Info needed on supplier/plans/ and machines

Has anyone constructed the folowing tools from the plans available at http://www.alternative-technologies.org/tools.html ?
What results? What would you change? Worth the effort 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 inch 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.

AND/OR
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.
