Now u could just pick up a Y shaped stick that u found and use it but it wont be as strong and its more fun to make your own frame.
this instructable is easy to do it will take more than 1 day to build because its constructed with 5 min epoxy so you have to give it time to dry i finished it in 2 days working off and on.
Always use safety glasses when shooting a previous sling design had a habit of firing backwards on occasion, thank god i didnt have contacts back then or id be blind in one eye.
Step 1: Get Your Materials
3 5 inch X 3/8ths X 3/8ths balsa wood (aprox) 2 inch X 3/8ths X 3/8ths balsa wood (aprox) 5 min epoxy (craft/hobby store)4-8 rubber bands depending on size thickness and strechyness stirring sticks for epoxycup for mixing epoxy clamp/vice scissorswire cuter stringcloth for sling (see below)(i just used [http://www.acehardware.com/sm-scott-and-reg-rags-in-a-box-75260--pi-1275301.html Rags IN a Box]) staplerabout a cup of flower(i just used Rags IN a Box) as a substitute for cloth
Build in well ventilated area like out side or garage
always use safety glasses when firing
never shoot a living person tree or animal
(unless your using in paint ball which i dont recommend)
im not responsible for any thing you do if you damage something your self or some one not my fault
Step 2: Cut/glue Frame
cut a 45 angle off 2 pieces of wood
Mix the epoxy
glue the 2 pieces together wait about 5 min and glue the other piece on
with the 2 inch piece of balsa cut 2 pieces with 2 45 angles (see picture) and glue them into place. let dry
Step 3: Reforce Frame Pt 1
you need to re-enforce the frame.
trace the out line of the joint area with a pencil on some scrap balsa repeat like in pictures
glue using clamps let dry
Step 4: Re-enforce Part 2
this uses string and epoxy to make an extremely strong bond.
rap each arm in string like in pictures proceed to rap the rest of the joint area
rap about 2 inches down the handle
Glue, glue each side individually and wait for them to each dry
Step 5: Sling
build the sling using cloth (i just used Rags IN a Box) you could also use an old t shirt.
cut a strip the same thickness as the sling you want and 4X as long as the desired sling langth
fold it in half 2 and cut off the ends
cut holes on each end
glue froward of staples
Step 6: Attaching Sling
Step 7: Fire!
just load sling with rocks, acorns, paint balls. what ever will fit in the sling. hold sling shot in dominate hand, pull back aim let go.
If your not satisfied with the range just add more rubber bands but not to many or you could snap th frame
