Wire wheel and flap disc help

I bought some more tools! YEAH!! These are the tools I am using to strip my CJ5 frame... the same mess in this thread- http://www.jeepforum.com/forum/f8/be...-paint-774919/

From left to right-
The first wire wheel is called a crimped wheel.
The second wheel is a braided wheel.
Then the 120 grit flapdisc.

I have already used up a braided wheel. I saw the crimped wheel and wondered how it would work for stripping or scuffiing. I have never used a flapdisc. I would like to hear your experiences with these tools, and the proper applications. I have only used a braided wheel on the frame.

Thanks in advance.

Flap disc will get you the best possible results...bare metal.

Just put the flap disc on the angle grinder and start going at it. Nothing special and definitely not rocket science.

A flap disk in 80 grit will get you the best results for stripping. The crimped one us on rust the braided one is a little hard to control.

The first one is a waist of time and the flap disk will take to much metal with it. A "twisted knot cup brush" the one in the center is what you want to use. Just throw it on your 4 1/2" grinder and go to town. If you have axcess to a 9" grinder and a 6" cup brush you can save some time. It will be dirty and dusty, best to do it outside.

I've always had the best luck with the straight 4.5" knot wire wheels on my angle grinder. They last longer and really strip things fast, then you can follow up with a 80-120 flapper disk to clean up any pitting. Plan on using 3-4 of them to strip a complete frame. I used one of these $5 ones from Harbor Freight and got through about a 1/3rd of my frame. I went to Farm & Fleet and bought their equivalent brush for $13 and it didn't last even half as long. If I remember correctly it took the one from HF and three from F&F to finish my frame. I wish I had just bought ten of the HF wheels right from the start, I did buy six more the next time I went back. I think I have two left. These wire wheels and my welder are the two HF tools I will back all day long.

Whatever way you remove the rust and paint you need to keep the dust from it out of your lungs.

My flap disc is 120 grit. I went conservative, but after using it tonight I think I will go more aggressive. You're right, bare metal and pretty dang quick!

Yeah... the braided one likes to "walk" around. I am on my second one. I don't like how it smears through the old undercoating, but it's good for getting all the loose stuff off.

It made a mess all over my shop floor. Tomorrow, it is outside!

I looked at those at Lowe's this afternoon. I didn't buy one as I didn't know anything about them. I imagine control would be much better. I'll pick one up. I have a lot to remove.

I haven't tried them. To me it's a little pricey, but it looks like good stuff.

I use the same wire wheel as Coiz and buy them at Harbor Freight, about 4.99 apiece. They seem to last quite a while and if I remember correctly, I on only used 4-5 on my frame.

I take the guard off my angle grinder when i use the the wire wheel but I wear a shield too. Still dig wires out of my skin and clothes though.

For the flap discs, I like to use 36 grit, the finer grits load up with paint and don't cut as well.

Yep, have had a wire in my eye...got lucky!

Had a wire or two in my balls, have not tried a cup but it might be worthwhile

HF in Valdosta... wifey says she'll go up there and get the wire wheels for me. I've followed your thread so I know that you know what you're talking about, but 36 grit in a flapdisc sure seems real aggressive! I agree that the fine stuff loads up... I experienced that tonight, but I don't want to remove too much. Is 36 the best route? I have completed half of the frame with the braided cup wheel. It removes the loose stuff, but then it kind of polishes everything. Should I take the flapdisc behind it? How do I get the gummy undercoating off?

I got an '85 CJ7 that was a plow jeep in Alaska, and after spending 8 hours with a sand blaster, 4 hours with a wire sponge wheel and 30 minutes with hand sand paper, I was ready to throw the brackets out. Then I was in sears, saw a flap disc and got it because I was desperate. It worked wonders, got through everything quickly.

On top of the eye protection you'll want to wear some type of mask. Breathing that crap in is no good for the lungs.

Looking at them in the store, I thought flapper discs were a joke. Buddy convinced me to try them.

All I use now. I tossed all my other clean up and grinding disks. Only cut off wheels and flapper discs. HF will run specials and sell the 60G in packs of 3 for 5 bucks or so. The name brand ones are better and last longer, but they are not 450% better.

my family and i used the flap discs on some angle grinders to do the entire body on my 5, worked like a charm and only took about 2 days working on and off. I can't give my results for the frame, we sandblasted that. The braided wheel worked extremely well on the underside of the tub to get excess dirt and stuff off.
