I ended up cutting out the entire subfloor of a half bath but wasn't able to make the perimeter cuts near joists so the sides of the subfloor are "floating." I'd like to put in some 2x4 blocking to give the subfloor better support but it's difficult due to numerous pipes below the joists and tight/awkward space from inside the bathroom.
Could I double up two pieces of 2x4 that are a 1/4 inch shorter than the width of the space between the joists, glue and screw them together while attaching them to the adjacent joists sort of like a slide rule?
Also, for blocking in general, is there a good method for measuring so that the block will fit snugly but not have to be hammered so much that it shakes the whole house?
