No matter how cleverly engineered a table saw might be, it always seems like the miter gauge was an after-thought. The ones that come with new saws are typically barely usable, and most after-market miter gauges assume the miter slots in the tables are straight and uniform (spoiler alert: they're not). So, our engineers set out to develop a new type of miter gauge. A miter gauge that reliably performs the one job woodworkers need most from it, a perfectly square cut, and can do it regardless of how sloppy the machining of the miter slot.
