The freshly varnished doors,when placed in between these projectingtapered pins, .can only have point contact. Jig for Drilling Retaining Rings on Drill Press. Tests on driving spikes in bored boles oftreated ties, show that the point should betapered on four sides to drive holding power is slightly decreased byboring before treating, and while the tie ismore thoroughly permeated, the conditionof the fibre to withstand splitting andcrushing is not as good. The same attachment is used for drillingthe retaining rings. On the same pin cen-tre, there is mounted a wooden ring frame,which centralizes the retaining ring, whenthe boles can be drilled to mate the wheelcentre by the use of the drilling jig. Using the vertical drill in this manner,it is claimed that equally rapid workcan be performed as with a radial drill onthe same kind of work. With a radial, with the pins at the top edge of the door,from the fact that each side of a pin pre-sents a sloping surface, contact along whichis impossible unless the bottom of the doorbe set over at a large angle.
