I have redesigned my low cost dyno to reduce the cost :-)

Rear axles are getting expensive in junkyards so this design 
uses a couple of $10 one inch pillow blocks instead.
The brace tubes to the firewall can be made from conduit
flattened on the ends with a hammer and a hole drilled in
the flat parts to bolt to the firewall.
The shaft can be a one inch bar or thick wall tube. The frame
was changed from lumber to one inch angle iron and welded, 
Nothing fancy here.

The pillow block can be bought from Surplus Center
1-800-488-3407. Ask for the 1999 catalog.

BTW they also have a new 30 amp 16 pound alternator for $49.95 and
some oil water heat exchangers suitable for our purposes.
