In the wheel pants kit there is one piece that needs to be separated into a left and right U-00006A brackets and a few other parts that require a light edge deburring. And then there are the four U-00002 wheel faring brackets which require some serious attention. These are very thick brackets that were sheared during the manufacturing process and have large burrs and sharp edges from the shearing process. In addition, the brackets have taken on a curve from the shearing and hole punching process … this curve needs to be taken out by the builder so the brackets lie flat on a flat surface between the offsets on either end of the brackets. I found supporting the ends of the brackets between two blocks of wood and whacking the
After the U-00002 wheel faring brackets were deburred and straightened, there are nutplate rivet holes on both ends of the brackets that require machine countersinking with a #40-100 degree countersink bit. Machine countersinking these holes can be tricky because the countersink cage hangs over the edges of the metal … suggest doing this in small increments and sneaking up on the proper depth.
Using the air drill outfitted with the countersink cage and a #40-100 bit to machine countersink rivet holes in the U-00002 wheel faring brackets that will be used to
