I use the carbon express shafts as well.
I use the harbor freight cut off saw.
I then use the G5 square up tool for the cut off end and the 5/16 reamer tool with tee handle to rough up the inside of the shaft for gluing the insert into it.
Next blowout the carbon dust and clean with q-tips and denatured alcohol.
I use insert iron glue for the brass inserts.
I fletch with left wing 5 feathers using fletching tape.
Idoubted the tape over fletch tite glue at first, but found it to be just as strong and way faster to use.
I only need one bitz and left wing jig and am finished quickly since I no longer wait for glue to set.
Sometimes I use the One Stringer wraps and sometimes I do not.
I haven't tried wood arrows yet, as the cresting part is what keeps me from jumping into that.
Maybe some day.
But as for carbons...it's a lot of fun and you can build them for friends and family...make nice gifts etc.
Costwise, I don't keep track, but doing it yourself will feel good for you.
Have fun!
