Abstract
A method includes: bending a sheet about a mandrel such that the sheet is tubular, wherein the sheet includes a first longitudinal end portion and a second longitudinal end portion; engaging the first longitudinal end portion with the second longitudinal end portion; and passing the sheet between a first knurling wheel and a second knurling wheel such that the first knurling wheel applies a first knurling pattern to the sheet over the first longitudinal end portion and the second longitudinal end portion and the second knurling wheel applies a second knurling pattern to the sheet over the first longitudinal end portion and the second longitudinal end portion.

A method comprising:
- bending a sheet about a mandrel such that the sheet is tubular, wherein the sheet includes a first longitudinal end portion and a second longitudinal end portion;
- engaging the first longitudinal end portion with the second longitudinal end portion over the mandrel;
- pushing the sheet along the mandrel via a base portion to a first knurling wheel and a second knurling wheel, wherein the base portion is positioned immediately adjacent to the mandrel and moves along the mandrel;
- and
- passing the sheet between the first knurling wheel and the second knurling wheel such that the first knurling wheel applies a first knurling pattern to the sheet over the first longitudinal end portion and the second longitudinal end portion and the second knurling wheel applies a second knurling pattern to the sheet over the first longitudinal end portion and the second longitudinal end portion.
