If interested, let me know, and next weekend I will try to take an inventory. Would love to do some trading for a convertible back seat lower cushion (possibly a top seat back too), and/or the rear window regulators that were used on the Super convertibles.

Reverse engineering completed. One of those is laser lithography. This method uses an original piece... many times a used part, as the basis from which the process derives engineering needed to reproduce the part. Think of this process as a laser scan of all surfaces of the original part. The laser scan is a very precise measurement of the part which is converted into a 3 dimensional wire frame engineering model. That wire frame can be input to existing engineering and computer controlled manufacturing tools and interfaces.
How much does this process cost?.0 -

The following website will take you directly to an article about frame reproduction and the use of laser scanning to reverse engineer a vehicle frame. http://www.laserdesign.com/project_news/200/
I know what our costs are using an inhouse scanner. They will not be the same as a vendor scanning a customer part... these folks should be able to answer your question accurately.

Holy crap! At the suggestion of a post on another forum (http://www.jalopyjournal.com) I did a search for patents under the name of Millard Toncray, who was evidently an engineer at Hudson.
This patent has complete drawings of the Hudson stepdown frame:

Now all we need is dimensions! Just a minor detail ;-)
I haven't looked much farther but I'm sure some other cool patents will show up.0 -

The Hudson Frame measurements can be found here:

Ken- those are certainly valuable dimensions to have but not enough to build replacement frame rails.
It wouldn't surprise me to find that the patent drawings are 100% to scale. That could be checked by scaling one or two measurements and then comparing others. If that's true, much of the info needed to recreate them is right there for the taking.
