Has anyone measured the kerf on the laser cutter recently?
The holes I cut for the #6 screws in my clock fit snugly around the screw, just like I was expecting. However, I just found out that I had misread the tables, and programmed in 0.1285 diameter holes for screws which are 0.1380 in diameter. The “proper” close-fit hole diameter should have been 0.1440, or 0.0155in.
That’s about twice what some sources suggest the kerf for 3mm birch plywood should be (about 0.2mm/0.008in). And I was getting that in the cardstock about have the thickness as well, where the kerf should be half that again (0.08mm/0.003in).
I can’t find the calipers to make a test run.
