I don't know if I'll become a regular member here because archery is one of my many hobbies, but seeing that Ivo invited me here, I suppose I can start off by sharing my latest weekend project.
(and for those of you on EA, this is copy and pasted )
Bet you haven't seen something like this! After experimenting with my PVC recurve bows, I figured I could scale down the size, mount it on a wooden stock, and have a simple crossbow built. But wait, that's not fun! And mixing materials bothers me. I'd rather the whole thing be one material...
Thus began the building challenge: to build a crossbow without metal or wood. The only part exempt from this was the trigger, because I highly do not trust using a plastic pin to hold the massive force behind this thing.
After 19 hours, I completed my personal challenge. Not bad for a weekend project, eh?
Here I present the Synthetic Crossbow MK I, medieval style.
Overall, I would say it is a build well done! No money spent - all of it was from scraps. If I did buy the parts, it would probably be around $5. I love cheap builds!
Here's a list of the materials and parts, starting from the front:
- Stirrup - 1/2" PVC pipe flattened and bent to shape. Has a small connector made from 3/4" PVC pipe and hot glue.
- Prods - Tapered 3/4" PVC pipe with a 1" pipe coupling, which is bound to the bow with about 14 wraps of polypropylene twine.
- Bowstring - Countertwist bowstring woven from polypropylene twine with some beeswax.
- Body - Two guides made from 1/2" pipe glued onto 1" pipe for support. The trigger section was ground out afterwards and a 3" ring of pipe was shaped to brace the back of the body.
- Nut - 6 layers of plexiglass hotglued together and carved to shape.
- Trigger - 4 layers of flattened 1/2" PVC pipe glued and ground to shape. Also, three rubberbands attached to the front of the body via a small 1/2" PVC clip reset the trigger.
I've never experimented with PVC and plastics before, so I thought this was a huge success. I love the feel of the trigger being solid plastic, as opposed to bulky wooden ones and cheap cardboard ones I have made in the past (cardboard = models). Here's a close up of the trigger piece in the making:
I'll hopefully be posting a video by tomorrow. Somehow random thunderstorms came out and now it's too wet and dark to film. Be sure to check back for it's power and such!
If I happen to make another synthetic crossbow in the future, it will definitely have a stock and handle and possibly a recurve on it. That should be fun to experiment with.
Any questions? I'll be glad to answer them.
Also, I notice it looks messy with Sharpie and printing all over it. I might just leave it that way.
