Inexpensive heavy dusty adjustable feet for table jig or bench

[PJs]

Had a brain fade the other day, hot about 113 F in the shade so didn't do any welding on the stand. But had a thought, it would be easy to fabricate a 4" bed extension to bolt on to the rear of the bed and that would get the tailstock out of the way and give me a bit over 14" between centres, what do you think?

I was up in Oodnadatta in mid March on my trip and it was ~140°F and the black flies looked like moving ground cover, when they weren't trying to climb in my nose...hard to do anything above 115°F for me too. Anything is possible, but for my "precisionist" sensibilities mimicking the ways, height, level, lateral alignment and attachment seems pretty daunting without tools I don't have or access to.
