Actually, Steve, it is really quite easy and the aluminum shafts you are shooting are a good place to start. All you will really need are a fletching jig, some feathers and a tube of glue. For the xx75's I recommend Fletch-tite for both feathers and nocks. The bitzenburger is my choice of fletching jigs, but there are several on the market that will do the job just fine. Clean the shafts until they squeak with scouring powder (gently) or a solvent like acetone. With the solvents, wipe them off before they dry on the shaft. If you can find me at the PBS Banquet in Pitts Mar 27-30, I'll walk you thru the whole process.
Fletching your own is absolutely worth the effort and cost.
