I may have some answers...

1) Depends on what the piece is and how it's attached. If it's welded, hammer. If bolted, replace. These are the most likely items.

2) If a motor is hard to reach, you might consider redesigning before the end of build. That's a little late now, but keep it in mind. Your best bet is to have a removable shield.

3) Firefly effect. Somebody dropped that one weeks ago... Which reminds me, how full are the bowls of hardware at the end of the events this year? About like normal?
