I just bought a new Craftsman router and was wanting a router table to mount it in and decided to build my own.

Some of the features I wanted were

Adjustable fence
Dust Collection
Switch to control router and vacuum
Ease of access to router

Step 1: Design, Materials and Tools

I modeled my design in Solidworks so I had a set of plans to go off of. I designed the top and fence out of 3/4" plywood I had left over from another project and the legs are made out of 2x4 material.

The top dimensions came from the largest piece of plywood I had so you can change this to fit your needs.
The location of the mounting holes came from my router base and my change depending on your router.
Size of dust collection hole in fence can be changed to fit your system.

Materials

3/4" Plywood
~5ft of 2x4
Wood Glue
2 x Outlet Boxes
1 x Switch and Cover
1 x Outlet and Cover
~16" of House Wire
2 x Wire Nut
2 x Wire Staples
Electrical plug (I used one off an old battery backup)
Assortment of screws from 1-1/2" to 2-1/2" (Used what I had laying around)
3 x 10-32, 1" long Counter sink bolts for mounting router (Use suitable size for your router)
2 x 1/4", 2-1/2" long Carriage Bolts
2 x 1/4" washers
2 x 1/4" Wing Nuts

Tools

Tape Measure
Chop Saw
Table Saw
Drill
Drill/Drive Bits
Router
1/4 Router Bit
Nail Gun (Optional, used to nail glued pieces so as not to have to wait for them to dry)
Taper Jig for table saw
Sand Paper
Outlet Tester (Optional but Recommended)

Step 2: Top

Cut top to desired size, for me this was the size of a piece I had laying around
Layout holes for mounting router, I traced the removable plastic plate from my router base to locate my holes
Layout slots for movable fence from the drawing
Center punch all holes and ends of slots
Pilot drill all holes
Drill 3/16" holes for mounting router
Counter sink holes
Drill 1-1/2" hole for router spindle
Drill 1/4" holes for ends of slots
Set router edge guide to 6" and router slots with 1/4" Bit
Sand all edges

Step 3: Legs

Legs are designed to use a single 12" piece of 2x4 for each leg and then a 12" piece ripped down center for the cross bars.

Cut 5, 12" sections of 2x4 (I cut 6 just in case I messed one up)
Layout angled cut on 4 pieces
Set up taper jig to cut correct angle
Cut legs
Layout legs to glue them together, make sure that you have 2 sets that mirror each other to make up each side of the legs
Start screws in the larger side then apply glue to smaller piece, flush the top of the 2 and drive the screws in
Repeat step 6 for all 4 legs
Sand all edges
Rip one of the remaining 12" pieces of 2x4 down the center, these will be the cross bars
Sand all edges
Glue and screw together the 2 mirrored legs with a cross bar as shown in the pictures
Repeat step 9 for the other set of legs
Attach the 2 sets of legs to the top, 2" in from the top edge on all sides

Step 4: Fence

Cut an at least 7-1/8" wide piece of plywood to the same length as the top (In my case 22-1/2")
Rip a 3" and 4" section
Layout the cutout section on both the front and bottom pieces of the fence and the holes on the bottom piece
Cut sections out, I used a miter gauge and cut them on the table saw but a jig saw or hand saw would work
Center punch, pilot drill and 1/4" drill holes in bottom piece
Sand edges
Glue and screw the front to the bottom section with the 4" section vertical
Cutout pieces for dust collection from drawings
Test fit all pieces, trim if necessary, sand all edges
Glue angled side pieces and nail, otherwise clamp and wait to dry
Glue top making sure to get a good bead of glue on all contacting surfaces to create a good seal and nail into the angle pieces, otherwise clamp and wait to dry.
Center top extension, glue, clamp and wait to dry
Drill hole for dust collection hose (In my case 1-1/2")

Step 5: Electrical

I wanted my switch to sit vertical so I cut an angle piece (about 8 deg angle) to put between the box and the leg, if you don't mind the switch being tilted you can omit this step.

Pilot drill then use 3/8" drill to drill hole in top of one box
Mount switch box to front using included nails
Mount box with hole drilled in top to the back leg as shown in pictures using screws
Run wire from switch box to outlet box
Wire hot (Black) to brass screw, neutral (White) to silver screw and the ground to the green screw
Run outlet chord into switch box
Wire hot (Black) in to bottom of switch and hot out to the top, use jumper to wire ground in as seen in picture and wire neutrals (White) together
Screw outlet and switch into boxes and attach cover plates
(Optional but recommended) Use Outlet tester to make sure everything is wired correctly and you wont ruin any equipment plugged in or shock yourself when using it.

Step 6: Conclusion and Recomendation

Overall I liked the way it came out and it works good for my use, if you have any comments or sugestions please feel free to post them.

A few things I would add or change would be:

Add slots to front of fence to allow adjustable auxiliary fences to be used on different router bits
Add slot to front of table to allow a bolt to cut circles with
Miter gauge slot
