diy 2x4 workbench
modern builds: s.02 Ep.10
If you're building things, chances are you either have a workbench or need a workbench. whenever I moved into my new shop last year I bought the cheap workbench from Harbor Freight for about $140. It was better than I expected, but just not heavy enough or deep enough. It worked well while I needed it, but it's time for an upgrade.
This bench is made completely out of 2x4's and I'll have a supplies list below. Of course you could just grab a bunch of eight-footers, but I used 8,10, and 12 foot boards to make the most efficient use of my materials to keep it under $100. I talked about it in the video, which you should watch if you're planning on building this, and that is the wood I used. It's call blue pine or beetle kill pine. Essentially, it's normal pine used for 2x4's, but it's been infected with a fungus that will kill the tree. It also happens to turn the wood into this awesome blueish grey streak pattern in the sapwood.
I meant to make it all flat pack...you've heard the story at the end of the video though.
20 @ 72" (For Top)
8 @ 30" (For Legs)
4 @ 24" (Short Stretchers)
2 @ 60" (Bottom Stretchers)
2 @ ~57" (Apron)
Before building the base, I ran all the 2x4's for it through the thickness planer. I made them all 1.25" thick to remobe the rounded edges and get them all the same size.
Making the lap joints is simple with either a table saw or circular saw. Just be sure that you keep track of where you're cutting thorughout the process. Don't get mixed up.
I glued and screwed the base together. I used my pocket hole drill bit to create a recess for the screw heads to sit into. That way I could come back with a 3/8" dowel to cover the screws.
Before I glued and screwed my 24" stretchers on, I clamped averything up to make sure it was going to go together square.
I glued my workbench top in three sections. This allowed me to take my time on each sections to make sure everything stayed as square as possible. Also, I was able to run the three sections through my thickness planer to remove the rounded edges before I clamped up the table top as a whole.
I talked about wood movement quite a bit in the video. Basically what I did to account for it was drill oversize holes in my apron so that as the wood expands/contracts the screws have room to move too.
I put on 4 coats of polycrylic as a finish. its fast and easy and should help keep wood glue from sticking to the top so much.
