Hi everyone,
I've just watched a chassis I've rebuilt sail down my sidings
completely free from tight-spots. I wish I'd had the jig when I built
the loco originally.

For the record, the loco is a 7mm SDJR Bagnall 0-6-0T [OK - what
modellers call a "Jinty"] from a JM kit. I'd worn the nickle-silver
laminated coupling rods bearings`oval, so have replaced with milled
steel ones. Naturally, that meant resetting the axles to suit the rods.
The JM hornblocks had also worn, so I replaced with Fourtrack cast ones
on the first 2 axles, which have equalising beams acting on the
bearings.

I'd recommend the jig to anyone. Money well spent.
Terry
