This little beauty helps tighten wired frames. Wire the frame loosely and run this crimper over the wires. The crimping takes up the slack and tightens the wire, making it much easier to embed into the foundation. Try one, you will love it! Use with the Old Style Spur Embedder.
I found this thing pretty tough to use. I had to go over the wire several times and very lightly at first to get the wheels to spin. Otherwise it just slides along. If you squeeze too hard it wont roll. When you dont squeeze hard enough it doesnt crimp. Catch 22. Handle needs to be made of metal, not plastic. The plastic flexes. Plan for a long day/s if you have a lot of frames to do. Using the thinnest wire possible will probably help.
