Book on tips and tricks for working alone
Good book; lotsa useful tips.
Good for if you're building things (fences, sheds, houses) by yourself -- tricks for if you don't have a helper available (e.g. to hold the end of the tape measure; holding the other end of the board).
WORKING ALONE: TIPS & TECHNIQUES FOR SOLO BUILDING, by John Carroll. (2001)
My copy says US$18. I see a few used ones on Amazon for about $12.
