#2553: BlowBristles

It can be a pain to disassemble complex components to be able to give them a wire brushing on hidden or recessed surfaces.

Today’s invention attempts to allow this to happen effectively with everything left in situ and without having to spray sand or beads everywhere.

A flexible pipe is attached to a high pressure airline.

Air is blown down this, which causes a thistle-like ball of wire (blue) to oscillate in the airflow, restrained by a flexible cable (red).

This device can be pushed into place behind components (grey) so that the oscillations of the ball rub any flakes of dirt or rust etc off the surface.
