Jigs
From IAP-Wiki
Jigs are used to hold a workpiece to ensure consistent alignment of the workpiece to a tool or to another workpiece. An example of the use of a jig is to enable the pen crafter to make repeatable cuts in a pen blank for inlays or segmentation.
Sleds
A good sled design has several design elements.
- A sled should keep your hands away from moving saw blades.
- A blade guard is necessary to keep you from coming into contact with the moving saw blade.
- It should hold the piece while being cut and after the cut.
- It should not allow the piece or the off-cut to be grabbed by the saw blade.
