You're welcome David.
China is notorious for using recycled metals from around the world & I wonder how much QC they put into purification?
My IPhone5 was likely made in China & didn't last a month, like WT?
Lets see some pics of your crawl space!
I kinda wish that was what I started out with, just a crawl space, then I'd have lots yet to do.
I spend about a third the time today down there messing around than what I did 3yrs ago just to make it last as long as possible.... moderation.
