Alignment cones 2x2.75 x30°

[Frank S]

I probably should place this under the http://www.homemadetools.net/forum/1...ring-bar-62986 thread but this thread has showed some interest
there are 5 short videos pertaining to this boring bar
THe alignment cones worked perfectly in assisting setting up the boring bar and stabilizing guide bearing as when I did the set up on the mill there were no adjustments required the quill freely went up and down a good sign that things are aligned up well after the work piece is clamped down I even allowed the quill to raise high enough to lift the boring bar out of the bottom bearing then returned it with no issues
