Fred,
  If you don't mind what cartridge bearings were you planning to use. 
   
  Thanks

  Yes. The quote was about $1500 for a single unit and reduced as volume 
increased to the point I could offer a pair for about the price of a 
single unit. My design featured an easily available cartridge style 
bearing that eliminates the need for preload adjustments. It used stock 
dimensioned axles and a needle bearing lower pivot shaft. I never 
pursued the design further because I didn't want to bear the expense of 
the prototype on the chance it might not be right.

I have been in touch with a local shop that made the claim they could 
translate Emachineshop's file to a useable CNC code but this has not yet 
happened. I understand it may be possible to use what I have to generate 
a 3D AutoCad file and generate some CNC code from that file. I know 
nothing about CNC programming and only enough about 3D AutoCad to get 
into trouble. Take a look at http://www.bcpl.net/~gt5s/upright.jpg for a 
look at the final design I came up with.
