Hint for repairing broken cogs / worn cogs

For the situation where a section of teeth only on a
plastic cogwheel are worn or missing.
Wrap a piece of thin polythene sheet around a section
of the undamaged cog teeth.Wrap copper wire diametrically
around the cog pulling the wire into the root of each
tooth over an "arc" 2 teeth wider each side than the
broken section.
Coat with epoxy to form a mould and allow to cure.
Undercut the edges around the broken section,demount the
mould and reposition over the broken section.
Bind on and make good the cog with epoxy in 2 or 3
stages.Finally fettle with a file.
