pipe bender tips?

hey guys,

my parents picked up a hydraulic pipe bender from harbor freight over the weekend, so i could try and bend some exhaust pipe for my truck. mainly, to go over the rear axle.

well, i have 2" pipe. and there's a 2" die. we filled the pipe with sand, and everything, in hopes of not having it cave in on its self.

needless to say, we haven't had any luck.

SO!

if any of you guys have experience with pending exhaust pipe, or anything like that...please please PLEASE...shoot some info my way.

thanks in advance!

-Sam.

Re: pipe bender tips?

the cheapo pipe benders dont bend tubing worth a crap past 30-40degrees it will kink them beyond that point they dont do for rollbar tubing either

Re: pipe bender tips?

Cdowns, i found that out first hand. lol.

we now have a plan of bending a little at a time, to accomplish the rear axle loop, so to speak.

so, in stead of say, a single 45 degree, rather attempt two 22.5 degree bends, to try and spread the force out, and have the pipe not collapse and kink and all that nasty stuff.

any other suggestions?

i know the logical thing would be to take it to a shop and have them do it. but, i'm just too stubborn to do that. so! yes.

keep 'em comin' guys. pleassseeee.

let's hear it!

-Sam.

Re: pipe bender tips?

those style benders arent really made for exhaust tubing. they always will kink or collapse the pipe.its probably not worth the aggrevation nor the pipe your going to waste trying to bend exhaust with that style bender

Re: pipe bender tips?

I think you are on the right track with the bending a little at a time.It will probably cost you more in pipe than a new exhaust system but you will have learned the skill.I doubt you will ever be able to get a perfect system bent with it though.

Re: pipe bender tips?

The only way the sand really helps is to pack it in as tight as you can & weld the ends shut. Thats a lot of work compared to paying an exhaust shop a few bucks per bend to have them do it. Usually if you have the pipe & have the bends marked, they do it pretty cheap...

Re: pipe bender tips?

yeah....

i'm thinking you guys are right in regard to taking it to an exhaust shop. it seems like it's the most cost effective.

i'm gonna putz around with it some more, dad and i have some ideas, but, for now, we'll call it a draw between the bender and myself. i shall not yet admit defeat!

just shove it into a dark corner and go to the muffler place. lol.

Re: pipe bender tips?

not much pipe bending experience here but try any heat from a torch along the outside of the pipe while you bend? no-one mentioned heat so i figured i would.
