Need help with building a workbench top with glued 4x4s


I'm building a bench top made with Douglas Fir S4S 4x4s and want to make sure my plans/techniques checks out before I start. The dimensions are 28" x 58". I'm planning to simply glue them together with Gorilla Glue, then clamp together overnight to dry. Is this all there is to it to make a strong bond and quality top or should I be thinking about doing it another way?

Thanks.

Dowels or biscuits in there to better secure. I would use something other than Gorilla glue. As for clamping, overnight is not going to be enough, depending on temp and humidity of the space that you are putting it together for gluing. I would probably give it at least three days min, maybe a week max before taking off the clamps and Planing & sanding down to a proper thickness.

Thanks for the heads up about letting it dry longer and the dowels. I think I'm going to use Titebond III instead of gorilla glue.

Any decent good wood glue will work.

Very good idea. Gorilla glue pretty well...... oh well, it's just my opinion.

I never would have used 4 X 4's ever!
There not dimensionally stable enough, there going to twist and check.
Look at any hard wood work table, there a max of 2 X 4.
There also through bolted with threaded rod.

you could use 2x4 fir on edge, still giving you 4" of top. drill 1/2" holes thru
each 2x on ends and middle (use jig for uniform placement of holes) slide
each 2x onto 1/2" dowels.The dowels will keep things in alignment. Do a dry fit first, then i would use titebond III. You can add 2x's as long as you have
dowels exposed or add as many as your clamps allow, then continue.

This sounds like a plan. What do you suggest for making my jig? I'm thinking about using a piece of mdf cut to match the 2x4s after I rip to remove the rolled edges. Do you have a better suggestion? Thx

regular wood glue such as titebone 2 or 3 will work, so will lepages or elmers.

simply using a biscuit jointer will work fine. before you start using the biscuit joiner though you should run the lumber across a jointer on one edge and face then through a thickness planer to flatten it from there you can begin the glue up process

when your all set to clamp run multiple bar clamps along the length of it, then using 2x4's on edge both on top and bottom clamp these so to keep the bench top from curling up as you apply pressure from the bar clamps.

ive used this method many times, for buildng solid wood dining room tables, benches, and wood doors

There is no fixture needed, just set up the 2 X 4's on edge and clamp. Use a framing square to lay out the lines, reliece the clamps and transfure the lines with a speed sq. Drill the holes 5/8", they need to be through holes not tap fit so it will pull tight. If you use a bullet tipped type drill bit it will not slip around. Use can use a combination square to mark center or make a simple jig by marking three places evenly spaced on a piece of 1 X about 3" apart. The center hole gets drilled 5/8, the two outside ones get 1/4 holes, Drive in two 1/4" fluted dowels. Now you can just set the piece on any 2 X 4 and twist it and it will find center.

You can also swap theaded rod for the dowels, use washers and nuts on each end. they would act as clamps.
