In my early working life I was employed by a local council building maintenance department. I was never sure if some of the phrases were to do with the trades or, as the council bordered on the town of Bolton, if they were Bolton dialect rather than my local Manchester one.

Anyhow, one that sticks in mind was used by the joiners when something didn't fit quite right and it needed an extra bit of pressure - 'Give it a good thrutch'. Meaning force it, quite often with a mallet. Just looked it up now and one of the meanings is push, press, or squeeze into a space when climbing. "I thrutched up the final crack to a small pinnacle" so it sort of fits in.

Amazing what you find out on these threads :-)
