Today's update: 5/32" drillbit and pair of channel-locks got the link pin in. Extraction reliable, ejection fails every time as nose of snapcap gets caught between barrel hood and ejection port edge. Thinking I need to cut down ejector by about 1/8", the amount of barrel hood projecting into the port at start of ejection stage.
That'll be another time; I'm gonna take the win the guys at Lowe's helped me get and call it a day before my gal drops an email with another make-my-brain-bleed cosplay idea. (She's been talking about wanting to get medieval with plate-mail... I don't think she understands that a loaded modern plate carrier like my Corps-surplus MARCIRAS weighs as much as a small child and Old School even more so... so I've suggested start with faux-leather costume armor, hit it with Plastidip or something similar to stiffen it then good ol' Krylon Chrome. Don't look at me, fellas, I didn't build the Big Top in the Circus of Crazy around me, I just try to keep the clowns from turning themselves into elephant toejam or getting cross-threaded with the knife thrower...)
