Exhausting manifolds...

After a certain amount of fun, I've done drawings and got a (very reasonable) quote for getting a set of steel blanks cut to fabricate a non-turbo exahust manifold.
Now all I need to do it get the drawing checked (better now than after £40 worth of laser cutting) and pay the price tag. Oh, and fabricate the rest of the manifold from steel pipe. I anticipate a fun afternoon with a pipe bender, the angle grinder and the mig set.

Anticipated outcome: 2x good manifolds. At least 1x scrap manifold. At least one burnt finger, and at least five cutting discs dead...
