Scott, The siding is James Hardie Sierra 8 vertical siding, similar to T1-11 that is on the main house. We will be using 4 x 10 sheets. This is fairly easy siding to work with - it cuts easy with an angle grinder and a diamond blade and I have two or three of these. This siding gets face nailed with 2" galv box nails. We can use a gun to install this but it takes a special gun for these nails and it has to have an exact depth adjustment as the head of the nails must not be below the siding surface. I think hand nailing will be the best way to install this given there will be less than 25 sheets to install. The only hard part about installing this siding is that it weighs 90+ lbs per sheet. That is why I invited all you young guys over.
The highest point at the gable peak will be about 20 feet and the eaves will range from 8 to 16. I have a far amount of ladders, but an extra 16' or 20' extension might be handy.
Electrical work will consist of running flex conduit through the walls between the 4x4 wall boxes and home runs back to the panel. The 3/4 flex requires a 1 1/8 hole so I will pick up a couple of good self-feed bits and I have a Milwaukee angle drive drill.
Still trying to figure out what I am going to get for lunch, sandwiches just is not going to make it for friends willing to help on a Saturday. My wife is a gourmet cook. While she can no longer cook, Joan will come up with a great lunch
Thanks and hope for good weather
