Shorty BH
« on: September 18, 2020, 11:46:52 am »
My new bow is 52 NTN. Do I still go with a 6" BH(approx) or do I scale it down? The only other time I've made a short bow was for my grandson and I reduced the BH.

Solid source ;D Did he hold them in a particular way to avoid wrist slap?

I don't think so. I know from experience if you rotate the bottom of your bow hand out away from the bow a little you can avoid some of it. Primitive man almost had to of used arm guards (and I know some did) or they built some pretty big callouses on there arms :D

I really overestimated the amount of wood I needed for this. I've got a tight long string on it and I'm pulling 35#@ 5". I think I have to watch it as I have a feeling that when things start to move, they'll move fast.

You can find pics of  half eye shooting with a slight crook to the elbow and wrist which keeps the arm well out of the way.  If any part was hit it would be the base of the thumb.

 Since you are likely using no stretch the chances of being hit decrease greatly.

 Reducing the brace height relative to bow length makes sense.

A question. I'm tillering away with the shortest long string I can get on. It's pulling 35#@ 8". A long way to go and the limb is getting kind of thin. It crosses my mind that I might be able to get 50# instead of 35#. I pulled it to 40 something and changed my mind. Now it feels soft so I pull it to 35#. It goes to 14". I'm thinking lots of set, I screwed it up. So I measured the reflex and it's still within 1/4" of where it was which is 1/2" higher than when I took it off the caul. The bow seems fine it just took a jump from 8" to 14" without doing anything. Is it possible for a bow to take set, as in lose DW without losing any reflex. I thought measuring the reflex was a good way of checking for set. Puzzled.

DC did you trace the bow off the caul. IT took set just happened mid limb in or the tiller was perfect and the entire limbs took set. Maybe Arvin

most of the time set is considered the permanent deformation, or visible change in limb profile, so I suppose not.

But if you are asking if the wood has been compromised, then yes, the stiffness has changed. Think of Badgers "no set tillering". It's a method to detect the change in stiffness that precedes visible set taking.

Yes I did and right now it shows more reflex along the full length of both limbs than it had right off the caul.

It seems like a lot of change but in the absence of anything else that must be it

 (lol)

Overpulled and not even to brace yet... I sympathize.

Have you been keeping track of the weight at various draw lengths? Badger's method works great, but the problem is it shows me as soon as I have screwed up, but too late to avoid it...

I took a closer look on the tree this morning and noticed a bit of a weak spot. Is it possible that on a short bow the effect of a little screwup is magnified?
I do think that I should have made a caul especially for this bow. I just slid the bow toward the tip end of the caul but by the time it's braced there is not a lot of recurve left. I'll finish my coffee and fly at it.

 Ok DC was the wood dry? I will hush and learn. Arvin
