The other day I decided I'd better start making myself a "to-do" list of things that I've left unfinished for various reasons. Like most builders, I've therefore now got myself a book to jot down all these little things that I do not want to forget.
Today I also took this one step further. I do not want to close up any surface (eg; rivet final wing skins on), and then realise I've got a "to-do" list action to finish that would have been easier done prior to closing up (eg; replace bolt on aileron actuator bellcrank).
To help myself in this respect I therefore made up some caution tags which I can hang in a conspicuous place as a reminder that I've still got something to finish off here. The photos below show what I mean.
My home made caution tags
Caution: don't forget to replace that short bolt
Caution: Don't forget to replace these bolts with longer ones
