I also have no arrow saw. What I have done is use a drill, fine toothed hacksaw blade, and a knife. I chuck the arrow nock end in my drill (with a layer of masking tape for protection), mark the intended cut, and take a deep breath. lol. Then grasping the knife and arrow tip, I carefully line the knife, arrow tip mark, and give the drill a quick pulse. This cuts the top fibers so you can continue the cut with the fine toothed saw blade held the same way as the knife. Reverse the drill for the first few turns before turning towards the saw teeth. It's alot quicker to do than to explain. I use the same technique in cutting fishing rod blanks in my rod lathe. I'm sure there are better methods developed by the experienced arrow makers in this forum, but there's my 2 cents. Good luck.
