So a while back I built Jamie a really nice portable workbench with storage for assembly and finishing. Well, I have found myself using it a lot and I decided that it was time I had my own. I really needed a quick and cheap portable workbench. These easy portable workbench plans will show you how I made my workbench for about $75 and in about 30 mins. Also, since these plans only use 1/2 of the sheet of MDF you could build another with only 5 more 2x4s and four casters.
