A little light to medium spannering, some sawing and a modicum of mild to serious swear words and the "arms wood" of my telegraph pole restoration project lay in its constituent parts upon my workbench.
According to the society Honorary Technical Advisor, Keith S*****, the wood for the arms is an African hardwood called Keruing.
The standard quality control test when selecting the wood was to take a random sample from a batch and smash it from head height against something hard. If it broke, the whole batch would be rejected.
Fortunately, although mine have been out in the rain for decades, they still seem to be in good order and I'm not about to submit them to such violence after all they've already been through. I did dry them near the stove for a few days though - until they began to stink the house out - creosote has a noiseome half-life similar in timescale to uranium.
Two of the insulators were, for want of a better word, knackered. Glued long ago to their bolt by a well-chewed toffee, or some industrial strength glue. They are badly cracked and will not budge from their bolt. Please see my earlier appeal for some GPO standard ceramic terminators.
Prior to further cleaning up, I couldn't resist a quick wire brush at the support irons, and also a swift blast with the electric plane across the woods. The wood now beginning to look like proper hardwood. And the metal a little more rubbing and fussing short of the first adminstration of a coat of Hammerite.
