building a horsebow

[peter61]

Hello Tradgangers!
When building a horsebow (glass-laminates-glass), is it necessary to take tapered lams or can I use parallel lams?

taperede lams will make the limbs bend more midlimb and out. Parallel lams will tend to focus more of the bending near the fades.

You could probably go either way. Check out supertiller ... it s program which analizes limb profile and taper to determine draw weight and drawen and strung profiles. That might help you get the full draw and strung profile you are looking for.

Ive searched far and wide for the super tiller program but cant seem to find a version that is operational. Anyone have a link or download?

I've found Supertiller to be really finicky ... it runs fine on some computers and not well on others. Haven't been able to figure out why. I've got an older laptop running windows XP I keep for running supertiller and some similarly basic open source boat design programs.

You need to enable macros in excel before you open supertiller.
