Not for points Portuguese to English Art/Literary Idioms / Maxims / Sayings Possible regionalism

Source: transcription of a folk artist from Alagoas talking about his work. His language is colorful, poetic, and often obscure. I am attempting to separate his own idioletic usage from possible regionalisms.

There are no illustrations to indicate what the artist is doing/talking about. I have seen photographs of his work, all of which is carved from wood. Nothing indicates that he removes a chunk of wood and then glues something back in place, which is the image I get from his description here.

Might "emassar" be a mis-transcription?

"Aqui é um formãozinho pra olho, que a gente vamo gravando ele na madeira, e vamo virando ele assim, aí tá a formatura do olho. A gente tira, faz o olhozinho, EMASSA pra encaixar ele".
