This is what I have invested in my arrow building supplies:
1.DAA spine tester-$100
2.Young Feather Burner-$60(used)
3.Dip tubes-$10/each(I have 3)
4.Jo-Jan Multi fletcher-$70
5.Woodchuck Taper Grinder-$140
6.Woodchuck Taper Plane-$100
7.Bohning crester-$50(used)
8.Misc.tools-grainscale,shaft straightener,etc-$20
Plus the cost of points,feathers,nocks,brushes,paints,stains and sealers.Some of the tools you can do without.If you like shooting parallel shafts,you can do without the Taper Plane.You can get fletching jigs alot cheaper,too-I like the 6 arrow jig.The power taper grinder-you can get a hand tool for about $25.And you can buy feathers already cut or get choppers for whatever style fletch you want.You can put into as much as you want-you decide.
