Kerfmaker for up to 7/8" dado.

thingiverse

This is based off ccrumpacker's Kerfmaker, but I've remodeled it to be able to accommodate a full kerf from a 7/8" dado stack. I also made a few tweaks to tolerances of the sliding components along with improving the knurling and accessibility of the two knobs. Maximum allowable stock is right around 3". Simple half-lap setup: https://stusshed.com/tag/km-1/ Video tutorial: https://www.youtube.com/watch?v=PQ6_S6lZKLI Remodeling was done from scratch in solidworks and I've included the assembly/part files as well as the .STL files for printing. ***Model units are in inches*** make sure your .stl units are set correctly otherwise the imported parts will be very small. Print quantities: 2 - knob.STL 1 - top.STL 1 - middle.STL 1 - bottom.STL Additional hardware required (note I used McMaster for ease of modeling, but you can find this metric hardware at a local hardware store) Also, yes, the hardware is metric but the print is standard. It's the world we live in: 2 - M5 bolts, 20mm long https://www.mcmaster.com/#91310a124/=1afvdvs 2 - M5 nuts https://www.mcmaster.com/#98676a300/=1afvg2x
