try this

By the look of the pic: It broke where the lower links attatch, and the axle rotated down, correct?
Wow, those coil-overs are fawked! Ouch $$. I think the Pirate thread needs to be resurrected about the ****ty welds/fab work poison spider does....

[Doug Krebs]

I saw hal's bend like that and they went back to normal, I hope they didn't get hurt... I saw something on pirate that doug wrote that said ya'll are going to compete in farmington this weekend? If so, have ya'll started working on the jeep again?

Whats the rest of the schedule for the competitions?

From what I read on Pirate, this is just hearsay, but the crossmember ripped off of the frame due to lack of penetration on the welds, a brand new Bruiser, also built by Poison Spider, is said to have suffered the same fate at that event as well.

[uglyota]

why is the muffler mounted sideways? All that work to make it TPI then put two 90* bends in the exhaust?

[Fredo]

Well, it didn't really break at the welds. It broke the crossmember right past the weld. Welding aside, it was a ****ty design that shouldn't have left the shop. As far as the coilovers are concerned, they were discussing replacing the shafts on them to see if they could be saved.

Well, for one, the exhaust was already ran before the TPI, and secondly, those are 90* mandrel 3" bends. If it can't breathe well enough through that, then there is definitely a problem.

ah, so they had two pieces of 3" mandrel bent pipe laying around and just had to use them, and the first thing that came to mind was "mount the muffler sideways!"

I was asking what it had to clear that it needed to be bent like that.

Mandrel, schmandrel, making the air turn a corner still causes turbulence and slows it down (however, I understand that this is okay if it's being used instead of smaller pipe to achieve the correct amount of backpressure).

When are you gonna tell us what was wrong with that toyody?

Could lack of penetration be associated with a welding "technique" that uses a series of cold starts instead of a continuous bead?

[Matt Conlee]

The welds have been cracked on that crossmember since the snow trip we took last year in Colorado. I hope you guys get the rig ready for the next comp sounds like yall wouldve done pretty well if it wasnt for that.

Rig Update

The rig is at Sunray right now and is being fixed so it won't break again. As far as the welds they held and there is a hole in the frame where it was welded. It really needed to be braced more to hold up to my abuse. Tom was able to straighten the shock shafts until I can get new ones. I will be picking it up this Friday so I can do some front axle work then leave for Farmington on the 28th.

Did the cross member break in the HAZ of the weld? If so that is still a ****ty weld even if it didn't break at the actual weld. Wrong rod, to much heat, wrong pre-and post- treat can all cause the area to break.

I'm pretty sure it was MIG, and Jimmy can tell you why thats better

I think the start/stop stuff kept the piece from getting hot enough to get a good weld. In that class I took, the instructor was saying during the first part of the weld you're heating the part up, then when its hot enough you change welding techniques so the HAZ isn't as brittle.

Or maybe that kickass TPI setup just had to make the Jeep its *****

[aggiemudman]

what welding class did u take? ive been lookin for one but dont know if there is one or not.
