Attaching a clasp with Crimp Tubes and a Crimping Tool
When you use crimp tubes, you have the option of using either needlenose pliers or a crimp tool to flatten your crimp. Typically, both methods hold equally well, but using a crimping tool makes a smaller, tidier finished look. Personally, if I use a ribbed crimp bead, I use needlenose pliers. If I use crimp tubes, I use a crimping tool. (Some people use crimping tool with ribbed crimp beads. In my opinion, the result is a mangled and sharp piece of metal that doesn’t look very good.)
Attaching the clasp is basically the same for each type of crimp bead. This tutorial covers how to use the crimping tool instead of needlenose pliers. (To see the basics of how to attach a clasp using crimp beads, see our post How To Use Crimp Beads)
How to Use the Crimping Tool
Using the Crimping Tool takes TWO steps. The instruction that are included with your tool is pictured below. You will notice two crimping areas on the tool itself, the “crimper” and the “rounder.”
Step One: Hold your crimp tube in the “crimper”. This will create a crease in the crimp tube that will be folded in step two.
Step Two: After the crimp tube is creased, set your crimp in the “rounder” area. The crimp should be positioned in such a way that when you squeeze the pliers, the crimp tube folds along that crease into a small, folded crimp.
TIP: To be extra-sure that the crimp is tight, you could squeeze the folded crimp with needlenose pliers. It’s not usually necessary, but it offers more assurance.
