Have to move two supply hvac floor vents and moving a return from floor to new soffit above projector. Plan is to make some register boots out of MDF and line with linacoustic RC.
MDF seems to disintegrate a bit in the screw hole when I screw it to 2x6's for my stage curve, but the head of the screw holds the mdf well enough against the 2x6. If I screw MDF into MDF to make a rectangular boot, will it hold together?
Thanks in advance
