This may be slightly off-topic for the group, if so I apologize. I'm a home gardener whose just started some grape vines. I built a trellis with two wires going across that I plan to train the plants on the "four arm kniffen system."
My question is, how to secure the wires! I tied and crimped them onto a turnbuckle like thing but they keep slipping. I have bought some things to try from home depot called thimbles and clips and also ferrules. I can't find a tool to crimp the ferrule things. What kind of hardware should I use to secure the ends and is there some mail order farm or grape making equipment place I can buy it?
