i build a lot of wires--speaker cables, interconnects, etc.
I have the stuff on the way to rebuild the crossovers on my 4 way speakers.
I am building a set of outriggers for the same speakers.
I installed a dedicated 240V 30 amp circuit for my system.
I built custom low mass speaker binding posts from all non-metal parts except the center conductor.
I'm thinking of building a custom wood chassis for my amp. But I'm less into woodwork and more into metalwork nowdays.
Ask me about my other hobbies, I build a lot of stuff for them. I have a metalworking machine shop in my garage.
