This slingshot is heavily based on a slingshot outlined by Joerg Sprave in the video "How to make a power steel slingshot with common tools". I have, however, slightly modified his design to simplify construction and allow for a later upgrade to add a whisker biscuit, which will allow you to shoot arrows with this slingshot (given heavy enough bands - See Joerg's videos to see this type of thing in action).

DISCLAIMER: This slingshot can handle very powerful heavy bands, and therefore this can be a very dangerous slingshot. It can injure and probably kill. DO NOT point this thing at any people or pets. This goes double when the whisker biscuit attachment is added. I take no responsibility for what you do with this thing once you build it.

The above being said....I just might try it out shooting paintballs at some point in the near future...

Step 1: Step 1: Materials

Materials
------------
2 - Simpson Strong Tie T-Plates (With an extra hole drilled in the center)
1 - Hyper-Velocity Slingshot Band Replacement Kit (This was out of convenience...for more power use Theraband Gold or Black)
4 - 3/8" Hex Nuts
4 - 3/8" Flat Washers
1 - 5"? Carriage Bolt (Pick a bold that fits your hand nicely)
2 - 3/8 x 4" Eye Bolts (Sold with nut attached...so really you need 6 nuts total if these are not present)
1 Roll - Black Duck Tape
A few feet of light twine/string (optional)
Krazy Glue (optional)
20 Gauge Hardware Wire

Tools
-------
Most of my tools are in the city at my brother's place since I normally have no use for tools at my apartment. I keep a small amount around just in case, so for this project, I actually did not use all the appropriate tools. I will outline what I used and what should have been used.

9/16" Wrench (Should use 3/8")
Adjustable pliers (Ideally use another 3/8" wrench)
Wire cutters
Needlenose Pliers

It's unbelievable that anyone would use wire to hold bands on. First of all, it WILL eventually cut the bands and they will break. Secondly, when they do break, there's a good chance that wire will come back and strike you in the face and/or eyes. Anyone with even the most basic knowledge of slingshots knows that you never ever use wire. Rubber bands work perfectly and work better than anything else. A constrictor knot doesn't even apply to slingshots even though it's the easiest knot in the world to tie with numerous pictures of it available. "Over the top" is the method used to tie bands or tubing. Even commercially made slingshots that use tubing don't use a constrictor knot. They simply cut a small hole in the tubing and run the other end back through that hole for a clean look.

No, as the cost could be different in different places, and could increase over time.
<p>the 3/8 X 4 Eyebolts, a Home Depot item?</p>
<p>Great idea but I'm thinking that the handle needs to be longer so that there is more distance between your hand and the ends of those bolts hanging out under the T-plate. Either that or you might want to trim off the ends with a bolt cutter and put some rubber caps or plastic-dip the ends of them. For people like myself with bigger hands and a serious grip, it could cause problems with getting scuffed or cut up.</p>
<p>Why does it have to be a T shaped plate? Couldn't it just be a strait shaped plate?</p>
As stated in the instructions, I used a T plate to accommodate a whisker biscuit if I decided to do that down the road. I didn't end up doing that. A straight player would work fine.
I have a heat cured/cooked muscadine vine for the handle that is virtually indestructible to build for grandkids. I wouldn't change anything else. Great job!
<p>Nice! Do you have a list of the cost on parts?</p>
What size of t-plates did you use?
They were standard decking t plates. roughly 5x5 if I remember correctly.
Sweet thank you
<p>Did you consider using cable ties?</p>
<p>I didn't at the time, but they would probably work well.</p>
Nice! Do you have a list of the cost on parts?
I didn't put a price list on as I was writing this because prices both change over time and differ depending on where you are in the world.
<p>Thats wonderful...</p>
<p>great</p>
<p>great</p>
<p>super</p>
<p>great</p>
<p>I see how the author replied, which is reasonable given his hobby of arrowshooting..</p>
