Lathe Tailstock alignent

At the end of last season I noticed I was getting a measurable taper on some of my Grizzly G4003 lathe turnings. I put an Edge Technology tailstock alignment bar on my Christmas wish list and Santa was good to me! Now that the weather is nicer and there is actually some free space to work in the garage I decided to inspect my lathe tailstock with the edge technology tailstock alignment bar.

The thing works like a charm and paired extremely well with my 3d printer dial indicator for my quick change tool post (QCTP). It’s almost too easy.

Sure enough the measurements revealed the tailstock was .004” out of alignment.

After a few more mods to the tailstock I was able to get it within .001” alignment in short order.
