>Leaf from a car suspension.
i know people usually suggest this, and I've never tried it,,,,, but I don't think it would work.

for example: at local farm stores they sell replacement leaf springs for small trailers. the SMALLEST ones are rated for 1000 lbs,,, and a car weighs much more than that.
now,,,,,,, the mini-trailer packs are 3 leaves. you could take the pack apart and just use the largest leaf (the one with the eyes in the ends) but I still think it would be about a 500-lb pull bow.

what I would suggest as something easy to make, is not to use a spring-bow at all. use a rigid bow (a piece of 2 x 4 wood with a big hook in each end) and use surgical tubing as part of the "string" instead. (pic related) All the parts are at the local hardware store and don't cost much, and you can use as many loops of surgical tubing as you want--to make the bow weight as high or as low as you want.
