Frame Assembly Continues

Today was again good enough that we could move our loco frames out into the open for another work session. First  task after setting the frames on stands was to set the cross level at or near the driving horns, the trailing horns and near the buffer beam.  This time we used a length of bright bar inserted in a hole in the frame plate to the same position hole in the opposite side plate.  Note that left and right side plates were welded together for drilling, virtually eliminating any discrepancy side to side.  We took care to mark the bar where it entered the hole and the top position to ensure consistency, although we tried turning the bar and it made next to no difference on the reading of our precision level.  Having adjusted the front right hand plate and secured it with temporary bolts, we were pleased to find negligible cross-level differences.

In the absence of a cylinder block there is a long length of unsupported frame plate at the front.  To keep the front end true have the buffer beam and its brackets, angles and a diaphragm plate.  The buffer brackets are pretty massive, and after some debate we opted to assemble them on to the buffer beam lying front face down.  This worked well, as can be seen below.  When the assembly was  lifted using the central sling seen in the photo it balanced quite well.  Fitting it to the frames was a juggling act as every fastener goes from the outside of the buffer bracket through the frame plate and a substantial backing angle.  Once bolts were tightened up the assembly was true and level still.  The diaphragm plate that goes behind the buffer beam and between the frame plates fitted perfectly.                                                                 

Next we moved to fit the boiler slides.  Unfortunately we found our contractor had flame-cut the fastener holes and it needs a bit of extra work.  However, Old Father Time said not today chaps.  It was time to finish for the day, so we tidied up and put the frame assembly back in its tent.  Today’s work has created a very big difference in the appearance of the locomotive, and we can be well satisfied with the results.

As ever, we owe a big thank you to the Keyte Smith team who have been brilliant.

Finally a reminder that building this iconic locomotive requires money, all of our funds come from voluntary donations and Trustees are unpaid.  Please support our project financially or by volunteering.
