Abstract
An improved shaft is described with which a sponge saturated with carbon coating can be pushed through the narrow neck of a cathode ray tube funnel to fully coat the interior of the neck with the carbon coating. The improved shaft is made of a plastic composite material, for example. This improved shaft is much less expensive than previous stainless steel shafts and has enough flexibility that it is not easily bent when plunged into a funnel that is not properly aligned and centered under the shaft.
