Renovation of the main downspouts. primer coat top coat the big downspout, straight as an arrow. a more informative view of the big downspout. detail of the bracket cover. I enjoyed a day hanging downspouts with dad to wash away the conference fatigue. March 14, 2010: first rain storm of the Spring! The sluice worked like a charm. Note that it's overflowing. I need to repair the other barrel and figure out a solution for the overflow. Detail of the sluice. I set up the first barrel, went into the garage to find the hoses to hook up the second, and by the time I got back it was already half full: that's how fast it's coming down today.
