If you're thinking about getting into the trades, or maybe one of your kids is interested, understand that it's not going to be what the trades colleges sell you in the brochure.

It will be dirty, it will be hard physical labour, and no matter how careful you are you will get hurt from time to time. But it is also more mentally stimulating than many civilians might imagine. There's a reason we're well paid.

Even as the foreman, I got chased out of a janky hole by a pack of angry wasps yesterday; stung twice in the head. Every day brings new adventures...

(If you're wondering what's going on in that sloppy trash-hole, those three pipes will eventually be coupled onto by the local electric utility and will hold one high voltage cable each. Those cables will enter the unit substation in the basement, where 25 kV (delta) gets transformed into 600/347V (wye) and 208/120V (wye) for utilization in the building.

At this stage, I'm just mocking it up with couplings between our rigid steel pipe and the plastic pipe that that the utility uses, along with drainage tees. The hole will be cleaned up and filled with crushed rock below (for drainage), then sand around the pipes (for protection). Eventually this will resemble a clean, professional installation but it doesn't start out that way; we must make it so.)
