I needed to clean the chimney of a new/old house I just moved into. I looked online and found a couple videos of professional chimney sweeps using a chain flail to remove cresote and soot from a chimney so I came up with this design for my own chimney flail that uses weed eater line instead of chains.
Step 1: Materials list
1 ea. - 5/16" x 6' all thread
1 ea. - table leg mounting bracket,
2 ea. - 5/16" nuts,
1 ea. - fender washer,
weed eater line.
To make this simple chimney flail I bought a 6' length of 5/16" threaded rod at Home Depot for around $6.00. I found the table leg bracket at the Habitat for Humanity RESTORE and paid a quarter for it. The rest of the materials were on hand in my garage. I call it the cheap sweep.
