My workbench is quite old - at least 40 years. I got it from my uncle, who used to do some woodworking/carpentry in the past. Since I have this workbench, my woodworking became a lot more efficient and is giving me more fun, because I dont have to worry about good support for my workpiece.Its made of beech, the length is approx. 240 cm (95 inches) and its really heavy, the top is about 4 inches thick. It has two vices that are very comfortable. It also has two big drawers and on the back of the top there is place for tools. 
Despite its age, its still very stable and sturdy. Twice a year I clean the top with random orbit sander and put some oil on it.*******
Warren DownesHere is a nice little workbench i made for my Father in law, i used threaded rod to hold it together no glue or nails for the frame, the frame is unbelievably strong you can jump on it (i did) and there is no movement.
The top is 2 layers of 19mm MDF glued and screwed together, i have an overhang on one side to mount a vice on, and holes for bench dogs.
George FulfordI thought Id show you the workbench for my meager little shop. Its weather-proof and tough. It is made from heart pine beams, 2x6s and cinder blocks. The beams were from my old house that was torn down due to Hurricane Ivan. They were axe-hewn back in the 20s for an old barn, then salvaged for my old house, now theyre my workbench. I love recycling wood :) If only it hadnt rained today when I took these pics. Oh well.
