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...
I must admit that when it comes to my projects I have A.D.D, especially one as large as Pile House. Sometimes life gets in the way or we have other projects going at Eastwood (like our Project Resolution Mustang), that I can only devote small amounts of time or maybe a day here and there on the truck. When that's the case, it's tough to start or finish projects that take a big chunk of time to accomplish. One of MY resolutions for this year is to finish all the half-done and partially finished projects on Pile House.
One project I had started a while ago was the custom front bumper build for the truck. I did what many hotrodders have done throughout the years, and hit the junkyard to find a suitable part to modify and retrofit to my truck. The result was a bumper bar that looked close to original.
Since then I've done a lot to the truck and the bumper has sat under a layer of dust in the bed. The other day I had a spare afternoon to tackle the rest of the bumper project. The biggest task left was how I was going to mount the bumper to the truck. With it being winter here I decided to opt out of another junkyard trip (removing rusty bumper brackets in the snow is NOT my idea of fun). Instead, I took some flat steel and made up a set of mounts. These mounts needed to be strong enough to help support the weight of the front end of the truck when I lowered the airbags down. I didn't want the sheet metal taking the weight every time I aired the truck out, especially if someday the truck will have nice paint on it!
So I started by cutting some 5/16" steel plate to length. I planned to make a triangulated mount that would help hold the weight when transferred across the front bumper.
The first piece we needed to make was an "L" shape out of the flat bar stock. In order to get a nice bend in this I used the oxy-acetylene torch to heat up where I wanted the bend, then I used some leverage with some pipe to make the 90 degree bend I needed in the bar. The key is to get the metal "cherry red" hot where you want the metal to bend. With the bends made in the bars, I cut some more 5/16" plate and triangulated and braced the pieces I bent. This will add rigidity to the bracket. In order to get a better fit-up of the cross brace, I sanded an angle into the ends of the brace with the Belt/Disc Sander and finally tack welded it together with the MIG 175 welder.
With the bracket starting to take the basic shape I wanted, I cut another piece of 5/16" flat bar that I could weld to the backside of the bumper and the bracket. In the end I want to shave the bumper and have no visible mounting holes, so the bracket must be welded to the bumper bar itself.
Finally, I test fit the bumper and drilled my mounting holes to attach the bumper to the S10 chassis under the body. Once I was happy with the fitment of the bumper, I took it off and finished welding all of the seams on the brackets and the bumper bar with the MIG 175. I then decided to add some additional bracing to the bracket to help combat any bending or flexing of the bracket when the bumper is laid on the ground.
This left me with a bumper bracket that resembled a jungle gym and I wanted to box it all in so it looked a little more "finished". I decided to take some 18 gauge steel and cut pieces to the shape of the sides of the brackets. Since I was covering the inside of the bracket, I decided to seal up the soon-to-be-hidden areas with some Gray Self Etching Primer. From there I used the Eastwood TIG 200 DC to weld the panels on. Once all of the seams were welded I blended them all together with a flap disc
Now that the bumper is mounted it really makes the front end look more complete AND I'm not lowering the truck down on the front sheet metal anymore. When it comes time to disassemble for paint I'll blast the inside of the bumper with some rust encapsulator and chassis black to keep them corrosion-free for the life of the truck. With that old project finished, I can now move on to all the other loose ends I have on the truck!Click Here To Read Full Post...
