Quick project questions for a rookie
I like the numbered questions. makes it easy to answer.
1. My Porter Cable nailers have worked great and were affordable. My friend's Bostich were good, too. Check around for lightly used, and make sure nails are easily available.
2. I'd buy a 20 or 30 gallon upright on wheels. Semi portable until you get the garage built, then semi stationary when you have the place to install it. When i went shopping, I was hoping to find a good deal on a Bel-aire or IR, but ended up with an OILED, CAST IRON Husky (made by C-H) and have been happy with it.
3. PT lumber is only needed on the bottom plate or sill.
4. If you run a course or two of block, to keep the framing and siding up from the ground, you'll have much fewer problems in the future.
