I'm hoping to make a shallow waveguide for a tweeter I have, and would like to barter for the use of a CNC machine. I'm basically just making a depression in some MDF - fairly limited precision is required, and it's only going to be about 4" x 4" z 1" deep, tops. I haven't got much money, but I do have a big pile of audio bits, speaker drivers, power transformers, and other goodies I can offer in trade.
I have a 4'x4' homebuilt and would be willing to help. I am located west of Hwy12 just outside of middleton. Email me at madtownrob at gmail dot com
