Dis-tance of center of vertical spindle to theface of column is 18 in., and when in thehighest position it is 24 ins. above thetable. Center line of horizontal spindleis 14 ins. above table at the lowest posi-tion. Bearings Both the vertical and horizontalspindles run on ball bearings of largediameter, allowing a maximum speed of5,000 R. P. M. if desirable on certainwork. The regular speeds of eachspindle are 1,250, 2,000, 3,000 and 4,300revs, per min. Idler pullp^s are 10 and 4 in. face, and are providedwith ball bearings, thus eliminating alllubricaton troubles of hi^h ?p?ed loosepulleys. The countershaft bearings areof genuine babbitt as the slower speedsrender ball bearings needless, and theloose driving pulley has a die cast whitebronze bushing.
