I had a shaft melt down a while back and finally got around to getting the new shaft installed. The problem is that the sheath of the new shaft is loose from the motor connection. I tried to install it anyway, but when the cut head moves from left to right, it pulls the sheath out. Sooooo.....should I contact CW and have them send me a new sheath or can I fix it with something like an epoxy? I'm not sure what they use to glue the components together.
