Finished up the workbench. Made with mostly free 2x4s, with some extra 2x6s purchased.
Half laps everywhere.
Two sjoberg vises because I just have too much money to spend.
Dog holes.
Flip down casters.
Adjustable leveling feet that I designed and 3D printed. You can kick them over with your toe to adjust and get rid whatever wobble appears in that particular spot.
It probably is overkill structurally, but I had some other thoughts around this.
For the face vise, I wanted some dog holes on the side of the bench so I can rest larger material on dogs and use the vise on the other end. The diagonal brace give me somewhat arbitrary positioning, increasing in height with length. I'll find out if this ends up being useful. So far I've only used the furthest and highest dog hole.
As for storage, I left the other side open just for that. Not sure exactly what that will look like yet. I'll probably add some combination of frequent tools on the vise side and drawers on the open side.
