Frazer Nash Norris Special
By: Mark Under Date: October 31, 2020, 1:42 pm

Thanks for the advice, I think choosing a car to model the build
on could be difficult.
Just checked out some of the cars suggested and found a Frazier
Nash that looks interesting.
Front axle and suspension would be an interesting challenge!

That would make a great cyclekart and would be a really
interesting front set up. what is the car called?

Think it’s the Norris Special based on a Frazer Nash TT Replica.
I saw it at Brooklands and the chain “gearbox” is terrifying.

Mark, I have a front axle which would work for that car which
would be available. It was made for exactly that suspension.

I had a quick go at scaling the Frazer Nash Special, two small
problems! The first is I cannot find a good straight on side
view of the car but I think I can work around this.
The second problem is scaling it off, I haven't got any wheels
yet, Honda wheels seem popular and I took a guess at the outside
diameter of these being 530mm and then scaled the
picture/drawing to suit.
Could anyone confirm the outside diameter of a 17 inch Honda
tyre.
Based on the 530mm OD wheel, it gives a wheel base of 1880mm is
this about right?
Thanks.

Mark, you will struggle to scale the cars and make them work
(and you can't scale you so you won't get in :) ) You are trying
to "capture the spirit" of the original.. Shoot for a wheelbase
of about 66 to 68". If you google Julian Grimwade you may find
more, he uses the car.

If no-one else chimes in with Honda wheel and tyre size I'll
measure my pit bike wheels tomorrow and let you know.
Here's some thoughts in case they're helpful:
As Rhys says, remember to leave enough space for a full-size
person when scaling.
Get your body weight low and forward - to that end you can push
the front of the ck body forward without losing the look and
compress the scuttle (Bill's trick).
Don't make the cockpit too wide - sitting in other people's ck's
will give you the best feel for that.
Think about the packaging of pedals and steering when planning
your body construction - it can end up quite busy at that end!

Thanks for the comments,
Although the cars are not exact replicas, I really need to draw
something up before I start cutting metal. I have found with
other projects if I don't have a decent plan I spend ages in the
workshop scratching my head!
I will try and scale the body and then alter it to accommodate
the Honda engine and driver etc. I think if I try a more free
style approach it will end up looking a bit silly! It sounds
like people alter the length of the bonnet and rear tub to make
things fit.

A tyre 2.25 x 17 measures an OD of 550mm.

Just remembered there’s some info about weights and sizes on the
Bugatti build journal (about page 10).
Pitbike wheel with 3.25 tyre. Diameter 600mm
Pitbike wheel with 2.50 tyre. Diameter 570mm
