in the car and it fits. it better fit! i used my own engine as the jig.

Purging the tubing ID right?
Otherwise you leave little dingleberries that can break off and kill turbos.

What did you use for a wheel in that 009 again?

purge? backup gas? what do you take me for! not bragging, but i designed weld fixtures/jigs for the aerospace industry off and on for 20 years or more (back into the high-speed hydraulic machine workholding design again).

the wheel in the 009 is a piece that i had cut at work on the laser. it was just something that i figured was a decent size and tooth count. it seems to work after i messed with it for a while and most importantly, your help. thank you by the way.

Ah, the nice welding makes sense, the comment was more a just-in-case as folks forget, should really back purge even with MIG unless you like dingleberries.

I have to practice a bit on a similar test piece to set the current and sort the welding speed or my welds look like the first example.

Collector bits from Cone Engineering or home brew?

good point about the dingleberries (some call "sugaring") as a reminder. the purge gas (backup gas) really helps with penetration and having good weld flow.

i got the collector bits from Columbia River Mandrel Bending. I bought one of their stainless header kits (1.625) and then had a to buy a few more bends later. the flanges were made by a friend on a bridgeport.

so i was showing some guys at work some of my pictures and one asked me if i was on the vw forums. i said yes and he asked if i posted. i said i do some but i don't add much. he thought i would be a "hero". haha. naw, i told him there are so many guys miles above me. he talked me into it so tomorrow i will add some pictures to my junk pile.

working on the injectors. yes, i did that all by myself

work work work. this friggin thing is warped.

Thin stuff like that is tough to fully weld unless it's clamped in a jig, it always wants to become a pretzel.
Even then its best to do a series of short, staggered welds, jumping around and letting it cool in between.

Not too bad with the synchro, will go down to 3A, but going easy I tend to get insufficient penetration.

OTOH a few good well placed "spot"welds are likely plenty strong enough if you have it well boxed.

Love the linkage BTW, I suspect it will work great.

a little more progress...

thanks, pile. you are a serious positive influence on all of this.

Hey, I'm looking for TBs that will fit under the T3 engine cover and I found one of these throttle bodies (super cheap like you said!) but it looks like one piece, so I was wondering how you set up your linkage after cutting the thing in half?

Like the exhaust, pretty sweet Squeakie!
