New to the forum here, lots of good information that I've seen posted. I was wondering if you all could be of assistance. I'm looking to join two pieces of round bar say about 3/4" end to end. If possible I'd like them to be able to fold up so that they are parallel on top of each other. I'd also like to be able to lock them end to end but I think I have that figured out. Just need the hinge part. Thanks in advance!!
