You are the fucking man.

I love your work.

cures for ED

My version of seans bead roller. Timed myself, took less than 7 minutes to make this (which included digging the welder out of my parts pile and finding my shit set of vice grips) haha:

Here is my first attempt at MIG welding. Aluminum is a completely different beast, hats off to you folk that can lay down dimes. It took me four hours to make 16 small welds.

Initial results were....suboptimal

Last weld of the day, slightly less shitty.

In my quest to just get the goddamn aluminum to stick together, I neglected to tack everything up first, then proceeded to put a ton of heat into the welds. You can see the frames are warped by about an inch at the top.

So I ended up adjusting the cedar planking to compensate. Not really noticeable from the outside.

Any ideas on how I can the the aluminum to look rusty like the steel? Paint seems to be the only option I've seen so far.

There's two things you don't usually see together - MIG welding and Aluminum.

Not true at all.

My last job at the fab shop we did it all the time. Way more than using the tig.
At my current job the boys in the fab shop ONLY use mig for aluminum...

It's pretty common.

I'll 2nd that. We use mig for aluminum primarily, at work. I'm about the only one who uses the tig, and is only for learning. We have yet to use it for a job lol.

its common and has the traits of mig welding. its not as precise and not as clean.... but its much much faster when compared to TIG welding.

its used in a lot of process type stuff- some MIG welders are pretty trick now... more than your basic on/off welders.

did you use a tri-mix gas?

Buddy of mine does aluminum repair for sailboats, I was borrowing his welder and bottle. I have no idea what was in there.

Dual flow meter arrived today so I can finally back purge stuff.

A transition I did for a friends R33 gtr for a 4" mid pipe. Port guys damaged the Apexi mid pipe taking it off the boat, it connects a Nismo cow pipe to the 95mm part of the Apexi exhaust

Lunch time G-job, V-band back purge cap/heat sink

Fuck I wish I was that baller.

That is a little bit more fancy then the v-band heat sinks I use when building my setups. I still need to find a way to put in a way to test pressure.

I'm getting creative with an old turbo I bought from you Lars. Lets see how quickly it does(n't) spool with 2.5l.

At lunch I'll see if I can attach some unknown, probably leaded, mild steel to cast iron.

Rumor has it that Treadstone will do this to just about any turbo they sell if you ask them nicely.

Given your skills you should be fine.

You left out the third v-band off the turbine near the flange for dual EWGs!

Swapping springs in one EWG is enough.

So it took a little while to choose a filler rod. I ended up using 309, with ~45min @500F preheat and shutting off the oven and letting it cool itself done post heat. So far there's no cracks. There's some silicon bronze and a few other material tacks mixed in there.

So here's a chinese "EMUSA GT28" turbo direct swap for a Precision vband turbine. hehe

<p>Mucho sexy. I need to do that to my next turbo.</p>
