No fittings! Gosh darn it! Oh we'll. opened presents, ate like a piggy now I'm bored. Ready to go back into the shop to work on the liner. Plan on sneaking out through the basement soon as wife takes her nap. LOL!

  sounds like a plan. I still have famaily rounds to make. should be done around 9pm. Merry Christmas Rob.

Plan worked. Got about 3 hrs in today.
Worked on the exhaust pipes but mostly the transitions right out of the turbos. I calculated that I needed eight .40 pie slices out of the 5" to transition to 4" dia.
It was a little difficult as it was a short transition and ended on a curve. Lots of extra stresses in the stainless at the curve. Was able to sort of pull it all together with big radiator style clamp and get her tacked. Bigger news for us is that when I held it up to the turbo it cleared the dry sump pump and pulley.




Not perfect but close enough.
I can work it a little more round when I tack the 4" to it.

Rob,
When you weld stainless try using "Solar Flux" works almost as good as doing an argon back up and is a lot easier and make the weld on the inside of the tube high  quality. I have attached their web site.

What alloy are you using for the transition?

Too late Pete! I already ordered some. Probably be here tomorrow.
Thanks Rex! This will probably eliminate some of the nasty black buggers that you can get when welding the thin wall stuff.

I use nitrogen to backpurge stainless TIG and much cheaper then argon.  (only works for stainless backpurge though)  You can also use copper sheet protecting backside of weld and then use gas lens to get good welds with a bit of practice.

Rob,
Thank you for taking the time (on a work day) to show myself and my brothers the progress that you have made in a short period of time.
At this rate you should not have any problem making your August goal for Speedweek. The build is surely impressive. Keep up the good work.

Dave, thank you and your brothers very much for stopping by. I always enjoy our conversations.

This must be mental illness but I spent my New Years Eve alone at the shop working on the liner instead of whatever.

[Kevin G]

I got roped into going to a party. I would have much rather been in the shop.

If its an illness it's present in Aus too, peaceful evening welding.
