Steve: Recieved the nut today,already installed ,backlash now .004 with my new lead screw. Got to start saving my pennies to get the X and Y ways refinished ,Z is not bad at all. Get that done and the old gal will be in near new shape. Got lucky and found a new 6" riser for 1/3 of retail. Just the thing I needed to make good use of my rotab with mounted chuck. Again I can't thank you enough for the nut, I'm in your debt !
Thanks, John
