What tool(s) are best to use for grinding and weld grinding in tight areas. There are some places where the 4 1/2 just won't work. Places like this after repair.

I think you're asking for something like this: Coarse-Finish Grinding Cones and Plugs [edit: link is redirecting. just scroll down to the Grinding Cones and Plugs] For really tight clearances you're going to need to go to a Dremel: Grinding Bits |

Like ehrawn suggests, a Dremel. The issue is not the diameter but the clearance for the tool. A grinding wheel tool is large (and the shaft too short) and could possibly come in contact with the tub or the bow socket when you attempt to grind. The Dremel has many attachments including a cut-off wheel (my favorite for metal work) that can be maneuvered into tight places. I will add that I had a few spots so tight that I had to use a grinding bit as the Dremel wheel was too large. I found out that the heat transfer doesn't sit well with the Dremel tool so work slowly and give it time to cool. |

Save the little pieces left when you think you've used all the good out of a 4 1/2 inch wheel. I also like to save the last piece of the cut off grinder wheel (thin grinder blade) for such places. But sometimes you'll have to use a dremel tool or a stone cone grinder in the end of a drill motor. |

Carbide burr on a long neck die grinder will get just about anyplace. The only thing I have found that they don't do well with is aluminum because you have to constantly clean the burr flutes-still work but very time consuming. |

thanks for the suggestions. Don't own a die grinder or dremel, but I'll start out with my drill. The McMaster page is very helpful. |

A Dremel tool will not have enough umph to grind down serious welds, so as Ken suggests, buy yourself a good pneumatic die grinder and you'll never regret it;(new ones aren't really all that expensive, but if you don't want to put foot the bill for a brand new one, good used ones can be found at most all pawn shops for less than half of a new one). Dremel tools work quite well on thin sheet metals, like 16 gauge, etc., but they're too lightweight to handle the welds you show in the photos. There are several models available at Lowe's stores ranging from $49 on up, plus a wide assortment of different tools, grinding and cut-off wheels, etc.; I recently bought the $79 model to do some cutting and grinding on a previous owners rough cut-outs in the dash of my CJ7. |

I purchased both my 1/4 inch straight and 90 degree die grinders at Harbor Freight for less than $10 each. I have used them both now for over 10 years on a weekly basis. I did not purchase the extended warranty that Harbor freight always offers and they have never failed to perform. I put a few drops of what ever light motor oil I have around and they just keep on ticking. I use drum sanders, carbide bits and one of the tools came with a 1/8 in collet as well as the 1/4 inch collet so it will spin roto zip bits. The roto zip bits I find usfull in cutting irregular shapped holes in aluminum sheet and thin 16 guage steel. These roto zip bits are made for cutting sheet rock and are available at home big box stores everywhere. A mandrel can be bought that holds the 3 inch cut off wheels and can also be ran in the die grinder. You do need a good compressor to keep up with aa steady work load I have bot a 170 PSI and 150 PSI compressor. All of these tools pay for them selves in short order. Please use your Goggles these things could blind you in an instant |

I ordered an electric die grinder from Harbor Freight today. I think that will do nicely. Thanks for all the advice. Jeep Freak, I injured myself early on in this project, fortunately I healed up ok after a visit to the doctor. I always wear the googles, and gloves, and mask when needed. The heavy gloves saved me once when I slipped up with the cutting disc on the angle grinder. I also always unplug my tools when changing bits or tooling. That's a bit of a pain, but I can only imagine what part of my body the wrench from my 4 1/2 inch grinder might end up in if I inadvertently hit the on button while changing tooling! |
