Thought we'd start a thread realating to the past and current fabrication work we are doing in our sydney workshop.

First up a few previous and very current cages which we've done.

A couple of S chassis both half and full









A few R32/33 chassis with fairly extensive cages



















A lotus and Focus RS





Our Regular Fabrication work

180SX alloy door trims, folded over the edges.



Ford F350 alloy washer bottle



Custom alloy surge tank









We have a few interesting projects underway currently.

An on going development FG F6 ute with carbon 4 link suspension

Nice work Brad....I thought I spotted those carbon link bars when I was in the shop the other day. And I'm liking the CNC'd brackets/mounts

[turboedsloth]

Amazing work you guys are doing

[ISL33P]

ps - is that a tailshaft loop I spotted in the white car? photos 8 & 9.......that's a nice touch

[Risking]

Did you seen the skyline arms in the box opposite the ford stuff Ariel??

That's the gear everyone wants to see

I'll be putting photos of them out there soon.

That cage is in neil's R33 GTsT. The lower horizontal bars have harness lugs and the tunnel bar is there to provide some strength to the trans tunnel over the "bridge" I've seen heaps of people do those lower harness bars and the inner plates just tear off the tunnel in an accident. (so theyshould when the tunnel is .8mm tin can....)

As you can imagine there is some work involved getting a

360deg weld around those floor bars and even more to get a weld around some of the intricate X section roof bars.

[ISL33P]

Nah I didn't.....dam it!! LOL

So does that horizontal bar just above the floor go through the tunnel?

[wht510]

Quality looking work.

[Risking]

In that cage no it's welded to plates on each side of the trans tunnel. The cage wasn't aloud to penetrate the cabin area for the intended category.

Other cages I've done have that same bar passing through the tunnel and making a complete tailshaft loop like your thinking. I'll post up some photos of the underside of said car latter.

I don't think I've seen anyone else doing it like that.

[ISL33P]

totally understood!!

[DVS JEZ]

Love ur work as always. Very professional

[femno]

Awesome ally welds.

Would love some tips on how to get such a nice finish. Ive just spent a whole day trying to work out why my tig wont weld ally properly, and I have thus found out how much stainless f**ks (read: contaminates) everything up.....

[Risking]

Hey mate, good to see your having a go.

Being clean is the biggest thing.

Everything relates back to clean, technique comes after that.

If using a guillotine make sure the cut is 2/3rds knife 1/3rd snap. That actually makes a massive difference.

If using a bandsaw/jigsaw make sure it's a dedicated alloy blade.

Dont use a grinding wheel, abrasive will always get bedded into the alloy.

If using a linisher make sure it's a dedicated alloy belt.

Grinding tungstens use a dedicated grinding stone.

Make sure fillers are cleaned, clean gloves, clean bench top etc etc.

Wipe the job down with thinners, alcohol or some type of oil less cleaner before welding.

There is heaps of small things we do every job that are second nature. The process is fairly involved when I think about it in broken down terms

[wht510]

Also make sure the polarity for the TIG is correct. Consult your documentation to make sure you are using AC and DC where appropriate.

[femno]

Yes of course AC/DC where appropriate otherwise you wont get anywhere, i already learnt that

Yeah thats the thing, its second nature for experienced welders, but if youre self taught and dont have anybody letting you know these little bits n pieces it gets really frustrating sometimes.

I solved my contamination problems yesterday by trying a new belt...cleaning the tungstens and even the ceramic. I also wore so rubber gloves (dont have any other leather ones atm) to stop anything else getting on the ally. I also cleaned the filler rods for the first time (never thought of doing this before) and alot of metal dust n crap came off them!

I didnt know about the grinding wheel thing, thats good, not that theyre very useful for ally anyway.

Another thing is tip profile, some use it sharp and others blunt? My problems have been relating to the arc wondering around everywhere and struggling to keep a pool. Havent tried blunt yet.

Looks like you have been busy Brad

Good stuff

[Risking]

Tungsten depends on the machine.

One of my machines is really hard on the smaller 1.6mm ones. Regardless of balance it turns them into a ball fairly quickly.

My other machine is a gem. It can look after the tungsten and keep it reasonably consistent. arc stability comes down to the machine as much as the tungsten.

Is it a big 3phase welder or a smaller single phase job?

Thanks Andrew.

I've been really busy with various projects these are just a few of the minor fab jobs that have been done.

Tony from Wakefield park just dropped off his new Honda integra which is to be started shortly.

Cage, and safety fit out.

[zebra]

Same model Integra as the other ones?

Also, have you done any cages and/or suspension work to 70 Series Supra's?

If not, I have a nice cutaway drawing of a works group A version I would like replicated next year sometime

Latter model than the trackschool cars.

There really isn't much demand for supra stuff so I haven't bothered. I've done a couple of jza80's and a set of custom arms for one but nothing earlier.

[zebra]

Yeah no worries, I'll send you a pm in a min with the pics and see what you think
