Rule #10; "I can make that" translates to; "I'm to cheap to buy it new."
Yes, what you all said, but the most important one is the material they are made of.A parallel vice is cast, a post vice is forged. You can forge on a post vice all day long and it will take any pounding you want to deliver to it.
I can guarantee to smash a machinist vice by forging on it in less than 10 minutes. Not all bench vice are the same though. I rescued a Peter Wright bench vice from under a bench half sunken in the dirt, and mounted it on a tripod. Had to make some parts that had rusted away, and cleaned it for hours.The thing is 5' wide, all forged and the base is bolted together with 5/8 bolts all around. The sliding mechanism is designed to take all vertical forces from hammer blows, and when it does not match the strength of a post vice where all vertical forces go in the leg, it is 10 times stronger than any modern cast vice. The tripod is 5"x3"x1/4" and the base plate is 9/16". The counterweights are exercise weights to give it more stability. The way it is mounted i can drag it around and take it to the job within reason, since all up it is more than 100 kg
