The finished panel fresh
from the waterjet cutter. I found a local Machine shop,
Hollis Line Machine Company,
Inc.

New Hampshire 03049

to cut my panel. I showed
him a full size plot of the file and asked for a quote. The price was
right for me. Depending on the complexity your mileage may vary.

I asked John what type of
file format he needed. He said either a DWG or DXF will work. I dropped
off the file and the aluminum later that week.
When I received the panel
back I cut the Aluminum angle for the radio stacks. I even had the waterjet
cut the holes for the flush rivets. I purposely left them small because
of the tolerances of the cutter. I drilled them to the right size when
the panel was finished.

I drilled and cleco'd the
angle to the panel. Flush rivets need to be countersunk. I ran my microstop
countersink through all the rivet holes in the panel. I tried the first
rivet and guess what? the microstop moved from the last time I used it
for the spinner backplate. Lesson learned, Recheck
the countersink on a piece of scrap each time before using it.

This was no big problem. I
filled in the small depression with some super-fil and sanded smooth before
spraying the panel with zinc chromate primer.
