I checkjed the mail and the bearings for those motors were in it, so I put a fresh set in the noisiest one, run on the vfd nice and quiet now.
I left the oven on broil while I "customized my puller" so it could get behind the load end bearing and pull it. About 4 hours had elapsed when my back said it was done and I turned it off, so it should be cool enough to saw by now. :) The first one I cut free from the edge of that bar warped open in the saw kerf by nearly 3/8" in a 10" long cut, and I was hours getting that hammered straight enough to use with a dead blow hammer. The bar has had 2 pieces sawed off it now, and the bar started out with a fat belly I had to trim about 80 thou off to get a straight edge again. The other edge is even worse, good 1/8" of fat belly from cutting off a previous piece. Silly Q: Going online to the metals pedlars, C360 seems to be what 90% of the bar stock offered is. But regardless of the alloy, its all stated as not being heat treatable. Since extruded brass is called half-hard, or HO2, it can be played with in the oven (if its hot enough), but always to soften. Are they simply trying to head off the idiot that thinks ferrous and wonders why his stock is dead soft after he heat treated it like steel?
