You have ambitious plans for sure. Funny I picked myself up a round orbital sander the has hook and loop to hold the discs on.I looked at so many that when I bought it I did not realize it did not have speed control. But it works great. handly device for 25 bux. Throw some more pics up. I keep my smart ass phone in my pocket , that way I will have some pics as I go along. What bit did you use to cut the relief for your speaker ?
