I have a fairly good sized stash of parts and pieces in raw form, ....spooled up many years ago by some old duffer who was making several different sizes of Soulle tang sights.
Given the embarrasing list off to the port that the new recess evinces, it seemed that providing some windage adjustment just migh be in order
Once some O1 drill rod was threaded to the new 1/4-40 TPI
chosen the goody box was raided, and this widget counterbored slightly @ .250", than tapped 10-32"
Those of ya' owning Soulle replicas will likely recognize the raw stock chosen, crap there's a LOT of fooling around goes into building those lash ups !
Sight, bottomed out, that should be plenty low enough
Maxed out,....should be about right for a "40 Rod gun", ..if not, spooling up taller one will be short work, I can probably wring another .250" out of the clearance below without hanging it through the trigger plate
Horsing this barrel around from vise to vise is fatiguing,....everybody has to believe in something, I believe I'll have a beer, and put the day's tools away.
