Old house and a few things are quite bent! In articular, a joist
along a corridor (about 15 feet long* has bowed up ward, making a hump
in the floor. Building up the other joists running along here would
throw the floor level out in terms of skirtings etc, so it would be
good to be able to take say (I haven't measured accurately) 20mm-ish
off this one to flatten the floor. I know that will weaken it and I
would sister it with another timber to bring the strength back. So
how could it be done? 20mm is too much to plane etc. I thought of
putting a circular saw on its side and running it along but that
doesn't look very feasible.
Any suggestions chaps?
