To properly align the three pieces of a true Y, what initial action should be performed?

• A. Quarter and centre punch the pieces
• B. Weld them together
• C. Clamp and bolt
• D. Heat and bend

Answer: (A)

Getting three pieces to sit true relies on establishing precise reference marks first. Quartering provides accurate angular references by dividing the layout into equal sections, while centre punching creates a small, hard mark at the center that all pieces can share. With these marks, you can align the pieces so their centerlines and arms meet correctly, giving a consistent reference for where to clamp or bolt them (and later weld if needed). Without those marks, clamping alone can leave misalignment, and heating and bending would distort the shape, while welding too early would lock in any errors.
