DIYbanter - Info on tools, plans and supplier needed

Has anyone constructed the following tools from the plans available at
http://www.alternative-technologies.org/tools.html ?

What results? What would you change? Worth while to build? etc.

Any problems with the supplier?

Thanks for the info.

[hand] Metal Shaper

A metal shaper is indispensable for certain machining operations where
flat surfaces must be produced within very close limits, such as
machining flats on castings, cutting keyways, rabbets and grooves and
reducing the thickness of stock to a given dimension. The Metal Shaper
has a 3" stroke, is manually operated and has been especially designed
to reduce machine operations in construction to a minimum. Cold rolled
steel flats and squares are used for nearly all operating parts and
the frame and base. These parts you can purchase cut to size. Plans
only.

Electrical Discharge Milling
Electric sparks are the cutting edges of the new tools to machine hard
metals. In electrical discharge milling , or spark machining as it is
sometimes called, metal is removed by controlled electrical discharges
across a dielectric gap. This process process is used for regular shop
jobs such as drilling, reaming, broaching, die sinking and grinding
and other work in hard metal alloys which are impractical to carry out
with conventional equipment. Even common every-day materials because
of contours to intricate for shaping by standard methods are routinely
handled by this little wonder. But now you can put Electrical
Discharge Milling in your own home shop with these plans and
instructions.
