I too was victim to Delta's poor quality in the manufacture of trunion. They seemed to just fall apart like plastic. Trying to order was was frustrating since no one had them in stook and didn't know whan they would get them.
Fortunately I was shopping for a replacement saw when I noticed that the trunion on the Jet band saw looked just like the ones on the Delta only better made. I ordered the Jet trunions and they woork very well.
