PAT ABOUT TO MILL BOLT RECESS ON SWIVEL PLATE: Pat bolting the center plate to the table of the vertical milling machine, in preparation for the milling the 5/8 inch deep bolt recesses around the four bolt holes, already drilled in the plate. It is difficult to imagine, but the round portion of the original center plates were worn flush with the rectangular portion of the plate. By installing these new plates the entire locomotive will be raised up almost 1 1/2 inch.
