Stair-Building Tools - Continued
Once all the treads, risers, and newel posts were installed,
we started piecing together the handrail. For all of this work,
we used an assortment of tools and templates — and,
believe me, stair building requires a lot of them.
The over-the-post fittings we used on this stair were from the
Conect-A-Kit system from L.J. Smith (L.J. Smith Stair Systems,
740/269-2221, www.ljsmith.net). If you're a beginner at
building balustrades, like we were, these fittings make stair
building easy because the tops pop off on all the level
fittings, and the bottoms pop off on the easings
(9). With the top off, you use a standard
socket set to drive the connecting lag screws
(10).
We also had a lot of standard railing connections to make. To
lay out the rail-bolt holes, we followed the advice in L.J.
Smith's catalog and made templates for everything. A plastic
template made it easy to locate the center of each 1-inch hole
in the bottom of the railing and rail drops
(11). For the 3/8-inch holes in the ends of
the railing sections, we cut a thin slice of railing and
drilled a 1/8-inch hole at the centerline and used that as a
template (12). We used a 1-inch Forstner bit
and a 3/8-inch paddle bit to bore the holes (13,
14).
RAIL CONNECTION TOOLS
L.J. Smith's Bore Buster Plus kit ($500) comes with a variety
of tools that make balustrade installation easy for any
experienced trim carpenter, even if your experience doesn't
include stair work. To assemble the rail, we used the Rail Bolt
Installer (15). This handy little wrench has a
1/2-inch socket on one end for tightening the hex-head lag
screws that are the primary fastener for the L.J. Smith system.
A nut welded to the center of the wrench works great for
tightening 5/16-inch rail bolts, which are the industry
standard for rail assembly and are also used on several
connections in the L.J. Smith system. The wrench is also gauged
for locating pilot holes on handrails and rail drops, so
rail-bolt connections are easy to align — a fact I
didn't realize until later, after I'd made my
templates!

We actually discovered another wrench for tightening rail
bolts that we liked even better (16).
Universal Building Systems' ingenious device, the Rail Bolt
Wrench ($8, 800/200-6770,
www.stairfasteners.com) is made from
heavier steel, and has a magnetic stud on the handle designed
to hold the nut while you thread it on the bolt. A common
rubber band wraps around both the nut and a pin in the center
of the handle (17). By simply pulling on the
rubber band, you can spin the nut onto the bolt
(18). I had a tough enough time just seeing
inside that 1-inch hole. I couldn't imagine threading on a nut
without that wrench.
MAKING A PITCH BLOCK
In addition to the special pop-top fittings, we also used a
few standard easings on this staircase. To make the necessary
cuts on the easings, we turned to the tried-and-true pitch
block, on Jed Dixon's advice. A pitch block is a deceptively
simple device, and easy to make: One leg equals the height of
the tread (the rise), and the other leg equals the width of the
tread (the run). The resulting angle — the rake
— allows you to find the tangent points where the
railing parts meet.
First, we positioned the pitch block with the rake against the
railing (that's the angle of the stair, which is also the angle
at which the railing runs up the stairs), and marked the
tangent point on the bottom of the railing (an easing in photo
19). Then we turned the pitch block around and
traced the angle of the rake across the railing profile
(20).
We used a shortened pitch block at the miter saw to help
secure the railing at the correct angle. A couple of Quick-Grip
clamps and a spacer cut to fit between the bottom of the
railing and the miter-saw fence made the operation a lot more
precise (21). Jed warned us to first dry-fit
all the pieces and then, to make a perfect fit before final
assembly, shave a little off the railing, not the easing. It's
a lot easier to cut a piece of straight railing than a curved
easing. As it turned out, almost all the pieces fit perfectly
the first time — no doubt the result of good advice,
patience, and clamps and jigs.
