to put the leadscrew and table ends back in it (more cleaning on table ends too). I'll put the head stuff back on the ram and do some indicating against the table if I'm really lucky.
