1..2...3..ya, that's 6 of them:
It has been a long couple of days. About 20 hours in to these 6 manifolds, and they are about 1/2 way done. Now I need to setup the back purging station (oxygen inside the pipes displaced by argon for a clean weld on the inside) and then go to town. Each manifold will take about 1.5h to weld. Once that is done they go back in the jig, and the last couple of pieces get welded, so the header flanges can be attached. After that, the waste gate tubes and O2 sensor bungs. I plan on doing one per day next week. There is 24 welds per manifold, plus 2 O2 sensor bungs...so it's a bit of work still left to do.
In the mean time, tomorrow will be spend working on the recirc tubes, and hopefully I have time to weld up a down pipe or two. See how things go I guess.
Also, still have one kit without a name on it.
