This will be dictated by automated mount head openings and the clamping apparatus or by the ability to hold and control the sample by hand. Following the rough grinding step, the sample(s) should be ready for rough polishing. Rough polishing further...

... area to be polished increases, it becomes more difficult to keep the surface flat and obtain a high-quality polish over the entire surface, especially if hand polishing is used. Mount thickness is important if samples are hand-polished, since mounts more than ¾ in high are difficult to hold flat...

... for analysis of microcracking, it is usually best to not mount the sample. If only hand polishing is available, it is best to bond the samples together so as not to impregnate the microcracks. If mounting is necessary due to large-scale damage and fiber fracture, such as arising from impact loading...
