I am in the process of building an Upshur Opposed Twin engine. After four failed attempts to make a one piece crankshaft I think that it is time to go to a built up crankshaft. This is small. It has 5/16 dia shaft and 3/16 thick side plates. Every time I get half done and try to turn the second journal it catches and bends something. I have tried soldering a spacer bar between the first journal plates but that has not been too successful. I just ruined try number four so it is time to rethink. My question is on how to join the pieces. On larger crankshafts I have silver soldered the pieces together but I am afraid of warping on these small pieces. Others have used loctite with and without pins. My experience with locktite has not been great. Any advice on this from someone who has built this engine or something similar? I am planning on running the main shaft all the way through and cutting it out after everything is together.
Thank you: Gordon
