Yes, I have had the barrel in the lathe just to check the fit.
I will have to shim the barrel at the back of the lathe spindle. I figure to make the shims from brass stock.
Thanks for the response.
This present sight is not dovetailed to the barrel and I am fairly certain I will apply the new sight the same way.
I am seeking a foolproof way of locating the new sight in proper alignment.
Any advice is much appreciated.
