Yet another sheet metal cutting question(s)
I think I am going to get the DeWalt DW 890 shear. And an American made air
nibbler. The IR nibblers are about 4x to 6x the price, but I have heard of too many of the Chinese ones dying an early death from work. Is there an alternative to the higher priced IR, or should I just buy the good one and cry once? I also looked at the Ketts, and they are a good chunk more than DW or Milwaukee. My budget on this is about $350 for all three, and I am going to get a rebuilt DW, as these will only see "normal" use. Now, another question. The scissors are for long lines, right? The nibbler is for nibbling 1/8" or so chunks for fine and finishing work, right? Looks like they dress up edges and don't have much of a throat. And just what are the ones that have two jaws about 3/4" long, one stationary, the other going up and down? Would that be for long lines and broader radiuses? And similar views about a not so deep throat. I like to understand what I need, then I go shop price. I think I've narrowed down the brands, now will shop for price, and buy according to priority of need, the scissors first, nibbler second, and the whatzit third, if I decide I even need it once I see what the other two can do. Thanks in advance. Steve |

Thanks in advance. Steve Steve The nibbler is for tighter curves than either of the the others. The mechanism behind the cutting edge is narrower than the cutting edge so it can cut through a piece wider than the "throat". Never used a power nibbler, but they make, or used to a hand powered version. CarlBoyd CarlBoyd |

--Have you seen Beverly style shears yet? Also I'm thinking if you
can do template cutting you might want to rough out your shapes with a plasma cutter, then use a bench mounted power nibbler to finish the job. -- "Steamboat Ed" Haas : Steel, Stainless, Titanium: Hacking the Trailing Edge! : Guaranteed Uncertified Welding! www.nmpproducts.com ---Decks a-wash in a sea of words--- |

Also I'm thinking if you can do template cutting you might want to rough out your shapes with a plasma cutter, then use a bench mounted power nibbler to finish the job. Just keep in mind..that like a torch..a plasma cutter leaves a Heat Affected Zone in the area of the cut. It might be smaller than that of the torch..but it IS indeed there. Sometimes its better to cut a fair amount larger..and then use the Beverly to cut inside of that HAZ area. Else you are trying to cut heat treated material Gunner One could not be a successful Leftwinger without realizing that, in contrast to the popular conception supported by newspapers and mothers of Leftwingers, a goodly number of Leftwingers are not only narrow-minded and dull, but also just stupid.
