To put the driving wheels under theerected boiler and frame was half a dayswork for several men, the appliances beinga cord (more or less) of blocks of woodand four screw jacks. It was possible toget along with two jacks, as only one endwas raised at a time. Every piece of the engine was requiredto be made in the best manner possible;all parts fitted together were required todrive, and all screws and nuts towrench. With the accurate tools of the present,it is easy to accomplish this, and also to. OLD COLONY LOCOMOTIVE they were bored, the keyways were splincdwith a tool fixed in a bar attached to tliefootstock spindle, forced forward by ascrew. There were then no hydrostatic wheelpresses, and the wheels were forced onthe axles by long bolts and nuts passingthrough heavy straps outside the the force thus applied was not quitesufficient, a few blows from a 50-poundsledge were found to help. Keys of bestcast steel were fitted to drive with all theforce they would sustain to make loosen-ing of the wheel impossible. The crankpins were forced into the wheels in asimilar manner, and were riveted in. The frames of engines built by Hinkley& Drury were made of three bars of of these were about 4 inches wideand Yi inch thick; the other was perhaps2 inches square. The three w^e rivetedtogether to form a kind of channel-bar,which was placed open part below. T
