and a sheet of flat steel to protect the floor.

We are having our oak hardwood floors sanded and refinished . I am having
the job professionally done, but there is some preparation that is my job.

Included in the preparation is being sure that any nails in the floor are
either removed or countersunk into the floor far enough that they will not
catch on the sander.


There are about 12 nails that have heads that are flat/round/about 6/16"
in
diamater. These were nailed into the floor by a previous owner in an
attempt
to silence squeaky floor boards. The heads are too large for normal nail
set
tools and in any case it seems that it would take an awful lot of force to
sink these wide heads into the floor(perhaps causing damage,etc). The
nails
are not accessible from below.

Any suggestions about how to (a) remove the nails and/or (b) countersink
the
nails would be appreciated. Is it feasible to drill through the top of the
nail from above thus seperating the head from the body of the nail?

Thanks in advance for your assistance,

Bob
