Binn's Road Solution To Boss Slipping
|The Binns Road model room solution to the problem of bosses slipping on
axles, was to use grub and set screws with a point. These were hardened, possibly
case hardened by the grey appearance.
On dismantling old display models it was necessary to drive the spindle from the boss, as the screw point made a deep dimple and a raised burr in the soft shaft.
