Rubber Chair Feet
Step 1: Thread the trumpet
Gut a section of paracord long enough to run the length of the horn. Tie the cotton ball to the end of a strand of the inner paracord and start to feed it through the trumpet at the end where the mouth piece goes.
Use compressed air to blow the cotton ball through the horn. Once it’s through you’ll have a threaded trumpet.
In the picture you see the valves removed but leave them in when you do this.
Now tie the paracord strand onto the section of paracord you gutted. You should be working at the bell end. Take some all purpose cleaner (any soapy liquid will do) and lubricate the paracord.
Pull the gutted paracord back through the horn until it comes out the other end.
Step 2: Prep the base
Take a rubber chair foot and drill a hole in it. The pack of four cost me $1. Place the drilled foot onto the shaft of the base. Trim another foot and place it at the top of the shaft so it the trumpet has two points of contact along the shaft.
