Introduction: Credit Card Grappling Hook
The credit card grappling hook is a whimsical little project that combines a credit card, some simple hardware, fishing line thread, and a sewing machine bobbin. It's functional for light grappling duties, but is mostly just meant to be used as a toy and for entertainment.
Step 1: Materials
- 2 credit cards
- fishing line
- rubber band
- sewing machine bobbin
- bolt
- 2 nuts
- wing nut
- 3/16" binding post to fit bobbin
Step 2: Attach Fishing Line to Hook
Using a larks head, attach one end of the fishing line to the grappling hook. Assemble the grappling hook so it matches the one in the photos below.
Step 3: Wind Bobbin
Wind the fishing line around the sewing bobbin just like you would wind thread on the sewing machine. This is a fast, clean and easy way to load up your spool with many feet grappling line.
Step 4: Tape Two Cards Together
The structure for the grappling hook is basically just the credit card itself, so in order to keep it stiff and strong, I used double sided tape to stick two cards together.
Step 5: Drill Holes
Drill holes in the card for the hook launcher (rubber band) and the binding post that will hold the cable spool (sewing bobbin).
Step 6: Attatch Spool to Card
Attach the bobbin to the card using the binding post and then loop the rubber band through the top hole to create the elastic launcher. I made a slight dimple in the back edge of the card that the rubber band fits into which allows me to easily stow the grappling hook when it's not in use.
The last steps are to go shoot at stuff, try to real it in, and to have fun!

I like it. Imagine over-the-wall cubicle treasure hunts--snag it and you get to keep it ! But, as the safety rep, I would love to find this on someone's desk. I'd have a good presentation at the next quarterly. Remember...It's all fun and games until someone loses an eye.

Saludos Dariokastro !
Este artefacto, lo puedes utilizar como rescatador de barcos a escala, que se han quedado varados en alguna piscina, lago, estanque, ETC, por alguna falla.
En nuestro grupo de Modelismo Naval, lo llamamos "*911" (asterisco 911) o "rescatador", es muy útil, desdeluego es de un diseño diferente, ya que utilizamos un carrete mas grande, sedal o cordón, y una pelotita de esponja en un extremo.- Asi es que yo lo encuentro ideal para este propósito, ya que es de reducido tamaño y puedes llevarlo en cualquier bolsillo.
Puedes visitar el sitio en la web, de Modelismo Naval de Reciclado, es muy intresante: http://mx.groups.yahoo.com/group/ppnautica.
