Yep, the closest closet.

Correct, for future futzing, sussing and hopefully expediting more such consternation

I have many spindles and cups just for this purpose so I can quickly resolve issues at home when I'm working on them and avoid undue delays.

I regularly go to the co-op for a few cheap spindles to use in test fitting and often find what I need in the pile at which point I'm done with that and can move on without waiting on the wrong thing or having to run around and lose focus.
