It's readily available at the corner hardware store, and surprisingly a lot more flexible and easy to work with than I thought it would be.
I do have one other question with regard to this project. My plan has been to use soldering lugs so as to avoid any chance of "boiling" my pots, and in general to make the whole thing a bit easier to complete. However, my body is rear routed, with no pickguard, and I am not sure with 10mm (short) pot shafts I will have the length I need to use the soldering lugs. Any thoughts on this?
