I thought about glueing a few old gift cards together and using the "card multiplex" for a slingshot..... Hmmm.... I like the design at lower right... Might have to try it!

That's a great idea! It is similar in concept to the altoids tin-compatible series that I made, except they are smaller. I presume that if you're making them credit card sized, then you plan to fit them into a wallet and will make them no thicker than 3.5mm.

Here are the challenges:
  • TTF doesn't work. Essentially it shoots like a PFS with a pure OTT action
  • The fork gap shape / tips need undercut to keep the bands on
  • Flexibility and structural strength is an issue if you are using plastic credit cards
  • Grip is a problem; you need a lanyard
  • Sharp edges and protrusions may make for an uncomfortable grip

I will update these attachments later; I will experiment with a pinkie hole derivative.

you could use thin aluminum, or Ti. but these look like fun to shoot
