My mill is a benchtop-style arrangement, rather than a Bridgeport-style knee mill. My 4th Axis is based on a large diameter rotary table, mounted on its side. I always put my 4th axis on the left, because if I put it on the right, it would foul the quill handle, if I used it. Separate quill feed is manual, and although I can't recall the last time I used that handle in conjunction with the 4th axis, it's always a possibility. That position means feeds along the work at -ve X, which is not intuitively convenient, but I live with it.
