Sherline Lathe - Tail stock Alignment

I had not checked the tail stock alignment in a while and found that it was running very low; about 0.010"!

This is how I align the spindle and the tail stock and found the low position. 

I started by using my feeler gages under the tail stock until I found the right answer.

I have some shim stock so I added them to the bottom of the tail stock and put a 4-40 screw to hold it in place.

For the other two axis I rely on the gage pin fitting into the taper pin.
