The other week, I noticed the work try to climb the tool, so I removed the chuck and checked. Close to .005" play in the front and .004" in the rear. I gave the bearing cap bolts a quick tighten and got the play back to the .001" mark.
I'm wondering if the bolts have loosened with use or the shims have compressed a little?
I to found and corrected a problem yesterday. Being new to machining, every day I try something new as I get braver. Yesterday I realigned my tail stock for the first time. Used a technique shown by Tublacane where he used a wooden disk, mounted in the chuck, to hold a dial indicator which he rotated 180 degrees around the tail shaft to find the amount of error. My tailshaft was out .020" and was quickly corrected. What a simple way to measure and correct the error. Just like setting the head on the milling machine accept in the horizontal position.
