Subject: flat-ground saw, taperground saw There are three ways that the sides of a saw are finished (ground) when manufactured. Each finish affects the thickness of the saw in a particular way. These finishes are: flat, straight taper, and crescent taper.A flat-ground saw has the same thickness everywhere. A taperground saw is thicker at the teeth than at the top edge of the saw. It is not as likely to bind in a cut, especially if the kerf is closing behind the saw as happens if the wood being cut is under compression. Another advantage is that a taperground saw requires less set than a flat-ground saw. The difference between a straight taper and a crescent taper is in the lines of equithickness for the two saws: straight lines as opposed to lines concentric to the circle of the saw. This means that the teeth of a saw ground with a crescent taper are the same thickness, while the teeth of a saw ground with a straight taper are thicker toward the center of the saw. Вопрос: Что есть finish и ground в данном контексте и как здесь правильно обозвать виды пил. |
| ground - заточены от grind |
| даже вернее отшлифованы |

Вообще-то зубья пилы разводят - "A poorly filed saw..." Этот Ваш текст отсюда - знающие люди посмотрят на картинки и скажут, что есть taper, а что ground. А finish - может быть "отделка" www.fhwa.dot.gov/ENVIRonment/fspubs/77712508/page01.htm |

| А ещё можно обозвать так "пила с плоским полотном" и "пила с полотном, утолщающимся книзу, к зубьям ", но профессионалы сразу приведут устоявшиеся названия. |
