In another thread there was conversation about tape accuracy. Just for fun I ran my own unscientific test. It surprised me a bit. As a control I used the steel rules shown plus the scale. They all matched up very well over a foot. What I found with the tapes was this. They all varied between a 64th and a 32nd inch to inch but they were all very close at the 12 inch mark. The older 25 footers (two rivets at the clip) were better than the newer 3 rivet one. Of the 16 footers the duel measurement one was the best. The best of all was the 3ft pocket one. One if the Lufkin mm tapes was very good at 30mm. The other two were about 1/2mm off. All in fun of course. I did not use the clips when taking measurements.
