With these free plans, anyone can print, trace, and cut out their very own crossbow. The steps are simple. Buy a slab of 1/4" plywood, cut 7 rectangles out of it that fit the dimensions of the crossbow, stack them, trace the design, and cut it out. 3 layers will go in the middle while the remaining 4 will split and sandwich the middle 3 equally.
The rest is cutting out the revolving nut and trigger, finding some 1/2" CPVC pipe, and cutting out the unique middle layer parts.
EDIT: IMPORTANT: Plans somehow got larger in PDF form. If you print this, you will need to shrink the size a bit or else the bow you make will by a giant one. For reference, the actual size of the butt end of the stock is 4".

the revolving nut.
Progress has been going slowly on the new crossbow. For this one, I am using Solid Edge Drafting, a 2D CAD program available for free online. You can try it here if you are interested. The program has helped me draw out the crossbow design and turn it into a printable PDF.
The crossbow itself is going to have a 5-layer body. The first two outer layers form the shape of the body and the bow-prod holder on the front. Between this two layers are the last three, which make up the trigger system. The reason for 5 layers is that I wanted to keep the same style of trigger while also giving space inside the trigger, the revolving nut, for the arrow to hook the crossbow string. To do this, the revolving nut has to have a wide enough opening in the center for the arrow and needs strength on the sides with added layers. Each layer of wood will be either 1/4" or 1/2", but I'm not sure which to use where just yet.
Right now, the next step is to cut out the layers on cardboard and glue them together to see how comfortable it is. If there is anything awkward, it will be easy to fix it in the drafting program.

Yep. The first crossbow I made was made out of a yard stake using a handsaw to cut it. It is gone now. Here are some pictures of it so you can see how bad it was. When I edited the pictures (in 2009), I thought it would be important to add a little watermark. Thinking back, that was really unnecessary.
After making the yard stake crossbow, I made this one.

I put the original crossbow scans into a PDF with all the pieces prearranged. You just have to print it out and tape the pages together in the page order. Enjoy!

It has been a long time since I've posted a new video. 8 months since. I haven't posted any videos in 8 months because I have lost interest in building things. College is coming up, high school is at its most important point, and other issues are keeping me from making anything new as well. My "track record" for posting videos on a regular basis is bad, unstable, you know. Those issues are not going to stop me from trying something new.
The compound crossbow, which was the last video I posted, has been upgraded quite a lot. I inserted fiberglass rods, removed the pulleys, sanded down the body, added a guide, and stained it a dark red color. The string is still that bright green though. If I do post a new video, the crossbow update is going to be the first one, and following that, hopefully, will be an assembly guide if you would like to build one. A guide video has been requested over and over and over.
I want to get the community involved with a sort-of interactive question box near the end of each new video. Once one weeks video is posted, at the end of it will be a box that says "last weeks video" and another box that says "next video." The choosing of the "next video" will be the interactive question thing. I will pull out some object in the video and ask you to comment on what that object can be made into or be a part of, and I will make the best comment's idea.
