They moved from northern Paris near St. Ouen across the Seine river to cheaper space north of La Defense in the suburbs.
Bill. It's an interesting machine. Do I understand correctly that this machine will make the first sheet metal adaptation - deep deflection? Allows shape curves. Horizontally to the left and to the right?

Some time ago I bought a powerful bead roller. They gave me two pulleys with like simmilar them Olive. The machine has a fault and I did not have time repare with it. I want try it. Maybe did only the gutter drains for houses on the machine. Something like that I see that do boys do on Olive.

Thanks Bill. Very interesting article on a beautiful car. Especially enjoyed the section on lacquers employed in finishing.

Fascinated with the olive machine too. Not certain I fully understand its use other than rolling in shape sans shrink or stretch?

Bill,

Thanks for the link, great reading.

Is this an extract from the limited edition published on Saoutchik a couple of years ago? I saw it and was tempted but couldn't justify the cost. If this is an example of what was in it I'm regretting my decision....

An "olive machine" curves a sheet of metal, but does not stretch it the way an English wheel does. You can achieve the same result in an English wheel if you use a soft upper wheel, such as a go-kart tire.


The French carrosseries used olive machines to get a quick curve in a fender or a roof line, and then used a martinet for actual stretching and shaping.


That has been Mohamed's technique to this day. Ben van Berlo's Mechammer II and Mechbammer are developments of the French martinet, which is a pneumatic power hammer. I believe martinets were more controllable (and safer) than the Italian maglios (small trip hammers), or the northern European version of maglios called helve hammers.

Bill. Thank you for the explanation. I thought it right. Olive is for the first coarse bend. Completing the shape is a matter of another art.
I still think about this technology. The basic question. It will make it easier or harder for work. If I work exactly from the size of the model.

When will be the machine is set up and in action, could you make a small video in action for an information? It's interesting and unusual.

Yes Jaroslav. The next time I visit Mohamed at his new shop/school in Tunisia I'll make a video. When he worked for Cooper in Lyon photography wasn't permitted.

Yes, when photographing, it is necessary to honor the wish of the owner who shows you with confidence and his technological consciousness. In today's of more schizophrenia world.
In one workshop about 12 years ago, they showed me the fundamentals of sheet metal shaping. They showed me everything I asked. Only just what I asked. I was there for about 2 hours. It ended with a statement - if you are stupid and manual stupid, you cannot never use this information.

The more I am aware of the shaping, the more I realize the true of the sentence.
It is very difficult to pass on knowledge. It is very hard to find someone who wants to develop them. How many years need for geting information. How long it will be possible to use information and combine it with practical experience. How will long time he can work than his body forbids him it.
When he returns his efforts.
These are terrible questions. No pessimism, but reality.

Passing consciousness is a duty !!!

I look forward to will see and hearing about this interesting technology.

However, Mohamed has told me he recently located a third one and is having it shipped to his new shop in Tunisia.


Again, great article with lots of useful photos.

Hi,

Last weekend, I heard a rumor of a fourth Olive machine, here in Milwaukee Wisconsin. I'm trying to follow up on the rumor, it seems to be a bit out of place here in Wisconsin, but stranger things have happened.

Will let you know what I find.

Bill
