A simple jigsaw was used to cut between the teeth of the 500mm gear. This gear was the one which had to be made on hardboard rather than plastic because the plastic sheets were too small. Fortunately, only two gears this size were necessary and a single sheet of the hardboard was enough for both. The material is more difficult to work with and heavier than the plastic.

Cutting between the gear teeth

The oscillating tool was used to smooth the spaces between the gear teeth. The Dremel attachment was used but it failed. The hard plastic beneath the sanding strips melted under the heat, the plate that attaches to the tool broke in two places and the rivet at the hinge became wobbly. I would not recommend this tool tip.

The manual tool made from scrap wood was brought out again. This tool has worked well in the past but it is slow, tiring and uses up sandpaper quickly.
