Screw tips for powder horns

[olfuzzy]

I've noticed quite a few powder horns that people have made that have screw tips made of various materials and are beautiful. My question is, what do you use to cut the threads on the horn and tip ? Is it done with just your standard coarse tap and die ( if so, what thread ) or is there a special set just for this purpose ?
I've also seen a few, commercially made I believe, that also have the fill plug in the base threaded but it seems to be a different type of thread. What is used to cut these?

There's a couple of ways to do this of course, Please see the links;

A regular set of tap and dies works fine. Just go easy so you don't split or break the horn or plug material. I used a 1/4-20 die on the tine of an antler. First, file the tine down to the proper diameter for 1/4-20 die. Because the die won't cut the full length of the filed-down tine (it'll leave you 1/8" or so short), use a triangle file to finish the thread the rest of the way. My horn developed a hairline split as I tapped it, but I shaped and epoxied a piece of maple over it. Horn can be filled with homemade funnel, a 3/16" OD, 0.014 wall brass tube soldered on 0.025 brass sheet formed into truncated cone.

For filling plugs I use a standard 1/2 -13 tap with brass 1/2 13 plug . For the spout I use a 1/4 - 20 tap and a 15/64 tap drill. with a plain tapered wooden plug. the light threads will prevent the plug from falling out yet allow for easy removal with a 3/4 turn.

The part about being careful- YES. Horn is very easy to chip. The threads can end up not looking very good- work okay but all chipped out.

I find that a little super glue in the threads followed by a well waxed bolt will reenforce the threads in horn or wood.
