Default How-to: pipe bending (with tool info)

The other thread wasn't moved, so I guess this is the place for this kinda thing.

Continuing my contribution to google fodder...

I read through mx592's incredible build thread, saw hard lines custom bent, and wondered how unattainable that would be for mere mortals.

Turns out you just need a decent bender/cutter! Annnd a lot of patience/skill with measuring (made easier with welding rod models).

The Home Machinist! • View topic - The art of tube bending

This is a great read for those new to pipe bending. Goes over tools, methods, etc. It's centered around model (?) steam locomotives. They have boost, right?

The 'how-to' pipe bending stuff starts here: The Home Machinist! • View topic - The art of tube bending

If anyone has info on where to use/not use hard lines in a turbo/automotive application, or anything else that would help would-be DIY folk...I'd for sure like to know. And by know...I mean if nobody posts anything I'll do more googling.

Guessing only sections to/from the radiator or oil cooler would need flex lines to deal with drivetrain movement.

For tube bending this looks like a good read. How to Do Custom Hard-Line Bending- Hot Rod Magazine

I have the harbor freight tubing bender. For 6 freaking dollars I currently dont understand how the name brand ones could be hundreds of dollars better, but I'm sure they are.

After the scare with almost burning through my braided and fire sleeved turbo oil feed, thats about to become hardline.

For any hardline that's on the engine (like Leafy's turbo oil supply), use steel tube for fatigue resistance. I've seen lots of aluminum tubes crack.

hornetball, I remember reading that back when it was posted, thanks for the contribution!

Leafy, great read, thanks!
edit: Oh, and this is why different brands:
Quote:
Here's Bohlen's 15-year collection of hand-benders in a number of tube sizes and jaw styles. The various brands clamp the tubing in individual ways, allowing different shapes to be formed without the bent tube interfering with the tool itself. Don't buy electrical conduit benders.
