So, Eric...earlier you said you had gone through a bunch of home-made arrow cresting machines. Care to elaborate, possibly on a different thread? I would love to drop the dime on a new Spinrite or Bohning cresting machine, but geez...you could buy quite a few arrows for that sort of dough. I wouldn't mind starting small if you or someone else could show us how to build one cheap just to get my feet wet; that is, unless building one would cost 50%+ of buying a professional grade one. In that case, might be best to just bite the bullet.
Thoughts, anyone?
