Do some searching, as mentioned there are some great step by step tutorials out there.
If you don't have a spinner, just use a cordless drill, that's what I do and works pretty well.
Personally, this is how I do it. For my 40# bow, I used 45-50lb Port Orford Cedar (POC). For my new 47lb. bow, I just bought some 50-55lb POC, but haven't made the shafts yet. I have a 28" draw and use 125gr. points. If you use heavier points, or want to be able to leave your shafts longer, then you may want to use 55-60lb. shafts.
My process:
* Taper nock end of shaft
* Straighten shafts if necessary (roll on granite counter to find the high spots, then use a screw driver shaft to rub the high spot against the counter, repeat until straight enough)
* Stain entire shaft (any wood or leather stain)
* Tape off where I want my cap to stop.
* Dip, or spray paint (enamel) my cap.
* 1 coat of sealer, I use gasket lacquer and a dip tube, but you can also use a rag and wipe on poly
* Straighten any shafts that went wonky during the dye/paint steps.
* Chuck shaft into cordless drill and use a vise to pull the trigger.
* Crest with Testors model paint.
* 2 more coats of finish
* Glue nocks onto all shafts
* Point taper 2 shafts and apply points with hot melt glue
* Shoot arrows at target from 5 yards, moving to 20 yards if they are shooting straight.
* If shafts fly and impact target with the nock pointing left(for right handed shooters) then your spine is too light. Cut 1/4" off and re-taper and add point. Repeat this until the shafts fly and impact just as straight as a normal arrow. (If you get too short that your point is touching the bow at full draw, then you need to start with heavier spined shafts)
* If shafts fly and impact target with the nock pointing right then you bought shafts that are too heavy in spine, and you gotta start all over with lighter shafts next time
You can do the above with all your arrows, but for my purposes it's close enough to just tune 2 or 3 arrows then cut all arrows to the length of the tuned shafts.
* After all shafts are cut to length and have points on them, and fly well at 20 yards, it's time to fletch.
* Using a fletching jig and fletching tape, Fletch your arrows. I like to add a drop of glue to the ends of the fletching when using the tape.
