Well with a bench vise this morning can't shift at all have given up as don't want to damage, what is my next course of action, if I need to soak it? What would be best? Failing that is there any other course of action I can't take prior to returning? I probably have not cleaned this enough but I have only used the mod 4 or 5 times in last 5 years of ownership, although I always clean the break.
