Another Screw Tip
« on: October 26, 2009, 06:42:28 PM »
 This one is 15" around the outside curve including the stopper. The base is about 2" and is of Walnut with a staple for the strap. It is held in with four wooden pins.
 The tips is turned horn and about 3" long and 3/4" at the widest, it is taped 1/2 X 13. The stopper is Hickory. Body colored with AF and heat.

I like it, Tim.  Is the plug hollowed out?  I like the variation of colors showing in the tip.  Can you tell me the diameter of the tip at its widest point?

Tim,
That's another great looking horn!  With your productivity, you're gonna need a bigger bag to haul all them horns around!

Question for you.  How do you get the tip of the horn down to the right size, round and ready to cut the male threads with, I assume, a 1/2-13 die?

Another great looking screw tip Tim.  I really liked the way the color came out with AF.  Great job.

 Yes the base is hollowed out. I know it is not PC for all to be but it does help lighten the load and add maybe one more shot or so.
 The tip is about 3/4" at the widest.
  The basic shape of the tip comes from the horn on page 63 in Grant's Powder horns and Their Architecture .

Tim, are we sure hollowing out the base plug is not period correct??  I seem recall seeing some originals someplace where the base plugs were hollowed out some (golden age horns).  Probably more done to relieve stresses on future wood seasonal changes than anything else.  Maybe Art or John P can enlighten us?

 For the 1/2-13 I turn the horn on the lathe. Cut off the tip, drill the spout hole and tap it for 1/4-20. Screw a bolt in, chuck it up in a Jacobs chuck and turn it down. I use the 3/4" hole saw method for 5/8-11 but the lathe will do it too. The lathe gives you a better constant size.

 I do not think all horns with turned base plugs had the base hollowed out. I think it was a trait of certain makers or areas. I have been told that and i think I read it somewhere also.
 I would like to know more.

Tim:

I really like the tip shape on this one. Nice job. The coloring looks good too. I am still experimenting with the AF dying.

 I used the procedure outlined by John Proud in the May 2009 issue of
The Horn Book Along with some AF suppled by a Kibble/Pratt collaboration,           Thanks Guys...

Thanks for the info Tim.  I tried turning a horn on my lathe.... once!  Turned it too fast and flung it off.  I was finally able to find a 3/4 hole saw...  looking forward to trying it out.

I thought of another question.  What is your process for actually using the tap and the die?  Do you heat the horn?  Use some sort of lube?  I'm having trouble with the threads being kinda crumbly.  Maybe this horn is just stringy?

Thanks again.

 I find that if the tap and die are not really sharp the horn will tear. If the piece you are trying to thread is a little to large it will also tear rather than cut.
 When cutting threads on a horn I usually make the neck,portion to be threaded, longer than finished length and taper the front slightly to make it easier for the die to get started.  I know there are other ways but this works for me.

PS: Yes, I sometimes use a lube, just a touch of Crisco. I used to use bee's wax but it was to gummy.TC
