The design for this mortise/cutting gauge was written up 10 years ago, but I have now made a few modifications, ones I have been planning for some time.
https://www.inthewoodshop.com/ShopMadeTools/Mortice-CuttingGauges.html
Dimensions: the fence is 110mm long and 50mm high. The arm is 170mm long. Built from Jarrah.
The gauge design incorporates a few features which I have not seen elsewhere.
The first is the round underside of the arm. The permits better siting of the cutter, as well as aiding with seating the arm ...
The profile of the fence is inspired by Japanese gauges by Kinshiro. The fence is an ergonomic grip, and pulled towards oneself.
The second is a cassette system for holding the cutters ...
I have a couple of mortise cutting gauges by Kinshiro. The cutters and construction is superb (he is considered the doyen of makers), however I dislike the separate cutters, as setting the them can be fiddly. Consequently, the cassette holds a selection of double cutters (made in M2 steel): 3/8", 1/4", 6mm, and 3mm (1/8") ...
6mm cutters in end grain (mmm ... that could do with some sharpening) ...
.. and the side of the rail ...
Why a 3mm (1/8")? Well, I often make drawers with slips, and these fit into a 3mm groove ...
At the other end of the arm is another blade holder ...
This is a cutting gauge for marking shoulders of tenons or dovetails. The cutter is M2 and ground to a curve, creating the same fine, clean lines as a wheel gauge ...
2-in-1.
