2017.01.26 - UPDATE! - MORE TANK PARTS INSTALLED...
Rolling....!!
Just to clarify a bit more, here's how that tank "kickout" looks when installed under the rear framerail...
You can see that the entire profile is supported against the underside of the framerail, even as it gently sweeps upward toward the rear axle. It also allows for a very simple vertical strap to connect from the sides of the tank up to the framerail to hold everything in place.
The next step was to render those kickouts in 304SS. As usual, the first one took some time.... (it WAS made easier with the new wiring of the 20" grinder since I could easily start and grind whenever I wanted without blowing the 20A breaker!) and the second one was traced from the 1st so it went very fast.
Since the tank has a slight taper across the bottom (5*), the sidewalls of the tank are NOT at 90-degrees to the bottom. The rear is actually a 95* angle, and the forward 14"x12.5" plate needs to be at 85*. I put about 10 tacks on the rear plate and it was strong enough to gently "persuade" to the proper angle without breaking the tacks.
When the tank is actually set on the bench with some angled blocking underneath it, you can get a more accurate feel for how it will look when it's installed in the truck. Remember: The whole reason for the 5* taper is to follow the factory taper of the rear bedsides (between the fenderwell and the bumper). This keeps the tank 100% invisible when looking at the truck in a side-profile. Even the factory 20-gallon tank would "peek" out from under the rear fenders and it always looked a bit odd..... and of course, that's an area where you want to maximize ground clearance as much as possible!
That just about wrapped up the night. It might seem a bit slow, but I'm actually encouraged by the progress since stainless is quite a bit harder to cut and edge-finish than mild-steel.... so it's a bit of a learning process. It's only been two nights of moderate fabrication work, but already the new WEN air filtration system is making a huge difference in air quality. Take a look at this filter.....it was pure white just a few days ago!!!!
My lungs are happier already.
