... I was thinking of getting a tree stump and placing it in my
room on the floor ....
I too have a stump in an old (150+ yrs) wood-floored building and
have neighbours that I need to keep happy.
My approach thus far (2 yrs now) has been to put my stump on a short
stack of folded carpets and blankets when I’m pounding away on it. I
figure if I can’t feel vibrations through the floor then there won’t
be much sound travelling through there either so … I work
bare-footed! Not all the time, just when I’m working at the stump.
The bare-feet-on-the-wooden-floor thing really puts you in touch with
how much vibration is making it through the blankets. With 8 or
twelve layers of carpeting/blankets/etc not much gets through. I
really have to pound the hell out of something in order to feel even
a ripple in the floor boards. And so far no complaints.
Of course the blankies under the stump doesn’t do much for the
airborne sound but that’s magnitudes less likely to irritate someone
than the floor boards vibrating like I’m running a pile-driver in
here. When I’m working on my big anvil or stakes I wrap the base of
them in a folded blanket too. That really cuts down on the ringing
and is only a minor inconvenience.
FWIW I was able to buy a 4-pack of used packing blankets like movers
use for under $20. They ain’t pretty but they are nice and thick.
