I drill a pilot hole the size of the 'barrel' of the screw. -I always use a combination drill bit for sinking screwheads. The first part of the bit is the diameter of the 'barrel' of the screw and the step, one inch higher is the size of that screw's head. (The barrel is the diameter inside threads) -I have a set of these drill bits for #6, #8, and #10 screws and they are great.

How do you place spindles on a hand rail?
This depends on ones skill; but the easiest technique for a do-it-yourselfer is to set the handrail in place first. Spindles or balusters with square stock on both ends would do best. Place the spindles, usually two per step, so they will be spaced evenly from step to step. Scribe a line on the upper square stock of the spindle from under the handrail. This will give you the angle of cut for all spindles; but you should check to insure that all lengths are the same. Even a 1/16th of an inch will make a difference in the spacing of spindles. Set the bottom square stock to the step or tread. Drill a pilot hole with a countersink drill into the upper square stock into the hand rail. Insure that this pilot hole is drilled on the upper side of the staircase. I would recommend a #8 countersink drill and #8 screws, at least 2" in length. Continue up the staircase and good luck. Enjoy your great job.
