On my setup, the only drawback I have is that the camera Z position is fixed. So, the camera field of view (and the accuracy) depends on workpiece thickness.

Marcus Your solution sounds like the one I have here: http://blog.f1oat.org/2013/09/01/the-webcam-mounting-bracket-after-machining-work/ The initial vertical alignment of the camera is painful, but when it is done, it is a pleasure to set the zero on the workpiece so quickly. On my setup, the only drawback I have is that the camera Z position is fixed. So, the camera field of view (and the accuracy) depends on workpiece thickness. Frederic. Nice mount.

I haven't done it, so this is just a quick-and-dirty idea. Take a couple of inches of 3/4 aluminium rod, bore out the middle quite a lot bigger than the chimera and then put a flat on the outside. Drill a couple of countersunk holes all the way through for screws to mount it to the mill head. Also drill and tap two pairs of holes at 120 degrees to the flat spaced to suit the camera. once the holder is mounted on the mill insert the camera and some dense rubber foam. The foam should be on the mill-head side of the camera, and the set screws that I forgot earlier should be on the other side. You can now twiddle the 4 screws to align the camera, and the foam will keep the camera pushed against the screws. The foam avoids the problem of there being a mill head in just the place you would need to apply your hex key. Consider making the tube a little long, then you can fit a bung when the camera is not in use. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Shape the Mobile Experience: Free Subscription Software experts and developers: Be at the forefront of tech innovation.

What would be the disadvantage of mounting it permanently on the side of the head? That way it is always there, and you only need to calibrate its position relative to the spindle, once. You could use a work offset. The permanent mount can't allow for different Z distance. Putting it in the spindle allows the Z axis mechanism of your machine to make this adjustment and bring the workpiece into sharp focus. If your machine is a knee mill with the Z on the knee, or a machine where the whole head is your Z movement, what you suggest is fine. My machine has a manual knee adjustment and a quill on the spindle, so the fixed head camera would require moving the knee for camera focus. it would still work, but might not be as convenient. Jon So in a sense, I'm one up on the knee mills. My Z drive moves the whole maryann, something over a foot IIRC.

Having just ONE Z axis instead of two is definitely better. But, a Bridgeport is what it is, and is a lot more capable machine.
