Stairs With Routered Stringers
Routering out a hole in
the stair stringer for the tread to insert into is a great way to build
this type of stairway for the interior or exterior. The other way to
build a set of stairs like this is to use
brackets under the stair treads that attach to the stringer with lag
bolts. The only problem with this is that the lag bolts over time could
loosen up creating a stair tread that moves. This will become a safety
hazard later.
With routering out the stringers you eliminate this
problem. The routered out portion of the stringer will create a nice
tight pocket for the tread to insert into. This will keep the stair
tread from loosening up and wiggling as you walk up and down the
stairway.
