Coachsmiths barrel heads of scroll-irons, or pipe-eye scroll-irons, are usually made as follows. For an ordinary sized one having an oval stem, take a piece of square edge iron l in. by 3/4 in. and well upset one end, making it rather wider it is thick, setting it in slightly about l 1/2 in. from end to help in forming the eye, and round it off a little. Then make hot a piece of flat iron l1/4 in. by 1 1/4 in. or 3/8 in. thick, according to the width of pipe-eye required, and with the top and bottom fullers set it in to make a round boss; nearly cut it through at the narrow part with the gouge, and weld it on one side of the iron already upset. Make another boss, and repeat The weld for the other side, at the same time working the pipe-eye to shape and size, and working up the oval close to the eye with the fuller so as not to cut in, afterwards using top and bottom oval tools. When the eye is something like the desired shape, punch a small 3/8-in. hole through the centre, gradually making the hole the required size with a steel mandril and working up the round eye in top and bottom tools.
