I want to take the bent step and bumperette off the bumper of my 40.
However they are welded on. Can I break/cut a weld with a hacksaw,
chisel, or butane torch; or do I need to take it to a welding shop?

Thanks.

grinder with a cut off wheel probably work the best. Hack saw might take while

X2 grinder is the best unless you can not get into the area. You can also drill it out if you have really good drill bits. Plasma cutter works too if you have one. There are people that can help you in the club including me depending on where you live.

A picture speaks a 1000 words, I can't remember how those are bend and attached etc.:confused:

I use the thin 4.5" slicing disks for things like this - cut most of the way through the weld, then bend the part, and snap the weld. Try not to cut all the way through the weld because you'll hack the metal underneath.

Then switch to a grinding disk and grind off the remaining weld bits carefully, to avoid hacking the 'cruiser behind the weld.

Buy a 4.5" grinder not 4"

Pics attached - one of the bent step and bumperette,
and one (blurry) of the weld itself.

Sounds like I have an excuse to buy a grinder!

That reminds me of some plates that were welded on to my front frame. I used a grinder to get them off and build my front bumper (http://www.risingsun4x4club.org/forum2/showthread.php?t=6780&highlight=bumper+grinder) out of c-channel. The work took much more time than I thought it would, but persistence paid off and the results were just fine.

Buy way more disks than you think you need. Good eyewear and earplugs. Wear flip-flops.

Why do people do that.... Jeez.

I just worked mine back and forth until it broke... Needless to say my PO was a crappy welder. On mine he welded the bumperettes/step to the bolts he had broken off. Lazy, but better for me in that he didn't weld it to the rear crossmember.

This is the mess I had to cut off using a grinder.

When the grinder slips don't catch it with your other hand. Learned that the hard way. :banghead:

I would check into the air-arc process to remove the welds then use the grinder to clean up. This process is much faster and cleaner than any other.

Phrog, If you haven't got these cut off yet and come by the shop (West Greeley) I'll cut em off for you for free. Call ahead though as we've been bouncing the shop hours around like crazy.

Thanks all for the advice and offers. I need to get handy with a grinder,
and this seems the opportunity.
