I built this trailer 20yrs ago and use it yet today. All of
the materials were salvaged from jobs here at home.
Even buying new materials the cost wouldn't be that
bad for a really robust durable bike trailer. My cost
20 yrs ago was $20 today might be about $80 with new
wood.
The plans call for 27" wheels but I used 20" wheels from
an old kids bike to be more stable and extended the neck
up a bit to compensate the difference. I strongly suggest
that you find and use an old OAK shipping skid for the frame
to pickup the strength of seasoned oak instead of plywood.
Enjoy!!
