I found myself in need of a mid size marking gauge for milling rough lumber (by hand of course) so I mocked this up. It needs a better screw and knob as well as some overall refinement but I'll likely build a new one and still use this one.
It's cherry, mahogany and curly pear. The knife is O1 steel and needs a bit more camber before I harden the cutting edge. it's pretty hefty and can mark up to about 20" wide.
I should have taken pictures along the way but it was a little de-stress project and I was so in the zone I just busted it out in a couple hrs.
It has a captive block of cherry inside the gauge that applies pressure to the beam when the screw is tightened.
Thanks for looking.
