How to machine on both sides of the material?

Hey everyone. I am trying to machine some handles. They require two sided machining. I managed to create one relief for front (cutting perfectly) and another for back (cutting perfectly). 

However, the problem is when I turn the material the holes don't match. Back side is a bit tilted so hole from the back does not match the hole on the front. 

How could I do reliefs such that their frontal part exactly matched their back side? 

My material is a square, so shouldn't be a problem with me turning it. and I have a square angle clamp, so it sits in the same spot.

  • Montgomery,

        When you are using index point when milling 2 sides are you drilling them with the router just before you cut the material? For example if I were to mill 2 sides I would be wasting a lot of material (just saying). On my router I would be using some material, I would clamp the stuff down (and never moving it until I'm done) drill the holes for indexing, glue some dowels in those holes (that is the scarrrrry part because I might get them a little off) the holes would have to be exactly like in the material I want to mill 2 sides and should be tight enough so there wouldn't be too much slop. My 2 sided material would have to be smooth on both sides should and parallel, with all 4 corners with in (I'd say .010" or lower (being wood it has it's own difficulty) clamping (here is the problem child) any clamping will make the material become a squirrel but you need it to not move at all. I would be clamping from the ends, or I'd be purchasing an indexer a good quality one not some cheap crap.

       I think I've covered this but if I left something out let me know.
