Nice article and sexy shorts.

 

thats nice

 

Interesting read but this is will haunt welding/fab forever

 

Isn't that kind of how they make mandrel bends? fill them with sand and bend them? but without the heat?

 

Oh no.

HAHA, no

They insert a "mandrel" into the tube so that when the tube is bent it maintains it's structure.

Like here:

 

Ahh, ok. Interesting enough.

 

Neat...DIY mandrel exhaust ftw

 

Definitely have heard of this technique, but that's a pretty good article. I have never seen actual pipe bent this way. It looks to be good quality. Might be worth trying.

 

Wow, I can't imagine bending up 12" pipe that is 1/4" thick this way. Man I bet this guy has some cool stuff sitting around

 

Great article. I have some friends with vintage race cars that told me about the old school way to bend header tubing.

 

very cool

 

Wow i think i have to try that just for the fun of it

 

REMEMBER TO USE DRYED SAND!!!! otherwise the pipe WILL explode.

I have tried to bend some 2.5" exh piping this way, but it didnt really work out. It defenately isent as easy as it looks.

 

i've done similar things with my hydraulic radius bender, never with heat and muscle though haha, i'm way too lazy for that ****.

 

article makes it seem way too easy. bet there's more to it otherwise no one would bother buying mandrel bends

 

i dont see too much "easy" in that article.. looks like it would take a pretty good amount of time and work to get a bend you can buy for not tooo much more than straight.

 

thats nice is u need a really specific multiple bend pipe.But otherwise, its cont that cost/time effective.

 

Seems like a really good idea. Pack the sand in tight, weld on end caps, then bend that ish in your crappy die pipe bender. Should come out better than the die bender alone, right?

 

It should be said, this method is not safe for roll cages

 

I know it has already been stated, but please USE OVEN DRYED SAND, otherwise you are working with a bomb.

 

looks good, i wonder if i used the sand for a regular pump/ crush bender

 

I tried this a few years ago I ended up with a garage full of sand and messed up tubing hes gets BMF award

 

is it possible to just torch the moisture out of the sand, or does this need to be done in an oven?

I might try this out, it'd be nice to know how to do this. Just doing some 2" pipe for my wagon so I'm not running an open cat
