IBM 1130 typewriter (console printer) repair and adjustment - part 7

BENT HORIZONTAL LUG FOR TAB INTERLOCK SWITCH

The objective with the positioning of the horizontal lug is to allow the tab trigger lever to maintain a small space between the latch lip on the lever and the tab torque bar, so that the tab trigger lever will positively catch the latch lip when the torque bar first rotates. It must also keep the trigger latch lever pushed down enough to keep the tab interlock switch activated until the tab torque bar returns to its full rest (vertical) orientation when tab movement ends at the target column. 

I held the tab torque bar so it didn't rotate and applied bending pressure to the horizontal lug until it satisfied the conditions above. The first testing was with manual rotation of the typewriter using the hand cycle wheel, both slowly and with a quick acceleration at the start that had previously always caused the interlock switch to reset. 

This worked, even with a rapid twist of the hand cycle wheel. I then applied power to the IBM 1130 so the typewriter motor was spinning and did some tab activations using the front panel tab pushbutton. The Tab Interlock Switch was clearly active for the entire travel time of the carrier until it reached the destination tab and stopped. This works properly now.
