Methods for producing glass components and obtainted glass component, e.g. optical fiber preform. A method includes providing a cladding tube () with a longitudinal axis including a first and a second bore separated by a chamfered region (); inserting a spacer () into the first bore; inserting a rod () into the first bore (); moving the spacer () into the chamfered section (), causing the spacer () to rotate within the chamfered region (); and rotating the cladding tube () into a vertical orientation, whereby the spacer () is prevented from entering the second bore () and supports the rod (). Each portion of the chamfered region has a height perpendicular to the longitudinal axis greater than the height of the second bore. The spacer has a length parallel to the longitudinal axis greater than the height of the second bore but less the distance between the deepest point of the bottom of the chamfered region and an intersection of the top of the chamfered region and the first bore.
