Chris's Tips
Adjustable parallels are not generally used like the parallels you use in a vise.
Uses include:
- Measuring the width of a slot; adjust the parallel so it fills the slot, then measure the parallel
- Setting the angle on a sine plate or vise
- As an adjustable gage block
- For leveling or adjusting odd-shaped work pieces in a vise
Vise jaws are often too deep for the work. In general, you want the top of the work piece to extend above the top of the vise jaws. To fill the gap from the bottom of the work piece to the "ways" of the vise, you use parallels.
Parallels are strips of metal that have been carefully ground so that the top and bottom edges are parallel with very tight tolerances. They usually come in matched pairs. Place one parallel adjacent to each jaw in the vise and place the work piece so it rests on the parallels.
