Cutting Stock Bumper

Getting everything ready to install my new CBI front bumper. Was just wondering what others have used to make nice clean cuts on their OEM bumper - tool and blade type.

Sounds like my dremel would only melt the plastic. I have a nice jig saw, but was wondering if an angle grinder or body saw would be better (and give me an excuse to buy a new tool).

Thanks in advance!

I'll be in the same boat any day now. From what i've read a cuttung wheel or a fine tooth, high speed jig saw are your best bets. I think CBI recomends a cutting wheel. I recon as long as you tape it up and go slow either should do just as well. And get some weather strupping to finish the final edge for a profesional look.

But let me know what you end up using and how it goes so I don't screw mine up when the time comes!

Will do. Thanks for the reply. Anyone else? I was thinking of maybe trying one of these....

Do not use any tool with any sort of wheel, it will just melt the plastic. Lay down a couple layers of painter's tape, mark your lines, then use a jig saw with a high tpi metal cutting blade.
 
I used the Dremel 670 Mini Saw Attachment with 4.1 out of 5 stars on Amazon - Price:$19.60

It worked fine with clean cuts and then I sanded a couple of rough areas and it looked factory.

Honestly I made most of my straight cuts on the rear bumper cover with a boxcutter. If I had it to do over I would have used one of those hooked blades so I could have had an easier pull. I only broke out the Dremel and some black cutting discs when I had to go around the tailgate area. All the melted plastic cleaned off very easily with the boxcutter blade afterward.
 
i used a dremmel tool with the thin cutting disc to cut my front and rear stock bumper with no problem. you just have to tape your cutting lines and keep a steady speed.

The oscillating saw is the best. Cuts like butter and is easy to control since it has speed control

What size light bar fits in that cutout?

It is a 30-inch single row Hausse LED lightbar that was one of the options on the Southern Style Slimline bumper group buy held in the early summer. It works OK, as I didn't really need one as didn't think I would use it often, but it was only around $200 after the discount so I thought why not. I like the look and it is handy off-road as the sun begins to fall below the mountains early this time of year on the trails.

Where did you get the rubber trim used around the bumper after cutting it?
 
I recently trimmed my bumper with a sharp box cutter/utility knife, started slowly using masking tape as a guide and scored it repeatedly until I got a good groove that I could use to apply more pressure.. It is easy to accidentally get off of the line though. I also tried out some sheet metal shears which seemed to work okay.

Practice on the scrap part of the bumper and figure out what works for you, rotary tools tend to melt the plastic a bit from my experience.
