The surface grinder at Gary's shop did wonders for the manifold
With the other side flat it could be held to properly address this side
A good flat surface and clean threads once again
I ground off the old welding and Gary cleaned up the inside on the mill
Ready for service again
Original manuals show the exhaust pipe crimp
What an original Nelson crimp looks like
With a fixture set to hold the same end dimensions the crimp is pressed
Some early attempts
It looks and sounds as it should, the crimped end really cuts down on the harsh sounds
The old dump rake hasn't seen action in many years now
