today I'm building a staircase with a custom handrail
but before we get to the build
let me get you up to speed about what needed to be done on the jobsite
before we can install the stairs and handrail
here's the before picture which the clients felt was a dated design
it was not going to go well with their new
Hickory flooring that they were installing at the top of the stairs
they wanted to update the style of the staircase to an open-ended tread
to do this I needed to modify the wall
so I drew the rise and run of the staircase on the drywall
I then took my sawzall and carefully cut out the shape
unfortunately the treads were dadod into the skirt board so I had to demo them
and cut new stringers
I only demod half the staircase so I'd have something
to stand on while I worked on the other side.
after the demo was done the corners
of the drywall were just flapping in the wind ready to snap off with a little pressure
to solve this I reframe the wall up in sections
then I slid them in between the stringers and drywall nailing them off to the existing studs
but before I demo'd anything I fabricated all the components back at the shop
while I can order custom sized treads the millwork shops in my area didn't offer the customizations I needed
to wrap around the existing walls
so I just fabricated my own
for the treads themselves it was your basic milling to thickness and gluing together operation
but for the nosing I milled up some eight
quarter stock and chucked a stair nose bit in the router
before I ran the stock through the router I clipped off the corners at the table saw
this helped reduce the load of the router especially using a huge stair nosing bit
It also considerably reduced the chatter and tear out on the Hickory which is prone
to having a lot of tear out when routing
then at the router table I used several
feather boards to help keep the stock tight to the fence and tight to the table
This resulted in a perfect bullnose that needed very little sanding
once all the pieces were bullnosed I cut the miters for the open-ended treads on
the table saw
for most of the treads it was your basic edge banding operation with mitered corners
but for the bottom tread I had to make a notch for the new post.
I first attached the center nosing with dominoes and glue
I then went back to the table saw and for safety I cut a mitre on a longer
piece of nosing and then cut the piece to length
I pre-glued the mitered corner before attaching it to the tread
this made installation a bit easier so all I had
to do was tac the return in place with some brads.
I milled the test block the
same width as the new post and did a quick test fit
to be sure I had a nice fit
it's much easier to adjust the edge banding before the glue fully sets
now on to making the new post. I ripped down some eight quarter stock and laminated
two pieces together.
Once the glue is dry I ran it through the planer until it was
down to the thickness I needed
to give the new post illusion that they have
floating panels I milled up some stock and ripped a miter down one edge
I sent up a stop block on the table-saw so I could quickly cut them all to the
same length then I glued the miters together to create the corners for the new post
These were long and skinny, to skinny to clamp,
I used some blue tape to hold them together while the glue dried.
once the glue has set up enough to take the tape off I used a card scraper to
remove the excess glue squeeze-out so the corners would fit tight to the post
Before installing the corners I pre finish the post themselves
this would be a lot easier before the corners are installed and also help prevent any raw
wood from showing along the edges if the wood shrank during seasonal movement
Then as an extra precaution I ran my block plane and down the sides
chamfering the corners to be sure the corner trim would sit tight to the post.
To install the trim I used a headless pin nailer. it was big enough to hold the
trim in place but small enough not to have to putty a bunch of holes
there are three rail elements to the post. One at the bottom one two-thirds up and one at the top
this design element came from the doors in the rest of the house
that had the same panel design
I started out by marking and cutting each piece as I work my way around and up the post
when installing the middle rail I used a spacer block to be sure they would all
be placed in the same spot and to save a bunch of time
not having to measure for each one
The last detail for the new post was to build the cap. There were a few test cuts
involved and a bit of math to get all four sides to meet in the middle at a
nice clean point
I didn't record it because at the time I thought it would
make for a boring video. If there are enough people interested maybe I'll go
back and recreate a video for the future but the operation itself is pretty
straightforward I used my shop made vertical sled to
clamp the workpiece and with the blade raised to the correct height and angle
When I made the cuts I cut the cross grain first as it's more likely to tear out and
then I cut with the grain second removing any tear out from the cross
grain cut
I reset the saw blade to 90 and then cut the decorative shoulders on the top side
the cap will be pinned in place with a brad nailer and a little glue and the
underside will be trimmed out with quarter roun.
I did the same order of operations here
I cut the cross screen first and then I cut with the grain to
cut off any tear-out that may have happened
while the stain and finish was drying on the new posts I moved on to prepping the
stock for the spindles I joined it planed and cut each spindle square there
are 20 spindles in this project plus some extra stock to create the little
cross braces between each spindel so this took some time
next was to cut the little angle of cross braces that were going between the spindles
since my table saw is old-school and doesn't have a proper riving knife
I clamped a shim just so it rubbed the back side of the blade
this way as I cut the little parts
they were pushed away from the blade preventing them from becoming a little kickback bullets
a stop block clamped to the miter gauge made the cuts accurate
and quickly repeatable
While I had the miter gauge set up at the right angle I
cut the tops of all the spindles this angle is going to go against the handrail
then I Re-squared the miter gauge to cut the lower cross braces that
are going between the spindles I set up a stop to make the cuts repeatable but I
took it one step further I set the red arm as the stop so the
metal bar would act as a hold down
this made it a little safer more comfortable
to cut the little parts
now it's time to cut the joinery I know a lot of people
poopoo the Domino because they think it's not real woodworking or it costs
too much or they just love to hate something but for a small custom shop
like mine when I need to get a job finished before the next mortgage
payment is due the Domino is the way to go
there was 72 of these little cross
braces so I think the Domino paid for itself that day
to set up my jig I screwed it down to the table and set up some angled stop blocks to hold the
workpiece in place and a stop block to my right to register the Domino against
this way the mortises would all be in the same place
for the spindles themselves I reset my jig so I'd have something to climb to
then I set a stop block to the left and right to register for both the upper and lower
cross braces
then for the very bottom cross braces I reconfigured the jig one last time to
cut the mortises on both sides
you may have noticed that these parts are
stained and finished. I wanted to pre finish the inside edges before
assembling this as it would be really difficult to stain and finish after they were assembled
to assemble the spindle units I screwed yet another jig to the
table the stop block as the top of the jig is cut at the same angles and rise
and run up the stairs to help me quickly align all the parts at the proper angle
now all there's left is to add Domino's clamps and glue
I clamped it in a way so I could simply lift the assembly off the jig set it aside and start clamping up
the next set
to attach the spindles to the treads I simply doweled them
so once the assembly was dry I routed out a slot in the bottom of the spindles
to receive the doubt to do this
I screwed a jig to the side of my assembly table
to connect the spindle assembly upside down so I could route out an
oblong hole in the bottom of each spindle the reason for the oblong hole is it
gave me a little wiggle room in case one of the dowels in the treads was off
once the glue is set all three dowels would be solid
The reason why I'm blowing
out the hole there is my spiral up cut bit was so dull it made more smoke than sawdust
so I'm using a spiral down cut just to get the job done and it is
driving the chips to the bottom of the hole
I should also mention that big chunk of walnut scrap is only there
to take up the extra space in the clamps
this makes it easier to clamp the workpiece without the bar sticking out in the way
once everything was installed I had one more detail to take care of and
that was the cove on the backside of the treads and risers
my local millwork shop
did not stock Cove and hickory and they charged in the $200 setup fee for a custom run
I only needed a few sticks so I was back at the shop to mill some up
Since Hickory is a splintery wood and a router will often tear out a big chunk of wood
instead of cut it. I did a similar operation as the stair nose to prevent
tear-out and reduce the load on the router
I used the dado blade to remove the bulk of the material then set up feather
boards on the router table to route out the cove
since thin pieces will chatter while milling I used a wider piece of wood than I
needed to make the cove. I'd then rip the cove free at the table saw
this let the router cut a cleaner Cove and is much safer to waste a little wood than to try
to route a little piece
I should mention for the handrail profile I did
have my local mill workshop custom cut it. That was large enough and complicated
enough to justify a custom run over my labor to mill it in-house
so here are some shots of the Finnish staircase and handrail
if you're going to take on a project like this I highly recommend you pick up a code book
in my 20-plus years of working in the trades I've had all kinds of people tell me
what the building codes are and more often than not they're wrong to one degree or another
you'll save yourself all kinds of headaches
