I'm struggling to understand the left and right handed tape measure thing, is the problem that people struggle reading numbers that are upside down?
Think on this scenario...I am right-handed. I write, mark, nick, knife etc with the tool in my right hand. I have done for more than 70 years.
I have a 3ft square piece of 3/8" ply on my bench. I want to mark a point 15" from the right hand side near the middle. I hook my tape over the RH edge, pull out sufficient tape to mark 15" with my left hand non-writing hand and mark using my right hand. No problem. The divisions are on the far side of the 1" wide tape but it makes no difference.
Now I wish to mark 15" from the RH side
on the edge of a piece of 3/8" ply. Laid flat, the same mark must be at least the width of the tape from the edge (the divisions are on the far side) and to transfer it to the edge needs (for absolute accuracy) the use of a square. If the imperial marks where on the nearside I could transfer the mark directly to the edge face.
Now, in both the above scenarios I am measuring from the right. When I have to mark from the left, I hook on using my right hand, draw the tape rightwards, then have to lock it whilst I transfer my hold on it to my left hand, pick up a marker and then cross my hands to make the mark. Awkward. Clumsy.
In Imperial Only days, no problem. Before expanding tapes, a 3-fold steel Rabone and Chesterman tape that lived in the long pocket of my dungarees was marked right across it's width, sixteenths on on side, twelfths on the other.
The only solution I can see is to have two expanding tapes of bench use size, one Imperial, one Metric, both marked right across their respective widths. Oh, and two pockets. Oh, and different colours so I won't keep picking up the wrong one. Oh, and more patience!
If you managed to read all of this drivel without succumbing to advanced catalepsy you are very patient or you need to adopt an absorbing hobby...
