12 x 2 mm acme (trapezoidal) tap

[C_Bubba]

Russell,
I have seen several times where people have taken a spare piece of this type of leadscrew and made it into a tap for Delrin. Certainly costs less and for a one or two off, it should last very well.

Yes, I've thought of that but I don't have a spare leadscrew and can only spare about 20 mm off the end of my X leadscrew.

Perhaps someone has a leadscrew they've removed to fit ballscrews? Anyone?
