pappy, sorry i did not weigh them before i mounted them.  i'm making another one as we speak and i'll make sure i weigh it first.  since i make them using nothing but sandpaper, it takes me a while to finish one 

thanks bob, that's why i was asking about alternatives.  i thought about my heat gun too, but i can't find the friggin' thing 

  maybe i should join the "big project" thread and clean up my basement.
edit: pappy, i just weighed the arrows and they are 27 to 28 grams (416 to 432 grains)
