sounds like a pretty simple design job... quite a contribution you can
make to a lot
of peoples lives.
whats the press for? compressing the filter media of sawdust and dirt
etc in a frame?
They will not want a custom built or high end piece for that but
something cheap
and easily available manufactured in volume... like a hydraulic jack
you can buy at a Kragen
auto supply for $20-$40. 20 tons is pretty big, cheaper by a wide
margin might be 4 small 5 ton jacks... one on each corner of the frame
if thats the application.
that way the frame can be built of lighter materials.
The way to get some free engineering would be to post some hand drawn
sketches, diagrams or photo's of the prototype to web site (that you
can get free at a lot of places).. the post the link to engineering or
design NG's as you have done here.
