I use thick CA to hold the fletching on. You have to wax all along the edges of the clamp in case you're a little heavy with the glue. The only issue I've had is because I use bamboo and shoot shafts. The varying size of the nock end allows the arrow to move a bit. I solved the forward end by using a "V" groove but the back slides from side to side on the wire that the nock fits on. I'm still thinking about that.
