    After seeing Oldschool's "The Crutch" and the great videos by Bill Hayes, I had to make a slingshot rifle. I had all the parts in my junk pile. The barrel is 1" O.D. conduit. The angle joints and forks are parts from a Tent/pavilion that I found at the scrap yard. The pistol grip is a bicycle head stem. The scope mount is a cheap flashlight mount designed to mount onto a shotgun magazine tube. The red dot scope is a cheap TruGlo 30mm unit. The band set is TB black, 30 cm long, full width at the fork and tapers to 8 cm at the pouch. The draw wieght is 28 lb. & the draw length is 43". I've been shooting these .60 cal lead balls that I painted with florescent spray paint. It seems to whip them with authority. The florescent balls gleam brightly like tracer rounds and they don't get lead residue in my pocket. I'll drag out the chrony and report the velocity. I have yet to make a trigger/clamp but I will. The squirrels don't stand a chance. The weight is 6.5 lbs. Heavy for a slingshot but light for a rifle. What do you guys think? Suggestions?<br><img src="http://img215.imageshack.us/img215/9072/slingshotriflepaintedba.jpg" border="0" alt=""><br><br><img src="http://img823.imageshack.us/img823/9072/slingshotriflepaintedba.jpg" border="0" alt=""><br><br><img src="http://img41.imageshack.us/img41/9072/slingshotriflepaintedba.jpg" border="0" alt=""><br><br><img src="http://img196.imageshack.us/img196/9072/slingshotriflepaintedba.jpg" border="0" alt="">

    Awesome! Will the pouch set all the way to the back to the shoulder piece? Where are you putting the trigger?

    The pouch pulls all the way to the back to the silver handle. That's where the trigger will be.

    Thanks, I did not do the welding. I found those angle/corner fittings mostly as you see them, at the local scrap yard.

    This is impressive!!! I have no suggestions other than to make it look more streamlined, but I'm sure you are way ahead of me and just wanted to give us a sneak peak!<br><br>How is the accuracy and at what ranges? I bet its accurate as hell!<br><br>*wants*

    Go for it bj000, This thing has been a blast. I finally got the trigger/optic block finished and it works great. The loops on my original 25 lb. bandset slid tighter so it's only about 21 lb. now but it still easily shoots a 10mm lead ball right through a sheet metal garbage can at 15 yards. It took about 30 shots to get the sight dialed in. At the moment it will shoot a 2 & 1/2" group at 15 yards. I still need to cut a shallow groove in the under side of the trigger block to increase repeatability/accuracy. Here's the finished trigger.<br><br><img src="http://img406.imageshack.us/img406/9548/heavybarreltrigger1.jpg" border="0" alt=""><br>k <br><img src="http://img535.imageshack.us/img535/8866/heavybarreltrigger2.jpg" border="0" alt=""><br><br><img src="http://img24.imageshack.us/img24/6301/heavybarreltrigger3.jpg" border="0" alt=""><br><br> The white block is a piece of glass reinforced nylon/Teflon that I found at the scrap yard. By the way plastic is usually free at the scrap yard. I wanted there to be a square/flat surface to mount the trigger and rail onto. The sight rail is a cheap weaver rail made for a Rugger 10/22. Costs like $8.<br><a href="http://www.midwayusa.com/Product/959343/ruger-1-piece-tip-off-weaver-style-scope-base-ruger-10-22-matte" class="postlink" target="_blank" rel="nofollow">OpticsRail</a>. <br>The toggle clamp works great. I found them at Harbor Freight for about $5. <a href="http://www.harborfreight.com/200-lb-vertical-toggle-clamp-96235.html" class="postlink" target="_blank" rel="nofollow">HarborFreight-ToggleClamp.</a> <br>The clamp can be adjusted for clamping force and will easily hold the pouch with no ball. <br>To clamp/anchor the block to the pipe, I used a hole saw the same size as the pipe. Then I cut a slot into the cylindrical part to form a wedge anchor/clamp.<br><img src="http://img33.imageshack.us/img33/3165/heavybarreltrigger4.jpg" border="0" alt=""><br><img src="http://img849.imageshack.us/img849/5940/heavybarreltrigger5.jpg" border="0" alt=""><br><br>I then pressed the block onto the pipe and drove/screwed a 5/16" x 1,1/2" lag screw into the 1/4" hole in the block, effectively anchoring the block to the pipe.<br><br><img src="http://img15.imageshack.us/img15/1586/heavybarreltrigger6.jpg" border="0" alt=""><br><br>The original bandset broke after about 100 or so shots so I made another set about 45-50 lb. but I only got off about three shots when the pouch tore. I've got to find some tougher leather. I ordered a cheap Kangaroo hide from Ebay, But It'll take 3-4 weeks to get here from Australia. <br><a href="http://www.ebay.com/itm/pWhole-KANGAROO-HIDE-leather-skin-chrome-tan-Licorice-Swirl-attern-/260861687733?pt=LH_DefaultDomain_0&hash=item3cbc9177b5" class="postlink" target="_blank" rel="nofollow">Kangaroo Hide</a> , <br>On the shotgun tip, I tried a little experiment. I took a 3/8" rod and put it in the pouch and clamped it in the trigger. Then I pulled out the rod leaving a little loop of the pouch behind the clamp. Then I put 2, .32 cal, buckshot pellets in the pouch. I stuffed one in from each side of the pouch. When I fired these at the target from 15 yards, to my gleeful surprise, the two pellets struck the back stop about 2" apart. At that point I was possessed by a fit of maniacal laughter. Needless to say this will be an ongoing project.<br>Thanks again to Bill H. and Oldschool.

    Nice job. You can paint it in black or camo maybe.
