Winter 2022 Update

After the initial assembly of the power bogie frames, more work is needed before they are ready to be sent away to be riveted. There are still a considerable number of holes to be drilled, mainly in the angles which connect the various parts together. This is also necessary in order to ensure that the structure is more stable when it is moved around. An important item that has now been fitted is the stretcher which forms part of the motion brackets. The positioning of these brackets is critical to ensure correct alignment when the cylinders and slidebars are eventually fitted. Although the motion brackets and associated centre stretcher are not riveted to the frames, being riveted to the angles instead, these assemblies are then fastened to the frames using fitted bolts. In order to make sufficient room to enable the angles which are attached to the left frame to be drilled, it has been necessary to move Handyman’s boiler away from the frames to make enough room for the Magdrill to be used.
