: I am building 1 threaded metal pipe framework for my daughters school project and I want to know the best way to measure the pipe accurately. For example if I want to make a 48 x 24 (exactly) rectangle of 1 steel pipe, do I have the pipe cut/threaded (minus the elbows and Tees) 2 short (46 and 22) to account for the ends? : Thanks youhow far you screw the pipe into each ell will need to be considered. remember you will need a left hand thread at one point.
