I wanted a barrel vise and wasn't too happy with the prices of the vises I was able to find online so I drew one up in Solidworks. Estimated material cost is less than $50 and a local machinist will mill the slots and v-ways for cheap so I will have a 10-times sturdier vise that will hold anything from .600" diameter to 1.250"+ diameter for less than the cost of one probably made in China...
