I downloaded the Bussman Fuse Block blueprint from online in order to ponder and design the panel in the airplane. The problem is the print is metric and all the dimensions in MM. So using the calculator I transposed the measurements to decimal inches and made a sketch of the cut outs and attachment holes. I laid out the location of the cutout on the Fuse/CB panel where it would fit best to have a reference for cutting.
I also marked wher the cutout for the cupholder would go on the mid panel cover as well as the centerpoint for making the cutout.
It appears all is in order for making the cuts next session.
