I made 3 standoffs for a small audio amplifier that my dad needed to boost the audio on his TV. He had binned the Cable TV in favor of going back to an antennae, and WOW, that antennae works great. High definition video for free rocks!
Anyhow, just took a piece of 3/4" round 6061, turned to 5/8" (15.875mm) and drilled a .177" (4.5mm) hole through, cutoff to .551" (15mm) long, deburred....done. Then drilled three holes in the outer shell, screwed it to the bottom side of his little table next to his chair and reassembled. My son ran a fiberoptic cable from the TV to a FO/analog converter, from there to the amp, to a pair of small speakers. Sounds GREAT though it only works when the DVD player is feeding the TV. Strange, and we couldn't why. More work electronics coming up. :(
