шатл, Здравствуйте. Заказала в инет магазине оверлок MO-654DE , а привезли MO-600 Series. Я отказалась, потому что про такой даже не читала нигде. Что это за оверлок, можете рассказать и стоит ли его брать вместо 654. У меня «чуйка» сработала, что мне он не нужен. Вы что скажите? Что за зверь? Спасибо.

О! Мне тоже в прошлый вторник привезли этот оверлок и крупная надпись на коробке MO-600 Series меня тоже смутила, но внизу была маленькая белая наклейка MO-654DE/CE3. Очень довольна. Сшила уже несколько вещей. Тоже долго читала тему и в дополнение Мэррилоку 11 (ну очень надоело перенастраивать, да и оверлочная строчка перестала устраивать в полной мере. Может, игольный блок пора менять) взяла Жука. Спасибо всем, и, в частности, Вам, Шатл.

Добрый день. Дозрела уже до заказа нового оверлока (бразер 1034) и вижу в магазине Джаноме 714 ненамного дороже. И хоть я джаномовские оверлоки сразу исключила, а тут на фоне такой цены думаю-а может зря.
Как 1034 и 714 в сравнении по работе на тонких материалах?
И еще-у бразера дифференциал 0,7-2,0, а у джаноме 0,5-2,25-на практике это большая разница в швах будет?
И еще вопрос-к модели 4234 идет сменный палец ширины строчки. Можно ли его к 1034 приделать и вообще-нужная это вещь?

Fraxine Дубовей конечно,но 714 из Джаноме ,это не плохой вариант,в принципе можно приспособиться и к тонким тканям и трикотажу, а так все функции и удобства.На 1034 тоже есть этот палец или стежковый язычок,он убирается для закрутки рулика,но конструктивно они разные и не взаимозаменяемые.

Добрый день! Планирую приобрести оверлок. Почитав форум, определилась с моделью — Juki 654 DE.
Шатл, очень нужен Ваш совет!
Сделала запрос в ИМ, но пришел вот такой ответ:
Нарекания на Juki 654 DE идут волной. У кого ломается верхний петлитель,у кого треснуло «плечо»(деталь для верхнего петлителедержателя),а кто жалуется именно на DE -электронную,типа,педаль.Плато в педали не функционирует.
Альтернатива: Janome 60789 -с обычными натяжителями
Janome 60788 -с вертикальными натяжителями
Janome T-72 с японскими петлителями и толкателями
Например на оверлоке Janome 60788 работнику,при шитье,очень удобно,благодаря специальным «окошечкам» видеть и устанавливать нужный ему размер дифференциала и ширину строчки и т. д.
Также эти оверлоки выполняют знаменитый ролевый шов(он очень тонкий и красивый—только у Janome и Elna).
Ещё варианты: Elna 664, Elna 664 PRO
Помогите! Планирую шить для дома, друзей. Бюджет до 13 т.руб.

Озвучьте пожалуйста название магазина, страна должна знать своих героев и ничего у них не покупать из-за их вранья.. (хотя я примерно догадываюсь кто это)

lenNM13 Это необъективная информация,никакой волны нет,петлители ,что верхние,что нижние ломаются на всех оверах и коверах,причем нельзя сказать на каких больше,насчет рычага привода петлителя,на Бразере и Джаноме такое встречал,на Джуки пока нет причем учитываю временную и количественную статистику нашего СЦ по Джуки,а это более 10 лет.Насчет педали,сразу не вспомню,не скажу,но в последнее время проблем с педалями не было,и имейте ввиду,что не обязательно,в случае поломки покупать фирменную педаль,к Джуки подходят педали,а они не дорогие,от некоторых моделей ШМ Ягуар.Про удобства и окошечки не скажу,это уже вам решать,это индивидуально,но никаких преимуществ Джаноме и Елна перед Джуки я не вижу,про закрутку рулика,тут даже писать не буду,здесь объективно лидеры Бернина и Джуки,а Джаноме,ну даже не на втором и третьем местах,здесь они не соперники.Насчет петлителей,видел я японские петлители от пром.оверов,поверьте Джаномовские,да и другие бытовые петлители и рядом не стоят,да и абсурд это,для других Джаноме петлители тайваньские,а для дешевого и простого Т72,их делают в Японии,смысл.

Ох, горе-горькое 
Металась-металась между 1034й и 654 (разница в цене 3200), все из-за шва двухниточного да ножей, ну и иголки у 654 крепятся отдельно. Прочитала тему заново и все же решила купить 1034. Думаю на пару лет ножей хватит (думаю от кулирок да интерлоков они не сильно затупятся).
Просмотрела в доме все вещи с руликами-на детских вообще двухнитки нет, на одном платке шифоновом есть такой, а другой тонкий платок вообще на ШМ подогнут на 1 мм вместо оверложки.
Думаю если делать рулик иламентными нитками, то и трехнитка будет не толстая.
Ну а по креплению иголок-буду развивать ловкость рук .
Ну в общем это себяя уговариваю, что 1034 не хуже 654.
И еще вопрос (а то в теме бразеров мне никто не ответил)-на обчных швах можно поставить длину стежка 1-1,5 мм? В инструкции написано, что мин. длина 2 мм, а при ролевом шве ставить надо на R-это я так понимаю и есть 1 мм?

Fraxine На обычных швах в принципе 3 ,длинна стежка нормально,если длинну стежка ставить слишком маленькую,то шов будет не красивый да и расход ниток лишний,закрутка рулика на 1034 вполне хорошая,причём на R будет плотновато,визуально даже меньше миллиметра,лучше ставить немного больше.

Доброго вечера осинкам! Освоила свою новую ШМ (спасибо Шатл и все-все-все!) и вернулась к выбору оверлока/коверлока… и вопрос такой: бернина 880 или джуки 735 — как именно оверлок, что лучше, удобнее? разница в цене у них небольшая..

Уважаемые форумчане! Годик назад с вашей помощью выбрала себе машинку, за что я вам глубоко признательна, а теперь вот хочу «апгрейднуться» до оверлока. Оверлок первый будет, в первую очередь хочу использовать для шитья трикотажа (детские трусы-спортивные штаны, шапочки и т.п.)
Как вы считаете, Смогу ли удовлетворить мои потребности какие-то из нижеперечисленных моделей? Вопрос цены стоит довольно принципиально, потому даже разница в цене в 30% уже откладывает покупку в долгий ящик.
рассматриваю такие варианты:
Janome T-34
Janome 205D
Janome ML 204D
Janome ML 9002D
может, другие модели в этой ценовой категории порекомендуете?
в вопросе оверлоков я полный профан
