Any help? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I pretty much have the Blazer torn down to parade rest. I'm finding more rust than I thought I would have, but still not too bad. My question is, I want to take the entire truck apart, fix the rusted areas and reassemble. I mean take it apart piece by piece. Cut out the spot welds and start over from scratch. Is this going to kill me? I've started on the cab and so far so good. I'll be dremeling the welds around the windshield and firewall area. Does anyone have any suggestions for making it a little easier? Is there an easier way to go about it? Besides the obvious and getting a different truck that is already done

Thanks for any help, Jeff.

anybody?

Don't know about the overall restoration but go and buy a proper spot-weld removing drill bit, they last much longer than a standard drill and do a real neat job of removing spot welds. Any good tool supplier should have them.

It helps to have some degree of fabricating/welding skill, as well as the proper tools and equipment. I frequently use wire wheels on my drill to clean surface rust. For that in depth rot there is no substitute for cutting it out with a die grinding wheel. Cut out the nasty stuff, clean it up and make/buy replacement patches/panels. A Mig welder (wire feed w/ shielding gas) is essential for replacing any metal. You have to assess whether or not fixing a rotten panel is easier and less expensive than replacing it entirely with one in better condition.

I don't know about those those touchy areas in the cab like around the windshield. It takes a lot of finesse to replace metal in there and lots of people have opted to replace the entire cab if that area is too far gone.

If you have any doubtful areas take pictures and post them on this board. I'm sure there are lots of folks here who can provide you with feedback and solutions to help you out. I also have lots of pics in my website below showing some areas I've worked on. My methods may be madness to some but still effective,

Thanks for the help guys. I am going to try and take it all apart and repair all the bad spots like I said. I have a mig welder, its not gas shielded and I'm not a very good welder. But I don't think that will be a problem, as practice makes perfect. How does the spot welder drill thing work? As far as I could tell there are spot welds about every 2 inches. Do you just fill all that back in later? Thanks for all the help, Jeff.

Spot weld cutting bit has raised cutting edge on either side and will cut a disc out of the first layer of steel, leaving the weld behind on the second layer. I heard they are brittle so be careful. The hard part is actually locating the spot welds. I managed just fine with a regular drill bit. Just drill in part way and the seam will come apart easily with a little prying. Then you fill it back in afterwards if you are putting that panel back in. If you are replacing the panel with a new one it might help to predrill holes along the edge to be welded then weld it to the mating surface. End result is similar to a spot weld.

Thanks Southpa. I'll try drilling them out before I use the dremel. I'll see which one works better. Jeff

this is where you can find the spot weld cutter (http://www.eastwoodco.com/cgi-bin/sg...02091818324098) go under welding, then to spotwelding and accesories, thats where you will find the stop weld cutter! Good luck with your project! -Brian
