One thing I like about building a true custom (not just bolting on shiny wheels and putting stickers on the windows) is that there are no rules. It's all about what looks good and what fits your vision of the final product that is YOUR project. One theme that I have with Project Pile House is to make the body less "busy" and give it a smoother overall appearance. These trucks were meant to be utility vehicles, so there wasn't much thought put into styling. Definitely not like their passenger car counterparts. All that anyone really cared about was that it was reliable, could haul a lot in the bed, and that the hood, doors, and tailgate closed and latched. So this means I need to fill and smooth a lot of body seams or body lines that are all over the cab and front end.
These seams need to be filled with metal, and should not be filled with body filler, no matter how tempting it is to just run a bead of filler along them. Occasionally you can get away with filling a seam by slowly stitch welding it shut, but this could require a few passes to completely fill the seam and it puts unnecessary heat into the panels around it. I've found that these seams can be easily filled by using TIG filler rod and a MIG welder. This tech tip should help you fill body seams quickly.
You want to start by removing any paint or rust around the seam, and then run a wire wheel in the groove to remove anything tucked into tight crevices. I found an angle grinder with a flap disc takes care of most of the process, but a thin wire wheel cleans out any remaining debris. If you're the overly cautious type you can spray some Self Etching Weld Thru Primer in the seam to help seal the area.
After you're down to clean metal, you'll want to find a TIG filler rod that will fill the seam and sit flush, or just below, the surface. You then want to set your MIG welder to a higher voltage or heat setting than normal for the metal you're welding. The idea is to produce a quick, hot spot weld that melts the filler rod into the seam and leaves a fairly flat weld on top of the panel. The flatter the final weld is, the less grinding will be required.
After you have a few spot welds holding the filler rod in place, you can then stitch weld the rod into the seam. Always remember to alternate your spot welds and allow the panel too cool in between welds. The seam should look something like below after it's completely welded.
With the seam filled, you can take a flap disc or low grit sanding disc and knock the "proud" welds down until they blend into the surrounding metal. You should be left with a seam that's filled with metal (and not filler!) and will require little bodywork when it comes time for paint.
So you decided to give your car a refreshing new look and it's time to strip it down to prepare the car for paint. You can count on finding some sort of surprise when tearing the vehicle down. Whether it's hidden accident damage, previous repairs, or the mummy of a dead animal; it's always an adventure when stripping a car or truck down for paint or bodywork.
I recently started tearing into my "clean" (for the east coast at least!) 1977 VW Scirocco I've owned for a few years. It had some wear and tear and some bubbling paint I wanted to address before it got a fresh lick of paint. When I began removing the fenders I was pretty surprised to find some rot in the inner fender and windshield cowl. I decided to take some photos as I repaired this area and share some tips for making a repair that will look original when done.
Here is the offending area when I removed the fender. The worst rot was in an area that sandwiched between the fender and cowl and was covered with weather stripping. So from first glance it just looked like some bubbled paint, but that was the tip of the iceberg.
I first cut out the area that was rotted until I got to solid metal and a nice seam where I could weld and blend the panel into the original metal.
I started making my patch panel by bending up a piece of construction paper to the rough size I needed, then I transferred the rough shape over and cut it out of 20 gauge aluminized steel. Next I measured the other side and marked out the bend line I needed to make.
In order to make a clean bend in the new metal I needed a metal brake. I decided to use the Versa Bend Sheet Metal Brake and put a crisp 90 degree bend in the panel on my line.
With the patch panel now formed into the rough size I needed, I took it to the car and trimmed it to fit the opening. It's here that you want to make sure the patch panel fits tightly so that you don't need any excessive welding to fill voids.
I then setup the MIG 135 with .023 Solid Core MIG Wire so I could lay small, flat spot welds on the patch panel. Setting the machine up on a similar piece of scrap metal helped me get my spot welds laying flat and penetrating correctly. After finessing the panel with Eastwood Hammers and Dollies and blending the welds with a flap disc on an angle grinder I was satisfied with the repair. I'm happy to say the patch panel looks close to original and the repair should be invisible once it has primer and a top coat on it. Now onto the next surprise!
Introducing our new line of "Lady Eastwood" MIG Welders! Just kidding, but...
It might be a little difficult to think of your wife underneath a welder's helmet, but more and more women continue to get into the field. In Australia, for example, the Queensland government launched a new "women-only" program in July that would help alleviate a shortage of skilled welders in the province.
The pilot program of "Women Who Weld" has already started with its first class of women welders, ranging in age from late-teens to mid-30s. At the end of the course this fall, they will each receive a Statement of Achievement, and will have progressed towards the completion of three units of competency from the Certificate I in Engineering qualification.
Of course, in the United States, women have been in the welding workforce for decades, at least as far back as World War II. As of a few years ago, women made up 6%-7% of welders, and it's been pretty steady since. Many in the industry believe there's no reason women shouldn't be in the profession, especially since they possess the characteristics of a good welder: stable hands and scrupulous eyes.
When you think about it, this is a great way to get your wife, girlfriend or daughter to participate in your favorite hobby! The family that welds together, stays together!
