Bédélia

I am building a Bédélia, a French cyclecar (the first cyclecar
ever), which was designed in 1910, initially as a one-off, with
public demand leading to production.
Interestingly, it was quite a successful racer in its time,
despite its very odd setup. It had wire and bobbin steering
which pivots at the centre of the front axle like a plank
go-kart. I was going to change it to Ackerman to benefit from
current wisdom but then thought I ought to keep faith with the
original design. But it does worry me.
Stefan has suggested I could lean the central pivot to create
caster, which could be an exciting compromise[img][/img]

A brave build and I for one am looking forwards to seeing
progress on this. Kudos to figuring out how to put the accents
in, I struggle with that. :)

Thanks Peter. I understand that posting photos here is not
straightforward. However we are reviewing the whole website and
this matter is top consideration.

I'm glad you have reverted to the original front axle design,
don't let it worry you, fortune favours the brave.
If you build the front end with the thought that you may have to
change the layout if things don't go to plan it won't be an
irrevocable decision, i.e. allowing for retro fitting other
axle mounts etc.
But if it worked for the real one you have a good chance it will
work for you, and will make a fantastic and unique cyclekart.
Good luck with the build I look forward to seeing the build.
Peter

Thanks Peter. That is very encouraging. I have tried to build
some flexibility into the design. [img][/img]

oh dear ;) Brave is usually a euphemism for stupid :)
Thanks very much Jim
(e acute is Alt 0233 but there must be some way of creating a
single stroke macro to save me all that keying-in!)

Interesting the Pilot is behind the passenger, is that
you can't where you are going to crash!!! Joking :D
I think this is going to look great, and ironing out
the little kinks is a big part of the fun.

Hilarious arrangement, isn't it! For mine, I shall be the
"passenger", mid-car, with a mid-engine and with my legs where
the engine was on the original (which unfortunately has to be a
bit wider, as a result). Something like the picture but with
rear axle further back and with a faked up rear
driver[img][/img]

I’ve been pondering this, not sure caster works on a steering
axle, it’s probably more the jacking effect that will centre
the steering - you’ll only want a little. It’ll lean you out of
the corner too. Definitely one you should test before too much
fabrication.

What do you mean by the jacking effect?
I have been thinking that a castered central column would lead
to a twisting effect when turning, with one wheel lifting.
