tooter's manifold adventure...

[CrankyOldMan]

OK, I got it to cooperate long enough to get something banged out. Here's the problem I was anticipating with the overhang:


The left hole is OK to machine from one side. It's not really possible to mill this shape on the right without a 5-axis mill, tilting the flange after milling the inset groove, or flipping the part over in the middle of machining that opening--none of which is possible/practical for me.

*edit*
One alternative I've thought of would be to bore the head side hole straight through on the left edge and backfill the difference when welding and die grind the bore smooth.
