This one was inspired by the bottom horn on page 146 of Grinslade’s Powder Horns Documents Of History. The tip screws into the collar rather than the horn itself. There are about 45 pictures that go with this so I will make several posts out of it. Like I said, this way works for me, there are others or steps that don’t have to be taken.
The horn with the tip cut and drilled, ¼”.
The ¾" hole saw with a ¼” pilot
Drilling/making the spout were the collar will fit.
The result, the excess will be rasped/filed/scraped until it is gone. Then the shaping of the horn begins, from tip to base. Try and get the step at the spout even all around, the length can be trimmed later as the collar is fit.
This step is probably overkill but it does a couple of things, first it reduces the diameter of the spout to almost 9/16” which is the size hole that will be drilled in the collar, second if you use a little glue along with the pins to hold the collar on it will give you some tooth and it gives some practice in threading horn. As you can see they are rough, that is because I did not use a jig to keep things lined up, the dye is 5/8-11. Anyway…
Here I have a 9/16th hole in a board using it to test the fit all around the step.
These are some possibilities for the collar. Finished length will be about an inch to give an idea of starting size.
Drilling the ¼” hole so it can be mounted on a pen mandrel (PM).
On the PM, first step is to square it up and start rough shaping. It needs to come down to a size that will fit in the four jaw chuck.
