North Peg and Polar Alignment

[M40]

Hello all, I couldn't understand why all of a sudden, polar alignment became an issue and it felt like the azimuth screws had stripped. Found the challenge quite quickly in that the north peg had become loose somehow. Tightened it and all is good. Just a nudge then that its worth checking the obvious first.
