On this job we are doing theres a lot of structural steel posts on the inside corners of walls. They are just getting drywall glued to them ive been underbending 90s and then bending it to a true 90 from the front so like two 30 degree bends with a kick my problem is is i dont know how to calculate that for shrinkage or even know how far to make my next bend. Is there a name for this bend and a calculation?if its a 45 bend i put in it could i just measure it like an offset and do 1.5x the distance i need but how would i calculate what i gain.
