Good catch. Yes, the vent holes are there -- you can't see them in the picture and I didn't include them on the layout sketch. They are mentioned in
another thread, which inspired me to show what we are working on.
Since we have DRO on our manual mill, but no NC capability, we make the vents as a series of three round holes overlapping each other to align with each of four motor vent slots -- twelve holes total. Easy to dial in because only three numbers are required after zeroing the DRO at the motor pilot. So it is actually less trouble to provide machining instructions for the vents than it would have been to add them to my sketch.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
