Mounting Terminals
HE easiest way to mount a terminal on. an ebonite strip or panel is to drill a hole slightly larger than. the terminal shank, pass it through the hole, and tighten up the nut with a pair of pliers. Unfortunately, however, terminals mounted in this way often work loose. Most set manufacturers tap terminal holes so that the nut on the back merely acts as a lock-nut, but very few home constructors: possess a set of taps. An alternative scheme is to drill the hole slightly smaller than the terminal shank and then gently but firmly screw the terminal: into the hole, _The metal screw, being considerably harder than the ebonite, makes.its own thread in the latter, it being quite impossible to withdraw the terminal without unscrewing it.. Do not drill a hole of such a size that it is difficult to force the terminal shank into place, or otherwise the very tight grip that you will have to take of the terminal with pliers is likely to mark it and spoil its appearance.
