Xynetics platen

I don't know if anyone here knows of the xynetics plotters, they were very
wonderful machines.
I have a platten but have no head. I have entertained thougfht of building
my own linear motor head but I am fairly sure it is beyond my mechanical
abilities.
For those who do not know, imagine a huge (approx. 2m by 1.5m) block of
chocolate, made of iron with the blocks very tiny and the gaps filled with a
non-ferrous material. The head was a linear motor much like an open stepper
that cogged against those 'blocks' It had 1 thou resolution and 1/2 thou
repeatability.
So two questions,
1. Should I try and build my own head?
I have no serious workshop, just an average assortment, but would buy
specialist stuff if affordable.
2. Should I use the platten as a flat base for a movable x-y positioning
system.
or. forget it and build using something different.
My imeadiate goal is to be able to make prototype PCBs although cutting 3-d
models in the future would be nice.
Previously I have done normal etching for PCB's, I want to switch for a
couple of reasons. More reliable results, particularly if it has been a
long time since last used, automated drilling, less mess. Also would like
to be able to do some very fine work, was almost tempted to get a chip wire
bonder machine for doing fine interconnects, building something like that
might be ambitious but would come in handy.
Any ideas?
I am more an electronics and software person than mechanical systems but am
in no rush. How far in over my head am I?
