I did more fenceline clearing today, big difference between clearing to survey exact property line points (yesterday's work) and clearing room to actually put up a game fence. Made nice yellow clouds of cedar pollen, which for those of you not familiar is like airborne battery acid. I wore a good particle mask which helped a lot but the my eyes are half swollen shut.
The better news is I have a new fence-building weapon that may be of particular interest to Bret: A Bosch SDS max 4" carbide drill. It's like a core drill except it has carbide teeth and a spiral groove around the outside for clearing dust, and is intended for the hammer drill and is to be run DRY. With a small genset and SDS max hammer drill you can make holes in any kind of solid rock, anywhere you can drag the tools, which in my case is up a hill that a horse wouldn't take you. In half an hour I got down 12" in solid, crystalline limestone, stopping 4-5 times to break out the core with a chisel and pull out the chunks. Tomorrow I'll take my electric leaf blower up there to clear out the dust periodically because it binds up the works and slows down the cutting significantly when it builds up inside the cutting cylinder. Goal is 20" for the line posts but I can live with 18". Even a foot deep in solid rock is stronger than the 2-7/8" X 5/16"-wall pipe. I should be able to pre-fab posts with caps and pre-drilled tabs welded on so that I can haul them to position and bolt an X-brace between them, thus no on-site welding will be necessary.
