We’ve found that even on high-end saws, the miter gauge is sometimes not the best it could be – a situation easily resolved by the folks at Kreg. You probably know them for their ingenious pocket hole system, but this miter gauge is worthy of fame in its own right. It’s not like any we’ve seen before, with a handful of features that work together to give you the ability to set an angle cut accurately to 1/10th of a degree – and beyond that, to adjust to 1/100th of a degree (hats off to you if you’re that precise!)
Setup takes a little bit of time and patience, but the results are well worth it. It’s got a super accurate length scale with a magnifying lens cursor, similar to those on good table saws, and the curved flip stop can be used with the fence as is, or you and a pair of pliers can modify it easily for permanent use with a sacrificial fence. This clever curved design lets you slide your stock right under it. The slot bar has five patented nylon screws along its length that let you custom fit it to your table saw slot, completely eliminating any play.
It’s got the positive stops you expect, at 0, 22.5, 30 and 45 degrees, and they’re marked by preset holes that accept a tapered brass pin, which locks in the angle with absolute precision. The gauge is marked with diamonds every five degrees for great legibility, too. But what sets this gauge apart from the pack is its Vernier scale, allowing you to set any angle in tenth-of-a-degree increments. Unless you have a degree in mathematics, don’t try to understand the process – it’s confusing and non-intuitive. Instead, just follow the step-by-step directions, and you’ll get absolute accuracy every time.
And when Kreg calls something a "micro-adjustment" mechanism, they really mean micro. With this miter gauge, you can actually increase your angle by 1/100th of a degree by turning a nylon screw that increases the space between the fence and the gauge. For each .001 inch you put between the fence and gauge, you increase your angle by 1/100th of a degree.
Kreg’s really hit the accuracy bullseye with this miter gauge, and adding it to even a so-so saw will give you fantastic results. Take your time with setup and follow the directions for the Vernier scale, and you’ll be as taken with it as we are. -- Kris Jensen-Van Heste.../ Kreg KMS7102 Table Saw Precision Miter Gauge System / bandsaw guide
