Decided it was time to do the artwork and control panel acrylic.
First, I practiced with some scrap and a control panel that's needed this done for YEARS. Clamped down, flush trim around the edges, small pilot holes, then a large pilot hole, and then the flush trim around the inside of the button holes.
Well, shoot, that came out virtually perfect. Time to go after that $30 piece for the pedestal.
One joystick hole got a little wobbly, but it'll be hidden with a dust washer anyway (and answers the "dust washers?" question). Swept the ground really well and laid down the poster.
And here's what it looks like after my high tech cutting system consisting of standing on the plexiglass and running a razor blade around the edges.
