so finally I get to stick my new project barrel ( Shilen sporter in 35 Whelen ) for a spiffy 1903 sporterized action ....... in the lathe and get ready to thread the chamber end ...
maybe I better look at the original takeoff barrel first ... goofy coned breach and square threads ... geeeeze ...
so i cut a test barrel stub just to test for proof of my scheme ... hmmm .. mine don't look the same as the originals ... hmmm ..
hey, somebody screwed up the original barrel .. square threads are way too shallow ... square threads are supposed to be square !! ... minor diameter is same as width of thread ... what thu ?? ...
these are 1.040 major and 0.999 minor ... ?? ... very shallow ... ok, check those neat original drawings we posted here a couple weeks ago ... oh no !!! ... it calls for the same shallow threads ...
ok, I will just go with the flow and dup the original, even the useless coned breech ...
********************
does anybody know if these shallow threads were used throughout the span of the 1903 life ?
**********************
kinda trivia ... maybe the weird threads came from the same design team as the funny coned breech ?
btw, that action is nearly dead on to the drawing specs ... I didn't even have to shave anything on the action ... it was quite square already ...
oh yeah, i had to epoxy a square bushing onto the barrel to get the original off the action ... first one that gave me that much trouble ... guess 110 years might do that ...
