I'm thinking about mounting a thumb to my mini ex. It already has aux hydraulics on the boom for a breaker. I'm wondering the plumbing issues I'll have if I want to use this circuit for the thumb. Do I need a bypass valve that is less than the bucket psi? What keeps the two circuits from damaging either the thumb or the bucket when both are "competing" against each other when the thumb grabs onto something? The last thing I want to do is break something! Yikes! I just want to make sure I do it right and it's something new to me... Forgive a rookie question.
