Feel free to move to another forum if this is in the wrong place. It seemed more of a software type of question as in what to use.
I've used structured light to scan some gun stocks that I've made by hand. I'm trying to reproduce them using a 3-axis cnc router. The scans themselves are perfect representations of the stocks but I'm having problems getting the planes of the model perfectly symmetrical before slicing/dividing the model in half for cutting. When cutting, one end of the stock is coming out thicker/the other end thinner than it should be. When flipping the piece of wood over to cut the other side this causes the two sides to not perfectly match up (and requires a lot of hand sanding). I was wondering how to go about getting it aligned perfectly in the x/y/z plane before slicing it in half so that the two sides are seamless and match the models measurements after cncing. I'm currently using Rhino/Rhinocam to try to align the scan correctly in the x/y/z axis before importing each half of the model into aspire 3 for 3d cnc programming.
Eventually I hope to go to a 4th axis rotary attachment so I don't have to deal with it. Any one have any ideas on how to get this perfect? As it stands now I have to trial and error the model until it's as close as I can get it
Pictures below. The unfinished stock is an older one before i did structured light scanning but shows the problem
