Excellent explanation, thanks!

[@Talasas]

Very informative, thank you for making this!

[@theyear-pj4sj]

Great vid, helps engineers, thanks!

I've been making exhaust for years with mandrel bends for their true diameters. But I never knew how they were actually bent. Honestly, I thought sand or something would have been involved, lol. Excellent video.

[@murtazabhagat3743]

Can this method of bending be used for mild steel & cast steel material? As in I run a hardware store where we sell ERW & Seamless Short & Long Bends. Will this more cost effective than the conventional exhaust bends? The conventional bends are currently being imported from china.

Thank you for the Tip. :)

I built a mandrel bender for just a few thousand dollars, that’s a neat machine though. I could bend thin wall up to inch and quarter.

[@PurpleNovember]

What wall thickness? I’m looking into making one to bend 4130 chromoly 3/4 OD. 0.035 wall.

[@antuanperez426]

How’d you go about building it?

[@jaithesimpleguy]

Damn. Its like a superman hand, but much more artistic.

[@ymb3269]

What is the difference between mandrel with 2 or 3 discs or with no discs?

[@TrickTools]

It is all based around what material you are bending and how tight you are bending it. Transfluid will help the end user determine what type of mandrel is necessary for their specific application

[@BKMDano17]

When it comes to headers, why not just bend the pipe from one end to the other instead of making a bunch of 180s and cutting them up and welding them back together?

[@TrickTools]

If you have a mandrel bender at your disposal then that would be the best route. Mandrel bending machines are quite expensive and most shops can't justify the cost so buying U bends from suppliers that mass produce and sell them is the most cost efficient way to get mandrel bent tubing for headers.

Very informative, but when you follow the link for the bender that starts off at around $500, it's $895 MORE than that. $500 to $1,395 is a little more than a margin of error. Otherwise a good video.

[@TrickTools]

Thanks for watching and we are glad the information was helpful. The manually powered version of the Pro-Tools bender actually starts at $389.95 with a Deluxe kit available at $549.95. The powered version that you are referring to does start at $1395.

[@vinnbrock]

@@TrickTools thank you for the reply. I wasn't trying to be negative or mean. I just followed the link in the description, and it was significantly more than what was mentioned in the video. Do you have a link for the more affordable version?

[@TrickTools]

No problem at all, here is a link to the the manual version. www.trick-tools.com/Pro_Tools_MB_105HD_Heavy_Duty_Manual_Tubing_Bender_MB_105HD_5142
