It is surely too late to count all of them, but there are 32 screws holding the driver bearings in place, 12 small crankpin screws, eight screws holding the tender truck side frames together, I could go on. The valve gear is pinned with 0-80 and 00-90 steel screws, each cylinder block is three pieces, all held together and fastened to the frames with 2-56 steel screws. Major assmblies ar held together with aircraft grade socket screws. All holes were drilled with my drills, all hand- sharpened with zero rake.
