I just finished this last weekend. It's just a simple wooden kayak stand composed of a frame pivoting on 7/8" dowels and supporting four nylon straps. The process can be easily replicated using a hardboard template.
I used router table to round over the edges of the "paddles" to make them look a little more authentic. With a jig saw, drill, router and template bit this can be finished in a day.
Step 1: Gather the Materials
What you'll need:
1 - 2' X 4" 1/4" hardboard for the template ~$5.00
4 - 18" long 1" nylon straps Free
2 - 36" hardwood dowels $3.50
6- 36" 1" X 4" (I used "super strips from the Home Depot which are 1-1/16" thick) $2.97 for 8'
7/8" Drill bit (or the same size as your dowels)
Drill (a drill press is best if you can't drill a straight hole to save your life)
Stapler or hammer/tacks
Jig saw (bandsaw, scroll saw)
Template router bit
1/4" Roundover bit
Router (a router table is best)
Wood Glue (use Gorilla glue or something similar for an outdoor kayak stand)
