BN725 Walker-Turner. Upper wheel is Aluminum cast and mine has a minor bend which makes enough wobble to throw the blade. The bandsaw worked perfectly before it was moved so it may have tilted and hit in the move. I may have learned a hard lesson that having someone move machinery without my overseeing was/is risky. The Rockwell 40-110 16" scroll saw lost top and bottom blade holding jaw parts in the same move. The move was 1/4 mile. Today on eBay I found the bottom jaw parts. A good day for me.
