Yea I never used or heard of smurf tubing either before this place! I used a ton of it all over my basement build. I used the carlon mounting blocks to attach my tube runs to. You can see in my build thread if care to take a look.
Your coming along very nicely. And your moving quick. Mine is taking me forever!
Dude, I wish I could do this kind of stuff myself. I just bought a house and I'm in Nebraska too. I bought a home built in 92 but the people were the same. Older and cheap. Well built home, but really dated.
