I have this impeller all modeled up, but I still need to add a variable radius fillet to the base of each vane. The fillet starts as a .19" rad at the base of the OD, and at the top of the vane transitions smoothly into a .125" rad, then back down the vane's opposite side to .190" again. However, using the loft data that was provided by the customer, the surfaces between the blade and the hub are too far apart to knit, and I have had zero luck extending the blade surfaces. HELP!!!!!!! I have to program these parts for our 5 axis mill and I can't do that without a good model...................
