Assigned machine duties as usual. Throttle shaft clashed with the coolant outlet tube on an LS with a FiTech port injector set up on a 1970 Jimmy(Blazer) mounted on a 2002 Tahoe 4wd chassis. The shaft needed shortened and a new set screw flat milled. Couldn't tap the shaft out of the accelerator cable pulley so bored a 25/64 hole in a 3/4" round stock to fit down over the 3/8 diameter throttle shaft; couldn't press on the end of the shaft as it is weak from the long slot in the center where the throttle plate goes. Used a 9/16 socket as a receiver for the pressed out shaft. Found out the reason the shaft wouldn't tap out is FiTech uses a SECOND set screw on top of the one that locks the cable pulley to the shaft. Needless to say the 55 ton press jut pushed the set screw out the side of the aluminum throttle cable pulley. Milled out the entire damage in the original set screw area, built up with the tig welder, milled surface flat and even with the adjoining surface, then drilled and tapped a new set screw hole. Now a mere two hours later I shortened the throttle shaft and milled a new set screw flat on it. Could only charge the customer for a half hour.
