Teaser questions:

1. What's wrong with this picture?
- Hint the LS3 operates with a DBW throttle body. That there is a mechanical linkage.

Answer: Nothing is wrong with the pic.

2. What silliness have I committed myself to now?

Answer: I'll post pics as soon as I can! (IMG:style_emoticons/default/stirthepot.gif) (IMG:style_emoticons/default/happy11.gif)

Well, it's finally happened. I'd been doing well on the "nothing I've welded in has had to be cut out" front but the work sunk into the fire wall openings for the initial main hoop design has been cut out. And it's going back to exactly what it was before I started messing with it.
Ah well, it is what it is... (IMG:style_emoticons/default/sawzall-smiley.gif)

Turns out I had kept the driver side piece from the '72 I parted out. I still have a few tweaks before I'll call it done but it's turning out pretty well. I'm (IMG:style_emoticons/default/smile.gif) !

Now to source the passenger side piece. Sounds like Cary has a nice one...

It was a day of metal work. First the firewall then back to work on the chassis stiffening.
I decided not to do the gussets as the primary tie-in for the front hoop. Instead, it'll be a bar from the hoop to the front suspension tower.
So I thought I'd take a swing at fabbing up a support pad.
The big compound curve means I got to practice with the English Wheel and shrinker.
It still needs some additional work and final trimming but I think I like it!

Thank you, sir! I'm leaning toward doing a tinted bed liner on the entire underside of the chassis and both sides of the firewall. I suspect once that coating goes on, any evidence of the repair will totally disappear. Hope so, anyway.

English wheels are fun!!! Thats a small panel to be working though... Be careful with your fingers...

Took a bit of work to get the piece you need. Its jacked up on Super In Laws wooden stacker. So we got the Big Joe pallet stacker out and lifted it off the contraption.

Down on to Doug's wooden dolly and ready for amputation.

Part was extracted by Super In Law. Pretty simple until you get to the air vent hole. It has 3-4 layers going 3-4 different directions. Took him a couple hours to figure it out. But he got it out for you with the flanges intact.

Part left with Matt. It will get shipped out at 914 Rubber.

After that he kept tearing down the parts car. Not keeping too much. Cut out the remaining portion of the firewall. Probably the headlight buckets. Longs are crap, but we'll cut out the uppers and the mounts. We'll cut out the tunnel and see what we have. Door hinge posts. Front portion of engine the engine tray. He busted his ass all day ..
Still amazes me ..........

Much as I love Martin's help doing the TIG welding - and plan to have him do more - I happily admit it pisses me off and is a personal sore point. I will never hide this fact and whenever anyone comments "wow, nice welding", I have to give credit where it's due and I tell them about Martin.

It's... I'll say "disappointing", because I'll never be able to say I did 100% of my build. It's just how I'm wired.

So what to do? How about practice?

As some of you may know, I have a little side business doing yard art sorts of stuff and that affords me some work where my welding structural and visual results aren't quite as critical. Not that I don't do the best I can...

Anyway, here's part of yesterday's MIG work, as welded, not cleaned up. It's part of a 12' wide, 7' tall, vertical xylophone I was commissioned to do for a local school.

The "out of position" work is where I'm not reliably up to snuff. But I'm SLOWLY getting to where I may feel comfortable doing my own welding on some of the more visual areas of my build.

Dem some nice C's! Penetration looks great as well!

Can you turn up your welder any more? I would have preferred a hair more heat myself so long as the metal can take it. (My only critique, Your technique looks spot on!)

Chris, top notch as usual. You reshape metal quicker than I can turn the welder on!
Looks great.
Cheers

Thanks Andrew - Yep, I have lots more headroom in the welder and I was thinking that same thing when I examined the HAZ. Coulda been a little hotter.

Hey Dion! Not so sure about the "...as usual" part. More like "sporadic flashes of competence!" But I am gaining some consistency. (IMG:style_emoticons/default/welder.gif)
It's funny how I "know" what to do but things seems to get a little blurred as they moves from my brain to my hands...!

Big thanks to Cary, Super In-Law and 914 Rubber! The firewall patch showed up yesterday! (IMG:style_emoticons/default/aktion035.gif)
I had planned a day off to work on the car so in it went.
Here it is all trimmed up, ready for welding.

Hit it with some weld through primer (I found a few pin holes I need to close up...) but I wanted to get it at least some protection.
By the time it gets the final finish, I think it'll look "factory fresh". Hope so, anyway.

(IMG:style_emoticons/default/pray.gif) Dangit! You aren't helping me feel satisfied with the patch I just did in that same spot. Nicely done. But you know... I REALLY could have used that firewall patch a couple days ago. (IMG:style_emoticons/default/poke.gif)
