3 in 1 Marking Gauge

This is my version of the 3 in 1 marking gauge from Shopnotes #130.

The lighter wood is a broad leaf maple offcut from an old butcher block that needed to fit through the planer. The knobs and fence are from a Kauri tree from NZ that was in a swamp for 45,000 years, incredible wood and the pics don’t do it justice at all.

The gauge is based around my shop made t-track (you can see my review of the veritas router bit I used here: http://lumberjocks.com/reviews/3935 ) the fence and other accessories ride on the t-track and lock down using shop made knobs that were drilled out with a hole saw on the drill press and smoothed on the drill press lathe.

The gauge can function as a panel marking gauge (pics 1 and 2), a story stick (pics 4 and 5) and a compass (pic 6) and can mount a pencil or blade at the marking head (pic 3).

The story stick markers have v-notches filed in the edge to guide a pencil or blade.

I made some improvements over the original design. In the Shopnotes version the pencil was held about 5/8ths under the body of the marking head, I don’t know about you but I like to see my pencil when I am drawing a line so instead of the wood clamp block I used a strip of brass left over from my spokeshave build (pic 3). Secondly the compass pivot plate called for 1/4 hardboard instead I took a square piece of clear acrylic and scribed lines right across to find center before cutting the circle with my router, now I can line up the center mark on the workpiece with the lines on the pivot plate rather than having to eyeball it through a 1/4” hole.

Here it is drawing an arc (kinda hard to see I know)

Liking this one a lot, if looked after it will outlast me I’m sure.

Thanks for looking.

Very nice jig! Gonna have to make one. I love the plexiglass, use it on lots of jigs! No warping or expansion/contraction with humidity changes. Makes really good runners for table saw jigs too!

I would love to make one but in my “shared Shop” someone would ruin it in a split second.
