Introduction: Recurve Bow

Picture of Recurve Bow

I dont do archery at all, which make this very instructables very ironic but I have no idea what type of bow this I, as far as ive ascertained its a recurve but past that it is all a mystery to me.

But It seems to work well enough so lets get with to it.

Step 1: The Limbs

Picture of The Limbs

I cheated a little bit with the limbs i used. I bought them from merlin archery, they are 22 inches each, or at least thats what the slightly damaged sign is telling me, the limb part of the bow is not really an issue you can change it with any other length of limb so long as you get a string to match.

Step 2: The Handle

Picture of The Handle

For the handle I carved a piece of pine I found in the workshop, turns out thats a really poor idea and it crack easily, but its all they had so i had to roll with it.
I shaped it to the look of a pistol handle because I thought that would be pretty ergonomic and it kind of is but its slightly uncomfortable. I screwed up a little bit attaching the handle to the hinge minorly and managed to have the screws pop out the side a bit. But its ok because in a process of poor planning I sanded them down too.

As to why there is a hinge attached to the handle, we will get to that later.

Step 3: The Spring

Picture of The Spring

I used a die spring from an old scooter for this, you can use a better one if you so wish, but its very stiff and tough. I had to use a screw driver to pry apart the flattened edge enough to put the U bolt through. Once that was done clamped the edge around the bolt so it would fly loose... as it had done previously.

Step 4: Connections

Ok, glad to see youre still following, its probably very confusing at this point but ill try to clear that up.
The spring is connected to an L shaped piece of metal on either side, I used a U bolt for this but had to drill a hole in the metal to accommodate the second fork of the bolt. I used 2 nuts to affix it, one on either side.
The L plate is the bolted through the bow limb to the hinge, in the picture i used a random bolt I fount at home but that caused it to slip so I went out and got better ones. The hinge is cut weirdly because the edges were sticking out and I wanted to know if I could cut it on the Beverly shear and if it was a bad idea, it went fine so im going to go with not a bad idea.

The hinge is then screwed to the handle (poorly might i add) to complete the design.


Couple things could have gone better: ive just noticed that one of the limb is twisted slightly because its screwed to the handle wrong, Next is that the bow limb only has one hole in it and i wasnt willing to drill another so it only has on point of connection so the bow limb is liable to spin around when youre trying to attach the string, The hinge I got want really what i wanted but turns out they dont sell gate hinges with more that one hole in the center so im stuck with it.

An explanation may be in order at this point. Theoretically the hinge is supposed to allow the bow to bend while the spring is there to provide the force. I say theoretically because this is just me thinking how it works and i dont know if this is a real type of bow or not. Anyway it was supposed to be for a bow that didnt have bendable limbs to account for it because i cant make them myself, yet. I went with the recurve limbs anyway

Because there was no center hole in the hinge that would allow for me to have a handle capable of holding to it had to go it one of the others and so the handle is hanging out to one side, but this is mildly convient as it lets me notch arrows more center and is better.

Step 5: The Finished Bow

Not really a step
I apologise for misleading you

But it works, even though i had to order the bow string 3 times because I couldnt figure out how much I needed, getting the string on is a pain aswell, I could just be using the wrong technique I guess.

Thanks for sticking around till the end
any advice would be greatly appreciated.

As others have stated thee are alot of hazards here. But the concept and premise are very interesting. Id go as far as to say its promising. The recurve limbs are not such a good idea with the spring. Id highly suggest wrapping the handle to avoid cuts and to remove the spring. Replace it with a single bolt to avoid the limbs coming foreward and breaking/ potentially severing any fingers

As everyone else has said, your bow is dangerous, to yourself, and lacks any understanding of the physics of archery. Do not shoot it please.

The Limbs bend and store energy.... Stupid auto correct is a piece of shut..,

jscriven2 (author)2014-09-05

I understand your concept. But I think you need to research how a bow works.
The kind bend and store the energy till the string is released. Plenty of how to's here and on YouTube. Backyardbowyer is a very good bow making YouTube site for beginners.

It may be slightly dangerous... but so were a lot of innovations. Like airplanes. And vaccines. And rockets. But I still like it. ;)

It looks to me like you have a death wish... That thing could blow up and your fingers stand a high chance of being broken

bensmiller02 (author)2014-09-04

if it had the non bendable limbs like you intended this would be much better as it is though its pretty sletchy. the limbs used would function better and be safer being directly attached. im sure though I have seen bows in the style you made nice start though lets see what you make next.

As someone that has shot for many years this scares me.. Your just asking for your fingers to be pinched or worse cut off by the spring.. Not to mention the possibility of the limbs delaminating and shattering..
