If the prints call for a solid grease cup on the strap, athreaded bushing is applied by electric welding, which givesa cjuick and satisfactory job. In fact, this is the best wayto apply a grease cup even in the case of a forged strap,there being a considerable saving over the old way of forg-ing a lump of steel on the strap, to be later machined tomake the cup. In regard to the relative cost of a forged strap and onewhich has been cut out with the acetylene torch, it is believed. Fig. 2—Straps are Machined in Pairs on a Slotter that the hitter method will result in a material saving. Inthe case of the middle connection side rod strap illustrated,the cost of material and cutting complete was $ perstrap, which would be reduced considerably if it had notbeen necessary to buy the original bar of hammered steel fromthe manufacturer on account of insufficient hammer equip-ment to forge it in the local shop. The price, $, doesnot include the cost of machining, but when it is consideredthat the Guilders charge $160 for a new strap, the totaliving will be evident. It has proved economical to cutout the straps and make them in this way, even at the highcost of hammered steel purchased, and the saving would berelatively greater in the ca.^e of a shop equipped to drawout their own steel billets.
