Setting Eccentrics Before Wheels areUnder Chas. regard to the setting of eccentricson locomotive drivers, we have foundthat it is very inconvenient in the Clin-ton, la., shops of the Chicago & North-western Railway, or rather we havefound it to be very difficult to key ec-centrics on and properly fasten themunder an engine, especially the largeengines mostly used now, where thingsare so compact underneath as to givevery little room to work. If one has totake the eccentrics off to cut key-ways alter the valves arc set it usually means a \ ol a di re in finishing i he i ngine, tin ri foi e it is important toget tin valves set as quickly as pos-sible, and if the eccentrics arc set and ii is not level then weplumb-bob and set the board to theright incline.

We find that it is a more convenientand satisfactory method to set the ec-centrics, cut the key-ways (if on a newaxle), key them on and finish them onthe floor while the wheels are out. Wehave set all eccentrics in our shop onthe floor for the la-t fifteen years andwe seldom have one to alter when wecome to set the valves. If, as some-t
