You remember my thread about the general 'wobblyness' of the Dremel
mini-drill-press ?

I contacted Dremel Customer Support - and the sent me this fairly
unbelieveable reply

http://www.ambquality.co.uk/dremel.html

The point of the drill-press is that it has built-in 'idents' that
should allow you to easily rotate the drill to various positions and
then lock it...

...but their suggestion (if I am interpreting the rather strange
'English' correctly) is to 'whack it a bit before you tighten it up'.

Precision engineering ? Don't think so.
Have ordered one of the dedicated mini-drill units - will report back!
