Introducing the Most Significant Improvement in Miter Guide Design in Over 100 Years...
The Osborne
EB-3 Miter Guide
The All New Osborne EB-3 was completely reengineered to incorporate improvements and suggestions received from our customers over the years. It brings together the ultimate engineering advantages of our patented triangular design.
The Latest Features Include...
• Three expansion slots in the guide bar, which provide a more positive fit in your saw. The adjustment is made from the top to easily & quickly establish the perfect fit.
• New fence extension allows for solid support of long material and carries the flip stop out to 42 inches.
• Fence adjustment from side to side to put blade clearance exactly where you want it.
• Accuracy within 1/30th degree right out of the box, but includes a simple and precise ZERO calibration adjustment feature should the need arise.
Adjusting and Reversing the Fence is simple! To adjust the fence closer to or farther from the blade, loosen the two fasteners on the rear of the fence.
Then position the fence exactly where you want it and tighten the knobs. To reverse the guide for use on the other side of the blade, simply remove the two fence fastening knobs (fig. 1) and the fence attachment plate (fig. 2), slide the index bar out of its track, then simply reattach the telescoping arm to the other end of the fence attachment plate (figs. 3 & 4) and replace the knobs.

In this semi-transparent illustration you can see how the connection between the riser and the red extrusion is off-center on the cylindrical riser.
A hex key can be inserted in the hole in the top of the red extrusion to loosen the connecting shoulder bolt. Then, by rotating the black riser, the entire extension arm assembly can be precisely adjusted as you see fit to plus or minus exact zero.
This is a detail of one of three expansion slots in the guide bar that allow you to precisely adjust the actual width of the steel guide bar to perfectly fit your saw's slot. The hex key provided fits in the center hole to turn a set screw which advances up in a tapered hole spreading the steel. This takes any lateral play out of the fit. The heavy gauge steel T-Slot washer is removable.
