Make a Whistle From Spent Shell Casings




About: I like to Create things, destroy things, and learn about things in the process.

First  and foremost this Instructable inspired by  Mrballeng and his .223 whistle. Really like the idea, made a few by soldering but it was a fair amount of work. I then found super glue works well when whistle is used  as a desk top curio but alas was no match for a ten year old " Daddy my whistle stopped working". Then through much tinkering found a way to make them using no adhesives just good ol' friction. Before you begin clean all the casings thoroughly to remove any unburnt powder or lead residue. As with anything project dealing with firearms or any of there components use caution and be sure of all safety aspects before beginning. Do not try to remove bullets from the casing in any way other than the firearm they were designed for or a kinetic bullet puller. All casings used in my project were collected at the range on a recent trip.

1x 30-06 casing

1x 5.7x28 casing

1x .22lr casing

files / dremel w cut off wheel



Step 1: Insert the .22lr Into the 5.7x28

The first pieces that go together are the .22 and the 5.7.. the .22 casing should seat just inside the neck of the 5.7 casing. Make sure it stays even and tap all the way down with hammer. Okay that is step one down no glue or solder.

Step 2: Marking and Cutting

When marking the casing measure 5/8'' from the base and make a line. Next turn the casing to the head of the .22lrmark between 1/4-1/3 of the head. Hole has to be just right to get good sound so go smaller first because you can always take more off if needed can't put back.. After you are all marked tighten 5.7 in vise and slowly and carefully start filing or turn on your dremel and quickly and carefully cut the areas of as marked. Now that the pieces are cut smooth out any rough areas. We are finished with the guts of the whistle still no solder or adhesives.

Step 3: Measuring and Cutting the Body

Next step is to line up the parts to mark for the cuts to the body of the whistle. lay the insides of the whistle next to the 30-06 casing and mark where the end lines up. Then move the 30-06 casing to the vise and again file with3/8''-1/4'' triangle file or cut with dremel 3/8 down then over 3/8 and down at a 45 to the same point as first cut. after cut clean up any rough edges.

Step 4:

Now that the body and insides are complete it is time for final assembly. Line up the casings so that the whole in the body of the 30-06 is lined up with the small opening in the .22lr casing. Make a line so you keep them lined up during assembly. Again use a hammer to gently tap the insides into the body. As you get close(Be sure isn't full of brass shavings first)blow through the whistle after each strike to get the best sound quality because if you drive it to far in the holes will not line up as they should. All that is left is to smooth out rough edges and remove any overlap at  the mouth piece.

Step 5: Finishing Up

After you have gotten it all smoothed down to your liking,  wash thoroughly and enjoy for many years to come no rust ,no parts coming off and best of all very  easy. Again Thanks Mrballeng  for the Instructable that inspired this one.

How would you recommend cleaning the casings?

no, not with in conjunction with the other shells. If you have a shooting range nearby you should be able to ask for a spent casing. if not i can send you one next time i hit the range. that is if you are 18 and it is legal in your location.

.30-06 Springfield U.S. Rifle cartridge, 5.7×28mm Belgian Pistol cartridge, .22lr(long rifle)
used in many pistols and rifles.

I end up throwing away things and then later wishing I had them handy. :P I'm kind of a clean freak though. Whenever I'm not doing a project, my workbench is spotless. :-)

My problem is my work bench is never clean. i always have multiple project going on at once. Every once in a while they turn into something worth posting.

I have too much stuff worth posting. I finish one project, start to make an instructable and then start a new project. Maybe I should follow your example.

thank you for checking out my 'ible but that was covered in the opening paragraph. " Before you begin clean all the casings thoroughly to remove any unburnt powder or lead residue. As with anything project dealing with firearms or any of there components use caution and be sure of all safety aspects before beginning." thank you

you might want to wash it inside and out. those cartridges are contaminated with lead.
