I have been running this mismatched spline setup for over a year now. I have made several propeller shafts by taking a 2017 420 FA6 and a 2013 420 FM shaft, cutting them in half and welding them together. Eventually they break, whether it be at the weld or somewhere on the shaft. Does anyone know of a Machine shop that can or has produced a forged, not welded, propeller shaft with the correct spline sizes I need.

I guess this topic isn't as interesting as spark plugs or how to change my oil. Among all the Honda folk, jerry riggers, or oem gurus. not one soul has a potential solution or info related to a business stumbled upon at some point in life that has the ability to do this type of work. Interesting...
