Here is how I did it!
Cut everything out into 2x2 sections size doesn't matter just cut them out to the overall size of the shield you want. Mine will be slightly smaller than 24 inches.
I then glued a two inch by two inch square to the center of the boards with a hole in it. This is used to anchor the router and homemade jig to use as a track to arc a perfect circle!
The jig just has to mount the router base to a fixed arm with a pin/nail in the end that will drop into the glued square with hole in it on your shield piece! Nothing fancy here!
Router in action! Remember the size of the circle will be twice the length of the jig! Cut shallow cuts over and over until the circle is cut out!!
Backside of a jig! It is not as interesting as the back side of water, but that is an article for another day! I used a metal dowel I had laying around, but a nail, or wooden dowel would have worked just as well!
Here is a completed circle!
The trim rings were made the same way as the inner circles, but once the outside diameter was cut I moved the jig and shortened the stroke and repeated the process to cut the inner diameter out and it left me with a nice trim ring! Fear not the excess circle that was cut out can be used to make Ouija Boards, signs, or smaller shields for little minions!
Here they are! I used 1/2 inch plywood for the material, so they are in total one and a half inches thick! Trim ring on the front, full circle for the shield in the center and one more trim ring in the back!
I then took the router and carved planks in the shield face. I have not glued down the trim rings in place yet and I recommend not doing that until after the next few steps and possibly until after painting! I traced the trim ring onto the shield face, so I didn't carve the decorations down past the inner dimension of the trim piece.
Free handed some wood grain designs onto the shield! Just used a pencil and went crazy.
Voila! Time to stain and paint. I will update the process once that is completed! Time to enjoy some mead and dream of Valhalla!
