Using 44 special taper bolts, the fully
machined cylinders are now permanently installed on the frame. This is
a major milestone in the restoration of 786!!! |

It's hard to tell from this photo because
of the angle, but this is actually a tapered bolt. Each bolt is
machined specifically for a hole, the and the hole reamed exactly to receive
it with a drive fit, per standard practice. |

New right

New left
upper frame rail fit to cylinder saddle. Taper reamer and air motor for
driving reamer are shown set up on one of the pilot holes. |

The right
side upper frame rail is new. This is a rear view of the new right
upper frame rail. Gap between original main frame and new frame is for a fit
key per original design. This steel frame key will be machined fit and
applied once all taper bolts are applied. The left side is designed the
same. |
