Hi..New here, found this place while looking through Google trying to find out how to fix a small bend in my new skid plate.Basically, it got damaged during shipping and I have absolutely zero clue about how to fix it as I don't know anything about this type of stuff. Is this something I can fix myself or should I go to like a metal shop(what would that even be called?)I didn't want to start hitting it with a hammer as I don't know if that will weaken the weld(again I don't know anything about this type of stuff.) However it is a skid plate so should be able to withstand some pretty powerful forces.Anyways, thanks for help in advance!KN Attached Images

Reply:Clamp a bar/tube to it that is 5' long or so and bend it down.
Reply:Remove the bolt, put it on a flat solid surface(preferably steel) and give it a few good whacks with a 2-3# hammer. You sure it's not supposed to have that bend in it? You might want to look where it is going to be mounted to make sure before you try straightening it, otherwise you may be back asking how to put the bend back in it.
Reply:looks like the bend is suppose to be there..if you know nothing about it, who is going to install it ? mabe let them look and see first..Of all the things I lost I miss my mind the most...I know just enough about everything to be dangerous......You cant cure stupid..only kill it...

Reply:If you don't like the hammer idea, Bolt it to a solid service and use a '' c '' clamp to draw it down. It may require a shim to elevate the main piece if you can't get it flat enough.

Reply:Heat the bend area to red hot with a torch and slowly bend it back in shape.  Hammering might not be the best approach considering the weld.

Reply:I dunno, definitive looking die mark there Bro. I would still fit it up and double check before heating/bending. Depending on the size of the manufacturer, the customer rep might not know squat. Small outfits seem to be more personable/knowledgeable, but not always the case..If in fact you fit it up and find that it does need to be flattened, see if you can find somebody with an extremely large cresent wrench / pipe wrench / or find something that can act as a large cantilever. Secure one side, while you slowly pull it flat a little at a time till it's flat. If all goes to hell, call the manuf back and tell em you need a new plate.-NicheLast edited by NicheFab; 01-22-2015 at 11:46 PM.
Reply:Best way to straighten that is from the bottom. Put the pipe section down on something solid and strong like an anvil, bumper or large rock. and strike it with a heavy hammer or smaller rock. If it doesn't move use a heavier and bigger hammer.  Just make sure to remove the bolt first.  Most likely will need an extra set of hands to hold it in place very awkward shape to hold and strike at same time.   Good luckMeasure with a micrometre, mark with chalk,  cut with a torch.Never force anything...just get a bigger hammer.RoyOld Airco buzz box approx 1974Lincoln mig pack 15Lincoln 175 square wave1954 9" south bend lathe
Reply:If you had someone with a suitable set up, you could heat the bend on the back/bottom across the bend, then let it cool. The heat will draw it back down when applied to the right side. If it were me I woulda smacked it with a hammer. That or put the bent part in a vise (a good one) and used ths tube its welded onto to pull it back up as much as possible. If thats even an option.
Reply:Wow! Seems like an easy fix to me if it was in fact bent. It does look like it has a distinct bend mark from a brake so maybe there's nothing wrong with it? Heating mild steel to bend it doesn't affect the strength. A lot of straightening is even done by spot quenching heated area's. CEP could give lessons on straightening but for this particular part I don't think any heat is needed. Take the bolt out and use it to bolt (or clamp with a good strong clamp) the piece onto something solid like the ball mount on a trailer hitch and then just use the pipe as it's own leverage to straighten it cold, like was mentioned above.
Reply:kn6If you walked in my door - I would accept shipping damage as the cause. Although your photo is off axis - the upper/right 'kink' is perpendicular to the tube - and the lower/left 'bend'is obviously diagonal [misaligned] and not a productionfeature. Because you are not equipped - go to the most reputable 'Job Shop' [not manufacturing] in your area.Ask: that they construct a fixture while cold - heat with a 'Big-Azz' welding tip [top & bottom] - then clamp to flat.Tell them you don't want a hammer used for the draw, and that you expect to pay their shop rate - T & M.Your metal: is production welded A36/A500 and doesn't present any lingering temper problems when heated.Opus
Reply:Hammer it straight or use a big crescent wrench.  If heat is needed and you don't have a torch a throwaway MAP gas plumbers torch would heat that hot enough to bend back with a crescent wrench.  Looks to be only 1/8" thick material.Miller 211 MIGThermal ARC 186 TIGHypertherm Powermax 30 Plasma

Reply:In order to heat steel to bend it, unless it's 1/8" or less, a plumbers torch won't get it red hot where it would bend easy. You need an oxy/fuel torch to get the required heat. Heating it hot might burn you but it doesn't make it bend easier just because you can't put your hand on it. If it bent that easy, it will straighten just about as easy. Put it in a vice or clamp it to something solid and try to bend it cold before you do anything else. Why make it more complex if you don't have to?
Reply:Check for fit, then take it to a local shop, will cost uou little, you still have to put a finish on this right. Best Sent from my SGH-I747M using Tapatalk

Reply:This is a whole lotta discussion about a tiny piece of bent steel...   I'm also having a hard time believing that someone with the confidence to install custom parts on their vehicle would be baffled by a non-issue like this....

It jumped right back into place.
