Hello,
I want to build a lot of MOC's, but do not want to take existing ones apart.
Sometimes I use a part in a certain MOC where I could have used another one. When building another MOC, I might realise that I needed that certain part.
What do you do in that situation?
Do you take apart the first MOC to replace the part, taking the risk that you do not know how to put it back together?
Do you buy the part (PAB, BrickLink,...) and leave your first MOC be?
