I built a BenchCrafted Moxon vise, using their 8" ACME threaded rods. I would like to replace the rods with 10" at least occasionally, except that I cannot find 3/4" 10" ACME threaded rods. BenchCrafted sold them at one point, but discontinued them. Nowhere do I find such a thing. Does anyone have a lead on who might? Google has been unproductive so far.
