Question about how we used to layout tube sheets vs. how it's done now
Back in 2003 we laid out a 60 inch tube sheet with a chalk line, dividers, and a soapstone stick, and it took two of us the better part of a shift. Now the shop just punches the holes on a CNC plasma table and the whole thing is done before lunch. Does anyone else miss the old way, or am I just being stubborn about it?

Something about the math too. When you laid it out by hand you had to think about the pitch, the margin, how the rows stagger, all of it living in your head the whole time. Now you punch a program and if the numbers are right the part is right, but the guy running the table might not know why those numbers are what they are. Had a kid ask me last year why the outer rows sit closer to the edge and I had to walk him through tube expansion and the ligament width. Good question, but it made me realize that know how is walking out the door with us.
