I'm just SW of Lance Creek, WY in the easternmost part of the state. It's in the middle of a huge cattle ranch - mostly sagebrush. It was awfully hot and dry last summer. Temps into the 100's on somedays, very little rain.
I have a 8x12 shed made of OSB I've had since 2012. I had to cover the top with metal and I have to paint the sides every 3 or 4 years. And also, out here, it's a lot dryer than Virginia.
Well I'm in Lakeland, FL right now, visiting relatives, but back at my place in WY there are no trees except a few Junipers and Ponderosa Pines down in the draw. I'm also 45 miles from Douglas and 2 hours from the nearest HD or Menards so building stuff is a logistics nightmare. I heard...
I might consider using hardieboard with the price of OSB up to $30 for 7/16" 4x8. I can remember when it was $8 a sheet not too many years ago. I might even start scrounging for old pallets and try and de-nail them.
I built a pole barn last summer and bought 4" SPAX T20 deck screws from Menards. I wanted the T25's but they didn't have any so I ended up buying (3) boxes for a total of $60. I must've gone threw 5 or 6 packs of T20 bits because the second my drill would let loose of the bit, it would...
Especially when you drop it in grass. My DeWalt drill is getting old and it sometimes comes loose of the bit when backing out a screw. I have to keep making sure the bit's in there tight. Sucks when you're up on a ladder and realize you lost the bit.
Use the T25 bits and not the T20's. The T20's are terrible. If they round out the screw, they will ruin the bit and then be more likely to round out the next screw. That won't happen as much using the T25's.
