Taps & Dies, Router Jig

[custard]

I'd like to build a couple of jigs for my routers that involve replacement router rods with a threaded section about 30mm long on both ends. My routers both take 8mm diameter rods, and I see Tilgear sell 8mm silver steel rods with bevelled ends that are just the length I need

Here's my question, is it practical to cut a thread by hand on these rods, and if so what size thread would be easiest to cut on an 8mm diameter rod, it could be metric or imperial?

M8 x 1.25 sounds like the obvious one.

To cut the thread you will need an M8 die plus a die holder. You can the lot from somewhere like Axminster for a tenner.

Upside: cheap easy & very adaptable
