I'm looking for an intact 156" wheelbase 1951-1954 Henney-Packard Tail Pipe for use as a template. I have the factory blueprint but no one has been able to make the pipe from it due to one large radius and even some compound radii. I've contacted antique auto exhaust specialists, modern exhaust companies and even commercial and aerospace pipe benders and only one would even give a quote which far exceeded the value of my very rough car. Does anyone have a parts car which still has an original in good enough condition to use as a sample for making a new one? These are not just longer versions of the passenger car pipes and are completely different.
Good Morning Don...It seems to me that many electrical companies bend conduit at least as big and bigger than our tail pipes, for major electrical installations. One in your area might well be willing to have a go at it. A good conduit bender might take you on as a side job. Perhaps an in person visit in your area. Those guys are used to blue prints and all sorts of strange angles. Just trying to think out of the box...Ernie in Arizona
Hi Ernie, The problem with it for most commercial places is the diameter and wall thickness. They said that smaller pipes are no problem but on a 2” diameter pipe with .050” wall, the machines would simply crush it and few could do the specified large radius in front of the rear axle. One place in Western Oregon said they could do it if a wall thickness of .200” would work! I have a list of several dozen places and those that replied at all told me the same thing other than one aerospace place which quoted many thousands of dollars.
