Introduction: How to Make a Pocket 20lb Slingbow.
Hi everybody, today I will be showing you how to make a pocket sized, 20lb slingbow using some very basic materials and tools. To give you some idea of how powerful 20lb is, at less than half draw, is can easily penetrate 4mm plywood so please be very careful when using this:)
Step 1: Things You Will Need
To make this you will need a hacksaw, some cloth, electrical tape, 1-1.5m of rubber tubing, some thin paracord and a 15-20cm length of 3/4 inch pvc.
Step 2: Cutting.
Using a hack saw or craft knife, cut just less than halfway down the pvc as shown.
Step 3: Bending.
Heating the top half of the pvc, bend the two sides down horizontaly as shown in pic 1, then cut out a notch about half a cm wide as shown in pics 2 and 3.
Step 4: More Bending and Cutting.
Heating it again, pinch in the side bits as shown in 1 and 2. After some sanding, filing and more cutting, you should have something looking pretty much like in 3 and 4.
Step 5: The Bands.
To prepare the bands, start by wrapping the piece of cloth loosely around the middle of one of the bands, then tie a 10-15 cm piece of paracord round it. Now do the same with the other band a tie the two together with a 3 cm gap in between.
Step 6: The Last Step.
To finish it off, tie the bands to the frame as shown and add a layer insulating tape for looks.
To use it, simply put the arrow in the rest, clip the back of the arrow to the string, pull back and release.
Hopefully everybody has successfully made this, if not, please leave a comment.
My next instructable will be a tutorial on how to make a taser :)

If the arrow has plastic flechings, then yes it might take them off. I used surgical rubber tubing which you should be able to get from a medical suplies shop; if you cant get that, almost any tubular bands should work fine. If you plan to hunt fish with it check out my 'fishing arrow' tutorial

what type of arrow do you use?

I used a bamboo arrow with feather fleching and a bullet-point head.
Depending what you want to hunt, you might want to up the band strength to 30lb or more if you want to use aluminum or fiberglass arrows.

I was thinking of using a fiberglass 'Carbon Express' arrow, but was afraid that it would take the fletchings off.
Where do you get the rubber tubing? is it available in Aussie?

Thanks, even though i said in my fishing arrow ible that it wouldnt work with this, it does actualy work very well if you attach a reel and line.
