This is a simple little collapsible workbench/assembly table I made. The dimensions may seem strange but it was as large as I could get it while still fitting under my current one. It also is tall enough so that the surface of the mitre saw when it is up there is level with my big workbench, allowing my to easing cut long boards. This can easily be adapted to be a sturdy, permanent workbench with only a few extra bolts.
22" Wide, 35" long, 33 1/2" Tall
Step 1: Materials
You will need:
1-2'x4' Sheet of 3/4" MDF
1-Box of 2" or 2 1/2" Wood Screws
Material for the Apron (the part right below the surface)-the dimensions don't really matter, but I ripped a 1x10 in half because that's what I had on hand. You could use 1x4s as a cheap alternative.
Total Cost Not Counting Apron or Wood Glue:
Step 2: Legs
The legs consist of two 32" segments of 2x4s screwed and glued together. You will need eight individual segments in all. Use the first one you cut and base the rest off of that-you get more of the same sized legs that way. I ripped the edges off because it gives it a slightly cleaner look and makes them square, but if you don't have a table saw this is not necessary. You should have one 32" segment and a full 2x4 left over.
Step 3: The Stretchers
You will need two 22 1/2" boards and one 35 1/2". Square the edges if you can.
Step 4: Apron
I made these 4" wide, but that can change easily based upon your materials. These will need to be cut to the size of your tabletop-in my case 35" and 22"-with a 45* cut on the ends. The second photo is just a test fit. Then they will need to be screwed and glued into a square. A corner clamp really is helpful, I got mine for a $1.50 and an antique tools store!
Step 5: Table Top
Cut the top out of the MDF. I used the jig saw to cut the wide part and the table saw to cut the remainder.
