finally some more substantial components.  These are a couple of the driving wheel castings.  The one on the left is a coupled wheel (front or rear?  Time will tell!).  The one on the right is the driving axle.  For the uniniatiated you can tell because the driving wheel has a bigger balance weight!

The frames bolted down onto the mill bed for drilling.  They are both lined up so I only have to do one load of drilling, and to ensure the frames are lined up perfectly.  Picture by Stephen Trower.

working drawing for the front buffer beam.  All the dimensions have been fiddled with from LBSC's original design but fundementally its the same.

various important bits and bobs.  The bogie bolster is at the top left.  The other blocky bits are the frame stretchers.  The drag beam is at the bottom.
