water, as it cant be compressed

just buy prebent pipe and cut it apart and make the bends you need.

You sound like a 13 year old..... You CAN fill a tube with sand cap the ends and make a bend.... Although just purchasing bends is the better way to go... I seriously doubt water would work the density of sand would aid the bending...

Yea, I've done the sand thing before. It works okay. The only time I've done it, is when I run out of mandrel bends, and I need something right then.

i tried it once and did not work for me. i would buy prebent pipe if you can. i have made jigs out of plastic electrical conduit and fitted them in for roll cages before. once i had them fitted i made the new one out of steel. works good if you have multiple bends

While we are in the conversation of mandrel bends, does anyone know where to get titanium bends? Im going to try and talk someone into doing a set of titanium headers.

Burns stainless, SPD Exhaust, Pro Fab.... Aircraft supply type companies Although Id build a set of Inconel headders...

yeah, i like inconel too, but I like the post weld color of titanium better. inconel is a crazy metal. I have welded a whole bunch of that stuff.

haha.

To the OP yes sand will work, make sure its wet theo. also bend it slowly over a period of time. Too much stress at once is like coming home after a long day of work & your gf telling you shes pregnant, it never ends up good. lol

U-bends are soo inexpensive its not funny, why would anyone want to bend them?

NO!!! You want to be sure that it's as DRY as you can make it!! Hell, throw the sand in a kiln or an oven before using it!! Pipe-bending with sand requires that you heat the pipe - and if the sand is WET, then you've just created steam (and PRESSURE) in the pipe, and that generally isn't a story that ends well...

In all honesty, the others who posted something to the effect of

have the right idea. Trying to bend a pipe using sand doesn't make sense unless you want the bragging rights of having done that...

(And yes, I know that this is a very old thread - I wouldn't have revived it except I didn't want someone following idiotic, dangerous advice & potentially getting seriously hurt or killed...)

I've seen the video of this, not sure it's be the way I would go

check some videos on U-tube for bending tubing .

actually packing wet sand in and using a hyd. pipe bender from harbor freight works... you dont have to heat, the whole point here is to not have to heat it. and YES i know because ive done it... its a long process to get around mandrel bends but on roll bar tubing it works flawlessly duct tape teh end, fill from the other end, duct tape that and bam you have a ready to bend pipe.
