Topic tags/keywords: tablesaw miter gauge incra v27 mule m21

A couple of years ago, I bought a Mule M21 Miter Gauge Fence ( ).

It was great when I attached it to the stock miter gauge that came with my Jet table saw, but when I bought my Incra V27, the Mule M21 was relegated to a shelf in the shop. The problem was that to the Incra V27 doesn’t have open-top slots to mount fixtures and jigs like other gauges, and the T-slot on the Mule M21 is too high for the mounting holes in the Incra. The manufacturer of the Mule M21 suggests drilling two holes in their miter fence, but that gives up one of the things I like about the M21 … adjustability.

The solution was to fabricate an adapter plate. I picked up a piece of 1/4” aluminum 9” long x 3” wide at a local machine shop. I drilled/tapped/counter-bored holes for flat-head machine screws that match the slots in the Incra and drilled a couple of 9/32” holes to accommodate the T-slot on the M21.

This only cost me a few dollars to build, and gave me a solid, adjustable mounting plate for my miter gauge fence.

I just got one of these and I also have the Inca V27 but instead of an aluminum plate I used 1/4” plywood scrap.

Gerry – you haven’t patented yet have you ? My V27 calls for this “invention” ASAP !

Well done Gerry, it looks like a factory manufactured piece.

I quit using the mule fence when I got my SawStop … no sense in tempting fate by getting metal too close to the blade. Now I use a sacrificial MDF fence on my miter gauge.
