Yesterday I wrote "no mistakes" at which point Uncle Bob e-mailed me and pointed out the glaring error. The bearings for the pony truck go through the link, but ARE NOT SOLDERED so that when you tighten the retaining screw, you have a pivot. What a bufoon I am! Thank you Bob. Bearings have now been removed, the link cleaned of solder and new bearings merely PLACED in the holes.
On a brighter note, I've tweaked the brake assembly and this now sits in place without fouling any moving bits. Whether I get any farther tonight or tomorrow morning I don't know.
If you're coming to Bournmoor tomorrow afternoon, you can see it in the flesh (no, the D49 I mean!).
See you there
