Hiajthomas!!!
I mostly build autos, and i would be lost without my pinvise!!! I use it for making holes for wires hoses etc....
All a pin vise is, is a sloid peice of metal with knurled ends.. on one end, there is a small chuch that accepts the drill bit... You just simply turn the pin vise between your fingers andthebitdoes the rest........
Hope i explained it well.....
