I built the crown from 2 different
thicknesses of aluminum stock I bought at the local hobby Town.The base is bought
out of a sheet of 0.064x10x4 inch and the 12 fins are made from 2 sheets of 0.016x10x4 inch stock.I drew a 4 inch diameter circle on the base material and used my band-saw to cut the basic shape and used
the belt sander to finish the shape.It took a little planning but I drew out
the drill pattern for both holes of each fin on the bottom plate and drilled the holes using the drill press. I decided to
use small screws to hold the crown together (sorry to the purest) as I do not have what it takes to use rivets. All 24 holes
were then tapped to the screw size to be used.
To build the crown fins, I
bought a small 8” Break/Press and both cut the fins to size and then bent the 45 degree angle.I have to say, the new Break/Press worked great.I hand measured
the fins to the base, drilled and attached the fins.
Overall, a very fun little project, only cost about $10, and I think it turned out looking very nice.

As the finish I decided to
use a slight texture which helped give it a glistening look in the light.I used
my hand rotary sander with a fine sand paper and lightly sanded all the surfaces to get a consistent look. So far I am very
happy with the way my crown turned out.
