Laser Cut Cardboard Crossbow




Here's my fully functional Cardboard Crossbow I made using Techshop's Laser Cutter!

Step 1: Sketch

I started with a concept sketch of the parts and overall look of the design. I then did a refined line drawing from the concept sketch.

Step 2: Import

I then imported the sketch into Illustrator to use as a template to make the outlines for the Laser Cutter.

Step 3: Parts

I dry fitted the pieces to see if they line up as planned then readied them for some gluing action.

Step 4: Glue

I used some clear Elmer's glue to put everything together.

Step 5: Assemble

After the first round of gluing was dry, I used the same glue to attach the bow to the handle.

Step 6: Let Dry

After everything was dry, I dremeled holes into the edges of the bow then used wood dowels and a rubber band to finish it out.. Tada! a fully functional Cardboard Crossbow that I made at Techshop!

Step 7: Fire Away!

    i don't want to be rude but how is this a crossbow

    1 it does not have a actual trigger mech

    2 it uses a rubber band rather than tension on the string

    3 why would you use a laser cutter to cut cardboard

    bellow are some possible trigger mechs

    There's nothing wrong with this crossbow. 1: it doesnt have to be a trigger-pull mechanism, just so long as it holds the string in place, 2: yes, it uses a rubber band, but a traditional crossbow uses tension on the limbs, not the string, and 3: from my experience, it's pretty dang hard to cut cardboard neatly with scissors, and a laser cutter cuts exactly how you want it, the same way, every time. Why don't you make an Instructable enlightening us on trigger mechanisms for a crossbow?
