Is there such a thing as a Hammer impact guage?

[Blueboar]

A trigger pull guage can tell us how heavy the trigger is.  Is there a guage that can provide ft*lbs or joules of energy in a hammer fall?

We clean up and polish things to make them work butter.  It would be nice to be able to measure the hammer as it is a key factor of reliability.

Yep, it's at the Fairground.

When the hammer falls and the catridge goes BANG you have the proper impact.

Nearest quick/dirty way I'd try is to find/make a aluminum rod the right diameter to fit down in the barrel and long enough to stick out of the barrel maybe an inch.  Then attach a yard stick to the wall/bench.  Then hold the pistol with the muzzle vertical and lined up with the yard stick with the hammer cocked.  Place the aluminum rod in the barrel, pulled the trigger and watch the aluminum rod with the tape measure in the back ground to see how high, in inches the aluminum rod rises.

Not a lbs of force measurement, but you could make mods to the pistol, repeat the test and measure the improvement in how high the rod rises up the yard stick.  Quick/easy estimation.

Genius,  thanks.  I like that idea.  It is not digital but it is data. And would be easy to do.

Experiment with a pencil with an eraser as a rod in the bore setup.  If the rod is too small, it will sit off center in the bore and the firing pin may not hit it well.  If the rod is too large in diameter, it will contact the extractor and not move freely when the firing pin hits it.  Some extractors sit pretty far in towards the firing pin when there is no casing in the chamber to hold it out. 

For example, a #2 yellow pencil with a flat squared off eraser will work in most 9mm pistols, but may be too small to work consistently in a .45.  An aluminum or brass rod with a squared smooth end should work well, and could even be notched for extractor clearance if needed. 

The "projectile" method actually works quite well on centerfires, especially when comparing a known good gun with a freshly modified or troublesome one.  For rimfires, a spent casing rotated to a fresh impact area to see a fresh indentation from the firing pin is good enough for an indication.

This method has been around a long time to test the safe functionality of decockers especially older models. It was the first test I did on my CZ52.
