[Ferro List] Question on mortar mixer paddles

[steve garner]

     My father was a brick mason for over 40 years and I use to help him
some during the summer when out of school. Every few days after clean up on
the mixer was done he could have me to put in a bucket of gravel and a few
buckets of water and let it mix for about 20 or 30 minutes. You would also
tilt it in different positions while running. This would remove almost all
of the build up especially around the paddles and polish the inside making
it nice and smooth to where the cement did not cling to the mixer.

wire wheel does a fair job of cleaning out the threads, if you need to.
Vibrating the steel with a pneumatic hammer makes a lot of the left on stuff
fall off - a flat 1 in dia tool works better than most. Then a flat chisel
well lift and break the material much easier.
