This page documents the things I
couldn’t figure out from the drawings, so had to either work it out for myself
or ask someone who’d already built the engine. Hopefully, they will help you
(unless you are less stupid than me, of course…..)
1) Position of reversing stand
The
drawings are somewhat unclear as to exactly where (in a left-to-right)
direction the reversing stand goes. There are some clues in the position of the
large angle to support it and the brake column, and also with holes in the
footplate, and the cab front, but no real help. There is the suggestion that
the reversing rod has a bend in it. Now, whatever happens, the reverser needs
to keep out of the way of the brake column (this brake handle sits above the
reverser). What I did was to assemble the weighshaft, and then make the
reversing rod straight back to the stand. I made the stand sit so that the rod
runs parallel to the frames. This makes the stand very close to the edge of the
support angle, but there ought to be enough strength there
2) Crankpins
The
drawings are very unclear as to exactly how the crankpins are fitted. They
supposedly have a screw from the front face of the flycrank, yet the belled-out
end of the pin also holds the rods on. I have spoken to several other builders
about this, and they all have their own way round it. My crankpins are loctited in,
and are tapped for retaining washers on the ends. This will mean I can remove
the rods for re-bushing should this ever be needed.
