My Victoria U2 mill has two arbors, a 1" and a 1 1/4". I figured it would be helpful to have a way to remove the end nut from either one to prep it for a job while the other one was mounted in the mill. I cut a piece of rough aluminum that I'd picked up a few years ago at the scrappers.

Cleaned it up on the shaper.

Drilled and bored the blank on the lathe, then cut an internal taper close to the NMTB 40 taper on the arbors.

I drilled two holes 1/32" undersize for a pair of 3/8" steel pins and reamed them to 10 thou under. Unfortunately, the drill bit had already made the holes oversize.

The holes would have worked with a drop or two of locktite, but I wanted to try knurling to increase the size of the pins.

Next, onto the mill to cut a couple of rabbets to make the wrench easier to use in the vise.

Then to the press to instal the pins.

The finished wrench in use to strip and set up an arbor.
