Seems a good fit. I'll find out another time how well it holds up to the torque.

You can't really going to 3 angle your valve seats are you Rob?

Bingo Graham, three out of three.
I don't need a fancy cutter as I'm only doing the job once, so grinding paste will be fine.
I cut this edge to 30 degrees.

Seems to fit. I'll know for sure once I start cutting.

When he retired from cabinet making, my granddad owned a hardware store. I was too young to remember it, but I think it was one of those places with ladders, no room to move, and shelves upon shelves, where you could find absolutely anything. I think my garage has the same kind of ethos.

Next tool... 9mm carbon steel rod.
Reduced down to 8.97mm.
Marked about 50mm from the end. Too easy this one.

Slide the sleeve up to the black mark.
Weld through the holes and around the one shoulder.
And it's important to get the outside nice and smooth and back below 12mm.
