Couple more items today. I am tired of Jerry rigging extensions and filler pieces to my tail stock when working with large tubing or pipe etc., and praying that it doesn't come loose. 
So if finally picked up a bull nose live center.
The other thing that has given me heartburn over the years is the set of small expandable arbors that I find to be mostly useless.

I say that because there is quite a gap between sizes, and it never fails that the size I need is always between two of the arbors. The set screw in the end only expands THAT END of the arbor, and unless it is a tight fit to the ID of your part to begin with you are spitting into the wind.
So the BBT delivered the solution to that problem today as well. Tapered arbors with 2 different size expanding sleeves per arbor, giving a size range of 1/2 inch to 2 inches and adjustable to within 0.001". No more wrapping the small arbors with tape, or making shims, or made to fit arbors.
