Also get or make an arrow spinner so you can check to make sure there is no wobble in your arrows.
If you really want to get into building your own arrows get a mini cut off saw from Harbor Freight they are about 25 bucks and work like a dream.
I have one rigged up I will take a pic and post it.
What is an arrow spinner?
Also I would be interested in the link to the cutter you mentioned and also a pic of your set up with it (or a pm would work)
Thanks
