yes I know exactly what u mean, perhaps even removing a small piece of external brick work (in my case) to route a cpc to a spot, I've set up my own TV transmitting station (in the past - legally) and routed 1/2" very ridged coax type cable 5 meters thru vertical voids to get "closer" to a 60' tower, I just need "experience" but cannot even get it for free ie offering my services without any pay, it must just be a "closed shop" in this business... ?
"Proper" apprenticeships are like gold dust. I was lucky and probably got one of the last old skool apprenticeships- 4 years with "the old boys" of the trade on the local leccy board, gaining a wide variety of experience and seeing individuals different methods. In time and of course too late the loss of this will be realised, that public utilities were more than just potential profit making companies
As a self employed spark I can't help you much- I've pondered employing someone and would like to help, teach, and pass on knowledge- but the red tape is probably too much for a one-man-band like me. It's bad enough the nic wanting to see my "health and safety policy statement", "customer complaint procedure", etc etc balls b***ocks s**te etc as it is. Occasionally I use a helper on a big/time critical job but I keep it cash in hand just to avoid the tape.
