How to fix a bent barrel extension?

[Olle]

Heat will sure make things easier to bend, but it's a very dicey proposition if you don't know exactly what kind of steel you have and how it was treated after machining. It sure doesn't hurt (and would probably be beneficial to prevent cracks) to bring it up to like 150F or so, but I'd be afraid to heat it to the point where it becomes soft. Whatever kind of steel this is, it will probably lose temper, and so far I haven't found anyone who knows exactly how to heat treat it after bending it hot.

This is a very thin area and takes a lot of stress, and I'm afraid that the "heat til it's soft and bend" method will weaken it. Also, once heated above a certain point (above the usual "cherry red" you aim for when hardening), the properties of the steel can change to the point where it can never be brought back to proper temper. Bending cold is not the best method either, but it feels safer than heating.

My quote is from an American movie "Cool Hand Luke" about an American malcontent who is rebelling against society. He is arrested for damaging government property and is sentenced to behavior modification by physical labor. He rebels and attempts to escape. The quote is famous because it illustrates his inability to understand and conform.

It is the translation of your native language by Google or Yahoo that is confusing.

Here is what is confusing in your post -

Preheat gas - a site circled in black.
OK, that seems to mean heat the black area with a gas source [torch].
Insert the iron bar (green) is equal to the size of 12.9 mm, the item should be cool with a green bar.
OK, You're inserting a 12.5mm 'wedge' after the area is heated.
Heat to 3-4
We do not have anything equal to "3-4" in our measure of heat.
When heated metal recalls his condition pervonochalnoe
We do not have a word/translation for "pervonochalnoe".

Now, to your picture -

When heated to insert here the iron bar thickness
of 12,9mm
and so nsdelat 3 times, the surface will cool the air
and take your size
We do not have a word for "nsdelat".

From what I can decipher, you are suggesting heating the chamber area and then sliding a wedge into the 'fork' to return it to it's original shape. Do it three times??? And maybe the '3-4' is hundreds of degrees Celsius???

Nothing separates us like the language...

My attempt in Russian [via Google] -

Майкл -

Моя цитата из американского фильма "Хладнокровный Люк" об американском недовольный кто восстает против общества. Он арестован за порчу казенного имущества и приговорен к модификации поведения физическим трудом. Он восстает и пытается убежать.Цитата известен, поскольку он иллюстрирует свою неспособность соответствовать.

Это перевод вашего родного языка Google или Yahoo, что сбивает с толку.

Вот что сбивает с толку в вашем посте -

Разогреть газа - сайт обведены черным.
Хорошо, что, кажется, означают, что тепло черная область с источником газа [факел].
Вставьте железный прут (зеленый) равна размеру 12,9 мм, пункт должен быть прохладным с зеленой полосой.
Теперь твоя вставки 12,5 клиновидные после зона нагревается.
Нагрейте до 3-4
У нас нет ничего равно "3-4" в градусах.
При нагревании металла вспоминает свое состояние pervonochalnoe
У нас нет слов / перевод "pervonochalnoe". : (

Теперь, чтобы ваши картины -

При нагревании до перенесите сюда толщиной железным прутом
12,9 мм
и так nsdelat 3 раза, поверхность будет охлаждать воздух
и принять ваш размер
У нас нет слова "nsdelat".

Из того, что я могу расшифровать, вы предлагаете нагрев камеры, области, а затем скольжение клин в "вилку", чтобы вернуть его в его первоначальной форме. Сделайте это три раза?? А может быть, '3 -4 'является градусов по Цельсию??

Ничто не разделяет нас, как язык ...

Probably heat can and will help... but I really don't think it necessary for the small amount of correction needed... When I was a puppy, I worked on many, many small, mostly two cycle engine, outboard motors, snowmobiles, motorcycles, lawn and garden, and on and on... And one thing I remember that was always fascinating, was straightening a bent connecting rod... you could bend it quite a ways, both back and forth, until the piston was true to the cylinder.. no compromise in strength or life of the part... I don't think these receivers are any better metal or temper, and I've had more trouble supporting them correctly, then in bending the part... A real issue, is if it's slightly crushed??? We will see as I have it in my hot little hands right now! Again, not for the faint of heart........ I will report back soon with either happy smiles, or big crocodile tears?? Best to all til...lat'r....GT
