I have the socket and ratchet set out, this removal of fence hardware takes the 7/16th or 11mm size. I'll be using a hand saw (only six 2x4s to shorten), and the drill to pre-drill the holes for the fence hardware screws (the size of small bolts). I'll go into the back yard next door to take a look at how they spaced the fence brackets on the corner posts or if there was an extra piece needed.

It is now winter in North Texas. We had a week of fall weather and that's all we ever get. The benefit to my schedule now is that I won't be at work 20 miles away during the warmest parts of the day when yard work is pleasant. I'll lay out a tarp in the garage to put the wood preservative on the fence slats without worrying about wind or weather. Good thing I cleaned out the garage last year and have plenty of floor space to do this work. A friend left a plastic tarp with me that she was going to recycle or trash; I'll lay it out for this job and then decide to reuse or trash it later.
