Firstly, more serendipity. The problem of the missing 3 ceramic terminators has been solved. I have been walking the same route along the lanes at home for a near geological timescale. Yet last Friday evening at dusk, and completely unseen in all the previous 16,409 times that I have passed it, I spotted an ancient "arms wood" with 3 GPO insulators in immaculate condition. At some time in the distant past this had been removed from the pole nearby and the farmer had used it to block a hole under his sheep fence. Whistling nonchalantly, I clambered up the bank and quickly relieved it of the ceramics. Some people would be astonished that something as mundane as this could make my day.
The very next evening I went back and recovered the wood too - making good the hole in the fence with an old plank of my own. Another piece of telegraph pole history to restore.
Ever diligent, Society Honorary Technical Advisor Keith S**** H.T.A. T.P.A.S. quickly wrote to me with some advice when he read my last post on the subject of my pole restoration :
Cannot recomend rapid drying of arms wood which could lead to deep cracking of timber known as 'shaking' in the trade .Store outside under cover until comparative weights of samples indicate desired moisture content.
Wet weight minus dry weight times 100 gives percentage moisture content:
[ mc = (w1 - w2) x 100 ]
Or you could just leave them till they look ok.
Alas, this counsel came a little too late - after just an hour in my warm office the black wood tar seen at left, oozed from the wood I had just rescued and stuck to anything that touched it. The smell has only just cleared days later. Anyway, that formula all sounds a bit much like school algebra, so the "leave them till they look ok" bit will more suit my modus operandii.
