Is it worth replacing my stock miter gauge?

If your stock gauge has play in the slot or will not hold an angle, this is a clear step up. It adds positive stops, an adjustable bar fit and a vernier scale that stock gauges lack.

Does it fit my table saw?

The 22-inch bar is designed for standard 3/4-inch by 3/8-inch miter slots, and the fit adjustment takes up play. Check your saw's slot dimensions before buying.

Does it come with a fence?

No. The gauge ships as the miter bar and head; a fence and length stop are separate purchases.

How many positive stops does it have?

It has 11 positive stops, changed with a trigger-style lock.

What is the vernier scale for?

It lets you set angles between the positive stops to a finer degree than the detents alone allow.

What reviewers say

4.9 / 529 ratings

Owners rate it very highly, praising its accuracy, repeatable stops and the snug fit of the extended bar in the table slot. Complaints are few and mostly about the learning curve of the vernier scale and the lack of a fence.

What people mention

AccuracyPraisedOwners say cuts come out square and repeatable at the positive stops.
Bar fitPraisedThe adjustable fit mechanism is said to take the slop out of the table slot.
LockPraisedThe trigger lock is described as fast and secure when changing stops.
Vernier scaleMixedSome find the fine scale useful, others say it takes practice to read.
FenceCriticisedBuyers note there is no fence or length stop, so those are extra purchases.

About the COMPASS MG-36Pro Miter Gauge

The COMPASS MG-36 Pro is a miter gauge for table saws. It uses a positive index system of tapered grooves and a spherical locking pin to set angles without slop. Pressing the side buttons of the Smart Trigger Lock with two fingers releases the pin, so the gauge can pivot and index to common miter angles. It can also be set by hand to any other angle.

The 22-inch miter bar has four eccentric blocks. Rotating them removes lateral play so the bar slides smoothly along the whole T-slot. A vernier scale helps set the miter angle accurately, and the gauge adjusts in 0.02 degree (1/50th degree) steps.

The black anodized crosscutting fence is a CNC-milled 6061-T6 aluminum extrusion that extends to 36 inches. Loosening two knobs lets the whole fence slide. A precision scale runs along the top, and two T-slots on the fence face accept sub fences. The flip stop slides in a groove on top of the fence and locks anywhere along it. It flips up when not in use. Once locked, it makes micro adjustments in 0.001 inch (0.02 mm) increments, and all graduations are laser etched. For stock without faces square to the table, the Stop Pin lets you index on the bevel.
