Henry Lever Action Rifles

The Henry Repeating Arms Company makes a series of lever action rifles in various calibers.

gunsmithing note(s):

      • When disassembling/assembling, the magazine tube hanger (near the muzzle) should be drifted by a non-marring punch that has been shaped to fit in the dip below the dovetail and the start of the ring. This is the only way I have found to do this that does not crack or break the edges of the dovetail on the hanger.

&

Colt uses an ‘&’ as an action mark to indicate that a revolver had been returned for factory repair or refinishing.

Random Knowledge: Marlin 336 Firing Pins

Marlin 336 rifles have two part firing pins. The two parts are the firing pin, front and firing pin. rear. There is an old style and a new style firing pin, front. The dividing line for which style firing pin, front a gun takes is the year of manufacture. Guns manufactured in 1984 and after take the new style firing pin, front. Those made in 1983 and before take the old style firing pin, front.

Random Knowledge: Brown Bess Frizzen

A recent client speculated that the frizzen of his Brown Bess flintlock musket was too hard. The issue is not enough spark. Thus, if the frizzen is too hard it would not be effected by the flint and diminshed sparking would be the result.

I made a call to the folks that know everything muzzleloader (Track of the Wolf, http://www.trackofthewolf.com/,763-633-2500), and found that the frizzen of a Brown Bess flintlock musket should be 62-64 HRC (Hardness Rockwell C Scale).

The next step is to test the hardness and see if it is within range.

What is a Gunsmith Kink?

After we posted our first gunsmith kink yesterday, someone asked, “What is a gunsmith kink?”

If you are not familiar with the term “kink” used in this manner, it refers to “a clever unusual way of doing something.” Thus, a Gunsmith Kink is a shop short cut, tip, or trick that that improves quality, makes a given process easier, etc.

They are mostly small things, or unique tools that that typically come from experience or have been handed down from one gunsmith to another.

We post one here from time to time. Watch for the category “kink.”
