Thanks Jim, for posting this,...
You and your Pop have seen the back story on the pieces and parts,...I'm just going to post that as written,...
....and every piece has a story, to boot !
I really LIKE barrel band sights but man, are they ever time consuming to build. The massive bore sizes look kinda [bleep] without em', and yet I did not want to go overboard here.
.....went digging through my plunder and came up with the parts and pieces needed to spool up a fine "2 piece" unit,.....although by the time I either TIG weld it or Silver Solder the pieces it WILL be a one piece part.
The "band" was turned off a chunk of .43 Spanish Barrel (circa 1880s) that was taken off a really decrepit old cut down Remington Roller that had the "machete V" in the buttstock,....so it probably rode with Pancho Villa's outfit. I got the rifle from a fellow who'd bribed it outta' Mexico, in any event. Nice Nickle steel in those old pelters, it machines well.
The Ramp was de-soldered / came off of an old Remington 721 in 30-06 That I bought for the action only, at Cashway's Pawn in Tucson, back in 1996 or '97. It had come out of a Police Auction, and apparently had been used in some sorta' crime in Nogales.
Yes, there is a gap between the Ramp and the barrel,...No, it won't be there when finished,...I've taken it as far as I want to go with the machine tools, and will hand file a mortise into the band so they dovetail together in good alignment. As noted, I haven't decided whether to TIG weld em' together, or go with High Temp Silver,....but am leaning toward the TIG
...I kinda' like the 3/8 dovetail in the ramp, it's a COMMON size, and easy to find in any variety of heights and bead styles.
PLEASE let me know if this front sight works for you.
All the best,
Greg
