Very true, and the only way to think when confronted with something that's proving difficult. The key sometimes is to come up with the simplest and quickest solution that gets the job done within appropriate tolerance and time. Trying to use things already in front of you is one way to accomplish this.
Arguably this is less of an issue in the home shop, as you can take as much time as you want. But a bit of efficiency there helps you get more done and build more and more complex things.

I've used this method a few times, use a thin steel rule as the parallel supported either side of the vice to bring it to the required height. In this pic I've got it sloping to do the taper on a 1/16" wide gib headed key hence the 1/8" drill at one end.

Sparky -- My vise & parallels are 6 inches long. My widest parallel is 1.500 inches. So, I take a piece of bar that is (say) .750 X 1.250 X 6.00 long and drill and tap three (call them) .1900-32UNF (#10-32) holes such that two are .200 from one longitudinal edge spaced at 5 inches centrally symmetrical and the third .200 from the other longitudinal edge on the centerline. I fit #10-32 hex head cap screws that have had their heads turned to a slightly spherical radius (call it SR2.00 inches). I now have an adjustable "tripod" that my 1.500 X 6 inch parallel can sit on whilst I have hands free to adjust and "fit" the part I am cutting off.

Perfect, I think I got it now, thanks.
