Thesecond objection is that the poor head .^ head, which is worked first, is welded, butit works the collar down over the coldermetal, which does not weld, and is liableto break as shown in the cut. Fig. 5 is a bolt which is cheap in con-struction, and gives good results in ser-vice, and requires no machining the taperfit, does the most of the holding, and thegrain conforms to the shape of the head,so that it will stand caulking. If there isany objection to this bolt, it would be thatthe head is a little larger than necessary. Fig. 6 is the finished bolt made from.
