I just finished my latest slingbow, made entirely from an old bed frame and random household crap with an all-black finish for that "commando" look.<br><br>The whole weapon took 6 hours to make, from conception to finish, using a sharpie marker, a manual saw, a drill, a pocket knife, a hair dryer, some Sellotape, eight office bands, six small elastic bands, one meter of string, some sandpaper, a paintbrush and some black paint.<br><br>Whilst it's definitely not the best slingbow, It's accurate enough to consistently hit an A4 sized target at 8 meters (with unfletched projectiles), it's small (and light) enough to not get in the way when it's not being used, and it develops enough force to send a crappy home made arrow through two full water-bottles (making a right mess in the process!) and into the wooden board serving as my backstop!<br><br><br>Photos:<br><br><img src="http://i1056.photobucket.com/albums/t362/ultimatelizardman/image_zps418ba607.jpg" border="0" alt=""><br><br><img src="http://i1056.photobucket.com/albums/t362/ultimatelizardman/image_zps789a9166.jpg" border="0" alt="">

I upgraded to twelve office bands and increased the tension; not only does it now develop much more energy, but the arrows also fly through the air more accurately and appear be capable of retaining their momentum over longer distances.

Update!

Just replaced the office bands with "Barnett high-quality slingshot tubes"; my "com-bow" can now propel homemade arrows (made from sharpened 140mm nails sellotaped to wooden shafts) with enough force, at a distance of 8 meters, to penetrate a 5 mm steel plate and get stuck in the wooden backstop!
However, it's crude design is extremely unsafe when used with powerful rubber and has been responsible for 4 serious arm-slaps (one of them leaving a bruise the size of my fist on my upper arm in addition to stripping a small amount of skin off of my lower arm).

My conclusion is that this type of slingbow would make an excellent survival tool once it undergoes several design modifications in order to improve safety and manageability (curved form, ergonomic grip, band-stoppers, reduced length & arrow guide).

maybe you shold attach the bands laterally to the frame, on the right if you are going to hold with the left hend, and add some band stoppers, to protect the hand!
