    Before I start talking about what I've done with this build, I want to just thank you guys for being so helpful with any questions I had regarding knots and making this project possible. My forte is woodworking, not so much knot work. <br><br>That being said, allow me to present an unfinished project <img src="http://illiweb.com/fa/i/smiles/icon_biggrin.png" alt="Very Happy" longdesc="1"><br><br><a href="http://www.servimg.com/image_preview.php?i=60&u=17228318" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/22/83/18/20121110.jpg" border="0" alt=""></a><br><br>I wanted to make a take-down slingbow that would assemble to a size closer to an actual recurve bow. I'm 6'2'' tall, with all of that length being in my legs and arms, so a longer bow was the way to go. <br><br>The bow consists of a riser, made from laminated birch plywood with a purpleheart accent strip, and limbs made from red oak. It follows the contours of a standard bow riser, having an arrow rest that lines up with the string for total accuracy. <br><br><a href="http://www.servimg.com/image_preview.php?i=61&u=17228318" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/22/83/18/20121111.jpg" border="0" alt=""></a><br><br>Here it is shown strung up for some testing with some notched dowels to see what the draw was like and if I needed any adjustment on the string. Let me tell you guys that I had to cut the tubes to about half the length I thought I needed them to be at to achieve any actual results, and they could still stand to be shorter to make for a heavier draw. <br><br><a href="http://www.servimg.com/image_preview.php?i=62&u=17228318" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/22/83/18/20121112.jpg" border="0" alt=""></a><br><br>Of course for the string itself, I used a lime green (my favorite color) exercise tube from the store that's apparently rated for 80# of resistance. The loops on the end are perfectionist loops, and every connection into the tube is done with a simple overhand knot held in with a constrictor knot.<br><br>In this stage it's simply been roughed out with various rasps, with no finish sanding or varnishing of any kind, so expect some update photos.<br><br><br>(Updates 12/11/2012)<br><br>I've sort of sanded the entire bow, giving the limbs a nice round over, and only taking anything up to 320 grit. I then stained the riser, and faded the ends to black, because the stain was ugly. As I said, I'm more concerned about this being functional, so I spent almost no time refining the shape and making everything pretty. The limbs are unfinished because I'm getting lazy. <br><br><a href="http://www.servimg.com/image_preview.php?i=63&u=17228318" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/22/83/18/20121113.jpg" border="0" alt=""></a><br><br><a href="http://www.servimg.com/image_preview.php?i=64&u=17228318" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/22/83/18/20121114.jpg" border="0" alt=""></a><br><br>(Updates 26/11/2012)<br><br>I've made an additional set of limbs to have two different shooting experiences.<br><br><a href="http://www.servimg.com/image_preview.php?i=65&u=17228318" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/22/83/18/20121115.jpg" border="0" alt=""></a><br><br>It resembles a compound bow, having a pulley on each end to act as a draw extension. This configuration shoots very fast and strong, using three strands of Theratube black. <br><br><a href="http://www.servimg.com/image_preview.php?i=66&u=17228318" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/22/83/18/20121116.jpg" border="0" alt=""></a><br><br>The string lines up perfectly, and shooting off the shelf is a lot easier than some say. I do my best to shoot instinctively, and I end up grouping within a dinner plate at 10 yards with the straight limbs. The "compound limbs" still are strange for me. <br><br><a href="http://www.servimg.com/image_preview.php?i=67&u=17228318" class="postlink" target="_blank" rel="nofollow"><img src="http://i42.servimg.com/u/f42/17/22/83/18/20121117.jpg" border="0" alt=""></a><br><br>Here are the standard limbs with the matching bandset. I made a nock using some serving string and CA glue. I'm much more accurate with the straight limbs, but then again I have trouble with compound bows anyways. <br><br>Speaking of, I've got my recurve bow en-route to my residence. I'll do a side by side comparison of the shooting results in this topic as soon as I'm able.<br>

    You will need some string stops, or the tubes will travel past the center line. Actually, the back of your hand will become the string stop, if you dont install them.<br>

    Like linuxmail i think you will get serious handslaps if you don' t put a sting stop. But i guess you already knew it. Anyway, i love the work you did on the handle, it came out beautiful. Very nice slingbow, great job mister.<br>P.S: Green is my favourite color too.

    I was thinking about putting on string stoppers, but decided against it after figuring that after transferring the energy into the arrow, the band still has to travel about ten inches to get to my hand. During the test firings, it felt like clapping but on the back of my hand. <br><br>This was sort of an experiment project anyways to answer the question once and for all if I still have any interest in archery. Needless to say, I'll be purchasing a recurve very soon.

    You guys are too kind. It's really rough work, and not really something I'm going to take to a level of finish that you'd normally see on my work. I'm just happy to have it functional. By the time I have a legitimate recurve bow, this thing will probably start to collect dust anyways.

    Again, very nice! <img src="http://illiweb.com/fa/i/smiles/icon_biggrin.png" alt="Very Happy" longdesc="1"> Keep in mind that the longer the limbs(distance between the fork tips) more energy goes out to the sides.

    I made it servicable. Like Joerg's slingbow, I can easily change out the bandset. However I can also change out the limbs, effectively giving me the ability to fully customize my shooting experience. Maybe in the future, I'll make some birch plywood limbs that sweep and swoop and have a shorter length.

    Haha, thank you. I've got some theratube black on the way, and I've got a design for some "compound limbs" which will involve a large pulley. I may also shorten the length of the existing limbs in an attempt to make a more compact fully assembled bow. <br><br>After shooting my buddy's 70# compound bow today which is about 2 feet long, I think I can handle a shorter bow.
