It all about how accurately you can place your piece after turning it and on your WCS zero. I think you have it at the bottom left corner of your stock and at milling table z depth. It looks like your stock is the same size of your piece, right?. You will only drill and mill holes, chamfer corners and mill a slot. I have stopped using tape. I don’t like the mess. I would use wedges to hold the piece in place with a corner milled into a wasteboard for registration. Like this:
Don’t pay attention to all the holes in the wasteboard. These were done as an experiment to using pegs for alignment. They worked but I dint’t like that the wasteboard material is too soft and would give with pressure. The idea is just to make a pocket that fits your part and some wedges to holt it. Holding material to the work table is unique to every part and project. It’s something that I’m still learning and experimenting with. If this piece you are making is just a one time deal, then maybe taping it might be a better solution for you. If you plan to make more than one, then maybe the slot and wedge would be more effective.
My table is all drilled with 10-32 holes at 1/2" spacings. Here is a link of another little experiment I did to test flipping using just the vise and careful zeroing and job setup. You can see my table there.
