How to Measure with Steel Tapes ?
A steel tape measuring set includes the following name given below:
- A 100 feet steel tape, with but a few marks on it.
- Two handles for the one hundred feet steel tape, - split sticks, long, will do.
- A 50 feet steel tape, divided to hundredths of a foot, in its case.
- Two brass 1 lb. plumb bobs, with strings.
- Eleven 6" wire spikes.
- An axe.
Line staves may be needed for ranging lines.
The edge symbol for distance are on both tapes. This must be done before accurate calculation can be made. The ends of the 100 ft. tape often do not indicate its length, there being an extra 1.'25 to 1'50 steel ribbon at each end. The 0 of the 50 ft. tape may be set up by turning off the edge of the tape back; matching the 1 ft. symbol to some other foot symbol on the tape ; smoothing out the loose edge beside the tape; and noticing on it, exactly where the next foot symbol fits, at, or near, the free edge. Keep the steel tapes wound up, - as much of the time as possible, and get the work done.
The 0 edge of a tape goes forward, when calculating. The handle at the front, or 0 edge, should not fall off from the tape of itself. The handle at the infrequent, or 100 ft., edge, should fall off very easily, because it should be taken off when the tape is drawn forward.
