I'm in the development stage of making a dogstake to fly my kites through. Dogstake I hear you say. It's where you fly your kite with the strings looping around a pulley so you are facing the back of your kite. Like line bending but with a specific piece of kit. It's not a new concept, was first introduced by Lee Sedgewrick in the late '80s. I have been doing line bending using the soccer goals at the park across the road from my place. But looped around a pole is far from ideal. Hence the idea to make a dogstake. Or rather, to make up a set of pulleys to attach to a dogstake and use that.
I got some pulleys that are pretty good but short of making the trek to a sail hardware wholesaler the D shackles have been a bit of a pain. I need the extra wide mouth to accommodate having 2 pulleys per shackle. Think I'll have to bunk out of work early and trek to Whitworths or bite the bullet and pay for delivery.
