Dè a th’ ann am pìob gun fhàinne stàilinn gun staoin
'S e stuth stàilinn fhada le earrann falamh agus gun chlaonadh timcheall air a th' ann am pìob gun fhàinne stàilinn gun smal. Mar as tiugh balla an toraidh, 's ann as eaconomach agus as practaigeach a bhios e. Mar as taine balla, 's ann as àirde cosgais a' ghiullachd gu mòr.
Tha pròiseas an toraidh seo a’ dearbhadh a choileanadh cuibhrichte. San fharsaingeachd, tha mionaideachd ìosal aig pìoban stàilinn gun fhàinne: tighead balla neo-chothromach, soilleireachd ìosal air uachdar a-staigh agus a-muigh na pìoba, cosgais àrd airson meudachadh, agus spotan dubha is claisean air na h-uachdaran a-staigh agus a-muigh a tha duilich a thoirt air falbh; feumar a lorg agus a chumadh a phròiseasadh far-loidhne. Mar sin, tha e a’ nochdadh a shàr-mhathas a thaobh cuideam àrd, neart àrd, agus stuthan structarail meacanaigeach.
