Default Frazer-Nash BMW wings.

Here is one of the projects that I am working on at the moment.

I have to recreate the wings of a BMW Frazer-nash. I will use the original wings a buck as it would be far too costly to make a buck. the wings are very complex.

The first thing I do with a job like this is check the wings match each other, invariably they don't. Often when repairs have been carried out the shape can be changed from what it should be. It is then a case of doing the best I can to ascertain the correct shape from what is left. I am not sure if the wings are actually a matching pair,they were considerably different in some dimensions. I do not have the car here to work to so after talking to the customer it was decided to make a matching pair rather than copy the wings.

To this end I added a few pieces and adjusted the wings a little to make them more alike.



Many carefull measurements were taken and comparisons were made between the wings so that I could make new wings as a matching pair and as like the original wings as possible from the information I have.



Paper patterns were taken so that I could reproduce the side peices of the wings. The steel sections were then formed using my P21 Pullmax and a shrinker stretcher. I try not to shrink or stretch too far into a panel with these as I dont like to mark the metal more than need be.



I made tooling for the pullmax from plastic which gave me the swage from there it was a mater of manipulating the panel to fit the original shape.



the side was formed from two pieces.

More soon.

You are not alone ....

The skill to imagine and make conclusion´s, how to make a original looking fender, from something that has parts missing, is something I really admire.I also think it is a important skill..so I will be spying this..

Cheers guys. Janne, to work or what is the correct shape from a pair of wings I will look for any repairs, if one wing has a repair in one area and the other does not I check the shape of the repaired part either by direct comparison if possible or by making profiles. If there is a repair that is obviously pulling the panel out of shape I will often cut the repair out and reshape the wing to a point where it is as close as possible to the right shape. I sometimes weld in simple sections to give me something to go by and to give some strength back to areas that have had bad repairs cut out.

Hi Chad, I have not done much to them since you saw them, I have been busy on other things. I will finish them soon though.

Thanks everyone for your interest.

To ensure I end up with two wings that are a matching pair I make paper patterns then cut my blanks the same, whatever I do to one I do to the other so all the sections that go into a panel like these wings will end up the same.





I used the same tooling for all the swage details I just addapted the way I used it. I will post a photo of the tooling soon but its pretty much a cut profile of the swage.

For each section I made a paper pattern and cut it out along with the same part for the other side. I then wheeled the sections to shape...



By making the panels in managable sections I can ensure that the new wings are very close to the dimensions of the originals by ensureing that each section fits acurately to the existing wing or buck or whatever I am using. Its one thing to make something abstract but if it has to fit a vehicle it has to be a accurate as possible, especially if I am supplying the panels to someone else to fit and not fitting them myself.

I wheeled several sections to make up the outer part of the wing....





The line that runs down the middle of the wing was marked onto the new panel sections then indented on the wheel.



More soon.
