Bareshaft tuning is the same whether they're wood, aluminum, or carbon. With wood you just have to make sure the shafts are straight and matched for weight and spine first. I make a matched set of 1/2 dozen, only fletch 3 of them, and leave them all an inch or so long. Shoot groups at 15 yards, shorten as required,or adjust side plate/plunger or brace height. In your case with a selfbow having arrows a little on the weak side is probably good, but a 160 gr broadhead may be too much.
