Drilling peg hole freehand on my drill wasn't entirely satisfactory
so I have decided to do it proper way on my milling machine, secured to holding fixture.
Here I am using a wiggler to position the hole exactly half way between (it's 0.4mm in one half and 0.4mm in the other):
Checking with centre drill (last chance to correct):
0.8mm dia 5mm deep:
I have spent some time sorting out a quill on my milling machine (it was stiff) - my fault, caused by overtightening the four bolts holding mill head.
When correctly torqued to 50 lbs/ft it has recovered and quill is now smooth and light
End result is quite acceptable
