Installing Iron Balusters, Images 1-6

Double widths of masking tape protect the treads; the baluster locations go right on the tape.

I use a laser to transfer those locations to the underside of the handrail, then drill holes in the rail 3/4 inch deep and about 1/8 inch wider than the diameter of the baluster tops.

In looking for a way to install the balusters one at a time instead of all at once, I realized I could drill slightly oversized base holes with two smaller holes on each side to accommodate the tip of the epoxy tube.

To lay out the hole positions on each tread, I use the metal shoe that the balusters fit into as a template.

After marking the outside of the shoe, I drill the two 3/8-inch-diameter nozzle holes so that they go all the way through the tread and penetrate the stringer by about 3/4 inch.

I use a spade bit to drill larger holes for the baluster itself, sizing the hole so that it is about 1/4 inch larger in diameter than the baluster’s base and penetrates the stringer by about 3/4 inch.
