Great process details Papa!
The way those patterns are laid out really makes hitting your dimensions seem possible for us mere mortals 🤠

Your tape comments are spot on with what I experience. Gets worse if I have the taped parts clamped or in a vise for some reason.
I always use the same brand so I'll have some control over what it'll take to separate the parts. Use just enough and place the tape where I can get leverage to break the connection, either by prying or twisting.
