Gunsmithing / Re: Measuring mainspring strength

Thanks Coffinmaker. I received a response from Mike Brackett about how he does it(uses trigger pull gauge after hammer is brought to half cock. Hook gauge behind hammer face. When hammer moves record numbers).
My testing is to satisfy me as to why, some of my Colt style percussion guns will still occasionally suck caps despite:
arbor length correction
Slix Shot nipples
polished hammer face and safety notch
polished internals
One or two of my problem guns have responded to a heavier mainspring which cut down the problem significantly. I have no intention of installing a "cap rake". I feel the real problem is the darn caps. The thin construction material of caps combined with hotter caps along with generally lighter factory mainsprings has created this "perfect storm" of cap sucking, at least in my opinion. Having the opportunity to examine several original Colts, both SAA and percussion, I've noted a much heavier mainspring in all of them. Even though I am actively involved in SASS and enjoy a smooth, light action as much as the next person, if I have to go to a somewhat heavier mainspring in my percussion pistols in order to avoid problems, so be it. Besides, all this testing gives me an excuse to shoot more!

Well Ok, a couple of thoughts.  First thought, Trigger pull only measures trigger pull.  A poorly fit trigger can have a heavier "pull" than a well fit trigger, regardless of Main Spring.

One would have to build a jig to hold ALL subject Main Springs in a like position, then connect them to a gauge that measures the amount of "pull" required to move the action end a measured amount of deflection.  Then one would have to measure the effect of "stacking" (increased pull) over the full deflection of the spring.  Once documented, one would have to insure there was absolutely NO drag in the moving parts of the subject test action.

The results, as applied to the reaction of Percussion Caps, would then be skewed by the differentiation of material used by the manufacturers of differing cap brands.  Also skewed by the differing types/amounts of explosive material and thickness of sealant, also skewed by specific lot numbers of the various manufacturers.

The same variations would also be observed in various Main Springs, by manufacturer, based on lot numbers (unknown) and varying dates of manufacture.

Considering ALL the variables and complications, I think the objective "Gee, That one feels different" is as definitive as it's going to get.  along with measuring the specific Brisbane of the various caps.  Also, the test subjects would all have to be tested on exactly the same set of nipples.  Yule also need to arrange for a High Speed High Frame Rate camera and a skilled operator with a concurrent trigger mechanism.

Have Fun!!

Morning y'all.
Coffee and tea are hot.

2" so far.

'Tis 21 and light flurries. "Light snow in the morning  then a chance of light snow in the afternoon. Snow accumulation of 1 to 2 inches. Highs in the middle 30s. East wind 5 to 10 mph shifting to the northeast in the afternoon. Chance of snow near 100 percent."

What particular sight are you looking for?  1873?  1879?  (And yes, there are some variations in the main models of sights.)

Boy, time has sure flown by, the thread is near 5 years old.  :o

I wanted to recall the time frame of a purchased piece VS another, as to which order one came before the other  ???

All original sight bases are interchangeable.

Any Trapdoor with slotted screws has had its sight changed - factory installation used a blind screw head.

If you're going to do this, the original's base will have a 'C' on its side - even the repros will - and original 'C' marked rear sights are difficult to find - often exceeding the cost of the Carbine itself, when one's restoring a nicer one.

Scouts Out!
