Thanks for the offer Andrew but, at the moment, finances (lack of ) are
pointing me in the way I am going. I have worked out a stepper driver
system and now have motors turning and I have tweaked Stepster a bit and
things seem more settled. I'm now starting on the mechanicals - the mill
I am making is scratch-built as I have a contact with a scrap yard where
I can get any odd bar ends of new material I need - I just have to wait
a while sometimes until suitable sizes come in. Unfortunately, this
isn't always the bet way as I found out this afternoon - I spent quite a
while slitting a 14" length of hexagon steel bar to make slideways for
the mill table only to find, when the two parts finally parted, that
they sprung apart into the shape of two bananas - talk about internal
stresses! So, back to the drawing board - or, at least, the miller and
tomorrow I'll go back to the old way and mill an angle on the edge of a
couple of rectangular bars.

Best wishes

Ian
