Ko te tineia te mata paipa paipa paipa tika me te whakamaarama i te wera ka mahia ma te whakamahana whakawera, ma te mura ahi ranei.Ko nga tawhā hangarau matua ko te pakeke o te mata, te pakeke o te rohe me te hohonu o te paparanga pakari.Ka taea e te whakamatautau whakamaroke te whakamahi i te whakamatautau pakeke a Vickers, i te Rockwell, i te mata ranei, ka taea hoki te whakamahi i te whakamatautau pakeke Rockwell.Ina he matotoru te paparanga whakamaroke wera o te mata, ka taea hoki te whakamahi i te whakamatautau whakamaarama a Rockwell.

Mena ka hiahiatia kia nui te pakeke o nga waahanga, ka taea te whakamahi i te tiini whakauru me etahi atu tikanga mo te maimoatanga wera o te rohe.Ko taua paipa paiherea tuitui tika e tohuhia ana ki te waahi o te whakamaarama wera tinei i te rohe me te uara pakeke o te rohe ki te tuhi.Me whakahaere te whakamatautau pakeke o te paipa paipa paipa tika ki te waahi kua tohua.

Ko nga uara pakeke e toru o Vickers, Rockwell me Surface Rockwell ka ngawari te huri tetahi ki tetahi ka huri hei paerewa, tuhi, uara pakeke ranei e hiahiatia ana e nga kaiwhakamahi.
