Hi, I am winding the springs for my 1/4 Galloway from music wire. I read some place that after winding they should be tempered by placing them in an oven at 450 degrees for 3 or 4 hours. Has any one else used this method? My big question is, if the springs need to be tempered, should they be quickly quenched after the heating period is over, or should they be left to cool slowly at room temperature? This may not be a big deal one way or the other, but I would like to get it right the first time. Thanks, John.
