Aweman, I have a welding question, you there?

I want to reinforce my front differential mounts with the body in place. The diff will be removed. The area is pretty cruddy. What is the best way to de-crud this area to get the metal really clean before I MIG the mounts in. Hard to get a wheel in there to cut down to clean metal. Any suggestions on cleaning this area first??
 
If it is grease and the like you can remove that with a good de-greaser or solvent and a stiff brush. To remove rust, scale, paint and the like a pencil grinder comes in handy for tight places. Or even a dremel tool with the cable driven pencil grinder attachment. This dremel set has the flex attachment required to get into tight Places. and it is reasonably priced too. I have this and it comes in handy for many projects around the house.

Of course if you dont already have one youll need the dremel tool itself maybe you could suggest this to your wife as an xmas present, To be given early of course.

NOTE: Copy and paste this one it will work {Nevermind I fixed it}

If nothing else Use and A.C. stick welding machine and ER6011 welding rod it is designed to weld over/through rust, grease and scale. {not my first choice}
If you want to M.I.G. weld these pieces on then yea the area where the welds are to go needs to be as clean as humanly possible. {Bare metal if possible!}
I hopes this gives you some ideas
 
If you can still roll it out into the driveway, a hot water/steam pressure washer will save you a lot of aggravation. Gather everything else that needs cleaned, the patio furniture, engine compartments of all the other vehicles on the property, and go rent one. saves the solvent in the hair.

Boy, you are right about a live-steam pressure washer, but the car is on stands with no rear wheels or suspension in a tight one-car garage. Speaking of live steam, back in my military days (38+ years ago) the base where I was stationed had a giant coal oil powered steam cleaner at the auto shop for use by anyone. I got my barn-find TR2 up in the air and, using protective wear, steamed the whole underside of the car. Wow, EVERYTHING came clean. That was then, and this is now. Guess I will have to follow Aweman's advice and use lots of elbow grease as I will be MIGing the things in.
 
My first task at my current job was a two week long cleaning of the underside of a steam Railroad locomotive.

I used an entire bottle of shampoo in those two weeks. My hair was nice and shiny, but it wasn't because it was clean!

"back in the day" they would just drop the whole shebang up to the bottom of the boiler in a vat of steam heated lye. 10 minutes and it came out clean enough to eat off of. but then we don't have the Juniata river to dump what's left into.

Yea I'm afraid your left with just a scraper and a can of brake cleaner. ugh.
Been there, done that. Make sure you wear eye protection, don't ask me how I know that. :p

HOLY COW, I'm officially a "senior member"!! That'll give me a reason to strut :smile:
 
Bill, I wouldn't go to crazy installing the reinforcement gussets. If they are the ones that install inside the mounts, they, not the weld provide the support needed to prevent the bracket from collapsing. All you need to do is dress the outside edge of the bracket with a file and put down a good short penetrating bead on all sides, a little more then needed to prevent them from falling out. Cuts down on the amount of time for metal preparation and contortion on your part.

Just my two cents worth from a guy with bad eyes and back.
