What is the most used jig in your shop?
Its a simple question, but jigs are simple devices, often disguised under scrap material and hastily built parts. Still some of the heaps help us out everyday. They also do something else...they act as safety devices in disguise.
So which one do you use the most? Your tablesaw cross cut jig? Your circle maker on your bandsaw? Your jig that turns your planer into a jointer?
Mine is probly so simple, so overlooked, so stupid that you would not believe me. Its a stack of angles made out of OSB wood and Strapping. I use them mostly on my Radial Arm Saw, placing them up against the fence so I don't have to move the settings on my saw to saw say 45 degree miters, or 30 degree cuts, etc...which might throw off the accuracy of the saw if moved enough. They also save me a lot of set-up time.
So what is your most often used jig or fixture?
