transfer pavilion to table should not involve your machine at all. The transfer and its alignment is 100% in your transfer fixture and its use. If you experience a shift the first question to ask, is the dop keyed or not. If dops keyed are both matching and machined the same if not keyed it is on your extra alignment methods before locking into the quill axis. One can and many do easily transfer a keyed dop with a stone to a round dop for table facets, it just takes more work and possibly tools to adjust the alignment after the transfer back to 100% alignment with the quill axis.
