How To Build Custom Kitchen Cabinets from Scratch: Step-by-Step Guide

You can find great reward in creating your own custom kitchen cabinets but you need the right tools to start. The project risks becoming costly because you lack the essential tools and knowledge needed when you try to complete it alone.

Problems arise when cabinet frames do not line up properly while the overall structure feels unstable and drawer alignments fail to be precise. Also, the facing material breaks apart from stress exposure. Your kitchen value could suffer if you have faulty cabinets, plus you could face safety risks because heavy pantry cabinets would not be properly secured to walls.

Before beginning your plywood work and assembling the dado stack, make sure your DIY project readiness assessment proves positive. If you input wrong data, your work will start from the beginning and drain your budget plus add more tasks to handle. My focus here is going to be on the joinery and construction of the custom kitchen cabinets in Austin, including face frames. Let’s take the start. 

Building Upper Cabinets

So the basic parts of an upper cabinet come together pretty quickly with dado joinery, and with a thirty-six-inch cabinet like this, you can handle that at a table saw with a dado stack. Just remember to adjust your dado stack to precisely match the thickness of the plywood you’re using, ensuring that the joints fit snugly from the first attempt.

Now, before you assemble your cabinet, make sure to cut the rabbet on the back to receive the back panel. It’s just 3/8 ” wide and the depth needs to match the thickness of your plywood. Just focus on making the parts flush at the front of the cabinet as you glue the frame together.

Now, obviously, the cabinet doesn’t have much strength or rigidity yet, and that won’t change until we add the face frame assembly and the plywood back panel. But the next step is actually to add mounting cleats. Each upper cabinet gets two mounting cleats and since these will show inside the cabinet, I took the time just to edge-band the one visible edge. These are just plywood strips and we’ll pocket-hole them in place.

So now our cleats are set flush with the rabbet to receive that back panel in a later step, and the upper cleat gets installed in the same way for making affordable custom cabinets in Austin, TX.

Building Lower Cabinets

To build the lower cabinets, you’ll need a single dado and then a rabbet to receive the 1/4″ back panel. This is all simple joinery you can handle with a dado blade at the table saw.

Here the dado intersects the rabbet at the same blade depth—making this beginner-friendly joinery. Even if it’s your first go at plywood joinery on the table saw, you shouldn’t have any issues.

Next, it’s time to lay out the toe kick, which measures 3 1/2″ by 3″. A few key points to remember for building custom kitchen cabinets in Austin:

  • The toe kick should stay well below the dado
  • The dado starts 4 3/16″ from the bottom of your cabinet panel
  • You can cut the toe kick with a jigsaw, but a bandsaw with stop blocks makes it faster and more precise

Once the toe kick is cut, you’ll begin assembling:

  • Install the lower shelf into the dado
  • Add a 3 1/2″ wide cleat at the back, flush with the rabbet, to support the back panel
  • Attach a wider rear cleat for added rigidity; this connects both side panels and the first cleat
  • Finish by adding a 3 1/2″ wide front cleat, flush with the front edge of the cabinet
  • Use spacer blocks on this front cleat to ensure consistent spacing for drawer openings

Joinery Tools and Techniques

A jig will certainly get the job done for large projects, though it does become a little bit tedious—clamping and moving the jig for each new hole. I usually get a little bit tired of that and I picked up a Kreg Foreman pocket-hole machine that makes the whole process much quicker and easier. Just because it has a built-in clamp.

You’ll have to decide for yourself whether the scale of your kitchen cabinet project warrants a machine like this. One feature it does have that’s quite nice is the stops, so you can accurately locate the holes on the end of the face frame rails.

Building Face Frames

For your kitchen cabinet project in Austin , you’ll need to decide whether you’re going to make individual face frames for each cabinet or whether you’re going to do it the style of a custom cabinet maker, where you just build a large face frame to span multiple cabinets.

And that’s what we’re going to do—just make a larger face frame. It’s a little bit easier to lay out and build that face frame, but you do want to have extra people around when it comes to lifting these large cabinets into place.

A key point when assembling face frames is to clamp the parts down to your workbench. That way, things will stay smooth and flush as you drive the parts together. Otherwise, just work around centre marks to get good alignment.

After assembling the face frames, thoroughly inspect both the front and back of the frame before proceeding with additional details for your custom kitchen cabinets in Austin..

Shelf Pins and Finishing Assembly

Let’s drill some shelf pin holes, and my favorite way to do that is with a small plunge router. I usually use:

  • A 1/4″ spiral bit
  • A 3/8″ guide bushing
    This gives nice, clean holes in the side panels.

Now it’s time to add the face frame. In this case, it’s two lower cabinets that have been screwed together and share a monolithic face frame—a large frame that spans across multiple base cabinets, which is my preferred approach.

There are a few ways to attach the face frame, but here’s what I suggest:

  • If using glue and clamps, you’ll need quite a few—sometimes hundreds—to hold everything in place
  • A faster, more efficient method (especially for paint-grade cabinets) is to use glue and a brad nailer
  • For larger cabinet assemblies (like two 36-inch uppers ganged together), simply nail the face frame in place, then:
    • Fill nail holes before priming
    • Optionally flush-trim the face frame with the side of the cabinet, especially if it’s an exposed edge—this gives it a more custom, seamless look

Building Pantry Cabinets

Now by pantry cabinets I just mean an oversized kitchen cabinet in Austin TX, and these are extra tall. The side panels on these are actually 90 inches, and that makes them a little bit too big to handle when cutting dado at the table saw, so just use a freehand router instead.

You will need an exact-width dado jig. You could certainly make a shop-made version of this jig as well—they’re pretty basic to construct.

Use a spiral bit. You’ll get nice, clean cuts in the plywood, and once you’re done, hopefully you’ll have nice-fitting dados. This pantry cabinet has a dado at the top and bottom but also a shelf midway, and that gives it some strength and rigidity.

Just like the other cabinets, this pantry cabinet needs a rabbet towards the back to receive that plywood back panel.

Breaking Down Plywood and Hardware Installation

Depending on your tools, budget, and precision needs for your kitchen cabinet in Austin, there are a few common methods for breaking down plywood and sheet goods in the shop.

Circular Saw with a Shop-Made Straight-Edge Guide

  • Most affordable option
  • Good for beginners or smaller projects
  • Downsides: Produces a lot of dust and the saw isn’t secured tightly to the guide, which can result in less accurate cuts

Track Saw

  • Connects directly to a dust collector, keeping your workspace much cleaner
  • Follows an aluminum track for highly straight, consistent cuts
  • Delivers much better cut quality, especially with veneer products, compared to a circular saw
  • Ideal for those doing frequent or precision cabinet work

Either method works for breaking down your sheet goods. The next step, regardless of how you started, is to trim everything to the final size at the table saw for clean, accurate dimensions.

Final Assembly and Hardware

The pantry cabinet comes together in a similar fashion to the other units. We’ve got three fixed shelves that fit into DADOs in the side panels, and we’ll attach the parts with glue and brad nails.

The next components to add are cleats—you’ll need three, one beneath each of the three fixed shelves. You can even edge-band the exposed part of that cleat as desired.

One of the final details to add on this pantry cabinet is toe-kick cleats, both at the front and the back of the cabinet down on the floor. Remember to drill out your shelf pin holes before adding the face frame on this big cabinet.

I usually use Euro-style hinges now. These have a built-in soft closing feature, and they have a 1/2″ overlay. These ones cost me a whopping one dollar apiece.
