I assembled a project I was making with tight tightbond2 glue. a couple of days later i discovered that i assembled the part wrong, I tried every way i could think about to get it apart with out breaking it, I was then told by a friend to use vinegar,I didn't want to soak the part so I took a foam paint brush and dabbed the joints with vinegar a couple of times and when i wiggled the part at the joint it came apart now All I have to do is clean up the joints. just a little information for others that don't watch what they are doing, don't be like work smart.
