Title: How to tiller an unequal limbed selfbow?
Post by: tahirsdt on July 31, 2013, 07:50:21 pm

Hi

Ive been making a hickory selfbow which has unequal limbs, the upper limb is an inch longer, all has gone well so far but im at the tillering stage and I am realy confused on how to go about it or how the tiller should look, I should have started with equal limbs for my first bow but I have gone so far that I dont want to turn back. Please could someone help!

Thanks

why not just take an inch off the top, and be done with the issue?

Tiller it so the upper limb to string measurement is around 1/8"- 1/4" more at brace height. Fine tune it so the amount of stringfollow the bow takes is even in both limbs or slightly more(up to 1/4 "more follow in the upper limb). Its not an exact science especially if you're making a self bow.

Alott of us on here make bows like that, usually I just make the upper limb physically bend a greater distance. Since the upper limb has more material (because it's longer) both the limbs will proportionately have the same amount of bend even tho the longer limb will bend farther.... i really hope that made sense, that's how i understand it lol.

stats on the bow would help. length? bendy handle? drawlength?
with only an inch difference, it shouldn't really change the tillering much- just make sure that at brace, the handle and string are paralell.
