Post a pic up of your best welds

[lysdexia]

why are you LOLing Momus? That's a fucking nice collector with some very nice welding..

[Commotion]

Fit is fine. I just weld from the centre out which is essentially a vertical up weld with the electrode pointing down. On the next one i will try welding from the outside into the middle, which would mean that weld direction is the same as electrode direction.

No mitre setup, just paper templates printed out of the computer. Cut along lines with angle grinder and dress up with linisher.

Material is ASTM A106-B seamless pipe.

yeh its a case of whatever works for you in those places.

I finished a pair of collectors last night and tried welding the inside of the merge the other direction but it wasnt any easier. I ended up doing the second one as per the normal method and found it slightly neater. I guess it will have to do.

Commotion, nice welding. Can you give us more information/instruction on these paper templates? What program are you using to flatten the pipes?

[Commotion]

I just draft it up in solidwork. Get the layout i want, pipe size, merge angle, flange size etc. Trim the individual pipes then slit them and unfold them like a sheet metal part.

Just a couple of recent ones. Auxilliary fuel tank for an FJ Cruiser.

Man that's some nice cast to wrought welding there.

[ISL33P]

Cast aluminium to 5xxx sheetmetal

I can't find your number anywhere. I am after 2 merge collectors if you can help out

Some amazing work in here guys. I have no skillz but admire yours from afar.

Couple of pics of my builders stuff. Some more for show of course. Labour intensive by the looks of it. Both bikes he's made mostly from scratch. Not the motors of course.
Guess what motor/car is in the 1st pic and you win the Internet.

[dynoryder]

That last bike would make a wee bit of noise

I have been a bit slack lately but did manage to mount a wastegate off a turbine housing over the weekend. I also managed to machine another cast inlet down, just needs to be blasted ready for another custom inlet.

Looks good, I welded mine the other day, welds are not as nice bit are ok, I preheated it in the oven to about 250 deg

A model with a Chev head conversion?

Progress on custom inlet manifold. I have not done much aluminium lately and its shows, plus its 5mm thick so probably getting close to the limit of my machine but it should do the trick.

Looks pimp, did u think about helium? What do u pay for a g argon also?

Box doing good deals on helium/argon mix now.. Got it cranking at work now

[dlux]

Can you use helium/argon for ac and dc?

I paid 190 for my last g bottle of argon plus the 190 bottle rental a year makes it expensive learning to weld

[Commotion]

I think I'm paying around $160 for G argon.

[takai]

$134 for my last G argon.

[Mr Parts]

i pay $93 for G argon, and $42 for E argoshield

im in melb, if you want my hook up, pm me your number and i'll pass on the details. Bottle rental is $15 p/m i think?
