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
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
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
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!
If your not satisfied with the range just add more rubber bands but not to many or you could snap th frame
