As one ages it is a good idea to exercise the noggin as much as possible.

That's a nice set of tricks. I'll keep those in mind.

I bought some tools from a neighbor who was moving and this was in the lot. Great tool! https://www.homedepot.com/p/Lufkin-2...TMPN/303236201

I have the fastest method of all for anything under 36" across to locate the true center. It is called a center finding ruler. Mine is a stainless steel yard stick with a cork back to prevent marring of a polished surface. on the ruler one edge starts with zero to 36" the other edge starts with 18 to zero to 18 they can be bought in plastic from 6 inches long and in stainless up to 72" long.
There have been times when I have used the described methods in the video, a lot depends on the size and whether or not the piece has true square corners

Howcum your tape measure shows 8" being exactly 20 cm? That's not correct. 8" is slightly more than 20 cm, aproximately 20.3 cm.

I don’t see any metric tapes on here or in the link.

Compound interest on pounds shillings and pence befuddled me rather when I was nine, so I failed my 11 plus!

My wife would regularly confuse people with her decimal tape measure that she had for her iron work.
