Re: Interesting Ebay auction showing production techniques ?
Its a shame that these barrel blanks were not more random in position so as to expose the breach end and the sight end of the blanks so that we could determine if they had been rifled and chambered .
The normal procedure for barrel making for "Long Guns" is most often , drill , ream , rifle ,and straighten the rifled bore ,then turn the outside diameter to precise concentricity with the finish rifled bore . this is done prior to chamber reaming , turning and threading the breach end and before finish turning the exterior prior to milling the sight block on the muzzle end .
From what I see this appears to be the proceedures followed on these blanks in the photo .
Considering WW-1 Technology I wouls estimate about One hour and a half per blank at this stage , Plus about three fourths hour more to finish the machining of each blank .
Considering WW-2 Technology I wouls estimate about twenty to thirty minutes total for each finish machined barrel .
Today less than ten minutes .
If one chooses to differ on these time estimates I will bend to pressure as I have not locked a turret head collet for thirty years .
