The crossbars are made from 1" square steel tubing with feet that triangulate to the runner on the roof. Two bolts hold each foot to the base.
| Since I walk to work, I use my car for canoeing for much of its mileage.
It's not unusual for me to go on 1000-3000 mile trips with several
boats on the car. Consequently, I made my own roof rack that would
be adequate for the load. With a large canoe, it's not so much the
weight, but the wind pressure that come from strong cross-winds. It's
sometimes quite scary!

| The "runners" are made from an aluminum T extrusion that's bent to follow
the roof contour. Each piece is fastened to the roof panel with 18
threaded inserts, put into the roof panel very carefully. I
also have a thin piece of rubber padding between the extrusion and the paint.
So far, through many, many days of rain, it hasn't leaked.
