A homeowner in Denver corrected my brush angle and it saved my back
Last month I was doing a routine sweep and the homeowner, a retired mason, watched me work. He said my rod angle was fighting the flue curve and I was pushing soot instead of lifting it. I changed to a 15 degree offset on my brush and the difference was night and day. Took half the time on that job and my shoulder stopped aching after two days. Now I check the flue bend before I even unload the truck. Anyone else get tips from customers that actually beat what your mentor taught you?
Watched a buddy of mine fight the same thing on an old farmhouse flue last winter, and the homeowner there told him to stop choking up on the rod so much. He switched his grip and the brush finally followed the bend instead of scraping the sides. Funny how the folks who've lived with these chimneys for thirty years know the curves better than any class ever taught us.
