Wood isn't suitable for the stresses a compound bow will produce.


I never had a problem with wood arrows in a 55-lb compound. The highest stress point is the string trying to split the grain apart at the nock, which won't happen if you do the fletchings properly.

But yeah, you're better off buying carbon arrows if you just want to practice. They're more accurate at long range, and making arrows takes a lot of patience!


Very bad idea.

You can have 100-130 joules of energy being imparted onto that arrow in a very short time, and there's a huge amount of flexing in that arrow. Aluminium and carbon fiber are so much more suitable for handling this kind of stress.

Uh, have you ever tried using wooden arrows?
The 5/16" shafts I made could be bent in a semi circle before breaking. I know they will never flex that much in flight, because it would be impossible to aim them.

Also, 130 joules is *way* more than my 55 pound bow could ever do. When you look at the F/D graph I don't think it's even possible with a mid-poundage bow.

Also also zeus: don't get plain aluminum arrows, especially from walmart. They get bent up within a few shots and are very inaccurate unless straightened well.

Well, if you're confident in using them and you aren't putting too much stress on them then great. Just play it safe and if you suspect you've damaged one get rid of it IMO.

Ugh... don't get me started on cheap aluminium :roll:
