tang width ?

[frenchman]

getting ready to make the entry tang. My barrel is a .36 cal with a slim forearm what should the width of that tang be and is there a way to measure this depending of the built that you are making 

[D. Taylor Sapergia]

Make the tang of your entry pipe the same width, or just a bit wider than the width of your pipe proper.  Make it to the same contour as the forearm.  Some originals are parallel, some taper - wider at the pipe, and some taper the other way.  There are no wrong answers.
