To a Shipwright a level is as useful as a chocolate teapot so why does a Cabinet maker need one? Just asking as I am a Nong with wood.

I've found Stabila ones to be the best, Stanley, Lufkin and other sorts tend to be hit and miss. It's probably not the manufacturing at fault but maybe careless shipping.

Youtuber oxtoolco has some great videos, one in particular shows the level calibration process. Very knowledgeable bloke... with lots of awesome tools and a nice shed to boot.

Skip to 7m30s if you are interested in the abbreviated version

On a construction site a few years ago I had a contractor query some pegs I had placed at building corners. To cut a long story short, he had purchased a box of half a dozen 50 metre nylon tapes at a bargain price while touring China.
When compared with my 30 metre nylon coated steel tape, his were 115 mm long at 30 metres. They all went in the skip. He was lucky that this was the 1st use he'd made of one!

That's a classic. Years ago I was working with a builder who bought us all the same tape for that reason. They had to be the same within a mm.
