+===== Commercial Iron Cross with Green Backdrop =====
+  * Parts:
+    * 1 green acrylic plate from any dime or thrift store.
+    * Aftermarket ignition cover with the iron cross emblem.
+  * Tools:
+    * Jig saw with the wider teeth cutting bit. \\ (the fine bit teeth will melt the plastic before cutting it)
+    * A file to smooth out the edges.
+    * A drill to make the mounting holes.
+    * Painter's tape to protect the acrylic.
+    * A marker to outline the material.
+|Acrylic is hard to work with. If you go too fast it melts back together. \\ If you go too slow it cracks. \\ The steel iron cross overlay will hide imperfections on the edges of the acrylic. ((photos by Johnny Wolf of the XLFORUM http://xlforum.net/forums/showthread.php?t=263640))||
