Here are some plans and a video I made about how to make a small or large workbench with laminated lumber, using nothing but 2 x 6's.

Step 1: Cut List

The whole point was to make a workbench heavy and stable, so using nothing but 2 x 6's split I made the top, legs and rails all the same base material. Although I will probably use plywood for the shop vac shelf on the bottom. The top is 14 split 2 x 6's 23 inches long, all glued together. The legs are 2 split 2 x 6's laminated together that are 27 inches long. The rails are a single split 2 x 6, 4 at 17 7/8” and 4 at 16”.

Cut List:

14 @ 26" - table top
8 @ 27" - legs
4 @ 16" - rails
4 @ 17 7/8" - rails

Step 2: Cut Your Wood Up

Prepare the Wood

Split all the 2 x 6's. Then square them up on the table saw and plane them. You don't really need to square them up, but I did. You are going to need about 31', so three or four 2" x 6" x 12' boards will be necessary, depending on how picky you are with the boards. If you want to exclude knots, and other imperfections, be prepared to go through more wood. I wasn't so careful.

Cut the top pieces at least 23 inches, really you should allow for some room to square the top up. The final top dimensions are 21 1/2" x 22 1/2" Make sure they are pretty smooth and use lots of glue. Clamp it up with as many clamps as you have.

Step 3: Prepare the Legs & the Rails

Legs

Laminate the legs by cutting them to the height you want. A normal table top is 30 inches, a counter is 36 and if you want wheels think about how high you really want the end result. I cut the legs to 27 inches. The 2 ½” top, plus the 27” legs get me pretty close to 30”. The band saw is also pretty tall, so it is perfect for me, you may want to alter this for your purposes. Glue up the legs just like the top.

Rails

Cut the rails, 4 @ 17 7/8” and 4 @ 16”. I used a 1 inch tenon, so you must account for that. Cut the tenons on the table saw, or by hand. I went with about 5/8” wide and 1 ¾” tall tenons. You really do need to properly account for this measure.

note: If you wanted to butt glue the joint, use pocket screws, or regular screws just remove 2 inches from each rail measure.

Step 4: Cut the Mortises & Glue Up

Mortises

Cut all 16 mortises. A drill really helps to remove material quickly, then chop out the remaining material with a chisel. I set the mortises based on where I wanted a bottom shelf. But you can place them anywhere you need to. The mortises near the table top come up as far as possible.

Glue Up

Glue the joints together. Make sure you add plenty of glue to the tenon and the mortise. Clamp everything, and give it a good 8 hours or so to dry.

Step 5: Attach the Top

Countersink

With the base all glued up, turn it upside down and countersink your drill bit about a half an inch and use 2 - 3” screws all the way around the top. You don't want to attach the top to the base too tight. There will be a fair amount of contraction over time as the wood dries. 2 x 6 lumber tends to be wet. If this is a concern you could use 2 x 12 lumber and select the best parts of it.

Finishing

You don't really need to finish the table. I did add a few coats of linseed oil. You could always stain it, paint it, or coat is in a varnish. It is all up to you.

Note: The basic construction of this table is perfect for a kitchen island, a baking table or even a larger workbench. Just extend the dimensions and it would make a great base for just about anything.

Step 6: Conclusion & See the Video for More Info

This is a very inexpensive build. Because you can just use framing lumber you can really make your money go far. All in all this should not take more than a weekend, and if you use easier joinery it will be even quicker. For a more in depth look, please take a look at the video. Thanks!
