"The Scientific American Boy The Camp at Willow Clump Island"

16 iron wire,
eight large screw eyes and six eye bolts, with nuts and washers. Both the
screw eyes and eye bolts had welded eyes and the shanks of the eye bolts
were 6 inches long. A pair of screw eyes were now threaded into the
backbone at each side about 18 inches from the end, and at each end of the
crosspieces an eye bolt was fastened. I began to see Bill's plan. He was
going to draw the wire taut by tightening up the nuts on the eye bolts. To
get the best effect the hole for the eye bolt had to be drilled in on a
slant, so that the bolt would pull directly in the line of the wire. To
get just the right angle we ran a cord from the screw eye on one side to
the point where the bolt was to be inserted, and traced its direction on
the crosspiece. The hole for the eye bolt was now drilled parallel with
the mark we had traced. The same was done at the other end of the
crosspiece. A pair of screw eyes were now screwed into the backbone at the
fore end and a pair of eye bolts were set at a corresponding angle in the
ends of the crosspiece. The crosspiece was notched at each side so that
the nuts and washers on the eye bolts would have a square seating. Then we
stretched on the wire guy lines, drawing them as tight as possible, with
the eye bolts held in place by a turn or two of the nuts, after which we
screwed up the nuts as far as we could, thus drawing up the wire until it
was very taut.
