Has anyone else tried using dovetail router bits in their Shapeoko and found that the cutters did not seem to match their claimed dovetail angles? I’m not sure if I’m missing something about how to measure the angle on a dovetail or if the cutters are just junk.
I’ve got three (admittedly cheap from Amazon) dovetail cutters here, none of which match their spec when measured, I’m a little surprised as the other Yonico cutters I’ve purchased have been pretty good, it seems the only dimensions that match on the dovetail cutters are shank and the tip diameter, angle seems to be something they make up at the factory on that day.
Yep, if I’m cutting vertically with the matching bit for the tails then I’ll get the same angle, symmetry wins, but if I’m machining flat then I need to know the angle the bit is cut at to tell Fusion what shape tail to make. I’ve made a vertical clamp jig but I’m working my way up through flat cuts to vertical trying to get a clean version of each as I learn.
I was also considering using the dovetail bit more generally as an undercut to allow me to get an angled side on a workpiece.
I thought I was missing something in the spec or measurement as the bits just don’t seem to bear any relationship to the angle they claim, there seems little point in writing “10 degrees” on a bit that is just over 6 degrees.
