Learned a lesson with our ultrasonic cleaner and the vapor de-greaser. When some metals are COMPLETELY clean they will bond together just by touching. Now drop them into a home made ATF/Acetone mix to prevent cohesion (bonding). I bought both tools from the salvage dock of a big micro chip maker for a dollar a pound but passed on a 16" Hardinge lathe so of course my steal on the cleaners is forgotten but still crying over the lathe.
