I'm considering strapping a long surfboard to the top of my westfalia
roof and am wondering about the wisdom of this.  I want to avoid the
$200 or more cost of a Thule of Yakima racks, which I've heard works.

Here's my idea.

1) Buy six drawer handles from a hardware store.
 2) Drill holes in pop top fiberglass for  3 handles on each sides of
the roof
 3) Attach handles with 3/16" long-shank aluminum pop rivets and large
washers to distribute rivet stress
 4) put down foam pipe insulation rolls on the roof of the Westy to
protect the board
  5) strap the board to the roof using the handles

In this configuration, the board would have three straps over it.

Reckon I'll crack the pop-top roof or lose the board on the freeway or
on some bumpy road?  The Yakima rack appears to be bolted right into the
poptop and the rack supports the weight.  If I have the roof itself
supporting the waiting and use the drawer handle tie-downs to hold the
board stable, it might work...  You, think?

Is there any other cheap solution for this?

I may get a 8-10' long board.    Think long.....  Summer is coming.

Regards,
Craig
