Which method would likely be used for rough alignment of machinery?

The rim and face method is often employed for rough alignment of machinery because it provides a straightforward and effective way to assess the alignment of rotating equipment. This method involves measuring the distances between the rim of a pulley or coupling and a reference point on the base or frame. By doing this, a millwright can see if there is a misalignment, and while it may not provide the precision of more advanced methods, it offers a practical approach to get machinery in the general vicinity of alignment before finer adjustments are made.

Using this technique is particularly useful in environments where speed is crucial, and where a quick initial assessment can be followed by more precise techniques, if necessary, once rough alignment is achieved. This contrasts with other methods listed, such as laser alignment or cross-dialing, which are typically reserved for more precise adjustments once initial alignment is established.
