Arrow length

(1/3) > >>

DC:
Just reading about Dan's(Alans) 24" arrow. And realised that the shorter the arrow, the lighter it is, but also the stiffer it is so it may be possible to reduce the diameter leading to lower weight. This made me realise that it's the speed of the arrow as it leaves the bow that really counts so it's acceleration that is important. If we can get the arrow to dry fire speed in 6" we could use really short dense light arrows. There's got to be something I'm not thinking about. What limits the length of the arrow?

Badger:
   Don, there is no such thing as an arrow shooting at dry fire speed. Dry fire speed is just that, dry fire. The further you draw the bow the faster it will get. It is often advantageous to use shorter arrows and shorter draw though because of the difference in weight and stiffness. We have a minimum legal arrow length of 23". This can''t be draw any further than 25" using a 2" shelf.

DC:
Thanks Steve. I've got a couple of short staves. I may try something.

Del the cat:
My Osage flight bow was originally 24" draw for all the reasons stated in the original post. It did pretty well, but taking it to 28" has shot it further. I think there's a sweet spot and anything over 28" certainly starts to get floppy or heavy.
Dunno where the sweet spot is tho' , doubtless depends on the bow too.
There are control issues with short draw... my mate JT who is used to shooting 32" has been bruising his bicep trying to shoot 95#@28".

Selfbowman:
Well I under built a 70# bow and cut it from69" to 60" trying to hit 70 # it started taking set at about 50# at 26#  so I stopped . Building a couple 23-24 test arrows. Test results still out. I figured this was all I was going to get out of this design and bow. The force draw also started to go the other way , meaning smaller differences per inch of draw. Not sure about this but when it peaks it peaks. Arvin
