I have been jealous of bass clarinet players and contrabass flute players who are able to perform standing. It adds to the stage presence for certain pieces and is more visually interesting to watch.
The parts that I used to make this standing peg cost under $10 and I bought it all at Home Depot.
For the Contraforte, the peg used is 3/8 inch so it was easy to find a match. I used an aluminum rod since it aluminum is easier to cut. I have my cordless reciprocating saw, Peg stock, black Duct Tape, a Rubber stopper. After cutting the peg to length based on my height, I wrapped the tape around an end to fit the rubber stop.
