The fabrication thread.

Here is a thread I am starting to showcase the fellow fabricators here on the forum. Post up your legitimate fabrication projects.

rules:
No lame projects (weld on muffler, bolt in cage, silvia fronts, stupid stuff)
Be informative to help others with their projects.
Showcase the production process (before, during, after)
Constructive critisism only.

I will post up some more interesting things once i get my camera from work and upload the images. I will post pics of some aluminum valve covers I made for a gt40, chassis modifications, roll cage fabrication and DIY help tips, welding pics and tips, custom 2-1/4'' headers I am making for the shop car, a 500 ci donovan fuel injected supercharged aluminum big block
(yes a real donovan)


If anyone has any questions for fab projects feel free to pm me if you think I can help out in anyway. Thanks.

Project: 69 Camaro pro touring.

mock up: (old iron block no blower)


Willwoods all around.


Forgeline wheels.


Custom air ride rear suspension. fabricated to hold coilovers.


Yes that is a quick change on a street car.




Custom fabbed t304 stainless gas tank. All tig welded.


Custom subframe.


Custom made subframe connectors. Now tig welded.


I will post up action shots tomorrow.

Those big chrome gills right in front of your rear wheel that serve NO purpose. Can't you remove them and weld up the holes, that would be some good fabrication.

Sorry the rear wheel vents are a trademark of the camaro, and eventhough the production can vents are only visual in purpose, they were added so that the factory team could use a functional piece. They are original and will stay in place. Besides.. I would not consider plugging some holes with a mig and sanding some bondo "fabrication".

Huh? It's a ford 9" with a billet pinion support.. I am new to imports, but i've been around domestics a long time.. This is a quick change.. It's called a quick change because you can change the final drive ratio in about 5 minutes by taking that rear cover off and changing two little gears, but the ring and pinion stay the same..

that is true. Alot of circle track guys use those rear ends. I will double check the specs on our rear end tomorrow and let you know exactly what it is. From what I was told it was a quick change of some sorts.

I forsee this being a great thread. I think the thread rules should also state that it has to be the poster's fabrication. It shouldn't be some fab work that you happened to see on some random google search. This way real answers to questions about the fab work could be given. +1 to the op for a great thread idea.

Awesome thread! I am going to document the front diffuser, radiator duct, and brake/intake ducts that I am going to fab up for my front bumper. I'll be back soon!

Well I guess I could post up a turbo manifold I've helped built. This was on my car, then all of my turbo stuff got stolen , But anyway onto pictures. Here we are mocking up the turbo position.





Here it is with runners and all welded up.



Here's it is completely done w/ IC pipes and such

I don't have any pictures of any thing recent, i never remember to photograph my work. I just bought a nice camera so i will be now. I also haven't had the chance to build anything cool in a while.

Here is a set of Turbo Headers i built for a 347 powered Ford SuperCoupe, the original headers had been repaired multiple times and finally blew apart, they were also 1.5" tubing, and we stepped up to 1-5/8ths. This car made over 630Hp.
on a Fixture i threw together real fast, i made these headers from start to finish in a couple of hours.

old vs. New

Finished pair, the wastegate was located on the Crossover pipe Which the customer made himself at his house.


The first Intake manifold i had ever made bout three or four years ago, it was a employee of mine, he wanted somthing simple.


My car. This thing has been sitting collecting dust for two years, and has only ran for a week since i built this setup in 06.


Evo 8 Turbo with under 1K on it.


Fully wired up, and ready to run, but it hasnt in almost a year...


Thats it. I wish i had more to share. I have improved alot since alot of these were taken, It sucks i Havent been recording any of my work.

Jon

Great replies everyone.

slw240sx: Mad props on the fab skills. Making both of those in one day is awesome. Can you share with the viewers some tips on minimizing production time, and some tips on getting everything done on schedule. Such as collector placement, runner length, overall expectations for the project?

Sweet.

burnsauto: yes. Inovative placement since the usual location was not available.

Nisils14: Awesome angle on those beautiful collectors. Flow is shaking your hand with that setup. lol

Also great manifold design assuming it was thick material.

What gauge did you use?

Again. Great to see some contributions. Any pics before, after, during, to help the DIY guys ?


mods.. Sticky please

Drtyrat: I agree. Only personal work. Dont post up a pic of a F1 engine and say it is awesome.... we already know it is.

So... yea. Only cool fab stuff that pertains to you.

racepar1: I would really like to see your documented build of that.

Gimme a week or two as I need to repair the cracks in the bumper first, but I promise I will write it up and take my time so I have a good product at the end not some piece of crap.

schedule 10 is cool. I assumed it was 304

Is there anything you can give out for info to help the DIY or newbies?
Let us know what you did to figure out the runner length, collector placement, etc. lets spread it out.

No hurry. I would just like to see it. Also please show what little tricks you use.

Me personally I would try to show any tricks i use. Such as using a radius gauge set, contour guages, hell even a protractor. anything to make this thread useful in a way that is beyond visually attractive.

Luke you've nailed it on the head, there needs to be more informative posts on zilvia, and this is a step in the right direction.

love this thread idea..this is coming from someone who will be getting into fab very soon.

might i add that perhaps some details on what techniques were used to fab. ie, what equipment was used to bend tubing, what was used for mockups, what type of welding, what equipment was used for welding, etc..

just a though for us fab wannabes.

+1 for unique thread idea.

This is the only parts i have really made on my own other then bracket for holding the IC and a cart for parts:

S13 Hatch Harness Bar Version 1. Cost me $25-$35 to make using Steel from various places.





I have since changed it, and added pieces that go off the cross bar that for where the harnesses bolt to. And Things off the back that have 1/4 steel bars that go down and bolt to where the rear seat belts bolted to. I will take new pics later.

I also made some custom reinforcement for my clearanced S13 bumper stupport using 1 1/2 inch angle iron.

This would be awesome if you could make a vertical stabilizer that would go down to where the seatbelt bolts in under the door.

Great idea blu808, that camaro looks amazing, awsome fab work.

Heres my first project I decided to tackle last year when I was 16, my first time welding/fabricating. Its nothing compared to the other projects but I figured I'd contribute to get this thread going.




It is bolted to the floor, I know not a good spot but there was no other easy solution. I'll be taking it out to paint it soon, when I do I'm going to re-inforce the floor mounting point, redo some welds and maybe extend the uprights around further. The sheet steel is 11 gauge, and the tubing is 1", 0.095" wall steel, $30 for all the metal.

Thanks for the comments guys.

KA_T; Nice harness bar. Looks well though out and finished. Im glad you put some down tubes on it.

sidewayz240: That is a cool strut tower bar. I like the brackets you made to hold the cross bars. Im assuming that was mig welded?

A triangle is stronger than a straight piece.

If you look at most roll cage designs they are mostly all comprised of triangles.
