BUILD-OFF CHALLENGE: Tygaboy's '75 LS3, It seemed a good idea at the time... Options

[tygaboy]

Reservoir in place. I like the way it turned out.

See you been spying on my thread again (IMG:style_emoticons/default/shades.gif) I like the mount why did you choose that location? I am just wondering, as I put mine closer to the stock area, so the over filled fluid can run done the fresh paint and start the 914 conversion to rust process all over again. (IMG:style_emoticons/default/huh.gif)

(IMG:style_emoticons/default/poke.gif) Start working on the solid roof section (IMG:style_emoticons/default/poke.gif) I have my ideas in my head as to how to do it, just would prefer you to burn the stack of metal that comes from doing the work 3-6 times to get it just right. (IMG:style_emoticons/default/aktion035.gif)

Stephen - I located it there because the chassis stiffening bars I ran to the front shock towers sort of prevent me using the space where the stock reservoir lived.
The roof will likely not start to happen until after I have it on the road. I want to focus on getting it running.

Next, it was time to make a panel to close off where the late model cars mount the fuel pump. I'll use this as the passage for the reservoir hoses to the pedal assembly.

I started off by cutting a simple panel with the appropriate holes for the hoses.

A few grommets and I'm done...

[tygaboy]

That looked OK but I figured I could do better so decided to make a die for the press that would allow me to raise the section around the hose holes.

I plasma cut a couple pieces of 10 ga and marked them so I could align everything once it was all in the press.

[tygaboy]

Into the press and out comes a tidy little part!
And yes, I installed the grommets AFTER pressing... (IMG:style_emoticons/default/poke.gif)

[tygaboy]

A couple more items checked off the to-do list.

Chris a question for you, are you clamping the sheet before pressing like you would if you where hammer forming? Just wondering how your get a nice finished part. Or is it a bit rough and the run it through a planning hammer or lots of hammer and dolly work. Wheel them, just wondering wanting to learn a bit.

Stephen - I measure and mark the panel so I know how to position it over the "open" lower die. Then I set that "insert" piece on top of the panel, doing my best to align those cross marks, and then press it, forcing that insert down into the panel, creating the raised section. The press does all the stretching and flattens the part all at the same time. No secondary operations needed.

I figured someone might be interested so... here's the video of the part being made.

And @Andyrew , there's a good look at the press you were asking about.

[Andyrew]

Nice! I remember that being there. It's able to do anlog more than I thought it would!!

[tygaboy]

Sharpie transfer punch, a few holes, find some suitable screws and it's all done.

[tygaboy]

Then moved on to making a new plate to mount the in-tank fuel pump. This will get welded to the tank in place of the filler, which will be relocated.
Using the plasma table really does feel like cheating.

[tygaboy]

It'll go about here. I'll be ordering a new tank, too.

Nice Chris-

If using a plasma table makes you a feel like a cheater, I'm like Kent. A repeat offender relying on some of my shop talent when pressed. Your creativity is mind blowing. Love this thread.

Oscar -
You are too kind... Thanks for the generous compliment.

[tygaboy]

More panel fab. This time, its the piece that'll serve as the front bulkhead for the fuel lines.
I'm figuring out better processes for pressing the raised sections:
I cut the female piece sized exactly the same as the panel. Then I just sharpied where the male piece needs to sit. Much simpler to set up and virtually guarantees a great result.

[tygaboy]

PRESS and...
Presto! (see what I did there? (IMG:style_emoticons/default/laugh.gif) )

Turned out nicely.

[tygaboy]

Next, it's time to fit the fittings to see how they fit. Hoping they won't give me fits.... wait, what?

[tygaboy]

Just set in place to see what's what. The panel will sit a bit higher once it's bolted in, but you get the idea.

[tygaboy]

And the tank side. It'll be soft lines from here up to the pump. One supply, one return.

[914forme]

Okay I got it, the picture left out one detail, the upper upper die, or that flat piece that sets onto of the 10ga plate that presses down.

I like the setup here, and the bulk head for the fuel lines. Same general setup going inlace at the back of the cabin?

And if you think a plasma table is cheating then keep right on doing it, as the end product is worth the "cheat".

[tygaboy]

"Tunnel Vision"

The stiffening plate at the front is 10 ga - thick enough to support threads. So a quick mark/drill/tap and the bulkhead is finished.
