Taylor, your install is 1st class...as usual! I have always pinned my Hawken entry thimbles, but on this last build I thought I would "follow" the drawing and as such the entry pipe is screwed on. I thought at the time this is way more work having to braze a pad on the back for the screw....does not seem 1850's logical. Funny I built the rife last year and am still thinking about the attachment method.
