A friend stopped by the other day. His wife had purchased this neat horn for him….. Unfortunately it was missing the crook that allowed it to play in a key….Many old horns have lost their crooks and have languished, often for decades, without being played…

To build a crook we needed to find a correct taper for the leadpipes entry into the horns leadpipe receiver…..

What you need is a collection of cartridges, each has its own taper, and by trial and error we found the correct taper….a 22o Swift cartridge.

The crooks -5

 

Just happened to have a box of empty cartridges….

 

 

The crooks -6

 

Needs a little work, but it will work….The crooks -7

In the East the owner had a crook made, it played in the key  of F#,  sort of… The solution was to build a crook of the correct length to place the horn in a useable key.

 

The crooks -8

We had the materials, 5/16th and 3/8″ empty brass tubing, and….The crooks -14t

A .220 swift cartridge , which needed to be cut apart to make a tapered crook receiver, both ends had to be cut off, both the bullet end and the primer end.The crooks -15Pix of  The cartridge with the bullet taper still in place…A decision was made, fill the 5/16″ tubing with #8 lead “bird” Shot. so the end of the empty tube needed to be filled with lead shot and then with a The crooks -10plug in place, and …The crooks -11Covered with another empty case to prevent the lead from “leaking” out the bottom of the tube…The crooks -13The stop case is a .405 Winchester (Teddy Roosevelt’s favorite used in a 1895 Winchester lever gun) The crooks -16The tube is filled with shot and heated. the shot melts at about 600 degrees, far below the brass tubing….The crooks -17The tube and stop shell is held in a vise….The crooks -18Heated with a torch….refill the tubing, because the lead shot only occupied about 50% of the tubing and re-heated to melt added lead….The crooks -21Amount that the melted lead shrank…. (is that a word???)The crooks -23Repeat until the tube is filled….The crooks -19Weight of the tube prior to filling…The crooks -20With lead inside….

More to follow….

  1. Cornell chem dept has an optical microscope facility that was founded by Emile Chamot. walter mccrone was a grad student there. Mccrone gained some notoriety in the 40s (WWII) for helping figure out why our munitions factories were exploding. unstable crystallization states in the explosives manufacture process. very visible in microscope slides of the material. we had a Journal publication analyzing the shells that were produced for the war effort. photo of the intrepid microscopist sawing through a live cartridge to gather the material. caption stated “safety spectacles should be worn during this process.” loved that. anyway, you have the advantage of better industrial knowledge of how to avoid unstable (premature detonation) crystal states in your ammunition. still, sawing through a live round would give me the heebie jeebies. stable or not. That is some real dedication to your find-a-way craft.
