The tool is made from Birds Eye maple. It is a simple design and works very well. I have made clamps from as little as 3/8" dia hose to clamping a 10" dia 8 sides flower pot. I will be selling this type clamp for around $30. If interested contact me in the comments below.
The calculate the length of a wire take the hose diameter times Pi to get the circumference, then take that times 4 and add 10 inches.
(Pi x Dia) x 4 + 10
