geraldthehamster has brought this to us :
I need to drill accurately some holes for taps in a 40mm thick beech
worktop.

How might I ensure that I am drilling exactly vertically, with my hand-
held drill?


Regards
Richard

A piece of steel about an 1" or more thick, with a pre-drilled accurate
hole in it. With lots of practise it is possible to drill an hole which
is near enough with any such help.
