Great video - triggers a couple of dumb questions. First, in the metal working world, threading dies are circular. The die you are using is a rethreading die that is intended to refresh/repair damaged threads. Is that difference significant in the application you have for it? Also, the folks who make bespoke pens understand that threading dies are very slightly tapered (the threads cut at the marked end are very slightly larger than the threads cut by the unmarked end), so they insist that threading has to be a two-step process of running the die over the spindle, and then reversing the die and repeating the process. Is that necessary with a rethreading die? Second, I often use threading taps to thread female holes in wood - for example, fixtures to mount on my headstock/tailstock, or wine stoppers. I've found that the threads are stronger if the wood is in facegrain orientation (so that the threads are parallel to the grain in the wood). But I've been notoriously unsuccessful in cutting male threads in wood using dies, but my attempts have all been finer threads in end-grain. Have you attempted to use your rethreading die to cut male threads, and if so, what has been your experience? For example, could you make your centering fixture from wood rather than HDPE?
Great video! I may not know much about wood-working, but I felt that after your presentation I had a clear idea of your process and application.
