Can the router table serve as a joiner?

Can the router table serve as a joiner?
Can the router table serve as a jointer?
Can the router table serve as a joiner? About 6 years ago I
was preparing a technical manual on a router table and the
manufacturer insisted that it could work. I set it up and was
amazed at how well it worked. Now you can see by the pic at
right that I have not abandoned my 6" long bed joiner, but in
the pictures below I will demonstrate how it is done.
If your router table has a split fence as does this one from
Woodhaven, it is a simple matter of loosening the screws on the
left hand side and slipping in shim material. I use a scrap of
Formica in which I have cut slots to go around the screws. There
are many ways to shim the left hand fence out. For me, using
Formica is fast, simple and accurate. I just slide the shim in place
and re-tighten the screws.
With the router unplugged, I install a straight cutting bit.
This one has a pattern bearing which is useful for setting the
depth of cut accurately but you can use any straight bit. The
bearing isn't used but for setup.
Project - Stickley Style Writing Desk - "Making the Top"...continued
I now shift the fence system to the router table . It takes
about 7 seconds, too. It really is that fast to shift from one
to the other about the same time as I used to take to walk
from one station to the other. Not bad.
I clamp in place the jointer fence that I made. (If you
didn't read that section, click here.) Since I am adding
this fence to the Incra TS-III saw fence, I have added a
few spacer blocks to allow room for the bit.
With the router unplugged, I lock the shaft and use the
bent wrench to tighten the collet on the trim bit.
I lock the 1" insert ring in place.
The hand crank gives me very quick height
adjustment. I lower the bit to fit within the fence cutout.
It is very nice to make height adjustments without having
to work from under the table.
I bring the outfeed side of the fence to be level with the
bearing of the trim bit. The Incra TS III's micro-adjust
knob makes precise adjustment very easy.
I run all the boards through the jointer. I have wedged
a vacuum pick up between the fences. This type bit
exhausts its dust behind the fence so a vacuum pick up is
necessary in some form. I plan to make a fence that
includes a dust collection port coming soon.
The boards look good and tight.
My next step is to cut slots for biscuits. I mark each of
the joining boards at four points along the length. Note
that I have flipped the boards over. The bottom sides are
up now. I want this side up when I cut the slots. That way
the top side will be down and flat to the router table. If
there is any discrepancy in thickness, the top, at least,
should be nice and flat.

Project - Stickley Style Writing Desk - "Making the Top"...continued
Earlier in the week, I had time to figure out how to use
the router table for making biscuit joints. (If you haven't
seen that page, click here.) Now is the time to use what I
learned.
At the router table, I install the 5/32" slotting cutter. As
with all the bits, I press the bit until it seats in the collet.
Remember, I have placed two "O"-rings in the collet to
serve as the spacer that is required. (This was discussed in
an earlier site - click here to go there.)
I place the auxiliary fence on the table and set the router
bit height to the opening. This fence opening was cut for
centering the slot on 3/4" stock, so this should work fine
for the table top.
The Rout-R-Lift height adjustment is very fine. Turning
the crank one revolution raises or lowers the bit 0.05".
This makes fine tuning the bit height a breeze.
With the bit in the opening, I know the fence is
centered so I clamp it here. Note that I have added spacer
blocks between the auxiliary fence and the Incra TS III
fence. This allows for me to wedge a vacuum pick up in
between the fences. As I said earlier, I plan to make an
auxiliary fence that will connect directly to the dust
collector.
I use a straight edge to align the cutter's bearing with
the edge of the fence. Using the Incra TS III's microadjust knob (insert) is so much easier and more exact
than "nudging with a hammer."
Even in this very dense oak, it takes no time to make
perfect biscuit slots on all the edges. Remember, the
bottom of the table is facing up. The table top is face
down on the router table. That should give me perfect
alignment on the top face even with boards that may
differ slightly in thickness. We will soon see.
At my work table, I have set the top panels in order on
two Bessey K clamps and am now starting to glue.
As I finish brushing the glue on the edges and the
biscuits, I piece the boards together with hand pressure
only at this point. The PVA glue has quite a long "open"
time approximately 15 to 20 minutes. That is plenty of
time for this table top to be assembled.
I only want to clamp with enough pressure to get some
squeeze out. The boards were so well fitted, that more
pressure isn't necessary. Over-tightening will weaken a
joint.
The top is glued up. Note that I have added a third
clamp on the other side. These boards are very well
aligned and are not cupping, so this third clamp isn't
really necessary but is good to do as a matter of practice.
It does make it possible to stand the assembly up while it
dries.
With a damp cloth, I wash away the squeeze out. I can
do this with out negatively effecting staining later on,
since I will not be using a penetrating stain. I will discuss
this more when I start the finishing process.
I will do the legs, with sliding dovetails, next week.
SuperStation Project - Stickley Style Writing Desk - "Legs and Sides"
This picture says a whole lot. First, in the background,
note that I have a Performax thickness sander that I
would normally use for sanding the glued up desk top.
I chose, instead, to use a cabinet scraper because it gives
a finer end finish. Secondly, the top was so flat, that little
scraping was required. Lastly, I am trying to do this
project sticking to the SuperStation. To use the
Performax would be like Norm* going to his $14,000
Timesaver wide belt sander not really fair for the rest of
us. So scraping I did. and I enjoyed every minute of it.
* No ill meaning towards Norm. On the contrary, I love what
he, and the New Yankee Workshop, has done for
woodworkers.
I cut the width of the desk top using the sliding table. I
said last week, that this top does not get any edge
treatment other that the slightest round over, which I will
do later on.
Cutting the legs to length is a breeze, too. It helps to be
using the fence stop the table should stand level with four
equal legs.
Last week, you will remember that I practiced making
sliding dovetails. I use the practice cut-offs to help me
determine the length that I should cut the sides. I have
carefully set the blocks back 2" from both edges and am
now measuring from dovetail to dovetail. This way, I
don't have to measure and then calculate setbacks, socket
depths and all. For me, this is a much safer way.
To the SuperStation. I start, by moving the Incra TS
III to the router section. By the way, I am following the
exact same procedure that I did when making the test
cuts (click here for that section.)
I will show much of the steps that I used today but not
in the same detail as last week.
I am going to start by installing the 5/8" dovetail bit
that I used last week. I won't make the dovetail cuts yet,
but I want to use the bit to help me "zero" everything to
where it was last week.
And, yes, just one picture using the bent wrench, my
favorite tool.
I lock the insert plate in place.

SuperStation Project - Stickley Style Writing Desk - "Legs and Sides"...continued.
I add the Incra router fence to the TS-III fence and
center it over the bit.
I could have used the settings I came up with last week,
but, instead, use my sample piece to set the fence to the
correct distance and the bit to the right height.
Once the fence is positioned and locked, I adjust the
scale to zero.
Before I go much further, I mark the insides of the legs.
This decision is purely a matter of aesthetics, but I don't
want to be cutting sliding dovetails on the wrong sides.
Since the sides are the same width as in my test of last
week, I use the sample block also to set the Incra Stop.
Using a good sample, like this, does make things simpler
and, hopefully, foolproof. Good wood is expensive. I don't
want to make any errors at this point.
I have backed the fence off (that is why I set it to zero)
and have installed a 3/8" straight bit. I will use that to cut
most of the groove, before I use the dovetail bit to make
the final cut. With the fence's zero point marked, I can
move it back to change bits and, then, return it to the
exactly right point without fear of error. To me, this is a
real benefit to the Incra System repeatable accuracy.
I cut the groove, with straight bit, making several
shallow passes. I have used the Rout-R-Lift's hand crank
to adjust the bit down from the final height. In doing this,
I have counted the number of turns of the crank. I went
down exactly 10 turns from the set height, and now I keep
track of the turns as I raise the bit and make the passes.
When I have added 10 turns, I know I have reached the
right height.
Note that I am cutting only the one groove on each leg. I
will complete this one and then reset the fence and do the
other.
After I have cut the straight groove to depth, I switched
to the dovetail bit and made one pass. Even in the dense
oak, the dovetail bit cuts smoothly. It would have done
nothing but burn if the straight bit hadn't done its work
first.
There is no way to get around this two step method. The
Rout-R-Lift and Incra System make the task very easy
and accurate.
With the one dovetail groove done on each of the legs, I
use my sample block and move the fence to the other
dovetail position. I lock the fence here and reset the scale
to zero.
I then repeat the operation of cutting several shallow
cuts with the straight bit, followed by the dovetail cut.
So here I am making that final dovetail cut on the last of
the four legs. Even with all the setting and resetting, this
leg cutting operation took about 20 minutes. What I like
best about it is that it is a safe way to cut the legs, and
they came out perfectly.
Now it's time to cut the sides to fit.

SuperStation Project - Stickley Style Writing Desk - "Legs and Sides"...continued.
I have ripped the sides, front and back to 3 1/2". The
final measurement will be 3", but I wanted to allow for
possible tearout when cutting the dovetail rabbets, and I
want some extra width for cutting the front more about
this in a minute.
Here, I am marking the backs of each board. You can
see at the right, there is one small knot which barely
shows on the other side, so I will place it on the inside of
the back. For the most part, this is very high quality wood
with no bad spots to consider.
I purposely left the dovetail bit at the height that it was
when I cut the dovetail grooves in the legs. Now, I am
using a scrap of wood to adjust the fence to zero (the bit
just brushes the block.) Once set, I move the fence exactly
1/8" on the scale. I will make the first rabbet on both
sides with that setting. From my test run last week, the
rabbet was a bit over 3/16" on each side. Making this
rabbet in two passes will make the cut easier and will
reduce the chance of tearout.
I use my shop made jig to hold the piece securely
against the fence. I was hoping to do two pieces at a time,
but the jig was narrow by about 1/2".
Fact is, doing all four pieces, both ends and both sides,
took only about 5 minutes.
Then I adjusted the fence 1/16" and made the final cut.
As in the test last week, it took a bit of nudging with the
micro-adjust knob to get an exact fit. Once perfect, It
took another 5 minutes to make all the cuts again
To make the rabbet cuts at the haunches, I was able to
clamp all four pieces together. A couple of passes, and I
was done.
Time to get back to the table saw and cut the pieces
down to final widths. I do like the way the Incra TS III is
easy to switch between stations and the stops are very
accurate. I have not had to recalibrate the fence to the
blade since I first set up the system that is good.
Before I go further, I will say that I did remove the
blade guard so that you can see these cuts.
Earlier, I said that I would explain the cutting of the
front. I want to have two side-by-side drawers in the
front, so I will rip the bottom rail (1/2"), the 2" drawer
section, and then the top rail (1/2"). Ripping and keeping
the pieces in order allows the front piece to keep the
original grain orientation. Remember, I cut the piece
wider (3 1/2") to allow for the kerfs and a bit more.
Here I am cutting the bottom rail. I am using the
pushstick that I made. It is exactly 1/2" wide and rides
the T-tracks in the Incra TS III fence. I don't like narrow
cuts, but this setup allows me to keep control over the
stock all the way pass the blade.
Having set the fence to 2", I start the ripping of the
center drawer section. I will cross cut this piece a little
later when it's drawer making time.
My last cut is the rip of the top 1/2" piece. Part of what
makes ripping safe, is to have a sharp and clean rip blade,
a perfectly aligned fence, a polished table top and firm
control of the stock all the way through the cut.
(Note: I will admit that what I am missing is a good
splitter with anti-kickback palls. I will remedy that soon.)
Thanks to the accuracy of the Incra fence system, I end
up with a front that is a total of 3" wide. The pyramid
markings allow me to keep the pieces in the right order.
By the way, you are right that you can barely see the cuts
that is a sign of a good ripping setup.
I reset the fence to 3" and cut the sides and back. Note
that the dovetail haunch is against the fence. I don't want
to cut that off by mistake.
Well, that is where I will stop with this project for this
week. But we did start another project - the Standing Bar
a fun project that uses the SuperStation and more.

Next New Project "The Bar"
Then, install the router and adjust the fence so that the left-side
of fence is in exact alignment with the straight bit bearing. The
gap between the straight edge and the right fence should equal
the Formica shim thickness. Be sure to move the two fences as
close as possible to the bitas a matter of practice, I leave about
1/8" space around the bit.
Now I can plug the router back in. (By the way, I do unplug
my router every time I change bits. Adding handy switch
boxes and outlets makes it easy ... and saves my back.) I plug
a vacuum cleaner into one outlet so that the on/off switch
controls both the router and the vacuum and sawdust removal
is almost automatic.
This combined photo should tell it all. I feed the stock from the
right keeping the board against the right-hand, infeed fence. If
the left-hand, outfeed, side is set properly, the board will fit
snugly against it as it leaves the cutter. The inset photo in the
corner shows the straight down view of the cutter, the cut and the
infeed and outfeed planes.
When I am joining boards, I first place them together and
mark the boards with a light "arc" witness mark. Then, I run
one board with the mark down and the other one with the
mark facing up. This way, if the router is not exactly 90o, the
joint will still be perfect. I do this when using the jointer as
well.
The two boards have a great matching edge the entire length
after just one pass. The router table as jointer does work. As I
said at the beginning, this doesn't mean that I will sell my jointer...
but it is always nice to have various ways to do the job well. And
for those people who are building their shop, this method can be
employed until they are ready to purchase a jointer.
Here I am using an 8 foot level to guide me in setting height
of two roller stands. They can be very useful to support the
weight of longer boards.
"A tour with Beth of the features and benefits."
Router used as jointer it's built in...
While we are discussing the fence, there is something
really neat designed into it spacer bars. These bars are of
two different thicknessses and can be inserted in the track
between the fence and the outfeed side.
This allows the outfeed fence to be "proud" by a
fraction of an inch (1/32" or 1/16") what this really
means is that the router can be set up to edge/joint boards.
Let's watch Beth set this up.
Beth has installed a trim bit in the router. It has a
pattern bearing the exact size as the diameter of the bit,
itself.
She loosens the 2 screws on the outfeed side fence.
She places two spacer bars in the slots of the fence.
Since there are two different sizes, she makes sure that
the two spacers are of the same thickness. In this
example, she is using the thinner bars that will allow a
thickness of 1/16" to be removed. It may take several
passes, but since she is jointing white oak, removing less
will be easier on the router and will give a smoother end
finish.
Now, she tightens the outfeed fence.
Beth adjusts the fence until the outfeed side lines up
with the pattern bearing exactly.
This is a birds-eye view of the setup. You can see the the
pattern bearing and outfeed fence are aligned, and the
infeed fence is back a fraction.
Now she can route a board and have an edge that is
ready to glue up with other edged boards.
I found two boards that had rough edges good ones to
try out the "router-as-jointer" system. She is inspecting
these boards and sees that they are pretty good but are
not ready for gluing. They both have rough sawn edges.
Beth, keeps the board moving with gentle pressure
against the fences. This is heavy, white oak, so she makes
the pass slowly.
It took two passes, but she ends up with a nice edge...at
least, it looks nice.
This it where it counts. Beth now has a very tight joint
one that will glue up nicely.
"A tour with Beth of the features and benefits."
A step-by-step of changing bits.
Beth was familiar with procedures for changing bits on
the other table. She asked to be guided through the
procedures for this new table.
[ Note: If you are a "pro", this SOP may be too
simplistic and detailed; you may want to just go to the
next page.]
She starts by unplugging the router.
She uses the little hook I taped to the plug and hangs the
router cord on the shaft lock knob.
She pulls up the fence's pivot pin knob and rotates the
handle to keep it in the up position. This allows her to
move the fence back a bit.
She lifts the insert from the table.
She gets the bent wrench from its storage place. [What
would you do? Would you have hung this on a hook on
the side of the cabinet?]
With her right hand pushing in on the shaft lock knob,
she can use the bent wrench to loosen the collet. [I don't
know any router other than the Hitachi M12V that allows
you to loosen, or tighten, the collet with 1/4 turn that
makes it very special for the router table.]
She places the bit in the bit drawer.
From the bottom storage compartment, she brings out
the CMT/Sommerfeld Junior Raised Panel Set. So far,
that is her favorite, and we just got some new plans for
desk accessories using these, so she wants to get them set
up with the new system.
She uses finger pressure to bottom the bit in the collet.
[Important note: only do this when you have a rubber
spacer in the bottom to prevent the bit shaft from touching
the router shaft. If you want to read more on using Orings to serve as a spacer, click here.]
http://www.woodshopdemos.com/table-8.htm (3 of 3) [09/09/2008 12.38.04]
"A tour with Beth of the features and benefits."
A step-by-step of changing bits...continued
With the bit "bottomed", she pushes in on the shaft
lock knob and turns the bent wrench until the bit is
locked in the collet.
She places the smallest insert that will give the bit
proper clearance.
Question: can you identify what the bent rod in the
foreground is for?
Beth starts to change router height. She turns the
remote height adjustment lock 1/4-turn. The rod with the
white knob is the adjustment crank for the RouterRaizer
that I installed last week. (Click here to go to that section.)
This is how easy it is. With the shaft unlocked, she uses
the crank to adjust the height of the bit to match the
sample that she has been using. When it is right, she
simply turns her right hand, and locks the shaft.
The RouterRaizer has a small metal dust cover which
fits into a hole over the access to the height adjustment
screw. The crank has a small magnet which is used to
remove the dust cover for easy access. It stays in place on
the magnet until the height adjustment is complete, and it
can be "swiped" off as easy as it was to pick it up a very
neat and workable device.
With the bit changed and the height set, Beth doublechecks to see that the shaft lock is disengaged. She now
unhooks the plug from the knob.
She plugs the router cord back into the switch box.
Note that the power cord for the dust collector is also
attached and is switched on and off with the router.
She places a brand new insert into the fence slot. The
junior raised panel bits are ones that benefit from using a
zero clearance insert plate, so it is worth the effort to
make one.
She starts to cut the profile in the fence by easing the
fence into the router with the router spinning. She is
careful to stay behind the fence for this operation. The
fence is pivoting on the end with the adjustment screw.
The pivot pin is retracted for this cut.
With the router stopped, she marks where a space for
the bearing and top nut must be cut.
Cutting the insert to her marks is quick and easy.
With the insert cut to allow for the bearing and top nut,
she can complete routing the zero clearance fence.
She will loosen the entire fence slightly and move it and
re-cut to widen the opening. The insert should be loose
around the bit. I prefer to cut it until I have about 1/8" all
the way around the cutter.
[Note: before turning on the router, always be sure to
rotate the bit by hand to ensure that the cutter clears the
insert.]
Beth brings the fence forward until the bearing is
absolutely aligned with the fence and locks the fence in
place.
She is ready to make her cut. On the last two pages, I
have presented the step-by-step in great detail. In real
time, changing of the bits takes about 1 minute, even with
following all the safety rules. Cutting a new insert takes a
couple of minutes longer, but only has to be done for a
new bit and then only if you want a zero clearance insert
for that bit.
"A tour with Beth of the features and benefits."
Beth finally gets to use the new router table for routing.
She uses the push pad method that she has used before
guiding against the fence. Having the miter track means
that we can use it when it makes sense, but it doesn't
mean that it makes sense for every cut.
The zero clearance insert proves a great help in cutting
the small rail pieces.
She inspects the cut it is a perfect coped end. Now she
can switch cutters, cut a new insert and do the other
profile.
We skipped to the final cutting of this mating profile,
but for information sake, it took less than five minutes to
make the whole change, including cutting the new insert.
Here Beth is making the profile cut on the rail and stiles.
As an aside, we get so caught up with doing things the
same way, time after time, that we forget that there are
other ways. I have watched Marc's demonstrations and
have always liked this simple holddown block. It just fits
this one piece, but is so simple, it would make sense to
have a number of sizes around.
On ours, I have added a piece of 120 grit sandpaper to
have a more positive hold on the work piece now, back to
the story.
The pieces match perfectly, as they should with such a
really great set-up as this.
I said a minute ago that we would be using the miter
slot when it made sense to use it. Beth and I have gotten
very skilled using small holddown jigs that guide against
the fence.
Here, she tries out a standard miter gauge to which we
have added the hold-down accessory (Delta).
Beth sets up to make a cut and decides that using the
fence will work better. This miter gauge just doesn't have
the support where it counts.
When I heard that the new table would have a miter
track, this Delta Sliding Shaper Jig (photo from the Delta
website) came to mind. I have seen it used on shaper
tables, and it seems like it would work well.
There are two problems that I found: 1) it is around
$100 and 2) it has a 1/2" thick base plate which means the
router bit has to come up that much further. This is easy
to do on a shaper; not easy with a router.
Beth is looking over my shopmade "equivalent." It uses
an Incra miter slide. I like these because they are
adjustable to the miter slot you can make then travel
easily or with a push...you can even lock them in place.
I have adjusted this one to slide smoothly in the table's
miter slot but with no play. I may trim off the length. It
isn't necessary for use of this jig, but right now I will
leave it long until I settle on the design.
I have used a piece of 3/4" white melamine for this
prototype. Once I have it "refined", I will use phenolic it
machines better and will keep its shape. The white
melamine jig will probably warp in time
Beth's left hand it at the area that will hold the
workpiece. I have dadoed this area to about 1/4"
thickness and have added sandpaper to hold the wood.
I dadoed a groove for the adjustable clamp bar and
attached that with machine screws that are countersunk
from the bottom.
It works and it works well, but we use the fence set up
most of the time. It is a good jig to have, and the phenolic
version will be better.
I am going to close up this presentation...time is running
out. I do have some hold downs that are in the works that
will make great use of the T-tracks. I will add those soon.
I also have some Board Buddies that I need to convert for
use here.
I can say, that both Beth and I are eager to get started
using this really fine table/fence system on some real
woodworking projects. All this, and more, will be added
next time.
