Used a vixen file to round the edge of HS-609PP to fit and sanded the edges with 400 grit sand paper. Rounded the edges of the bars using the scotch-brite wheel and file. Smoothed the edges and surfaces of the HS-609PPs to a satin finish equivalent to that left by 400 grit wet/dry sandpaper, removing all the milling and file marks. A combination of 2" scotch-brite disk on a hand drill and 400 grit sand paper were used. One bar had deep gouges that required removing material to 0.179in in some areas. The original stock size was 0.1875 in. Vans confirmed this reduction was within tolerances.
