I thought I'd toss this up here just for the halibut. I try not to make flaky setups, but I have a few that I wouldn't "recommend".
This is one of those. I had to make 20 of these today, so I snapped a couple pics.
This part is 1/4" x 2" flat bar, 5.2" long, profiled all the way around, and corner rounded on the top side. Finishes at 1.625" x 5.000" with an elliptical profile.
It has 2x 3/16"x1" spring pins on the backside, .200" deep in the holes. That's it. It's a cap for an extrusion, nothing fancy.
I could use 3/8" material and profile it first, then flip, hold in interpolated jaws, put in the holes and deck to .250" thick. But that would take more time and material than just starting with 1/4" flat bar, so this is what I came up with.
Pic 1 is the left vise, put in the holes for the pins.
Pic 2 is the part flipped over on the workbench with the spring pins installed. The orientation of the slot is a callout.
Pic 3 is the right vise. I made some aluminum jaws to grab it by the spring pins, profile and corner round holding on to nothing but the 2 pins.
I have tossed a part or 2 over the years doing this- squeeze the vise too hard, you squish the spring pins and the part lifts up. But I have found that if I'm careful closing the vise, they don't move.
