Making new back sight

Hi All, When I got my Sharps up and shooting I cheated with the back sight, it`s the same one on my Hawken plains rifle that I got form Track of the wolf in the U S A. So it`s not right and the plans have the drawing for the correct one, just being lazy so I got stuck in and started carving out a new period correct sight. So From two lumps of steel with my normal back yard lathe milling it`s coming on.

Attachment 65931, Have to make the slider next.

This is some thing you don`t see very often, if you have a small lathe you will always have something big to try and do on it. It`s the same with a big lathe only the other way around. Here's my way of fly milling the sight slider with small fly cutter nice and slowly.Attachment 66247,
