For a motor mount (quadcopter) I need to drill holes more or less exactly in the center line of a carbon beam to avoid twist. However the beams are varying slightly in thickness as the are roll-wrapped. With hand tools I’d use a simple self centering doweling jig, but with the shapeoko3 I’m scratching my head
It might sound easy to you but:
How do find the centerline of such a beam with the shapeoko3?
Hmmm… might be easier to make a jig with the shapeoko and then use the hand tools to finish. Are you drilling the center of the ends of the rod, or center along the edges?
The beams are 15x15x360mm and wall thickness is approx 1mm. The holes and cutouts need to be on different faces of the beam. In CAD I’m using the centerline on the faces.
I’m using the end of the beam as y zero, but the x zero is tricky to get zeroed to the centerline.
In the mealtime I thought about attaching the jig to the endmill, set zero anywhere, clamp one side, move y, clamp again. However I thought there might be an easier way.
Hi Joel,
Thanks for your reply.
Do I get you right that you would “touch” both sides and take the center between the readings?
