I am making some new trapeze "wires" from Dyneema. I have spliced a thimble into one end without any problem. Now I want to splice a thimble into the other end. But to splice Dyneema, you need to pass both the short end and the long end through the cord. I can't pass the long end through, as it has a thimble in it, not to mention the trapeze handle. So how is this done?

Thanks.
