MAJOR MILESTONE ACHIEVED!
The fully machined cylinders are now permanently installed on the frame!
|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 upper frame rail fit and ready for reaming taper holes and fitting new custom made frame bolts.|
|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.|
