Motorcycle popularity has grown substantially in recent years, and many small shops that produce custom-made and limited-production motorcycles have sprung up. Two such shop owners, Brad Ruel of The Wrench and Mark Evans of Diablo Chop Shop, took it one step further and joined forces to combine their experience in designing and manufacturing semifinished (kit) motorcycles, completed bikes, and a substantial line of aftermarket parts.

Pointing, sometimes called tagging or swaging, is a process that reduces a tube's end to permit it to pass through a draw die for a drawing operation. After the tube end goes through the draw die, gripper jaws converge on the point to begin the draw operation. Push pointing is accomplished by gripping a tube and advancing pointing dies over the end, resulting in a reduced end diameter.

Verifying that tube was bent correctly is not as simple as it sounds. Bending specifications and tolerances aren't cut-and-dried, but are open to interpretation. The fabricator, the end user, and the check fixture designer might have three different perspectives on specifications and tolerances. Achieving a consensus is critical for designing and manufacturing a check fixture.
