I threw together some bamboo hiking poles this weekend. I found the bamboo at Ace Hardware. I cut some bamboo stock that slid onto the tops of the poles that accepted the grips. I used allen bolts that I gorrilla glued into the ends. I cut grooves into the bolt heads to provide some traction. I don't have the bamboo in the grips glued to the poles because they seem to fit snugly enough. They cost me about 20 bucks to put together.
