Well I managed to get a little in today

got the cat sitting where I want first go, so that's all sweet but fuck the angle on the plumb back for the wastegate was deceptive

took me ages to get it right. It's not perfect but the gap around it's small enough for me to fill. Almost out of gas on the welder and need to get a couple more drill bits from work so I can chain drill out the hole in the dump for the wastegate plum back. Here's how it's sitting now.
