Another Style Of Screw Tip- How I do It Horn How To-
« on: January 31, 2011, 12:06:36 AM »
  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.

A problem, the tip is delaminating, see the light area on the right,  scrap this one and start another.

New blank

Squared up and turned to working size. Next is to drill a couple holes in it. A one for the spout on the horn to fit in and one that will be tapped for the tip.

Drilling a 9/16” hole in one end to about the depth of the mark on the bit.

The 9/16” hole, this will be fit on the spout on the horn.

This shows the 27/64” hole that will be tapped for a ½-13 thread. The hole is about ¾” deep. I apologize, I did not get a pic of this step.   

Here the hole is being tapped.

Shows the collar on the spout, 9/16th end.

Next is the tip, the basic set up is the same as it was for the collar. Here the tip has been rough turned and the portion that will be threaded reduced in size.

This shows the tip being threaded. I started it the same as I did the tip in the earlier tutorial using the jig made from two bolts.

Threaded but left long for fitting.

Here the tip and collar have been screwed together and put back on the PM. If everything is kept square during the taping and treading there will be little hand work to do except for trimming the threaded area of the tip to length and tapering the first few threads on the collar and tip so they go together easier.
I use a countersink on the collar and trim the tip on the lathe.

Collar starting to take shape.

And the tip.

Just about done.

Collar and tip separated.

As one.

Test fit on the rough horn.

The horn with some color on it to highlight heavy scratches and rasp marks.

With the sizer in it.

The blank for the base.

Rough turned between centers.

The horn cut to length and finish scraped.

The base still between centers with the taper turned to fit inside the horn. At this point I turned a spigot on the other end of the horn so it would fit in a four jaw chuck and hollowed it out.  Note to self: Should have gotten a pic.

This pic shows it turned around and mounted on the chuck ready for finial turning.

Done, no finish yet but a couple of coats of finish was put on, steel wooled  between coats and allowed to dry, the inside was also sealed.

Here is it with no color and no staple in the base yet.

 And the finished horn; about 14" around the outside curve, base about 2" held in with 4 wooden pegs. collar pimmed on with 3 wooden pegs. Color is AF with a little Brown wax.
 I hope this is of some help, if you have questions, I will try and answer them.

Beautiful horn.

Last week a fellow showed me a horn he had bought from Jim Kelly back in the '80's. I indroduced myself. Again. Wish I remembered how I colored that horn in days of yore.

Hence my Ignorant Question - what is "AF", that stain you used?
