Here are photos of our jig to re-make a common sized water pipe on a Ferrari 250. We have been making flanges at the water jet shop and have a bunch of the large bell flanges that adapt the 1″ tubing to the larger thermostat housing.

This 304 stainless steel is great stuff, very workable, machinable, weldable.

Reproduction water pipe in stainless steel

Early Ferrari cars used steel tubing for the cooling system which corrodes seriously over time. Since replacement parts have never been available, these pipes were often patched together, soldered up, welded, epoxied- whatever to make them hold water. Typical of the Italians, the pipes are beautiful with gentle bends and are very difficult to recreate but we have a system to make them out of stainless steel 304 series tubing.
