The Excalibur Osborne EB-3 is the original, patented, rock solid, dead accurate triangular mitre guide. The solid triangular configuration keeps the guide absolutely rigid, even at the outermost end of the fence. No movement in the fence means no movement in the work, which equals no gaps in the mitre joint. The guide will fit into any 19 x 9mm (3/4" x 3/8") mitre guide slot, the guide bar actually expands in three places to provide a perfect fit in the guide slot. The fence can be adjusted sideways to be tight to the blade, and can be extended up to 42" from the blade. A flip-over stop is provided. The index graduations are clear and easy to read, the scale being large enough to set at half or quarter degrees with confidence. There is an indexing detent plunger for setting the guide at common angles. The accuracy should be perfect out of the box, but a simple, locking calibration mechanism is provided if required. The whole fence can be set for left or right handed operation with no tools in a few seconds.
This mitre guide is so simple and its easy to set precise angles. Your work is not truly accurate until you have the Osborne EB-3 mitre guide.
