After a lengtly and spirited “discussion” between Denster and me, I thought I might add some clarity to what I was trying to say. I was mainly focused on the original intent of the wedge screw, which, according to the patent that I posted (dated 1836) the wedge screw was to act as a depth set for the wedge. And, as I stated, I was only referring to original Colts when they were new. There’s no way you can apply the same mind set to an Italian repro – some will be as closely machined as the originals, most won’t be. But that’s OK – I like the Italian repros just the way they are.
Where we differed (mostly) was in the meaning of the paragraph from the second patent that I posted. I read it one way, Denster read it another, but either way, the reason I posted it is was to show that when the guns wear, ie: abrasion on the barrel or cylinder, a deepening of the arbor hole or filing of the tip (either by normal wear, as I said, or purposely, as Denster said ) the wedge would once again come into play as an adjustment to pull everything in tightly, and, again, the wedge screw would act as a temper to the force of the wedge. I'll bet this is still a point of contention, but...
And that’s it from me – the wedge screw has more of a purpose than to hold the wedge in when the barrel is removed. I actually put a screw with an oversized head in my Pietta 1860 .44 and it did act as a depth set for the wedge and made the barrel/frame connection tight, as it is on my original 1851 .36 with the oversized wedge screw.
I'm guessing that Denster is more mechanically inclined than I, but I read the patent and applied it to my Pietta and it works. If anyone else has an original Colt, check the head on the wedge screw - I'm curious if it is oversized as it is on mine.
OK, I’m putting my helmet back on so let me have it.
