Looking for ideas on some sort of locking hinge. Basically I'm building a table and it needs an arm rest built off the front side portion of the top. Was wondering if there is a hinge that unfolds and can lock in place according to how it's stationed on the table...?I hope that's not to vague in my explanation.Thanks,JoshMiller Dynasty 200Millermatic 211Instagram?.... find me @ WELD_MEDIC
