I hand taper them by taping off the tip leaving about 5/8" exposed. Just taper that part of the tip as the top half of the hosel is .370. I use a digital caliper to measure, so I sand, rotate, sand, rotate, measure, sand, rotate, sand, rotate, measure, dry fit, etc until the caliper says .355 and it fits the head snug. I sand with a strip about 1/2" wide using the shoe-shine stroke. Clean the hosels real good all the way down and epoxy with glass beads added. When you install the shaft, rotate it as you go in to spread the epoxy evenly, once you have the graphics where you want them, turn it over, and while holding the club by the head, tap the butt end of the shaft on the floor (I hit it 5 times, HARD) to jam that tapered tip down into the head.
If you are removing steel shafts and installing graphite, and you care about swingweight, you might want to butt trim 3/8" to 1/2" longer to get them back to D0, or whatever they were. This will add about 1 degree of upright to your lie angle too.
