The Problem of Teardrop Cable Sets

When it comes to repairing old compound bows, one of the things that comes up is Teardrops - a tiny part that attaches the cable to the bowstring.

Modern compound bows don't have this problem as they don't even use a Teardrop connector.

However for older vintage compound bows, this is an issue for a number of reasons.

  1. Teardrop connectors have a tendency to snap the cable where it meets the edge of the Teardrop.
  2. Once broken, good luck getting the old cable out of the hole where it snapped. Trying to drill a cable just spins the cable around without actually removing it.
  3. Nobody makes new Teardrops - there are zero manufacturers. To get a "new" Teardrop you need to buy old compound bow parts.
  4. All modern compound bows use a different and more modern system for attaching the cable / bowstring.
 Thus restoring a vintage compound bow using the Teardrop system is problematic. You have to start thinking outside the box because you cannot even find the normal parts to replace it...

But there are alternatives. Cable clamps and similar items - the trick is finding one that allows you to clamp the cable, is lightweight, and allows you to attach the bowstring - which means some of the clamps you end up looking at will either be too heavy and/or make it difficult to attach a bowstring.

So in order to fix this properly I really need to be inventive.

I need to invent a new part that replaces the Teardrop, allows you to attach the cable to the bowstring, and simultaneously protects the cable from rusting again in the future.

Which has me thinking about materials.

Wood? Might snap.

Metal? Can be tricky to work with.

Antler? Possibility. I have spare antler laying around and I know where to buy more if I need more antler in the future.

And antler is pretty tough.

Industrial Plastic? A 3D printer could simply print the part I need.

The Teardrop shape by itself is ideal, but what it really needs is a sheathe that goes over part of it which protects it from moisture: A second layer which is durable, flexible, and does double duty by holding the cable in place better while simultaneously protecting is from moisture.
