I know there have been many posts mentioning the duplicating of a arbor taper.
I was compiling and cropping pictures and video of the Peck drill and put together a short clip of measuring the taper of a JT-33 Drill arbor.
I figured it can go here in the how to-s as it relates to what the guys have been explaining in various threads.
Feel free to move it if I have the wrong place for it!
