I'm making an enclosure for a headphone amplifier I designed/built and as part of that I needed to drill/tap some centered 6-32 holes on the ends of some .25" square stock. Setting up each piece would have been pretty tedious so I used some items I had on hand to come up with a simple alignment setup.
This is what I came up with:

The flat piece on the right side of the vise is bolted to the side of the vise so it's a fixed reference. It actually is one of the slide plates for my 7x12 lathe I replaced with some custom-made slide plates made from MoS2-filled nylon. I frequently use it for the purpose shown.
The parallel offsets my workpiece so it's near the center point of the vise & therefore is evenly held by the vise. The 1-2-3 block shown on the left side of the vice jaws is used as a 90 degree reference so my .25" x .25" workpiece can be aligned vertically. Tolerance requirements aren't all that high so it's all good. It's just an aluminum box to keep the electrons inside
.
I started out using a machinist's square but it was a little fiddly compared to the 1-2-3 block.
