I love heavy wood shafts, i like to do an oil soak for days on end in a homemade dip tube! My last attempt i used some KK German mountain pine shafting 65/70 spine! I cut/tapered and gave a light sanding and a hand straightening before putting the entire dozen into the pvc dip tube! Check daily topping off oil soak! After a wk of soaking, i take 'em out and dry 'em for a wk! i then do a few hand rubbed coats of urethane! My 30" shafts went from 450gr before soak to 525gr after, fletching and with a 160gr point i have about a 675-680gr finished arrow wt! Thats goin to be my hunting arrow for a while as ive made 3doz of them!!!
