|Whats a good method to measure the firing pin stick out as it relates to the breach face?|
The actual making of the tool will not be pictured here as it is fairly straight forward.
1/2" drill rod
1/4" drill rod
1/4" drill bit
Socket head set screw of your choice with offending tap and drill.
Lathe and necessary accouterments for the proper use thereof.
Taking your 1/2" drill rod, drill a 1/4" hole about 1" deep, take cutoff blade and part so you have a piece about 3/4" long or so, this dimension is not critical but do make sure both ends are faced. Deburr drilled hole as needed.. About 1/4" or so from one end drill and tap a hole into the side of the cylinder for your set screw.
Take your 1/4" drill rod and accurately measure and cut off a 1.000" piece making sure both ends are faced. It really can be any length you want it to be so long as its longer than the 1/2" stub you made earlier. It would save you time and math in the future though if you just took your time and made it a accurate 1.000" long.
|The best things are simple, I made two of these gauges in about 45 minutes.|

|Might look good side to side but what you can not tell is the instrument is badly tipped causing the reading to be misleading. (Photo by CP)|
|Here is our gauge in action, simply tighten the set screw and take measurement with the same dial calipers from before. Don't forget to subtract the 1.000".....|
