Nial and Brad,

thanks for the compliments- that was me and I still
have plenty tubes left :o)

I don't mind if you hand over your set though, no
worries...

While a lathe is fine and helpful, it is not a
necessity. Trickiest bit being the tubes.
For the locking mechanism's cam-disc, however, a laser
cutter could be helpful. But rather as a perfection-
my jigsaw work does the job perfectly well.

Nial, you may wish to refer to my post of
Mon, Mar 22, 2010 at 1:55 PM for details

or contact me directly at
wolfgang dot hasper at web dot de

For the handle/base tube I have made myself a mandrel
to secure it on the mill and machine the 20 grooves.
works well :o)



Regards
Wolfgang
