Hi Colin You'll probably find that the 2.5mm lead isn't exactly 10 tpi. I setup several mills with similar but slightly smaller diameter leadscrews and came up with an input scale that included a decimal something like 5088.5 when calculation says 5080.
A good deal of speed is required to keep a wood router bit sharp. You don't need those speeds for metal cutting. You might think about offsetting the motors and using 3/1 or greater belt ratio.
