Starting with a stack of 10 2x10's and a few walnut boards I already had milled.  I let them dry a bit more in my shop for a month before dimensioning. 

Started getting leg blanks ready by laminating three 1" boards, about 5" initial width.  

In the middle of the project, I realized I really hated my old DW734 so upgraded to the cutech and I'm REALLY happy with it.  The dust collection is top notch

Lots of planing later, and having ripped them to 4.5" width, I have pieces for the first half of the split top ready to laminate

This was already heavy as hell.  I would grow to hate moving these pieces around

While the top glues up, back to working on the legs.  

Random shop photo, the bench will go about where I am

Got the legs jointed and planed to final size.  About 3" thick and 4.5" wide

Gluing up the second half of the top

Started my mortising out sections for the stretchers.  I had to step it up to painters tape to keep track as two sides of each needed a mortise cut out.  My shoulder plane was great for sneaking up on the fit, but most was hogged out on the tablesaw

I truly dislike this jointer.  I clear clogs before each use, but inevitably by the second pass, it clogs again and EVERYTHING comes out the top and on to my floor.  Hate it, even with a dedicated dust collection hose on it

The top two pieces have been put through the planer.  That was fun.  These things are heavy as hell

Even with the nice new planer, I needed to sand for a long time to reduce mill marks.  I think I probably could have let them dry even more.  

Starting to dry fit the base.  The stretcher pieces hadn't been cut to length yet obviously

I had originally thought about doing through mortises, but ended up just doing traditional.  They are 1" x 3" and 2.25" deep

Here I'm starting to lay out the stretcher for the top support of the bench top.  I kinda cheated and instead of doing mortise and tenon, just took out a kind of rabbet.  Later on I strengthened with dowels sunk 4" in

Not a bad fit

Took out most with forstner bits before cleaning up with a chisel

All the parts of the base ready for assembly.  Not shown, I went ahead and drilled holes for the leg vise on all four legs for flexibility

Before assembly, I put elongated holes in the top stretcher to allow for the top to expand and contract

Here we go!

Recess for the top stretcher

Side stretcher

Glued these up completely before glueing the long stretchers to connect each half.  Also chamfered the feet

Base is assembled

Testing out the leg vise hole diameter

No screws, just 1/2" dowels sunk a few inches in to reinforce the glued joints

Starting to lay out the mortises in the underside of the top for the base to recess into

Again hogged most out with a forstner bit and followed behind with chisels

They sat about halfway in without any persuasion.  I call that good luck!

A little convincing with my deadblow mallet sat them down the rest of the way.  

Still just dry fit to the top, now I'm starting on the sliding deadman.  I cut a triangle piece of solid maple for the bottom to slide on.  I didn't want to mill another whole piece of walnut and it won't be glued on.  I plan to update it later (along with the leg vise) when I have more scrap ready

The vise I got from Lee Valley was green, but I like black with walnut, plus it'll match the casters

I had to take this half of the top off to route a channel for the deadman to slide in.  Used a homemade edge guide with an upspiral bit to cut it

The deadman in it's base form.  the V groove on the bottom and rabbet on the top

I took some of the bulk off the sides with my bandsaw then drilled alternating 3/4" holes every inch (two inches apart per side)

Moves pretty easily

Put a few coats of danish oil on to protect it at least a little and make it pretty

Getting ready for assembly, making sure the bolt slides easily for movement

My wife checking the structural integrity

Starting on the leg vise chop.  I'm going to eventually make this walnut like the rest of the base, but I had 1x8 poplar sitting on my lumber rack that was readily available.  It'll do for now.  3 pieces laminated together.  Here I'm cutting out the area where the bottom wedge will go

It works!!!

Like Jay Bates, used a dowel to restrict lateral movement.  Works great

Final shot, all ready for use
