I got a screwdriver and a good shop to recommend. This is a small local hardware store, one guy there. I ask for a narrow flat blade screwdriver and he shows me what they have on the rack. I find a 3/16” that looks it would work, but it has the usual trapezoidal head. I measure it and it’s almost exactly 1/4”, so I’m not sure it’ll fit.“You could just grind that off,” he offers.“Yeah, but I don’t have a grinder.”“Oh, you can use ours.”“Really!?”“Yeah, sure.”“Then I’ll take it!”He rings me up, then leads me back to the grinder and lets me loose. Screwdriver worked great. So if you need some tool help on the north side of Chicago, go to Andersonville Hardware. I’ll definitely be back.
