While you can do a lot with a hand-held router, you will have a greater degree of accuracy, ease, efficiency and safety if you’re using a router table. The list of processes you can accomplish with a router table includes grooving, slotting, dadoing, rabbeting, moulding, edge treatments, template and pattern work, raised panels, mortising, box joinery and dovetailing.
 
One of the major advantages of a router table is that you’re not dealing with the weight and vibration that comes with a hand-held router. Instead, both your hands are free to manipulate the stock. Routing small, narrow stock free-hand is especially onerous and dangerous. However, on a router table, with the use of a push stick, featherboard, or jig, it’s considerably easier. Likewise, you can undertake repetitive tasks with less time and effort. You’ll also be able to use large diameter bits that are unsafe to use in a hand-held router. And, for many routing operations, you’ll find it easier to align the router bit to lines marked on the stock.
 
Three main styles
Router tables come in three styles – bench-top, stationary, and mounted (typically between the front and rear rails of a table saw). A table-saw-mounted router is an ideal choice for really small shops as it doesn’t take up much extra floor space. Bench-top models are also great space savers, particularly for anyone who won’t be doing a lot of routing, as they can be easily stored under a workbench. And, of course, bench-top models are portable. If shop floor space isn’t an issue and you want to maximize your routing potential, then choose a stationary router table.
 
If you have the time and skill set, and would like to save some money, building your own table is a reasonable option. Otherwise, consider buying a table – particularly if you are new to the craft. You’ll be up and running in no time. Regardless of whether you build or buy, the style of table you choose will depend on a variety of factors, including shop size, how much routing you’ll be doing, the type of routing you expect to be doing, and your budget.
 
As with any shop machine, you want to purchase a router table that will last for years, and provide consistently good performance. Here are some features to consider that will make your purchasing decision easier.

Three Main Types – Bench-top (top), stationary (middle) and mounted (bottom) are the three main types of router table. Bench-top router tables are nice when space is very tight, but are generally smaller and less robust. Stationary ones are quite popular, but take up more room. Mounted router tables, like this King Canada version, are generally attached to a table saw and are quite solid and durable. (Photos by manufacturers)
 
Flat, rigid table top
You want a top that is flat to begin with, doesn’t deflect once a router is mounted under the top, and remains rigid over time. Otherwise, you’ll find it difficult to obtain consistently precise and accurate results. In general, a heavier top is less prone to sagging and helps reduce vibration. Choices, from least to most rigid, include MDF (covered with plastic laminate), phenolic resin, and metal (aluminum, steel or cast iron).
 
Likewise, ensure that the base plate to which the router is attached is rigid and flat. The plate needs to rest perfectly level with the table top and not shift in use. Leveling screws embedded into the underside of the tabletop make it easy to adjust the base plate. Alternately, you can use a router lift instead of a base plate.
 
If you plan to use the same router for both hand-held and table-mounted routing, ensure that the process of installing and removing the router from the table and base plate is quick and easy. If you do opt for a stationary table, and you install a router lift, bite the bullet and purchase a second router that you can leave permanently attached to the table. It makes life a whole lot easier. Ensure the tabletop has an integrated mitre track. It will enable you to use a mitre gauge, mitre sled as well as some types of featherboards and accessories.

Split Fence – A split fence allows the opening near the bit to be adjusted. Benefits include safer routing, increased workpiece support during the cut and better dust extraction.
 
Fence square to the table
As on a table saw or jointer, the router table fence is indispensible. It has to be dead square to the top, quick and easy to adjust, and yet remain immobile when locked in place. A taller fence offers greater stock support for when pieces are machined on their edge. Because the fence is adjusted so frequently, it’s important that the fence locks are easy to adjust.
 
A fence that has two movable sub-fences, called a split fence, allows for better chip collection than a continuous fence. Split fences also help to reduce tear-out because they act like a zero clearance insert on a table saw, reducing the open space on either side of the bit. Also, supporting stock close to the router bit makes it safer when routing stock.
 
Some fences have T-slots integrated into the top or face of the fence. These enable you to mount various accessories, including hold-downs, stops, featherboards and micro adjusters.

A Strong Fence – One of the most important aspects of a good router table is a solid, square, easily adjusted fence. Look for comfortable handles that are easy to use and lock the fence in place well.

Easy to Access – Whether for simplicity, or safety, an easy-to-reach on/off switch is very nice to have.

Easy Changes – Whether or not bits can be changed from above the table’s surface isn’t a deal breaker, but it does make life easier. You may even find that removing a router from the table is the easiest way to go about changing bits, but it really differs between products.
 
Accessible power switch
You really don’t want to have to reach under the router table to access the power switch – especially if you need to turn off the power quickly. It’s much more convenient, and safe, to have a remote power switch located somewhere easily accessible. A large paddle-style switch mounted to the base can be easily reached or activated with your hand or knee pressure.
 
Quick and easy bit height adjustment
Probably the most frequent setup operation a woodworker will perform on the router table is raising and lowering a bit followed by changing router bits. If you mount the router on a base plate, you will have to reach underneath the tabletop to adjust the bit height, and you will have to lift the router and base plate out of the table to change bits. Some routers allow for above-table height adjustment, though you may still have to reach under the table to depress a spindle lock if the router has one, or to release the motor clamp. You may also find that the collet doesn’t fully extend above the top, making it awkward to remove the collet nut.
 
An alternative to a base plate is a router lift. It consists of a carriage to hold the router motor, a ratcheting mechanism to raise and lower the carriage, and a base plate. A removable crank handle, inserted into the base plate, enables you to make very precise height adjustments. It’s pretty much the ultimate in height adjustment and easy bit changing.

Table height adjustment and mobility
The ideal height of a router table is one that enables you to work comfortably and safely. A table with leveling feet will not only enable you to customize the height, but you’ll be able to adjust the top so that it is level and doesn’t rock. Casters are important if you will be constantly moving the table about the shop.

Have Casters, Will Travel – If you will need to move your router table around the shop regularly, casters will be your best friend. On this model the leveller feet enable the user to ensure the router table is level and doesn’t rock, no matter what location it is in.

Starting Pin – Some router tables, like this Craftex version, are equipped with a removable pin. If you’re using these router tables without a fence you can position the edge of the workpiece against the pin and rotate the workpiece into the spinning bit. This is safer than starting the cut completely freehand. (Photo by Busy Bee Tools)
 
The right router
Even though this list ends with routers, they are arguably the most important component of a router table system. The right router for your router table will depend, in large part, on the kind of work you do, and the style of router table you choose. If you will be working on small projects, almost exclusively with small router bits, or buying a bench-top table, then a midsize router (1-1/2 to 2-1/2 HP) would be sufficient. Otherwise, install a production router (3 HP or larger). It will run cooler than a mid-size router and have the power to run even the largest panel-raising bits.
 
A router table’s ease of use, versatility, and accuracy will transform your woodworking, and is sure to become one of the most useful machines in your shop.

How Big? – Midsized routers work well for smaller runs and bits that remove less material, but larger production routers are great for larger bits and heavy usage.
