This was funny and detailed buiding instruction video. I am very experienced mechanic and have all
the needed at my shop, so I can't tell how accurate that $20 is and perhaps much more here in
Europe, but one is sure, this was so detailed that everybody can build this. As I told, I'm very
expereinced but still could find a new way to build the wheel. That was one of the best advices in
this video. So, why only 4 stars? That's because I believe that the cost of the materials is much
more that twenty bucks. Anyway, the structure is good and I believe that this can last longer than
cheap factory produsct. One add to the instructions: You should secure the nuts using spring washer,
locking compound like nail polish or what better, locknuts (Nyloc).
