When it comes to auto body patch panel installations, no joint is more useful than a flange joint. A flange joint is very similar to a lap joint except that the area that is overlapped on one of the metal pieces is lower than the rest, making both pieces at equal elevation when welding. ....

The 1940 Ford Coupe has always been a popular car for restoration projects, ever since World War II veterans began turning them into hot rods by adding performance equipment to the car’s flathead V8 engine.
But you no longer have to poke around in junkyards or barns looking for an original to work on. Now you can buy a brand new 1940 Coupe body directly from Ford!
The 1940 Ford Coupe body is produced with today's high-strength steel, and is assembled using modern welding techniques. The new body comes rustproofed from the factory and is ready to be assembled as a custom hot rod or as a reproduction to the original.
You can choose a stock firewall that accommodates the original flathead V8, but it can also be ordered with a recessed firewall to allow installation of much larger modern engines. Ford also supports it with a variety of model-correct mechanical and trim restoration parts; to see what's available for the 1940, click here.Click Here To Read Full Post...
After getting the old swiss cheese firewall removed from the truck I started making the new firewall for Project Pile House. I started by having one of our tech advisors Sean help me make a cardboard pattern. Once the pattern was made we scribed out the shape onto our metal using a pick from the Eastwood 4 Piece Puller/Scraper/Pick Set. I decided I wanted a smooth firewall for a "cleaned" look. Because of that I won't be running beads in the firewall so I opted for 16 gauge sheet metal.
I wanted to make clean cuts in the metal so I decided to put our Electric Metal Shears to the test and make the majority of the cuts with them. I know we only rate them to 18 gauge, but I had heard rumors that these were actually tested up to 16 gauge with no issues. I was pleasantly surprised that the shears (with well-used blades even!) cut right through the 16 gauge with no issues. I can't say how pleased I was to make those long cuts quickly with the shears. I then fired up the Versa Cut 40 Plasma Cutter to make the cuts for the radii on the tunnel notch and top outer corners. I made the cuts in a single pass with the machine on 110V at around 18 Amps and 60 PSI.
Now that I had the basic shape of the firewall cut out I did some minor trimming to make space around the headers and the valve covers for engine movement. I next made some "witness" marks in the firewall and the truck to have a quick way to match up the firewall each time I fit it. I want to make the transition into the firewall tunnel as smooth as possible so it gave me a chance to try out some new prototype tools we've been testing. We're currently working on a set of universal vice-mount T-dollies that I thought would be perfect to tip the edges of the firewall where transitions into the tunnel. The trick with these is to allow the metal to hang just over the edge of the dolly and use your body hammer to form the metal around the radius of the dolly. The result is a smooth bend in the sheet metal. Look for these to be out sometime in May or June!
By tipping and rolling the edges on the transmission tunnel transition I also added some additional rigidity to the panel that I could feel instantly after I was done hammering. I decided to test fit the panel again so I could mock up the top panel of the tunnel next. The top panel needed to have the same contour as the opening we cut in the firewall and the only good way to make that was by using an english wheel to roll the contour into a piece of sheet metal. I began by making a pattern to match the cutout in the firewall so that I could check my progress as I went. I used our new prototype Eastwood English Wheel to roll the mild curve into the panel and after a few a minutes I had a piece shaped appropriately.
I then used a couple clecos to hold the top panel in place. The fitment is pretty good and it should all blend together pretty nicely once it's welded. I still need to tackle the rest of the tunnel and begin mocking up the steering column and brake pedal before I can finally weld the firewall in place.
Just today I got some steering column parts and a frame mounted brake pedal assembly from Speedway Motors, so I should be able to steer the truck from inside the cab shortly. I've already got a nice chrome Right Stuff Detailing GM mini brake booster and master cylinder sitting on the sidelines ready to mount up once the fabrication is done so I can make Pile House stop too! Stay tuned, things are getting interesting!Click Here To Read Full Post...

Every since the first sleek new 1949 Mercury hit the street crafty restylers have lusted after examples with the roof a bit lower than the factory offerings. Sam Barris was among the first to chop his own personal Mercury, and the process would be repeated thousands of times over the next seven decades. Just as the word “custom” implies, personally designed customs each have a unique style and equally unique method of creation.
The guys at Hollywood Hot Rods have built a series of much loved custom vehicles so it’s only natural that they would have chopped a few Mercury’s along the way. Refining the process to a science, Hollywood Hot Rods get the job done lowering a lid on a Mercury (or any vehicle) with the help of various tools from The Eastwood Company. For this demonstration an Eastwood Shrinker/Stretcher is used to get a few of the vital steps in the process completed. Follow along as Hollywood Hot Rods shows how they lowered a roof on this 1951 Mercury.
Chopping the top on a Mercury is so popular at Hollywood Hot Rods that they have to wait in line for their turn under the knife.
The easy part is removing the top, the tough part is putting it back on correctly.
After lowering the roof the desired amount, the corners of the windows now require reworking to close up the gaps created in the process.
This view shows the great deal of work that will be necessary to reshape the rear corners of the quarter windows.
The first step is to trim out the rear corners so that new corners can be fitted in place.
To fill the corners small strips of sheet metal are cut and folded 90-degees in a sheet metal brake.
Next up the Eastwood Shrinker/Stretcher is used to shrink one edge of the custom new pieces to replicate the look of the factory corners in the newly required radiuses.
The newly fabricated pieces are carefully fit into in the trimmed out window corners.
The new window corners are tacked in place and checked again for proper placement before final welding is completed.
Once the final welding is finished the corners are shaped with a die grinder equipped with a barrel drum sanding head.
On this particular chop the decision was made to round-off the upper rear door corners rather than retain the square factory style corners.
Rather than cut the original door corners into multiple pieces, Hollywood Hot Rods prefers to create new sweeping corner from fresh sheet metal.
Repeating the earlier process, new inner door corners are made with the Eastwood Shrinker/Stretcher. Once the new door corners are in place they are welded and smoothed the same way as the window corners.
Just a few steps transformed this Mercury from a stocker to show stopper! Hit the Hollywood Hot Rods Website to see more of their work, enlist their services, or buy some sweet HHR gear!Click Here To Read Full Post...
