I begin by drilling the holes for the USB ports. It's not esay to make to nice small rectangular holes. Some more filing to do on this one.



Then I isntalle the small bracket on the subpanel that will get the clamps for the throttle and mixture cables. The bracket is supposed to go where I have installed the radio trays. So after some tweaking, theis is the end result. The bracket is bolted to the transponder tray using two countersunk screws.



This is the top of the tray, I drilled two holes to be able to use a screwdriver to install then two screws. This has to be done before installing the radio tray.



To end the session I disassembled the park brake valve bracket as I 'm not satisfied with how it looks. I'll make a new one tomorrow.
