I grew up dorking around with the cheapie tube-band wrist-braced slingshots, and never really liked them. The fact you couldn't buy replacement bands around where I grew up might have helped with that thinking, but also, they didn't look like "real slingshots", like the ones Dennis, Bart, and all the others used <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"> .<br><br>I'm big on marksmanship, and where I live currently, I'm not able to go target shooting on my property. I found The Slingshot Channel on Youtube, and realized "now THIS looks like a fun hobby, and I can enjoy it in my back yard! Not once every couple months at the range, but every single day if I wanted!"<br><br>I'm looking to build a multiplex/plywood slingshot, maybe even 2 or more, under the assumption that the multiplex panel I'm likely to get at the hardware store will furnish multiple.<br><br>I have a few questions.<br><br><strong>1.) </strong>I'm a fairly fit person, so I'd like a slingshot that is capable of adding a little bit of exercise to the fun. Joergs 'Phoenix' design from his how-to video looks very nice, but I see his Hammerhead is also very popular. What are the best all around strong/heavy duty multiplex designs for a beginner to build?<br><br><strong>2.)</strong> I understand that my band lengths and whatnot will depend on what kind of shot I intend to shoot. I know slingshots are not an ideal self defense weapon or zombie skull perforator, but I like to dream! If I want to get proficient with a slingshot, I might as well make it one that can take small game, give zombies a brain case leak, and at least irritate the future new world order mega armored laughy bang bang clown army.<br><br>What is an ideal projectile for the velocities a vaguely beefy slingshotter can achieve? I'm guessing lead .45cal?<br><br><strong>3.)</strong> What is multiplex likely to be called at my West Coast USA hardware store? I gather 'multiplex' is the European term?<br><br><strong>4.)</strong> If I build my slingshot tuned to shoot a specific lead or steel ball, will I also be able to noodle around with pebbles as ammo, or should I build a dedicated pebble slingshot for that purpose, as the "ammo" will likely be both larger and less heavy than my metal round shot?<br><br><strong>5.)</strong> I believe a draw weight of 50lbs or more should be no problem for me. Decent upper body strength and all that. However, I imagine there has to be an upper limit of what extra bands can achieve, otherwise you could put 50 on each horn and play dink the can with the international space station. What's a proper number of bands for a powerful slingshot without going pants on head stupid?<br><br>Thanks in advance!
