I need to cut across some T&G floorboards so that I can lift them for access. Cutting along the tongue is easy with a circular, jig, or even tenon saw, but I'm having more problems with the cross cut.
Our floorboards are screwed into steel joists; this means the cut has to be diagonal over the joist, between two screws, so that each remaining half is still secured to the joist (crude diagram below). This means that eg jig saw won't work, since the joist is in the way. Circular saw won't work without seriously gouging the adjacent boards.
Is there a good way to do this?
