Here are a few ideas… I’ll update if anything else occurs to me.
Ryobi 18V cordless 3/8” drive impact wrench (I know this said 1/2 drive before, but I think I’d use a 3/8 more.)
LED work light, something like this or this or this
3/8″ breaker bar — at least 14-15″
1/2” breaker bar
1/2″ drive to 3/8 socket adapter (1/2” female to 3/8” male)
1/4″ drive torque wrench – either beam or click type are fine, nothing too fancy.
Wooden Thompson rubber band machinegun (ROKR Thompson Submachine Gun Toy 3D Wooden Puzzle LQB01)
Revell Saturn V model kit. There are a couple of versions. One is ridiculously expensive, the other is available at Hobby Lobby for under $30. That’s the one I want.
Ambient WS-2909 weather station (if someone hits the lottery)
