Fitting & machining of bracket pads blanks on a No#4

[BrianLara400*]

Hi everyone,
currently have a few projects on the go @ the moment, one of which will be something like an L42 when complete.
I wasn't game to run the risk of getting repro pre-machined pads with insufficient material left to allow proper collimation - so I made my own blanks and will go about the H&H method of installing the pads and then machining the mating features, insitu relative to the bore axis.





I know the H&H front pad blanks, wouldn't have been piloted - however in my instance it became necessary so as to give me reference point to dial indicate off when it was flipped over to machine the backside. The pilot hole is well undersize that required for 1/4 BSF











I've got a few questions though;

#Does anyone know where I'd find a shell mill .600" in Dia x .370 inside diameter to machine the spigot with? Had considered using the boring head on the milling machine, however there's very tight space limitations to OD turn the spigot which would call for an absolutely miniscule boring bar. So am thinking that plunging the shell mill as per the H&H method is the way to go, its just finding one which is proving difficult.



#Also I've had a good look at the drawings in the Knowledge Library and have a mental picture of how all the mating features of the pads & brackets should come together. Just wanting to know if my interpretation of those drawings is correct (see below v)




Any info would be most appreciated
Thanks

Also a few pics of the rsaf enfield mag fitted to the action. In this instance it was necessary to machine the body to clear the rear feed lips (I've read sometimes it isn't required)
