[QUOTE="RadarJet, post: 357850, member: 8862"] Looks like some nice repair and welding work there. I arc welded a small shaft and pulley back together once, and by using the 12, 9, 3 and 6 tacks it stayed mostly in line too. Since most of the torque on a drive shaft is concentrated on the outer edge it looks like you got plenty of weld in the most stressed area. How did you keep the heat off of the splines and avoid getting them too brittle? Did you do any post weld heat treatment on the shaft? The ER308 wire should keep the weld from getting too brittle anyway. Congrats on a great repair. Catch any fish while you were out? [/QUOTE]
