I got some work done on re-mounting my Y-axis scale on my Sieg X3.
Instead of drilling into the cast iron, I'm mounting the scale to a
1.50" wide piece of aluminum. Milled a bit of a relief so the base will
fit on the left side of the saddle. This way most of the swarf will stay
off the scale. Now that the scale beam is vertical, it again helps keep
the beam clean.

Maybe I grabbed the wrong tap... I'll czech it tomorrow. I used a #25
for a 10x24 screw, but all the tap did was spin. All ready for tapping
bliss, had the spring loaded tap guide pushing the tap down...

If I grabbed a 10x32 tap, the hole would have been undersized (10x32
needs a #21).

Do normal taps work in 6061 aluminum, or should I go to a thread-former?
