My mill is an old Van Norman model 12 universal which has no quill, so any drilling needs to be done by manually cranking the knee which is a bit of a pain (only power feed is X-axis).
There were a couple of attachments for the VN12 that gave limited quill functionality, but unfortunately I don't have them.
I might end up making something similar - mainly for light accurate drilling operations (up to around 12mm diam) where there are a few holes required as I've got a reasonable drill press for general drilling.

I'm guessing on the larger universal mills the Z-axis power feed could be used, particularly if it has rapid feed to drop the knee back down when the hole is finished.

Just wondering if there are any other suggestions from fellow quill deficient owners?
