Steering, “but not as we know it”
DIR By: Scotty

---------------------------------------------------------
Gents, I know that I have not fully completed my first build,
but given the time it has taken me to date, AND coupled with my
age, I believe it is time to think about build No 2. The rather
unusual 1926 Panhard, “Lame de Rasoir”.
Now this is where the rubber meets the road, or more to the
point, “THE STEERING”.
Unlike any conventional car this one came with a system where
the driver actually sat through the steering wheel and my
question is, “does anyone know of any engineering company who
could replicate this”.
I will try to attach a link to the website for the car in
question but any and all contributions would be greatly
appreciated.

In anticipation,

The link should take you to a modern recreation in progress

Jim, thank you for the link. In short someone on the other side
of the pond has undertaken a “full-size build” of this baby so
it can be replicated. Now I need to find someone in the U.K. who
can advise me on the construction and engineering. Any ideas
Jim?????

The steering in the repro has a video of the action of it. It
looks like a large flywheel ring gear driving a shaft to
something unseen, I would guess a reduction angle box to the
steering arm, the ring gear must be mounted to a similar fixed
diameter ring attached to the scuttle with some system of roller
bearings at a guess. I looked at the drawings a couple of years
ago if this and the ones I saw were light on detail, looking at
the size of the original and the size of the original driver, I
discounted the idea of trying to scale anything as I would never
get into it. Love the thing to bits, a beautiful car, but gave
up trying to figure it out. Would love to see it done

On digging through drawings Scotty, the original had a novel
connection to the wheels with a 900 transfer for linear movement
behind the axle. The ring gear on the steering wheel could
possibly drive an acme thread to achieve linear motion for the
transfer...

Jim, I can but thank you for providing the, “links” and your
invaluable overview of the design.
What you have identified does pose the question, “who in the
U.K., would have the technical skills and abilities sufficient
to engineer and fabricate a safely functioning steering system”?
I do want to combine this steering within the build however
safety is paramount and I need help OR I must rethink the build.
I remain positive Jim in that there will be someone somewhere in
the U.K. who can do this, now all I have to do, with the help of
others, is find this person.
Once again thank you for your valuable input Jim.
Regards
Scotty

Charlie,
This car is truly a piece of automotive art, as the Facebook
page suggests! Built along the original lines, it would also be
an engineering 'tour de force'.
If it isn't too much of an insult to the original concept, could
I suggest a simplification that might bring it within the reach
of home workshop facilities. If you built the steering wheel
with a single vertical spoke similar to the old Citroen DS21
design and positioned that spoke at '12 o-clock', then circa 45
degrees either side of TDC would not impact on your legs and
would work with a kart steering mechanism. However, due to the
much larger diameter of the wheel, you should have considerably
more control of the steering than in a kart. A couple of Teflon
guides positioned in the lower reaches of the steering wheel
would also help.
I appreciate that this is a bit of a come down from the original
finessed engineering. However, it would allow you to focus your
energies on the rest of the build, and this is a car that is
certainly worth recreation. :)

Gents, ( Ade & Granville ). I take onboard your suggestions and
advice, which has given me a lot to think about.
Perhaps the opportunity to discuss this further will present
itself at the A.G.M. or at Stretton.
Once again, many thanks for all of your input.
Regards,
Scotty
