The Goal
Better organize part of my home studio by building custom-fit studio rack furniture
to house two of the keyboards (Ensoniq TS-12 and Roland D-20), studio monitors (speakers),
and about 14 rack units worth of gear. When finished the keys of my larger keyboard
should be 28 inches (711mm) from the ground (like a grand piano). Small footprint
and quick & easy construction. Target price: less than US$100.
Note: The studio rack furniture I had built previously provided for a U-shaped studio
design, which simply would not fit in the apartment (flat) we were moving to. This one takes
up only as much space as absolutely necessary.
Tools? Drill, screwdriver, a couple of dowel hole alignment markers,
and rubber mallet (optional). That's it. Literally. =)
Before I get started, let me show you how it ends. Below is the completed furniture.
(Excuse the ugly wallpaper -- it's not our fault.)
 Completed deskThe Design
After measuring all the equipment, I settled for a design using two floor boxes
each holding eight rack units with space at the bottom for "stuff." My keyboard
controller, the weighted-key TS-12 straddles the two boxes and another thin shelf
(bridge) sits above it to hold my old D-20 and the speakers. This design also allows
the width of the unit to change based on personal preference and makes the piece
easier to transport-- important because I was about to be moving cross country.
(Why was I building furniture right before a big move? My wife didn't know either. . . .)
The rack openings are 19 1/8 inches wide (486mm), which allows an oh-so-tiny bit
of play side-to-side. I used to build racks with 19-inch (483mm) openings, which
meant a tight, clean finish, but no room for error. The choice is yours. For more information
about rack standards, including photos, see All About Racks & Rack Rails.
IMPORTANT NOTE:
Five pages of detailed plans for
this studio rack design in PDF format, including a plywood sheet layout plan (cutting
diagram) are available for download FOR ONLY US$2.

 Front view
On the side view you can see I left room to stick my head in behind the base
units and fiddle with wires. There's also a back brace that doubles as a support
for deep and heavy rack units (like my sampler). The piece is not at risk of tipping
over, because the bottom board extends back the full distance and the TS-12 provides
a lot of weight over the front. (Note: The back feet somehow didn't make it into
this image, so just pretend they're there -- they look just like the front feet
but they're in back. =)
 Side view
Made from 3/4-inch (19mm) cabinet-grade plywood, this piece is quite solid and stable.
And it looks good, too.
I have several other designs with detailed plans available online, too. Lots of
do-it-yourselfers, and a few complete novices have built these pieces successfully.
For more information, see Recording Studio Workstation & Rack Plans.
Here's some of what's available:
Here are a couple of thumbnails of the plans:
The Plywood Sheet
All the pieces fit nicely onto a 4-foot by 8-foot sheet of plywood (1220x2440 millimeters).
You can get these sheets of plywood for as little as US$20 if you're not concerned
with quality. I chose "cabinet grade" birch plywood with two good sides for US$55.
Birch stains nicely, and it's easier to find matching edging tape (more later).
Download the plans for the most current version of this layout.
The cabinet-grade plywood was a bit of a splurge -- I could have saved a bundle
by using a lower grade or less expensive "generic" plywood . . . . or even particle
board or MDF for that matter, but I strongly recommend plywood instead. It's sturdier,
doesn't bend as easily, and holds screws MUCH better. It also looks a lot nicer
when finished.)
 Plywood cutting diagram
Since I prefer to have someone to blame when something goes wrong, I had the wood
milled at the place where I bought it. Milling wood is very precise and costs about
US$1 per cut, plus there's usually a set-up fee. It's only offered at some lumber
yards so be sure to ask before you buy. Cutting out these pieces totaled US$20.
The PartsParts List| 1 | 4x8 3/4-inch Birch Plywood I could have saved more than $30 here if I settled for a less "premium" wood! | $54.98 | | 1 | Plywood Millwork | $20.00 | | 1 | 50-ft Birch Wood Tape (Edge Banding) (I used about 30 ft.) | $9.94 | | 1 | Sandpaper | $2.91 | | 1 | Set of 16-space Rack Rails (Blow-out price at Guitar Center!

So, about US$5 over budget, plus tax -- but I used a nice birch plywood, so if I
really wanted to cut corners I could have built it all for about US$75. Plus now
I have extra screws, dowels, wood tape, felt pads, and sandpaper left over for my
next project. I already had the wood stain, so I didn't add that in to the total.
(NOTE: Mega-stores like The Home Depot tend to have lower prices than smaller stores,
but they usually do not have milling services.)
Where do you go to get these parts? Ask your local hardware store if they provide
precision milling services. If not, ask them to refer you to a place that does.
Buy the plywood at the same place you get it milled, but you'll probably want
to buy all the other hardware at The Home Depot or a similar home center or mega-hardware
store -- they tend to have great prices since they're bent on putting local hardware
retailers out of business.
Finally you can pick up the rack rails at a local Guitar Center, online at Musician's
Friend, or see if you have a local pro audio store nearby. I happened to find an
amazing deal on the rails -- usually rails come in 2, 4, 10, 12, 16, and 18 spaces
(not 8) and range in price from US$3 to US$27. To make two sets of 8-space rails,
buy a set of 16-space rails for about US$25 and cut each side in half with a hack
saw. You can get a cheap hack saw for about US$5, and it only takes a minute to make
the cut -- it's actually a lot easier than you might think. For more information about rack
rails and standards, see All About Racks & Rack Rails.
You can get good deals on rack rails from stores that supply computer hardware rack-mount
accessories, or check Amazon.com to see what's available.
You can also often find standard 17-inch rack rails on ebay for about a buck-a-U
(for example, a pair of 16-space rails for $16).
Preparing the Pieces
The first thing I did was judge which pieces would go where -- including which sides
were most presentable. I marked each piece with its location and orientation with
a piece of masking tape. An example marking is "Left Base Unit, Left Side. up-^,
forward->, (out)" which tells me that the piece is the left side of the left base unit.
The side with the tape should be facing out, and the "up" and "forward" arrows indicate
orientation.
Next I ran wood tape (edge banding) across all the visible edges. Edge banding is
a great invention because you just iron it on to the edges and then trim off the
excess. It sticks forever -- or at least for more than 10 years (when I started
making this stuff).
If the banding starts to peel up in places before the glue has dried,
simply put a piece of paper over the edge to protect the wood, then "clamp" the
edge banding down with a piece of masking tape.
Great mod:
A customer in Florida finished the tops of his desks (base units) and shelves (bridges)
by first painting the surfaces black, then gluing on inch-thick pieces of wood trim
to cover the plywood edges. He rounded over the trim with a router, and when he
stained and finished workstation, it had a very classy appeal!
Finally, I chose to sand and stain the wood. I found it easier to stain the wood
before assembly. Staining is easy -- just rub the stain on, then wipe it back off
again and let it dry. Your hands will get messy and so will your clothes, so it's
a good idea to wear gloves and be. Also, be sure to properly dispose of the rags
-- they can spontaneously catch fire if you're
not careful. (Edge banding, by the way, tends to be a little blotchy when stained.)
 Staining the pieces
I rewrote the piece names and orientations on an edge that would not be visible
on the finished product.
 Writing on the edges for identificationInstalling the Feet
Install the adjustable-height feet by first drilling a hole and then inserting
a plastic fitting that's threaded on the inside so the feet can turn and go in or
out. I measured carefully so the feet would be 3/4-inch (19mm) from each bottom
edge (the hole had to be 1 1/4-inch (32mm) from the edge because each foot had a
1-inch (25mm) diameter.
 Measuring for foot placement
Be careful not to drill through the board! I used a depth stop just to be safe.
You can see it attached to the drill bit in the photo with the drill just below.
Another common trick is to make a depth gauge by simply wrapping a bit of tape around
the drill bit at the depth you want -- just be careful that the tape doesn't slide
up the drill bit as you drill more holes.
 Installing the feetGreat mod:
Several customers have used casters (wheels) instead of these adjustable feet --
especially when adding on to some of the other plans. You can get a reasonably good
deal on casters at your local home center, just keep in mind that the smaller they
are, the less likely they are to roll well on carpets. Casters also add height,
which may or may not be a bad thing. It's common to put a pair of fixed-position
casters on the back corners of the floor unit, and a couple of swivel casters on
the front.
Installing the Rack Rails
To install the rack rails I slid them up to the very top of the side piece, and
inset them 1/4 inch (6mm). I could align the rails accurately with the help of a
scrap board placed at the top edge of the side board (as shown in the photo) and
a couple of C-clamps.
Be sure not to directly clamp your good wood! I use pieces of wooden paint stirring
sticks or other scraps of wood as a buffer to protect the workpiece from the clamps
when necessary.
Here's a trick:
Several customers have saved a few bucks by using solid oak (or other hardwood)
trim instead of rack rails. I personally prefer the look and fit of the rails, but
I expect there is some grounding benefit to using wood.
 Clamping the rails in place.
Tighten the clamps gently, then nudge the rack rail around until it's in the perfect
position, then tighten the clamps to secure the rack rail in place. Predrill the
holes with the rail in place (again using a drill stop so you don't go through the
board) and use the thickest 3/4-inch (19mm) screws that will still fit through
the holes on the rails. I used #14 sheet metal screws. (Sheet metal screws are threaded
all the way to the head of the screw, which I like in this case for extra holding
power.)
 Pre-drilling holes for rails.
I used four screws to fasten each rail.
 Attaching the rails with screws.Great mod:
A customer in Michigan had even less space than I did for this project, so he made
his base unit racks even narrower by turning the rails around and fastening them
so the lip used to mount the gear hung in front of the plywood edge. If you do this,
be sure you cut the top and bottom pieces carefully to the narrower width so the
holes are still 17.75 inches apart. And be sure the holes are far enough away from
the edge of the wood that the ends of the screws don't end up getting buried in
the wood if you don't want them to (he did, actually).
While I was at it I marked exactly where the top of the back board was to fall.
This board serves two functions. First it stabilizes the piece when there are no
rack units installed. (This was important to me because the pieces will be supporting
two expensive keyboards, regardless of whether or not they're filled with gear.)
Second, the board can provide additional support deep and heavy rack units installed
at the bottom of the rack rails. A deep and heavy piece will extend beyond the 12-inch
(305mm) wide sides and will lay nicely on that supporting beam.
 Marking for the placement of bracesAssembling the Base Units
Because the weight of the rack gear, keyboards, speakers, and shelf will all fall
on the joints connecting the sides of the base units to the bottoms, it's crucial
that it be as strong as it can be. For this reason I planned to use wooden dowels,
wood screws, and even L-brackets to strengthen the joint. (I later determined that
the L-brackets were not necessary.)
 Illustration of braket and dowel positions.
It's a bit difficult to see, but the placement of the wooden dowels and screws alternate
in the image above: four screws and three dowels.
Start by drilling the holes for the dowels into the edges of the plywood, both on
the bottom board and the back support board. You'll want to drill into the edges
first because the nature of plywood (layers of various densities and types of woods)
make it much more difficult to position the hole accurately. Often the drill bit
will slip a bit and end up going into a softer layer of wood than the center layer.
(This is okay unless the bit comes out the side!)
Here's a trick:
If you're fortunate enough to own a biscuit joiner, this part of the project will
go a lot quicker and with a lot more accuracy. But even with a biscuit joiner, I
still prefer dowels -- they offer a much greater sheer strength. You can also invest in a
doweling jig, which will make it far easier to get the holes lines up perfectly on the
edges of the boards.
Drill all the holes for the dowels then insert metal dowel pins (or dowel alignment
markers). When the board with the dowel pins is pressed up against the board it
will be fastened to, you'll get small indentations marking exactly where the corresponding
hole should be drilled. (Again, use a drill stop set at about 1/2 inch (13mm) to
be sure you don't go through the wood.) When you press the boards together to mark
the corresponding holes, use scrap pieces of wood to help align the boards (such
as is shown in the Rack Rails section).
 Marking the locations of the dowel holes.
You'll end up with each side having five holes that correspond perfectly to where
the dowels will be.
 Drilling the dowel holes.
If you're using the standard 1 1/4-inch (32mm) dowels, sink them 3/4 inch (19mm)
into the edges of the backs and bottoms of each base unit. You can add a couple
drops of glue first if you want, but I don't think it's really necessary.
 Inserting the dowels.
Then attach the sides. You'll probably find it easier to have an extra set of hands
for this part. First attach one side to the bottom, then attach the back piece to
that same side. Ask someone to hold those two pieces up for you while you attach
the second side. If the dowels don't seem to fit right away, then just keep trying
-- perhaps by lining up a different dowel first. Even if they're off a little you
can usually get a good fit. Wood is quite flexible!
 Assembling the base unit.
Once you have the base together (except for the top), set it on its side on an old
towel or carpet. Press down firmly on the other side to be sure it all fits together.
If there's a gap that just won't budge, you may not have drilled enough room for
the dowel, or the dowel may be badly mis-aligned. If this happens, find the offending
dowel and just redrill it -- or move it over slightly to one side or the other.
Adding the Screws and the Top
I used four screws on each joint. Space the screws out evenly for a nice finished
look, and be sure you're not intersecting pieces of hardware. In other words, there's
not much point drilling a screw in through where the dowel went, or worse yet, hitting
the threaded metal feet with a screw you put in from the side.
Measure carefully and mark with a pencil where the screws should go lengthwise across
the joint. For a 12-inch (305mm) joint, I put the screws at 3/4", 4 1/4", 7 3/4",
and 11 1/4" (while the three dowels were at 2 1/2", 6", and 9 1/2"). In metric units,
that's 19mm, 108mm, 197mm, and 286mm, with the three dowels at 57mm, 152mm, and
241mm.
 Measuring for screw placement.
Next go back and be sure your dot is exactly 3/8" (9.5mm) from the edge since this
will land your screw right in the middle of the 3/4" (19mm) plywood edge. I usually
dent the wood with the pencil tip to make a starting point for the drill bit. Remember
to wear safety goggles -- a pencil point (or wood or anything) will hurt when it
hits your eyeball.
 Measuring the edge for screw placement.
There are two pieces of wood you're joining here -- the one the screw is going through,
and the one the screw is anchoring itself into. You should always predrill your
holes in the "anchor board" with a drill bit that is the diameter of the core of
the screw (without the threads). This makes it a lot easier to place the screw and
protects against splitting the wood. Ideally, you should predrill the "through
board" with a bit the same diameter as the shaft of the screw nearest the head.
(Wood screws have a point, some threads, a shaft, and then the head.) If you do
this, then the boards will "pull together" as you tighten the screw. I'd venture
to say, that it's not completely necessary, though, if you can manage a tight fit
when you go to sink the screw. (I usually put my knee up on the board to be sure
the wood is pressed together firmly.)
In any case, to predrill, set the depth of the drill bit to the length of the screw,
make sure the joint is firmly seated, and drill the holes.
 Setting the bit depth.Here's a tip:
You can achieve a more professional look by drilling countersinks. If you have one
available, grab a drill bit about the same diameter as the head of the screw, and
start your pre-drilling by drilling a very shallow cut in the "through board" with
this bit -- just enough so that the heads of the screws will be flush with the surface
of the wood, or ever so slightly below. (You don't want these to be too deep as
to compromise the strength of the joint.) It's usually easiest to drill this part
first, then follow up with the rest of the pre-drilling.
After the holes are drilled, the screws should drive in quite easily. "Dry fit"
the pieces by pressing them together firmly and making sure the pilot holes line
up. Then when you're ready to join the boards forever, run a bead of yellow glue
along the joint if you want (not essential), and start fastening the boards. Be
sure the pieces are pressed together firmly. It's hard to re-do this part if
you mess up.
 Screwing the base unit together.
You can attach the top of the base units with screws in the same fashion. I didn't
use dowels for the top because the board sits atop the side pieces, which provide
ample support for the weight of the gear.
Do one side at a time and the pieces should line up just fine. It's okay if it's
a little bit off; just nudge the pieces into the correct position before you drill
the holes and plant the screws. When the base is finished, check to make sure it
sits evenly on all four feet, and adjust the foot height if necessary.
 The completed base unit.
Repeat the process to build the second identical base rack.
The Shelf (Bridge)
I designed the keyboard bridge to fit snugly around my Ensoniq TS-12 without interfering
with the cable placement in back. The shelf is deep enough to support the feet of
the top keyboard and long enough to hold the top keyboard and the speakers. It was
designed to overhang the bottom keyboard by a few inches (centimeters) while still
allowing someone seated at the keyboard to clearly see all the buttons and displays.
Great mod:
A customer in California built a "cable gutter" along the back of the desk to hold
cables and power cords that might otherwise be dangling.
I used three screws each to fasten together the legs of the shelf in much the same
way that I fastened the sides of the base units.
 Assembling the bridge supports.
I planned to use dowels to attach the legs to the under side of the shelf, so I
drilled four dowel holes into the edges of each leg first. After inserting the dowel
pins into the edges, I used another piece of scrap wood and a C-clamp to ensure
accurate positioning before I pressed down to make the drill marks.
 Setting the placement of bridge support feet.
After drilling the dowel holes into the bottom of the shelf, I touched them up a
bit with an Exacto knife to remove the splinters. (Remember to use a drill stop
or depth gauge.) Yes, that "Exacto knife" part is totally unnecessary and is a clear
illustration of my OCD. =) After all, these holes are going to be covered right
up! Why on Earth I felt like they needed to be "cleaned up," I have no idea!
 Cleaning up the drill holes.
I then assembled the shelf using just the dowels to hold the pieces together. I
can remove the legs if necessary for easier transport. On the bottom of each shelf
leg, I stuck a felt pad. Since the shelf will sit "floating" on the two base units,
the felt pads will help protect the base unit from bumps and scratches.
 Adding protective felt pads.The Result
Now I have a brand new, space-saving piece of home studio furniture designed and
built to my exact specifications. And it only cost me US$105.
 The completed workstation.
The alternative would have been two eight-space racks of questionable quality for US$90
each, two milk crates for added height, a two-tier keyboard stand for US$50 that may
or may not hold the weight of the keyboards (the TS-12 is HEAVY!) and may or may
not wobble when I play. All this and I still wouldn't have room for the speakers.
