stack in selfbows?
Dan Jones:
A while back I decided to see if I could make a self-bow from board lumber. I have now successfully made several bows from Home Depot red oak and maple boards. I'm pleased with them . . . except for when I take them out to the range. Both bows stack very noticeably in the latter part of the draw. I have assumed that not all self-bows stack, so unless stacking is in fact a characteristic of self-bows, it must be something that I'm doing wrong. The draw weights are both right around 30# @ 28". I draw 28." I backed the bows with linen cloth and reinforced the tips. One bow has limbs that are tapered from the riser to the tips; the other has limbs of the same width down to the last 10", which is tapered. I'm stumped and I will be pleased with any light that can be shed on this question. Thank you.
Terry Green:
No, selfbows don't automatically stack. Stack has to do with tiller.
I'm not versed enough to say much on Selfbows as I have only built 2. I heard for years that your 1st selfbow would fail or come in under weight, so I set out to prove that wrong and did. My 2nd on didn't fail either.
Maiden Voyage - 53@28 when finished, probably 57#s now....
Bear Necessities - 48@28 when finished, probably 52#s now...
Roger Norris:
How long are the limbs?
Dan Jones:
Red oak bow - overall length- 70"- limbs both 30" maple bow- overall length 70" - limbs both 29". I did my best to tiller the bows with Krewson's "Tillering Gizmo."
Terry Green:
Dan, no worries on your tiller. You do the best you can do. You can have the perfect tiller.... but if its tillered to 26"s and you are drawing 28 its gonna stack. Make sense?
Just make sure you tiller it to your draw or little beyond. That's the delicate part.
