Hi ! I have an rifle receiver made of 7075 aluminum, and the trigger pin has worn an elongated, eccentric hole in the receiver's right side. These pins are usually 0.154, with a maximum hole diameter of 0.157. My idea was to find the proper position of this feature on the blueprint, put a center drill there on the milling machine, center-drill until the eccentricity is gone, drill and/or ream slightly larger, then make a pin that is a couple thousandths smaller than that new hole on the far right, and 0.155 for the rest of the pin (the hole through the trigger is also 0.157). I had been thinking of just installing a bushing, but could find none that had a 0.154-0.156 hole, with a depth less than or equal to the wall thickness. Another idea was to turn all but about 1/8" of a 0.170 pin down to 0.155, but this also became complicated.
How does this idea sound? Any suggestions or better ideas? What should I use to make this? I know McMaster-Carr has lots of different materials, as does some of the online metal shops. Thanks!
