Appreciation post: my granddad's old brush on a rope vs the rotary kit I run now
He swept flues in Fall River with nothing but that brush and a weighted ball back in the 80s, and last Tuesday I finished a two flue job in 40 minutes with the rotary setup. Feels like cheating some days, does anyone still keep a rope and brush in the truck just in case?
I still keep a rope and brush behind the seat for the odd chimney that has a bad bend or heavy creosote where the rotary just bounces off. What works for me is running the rotary first to knock the main stuff loose, then sending the old brush down by hand to feel what the walls are actually doing. It's slower on those jobs, but I've caught cracks and loose mortar that the rotary would've blown right past.
