Hey, wouldn’t it be great if dummy axles were adjustable in length? That would remove a huge tooling cost for new builders. Product idea someone…

The threaded rods plus 6 nuts that I use (two each on the insides of the dropouts, locked against each other, and one each on the outside) are adjustable in length!

Henry James had a adjustable axle on their brake boss jig, I believe there is a threaded rod with both left and right hand thread on it. I have one, I can send you pictures.

As a supplier of all kinds of dummy axles, I’ve considered manufacturing an adjustable system similar to the old Henry James. However, with the low selling cost of round end dummy axles, it’s hard to imagine enough sales to justify the design and manufacture of a relatively expensive adjustable system in each of many mounting configurations to match existing fixtures, especially since, as noted by guy153, threaded rods will accomplish the same thing. Just my opinion as a designer and seller of bicycle frame tooling.

Round dummy axles are easy enough I was thinking more about how great it would be to have an indexed 12mm one that could do 142 and also 148 and maybe forks too… It would avoid me having to stock a gazillion different axle to run the bicycle frame classes.
