If you were to make up a ladder chassis like in this picture, what grade of steel plate would be best to use?
thanks

A simple question really.

Sorry - don't know the answer (nothing new there then!)... are you making a new chassis for the Falcon or making something new?
Id hav thought normal mild steel would be ok. frame rails for a 30s ford?
looks like 3mm?

Land Rover chassis is made from 3mm steel. Dont know the grade.
A LOT will depend on what you are doing with it, and the stress / strain, engine power, torque, how much cross bracing, etc etc.
Have a look at:
http://www.designa-chassis.co.uk/company.asp
Std is 3mm, and heavy duty is 4 or 5mm!!
I had one of his chassis, and it was no problem at all.
Might be worth giving Iain at Designachassis a call. Nice bloke from memory.
I hope this is of use.

At first I was looking at using an extended Range Rover chassis but there’s an number of problems, one is the front doesn’t taper
sufficiently to meet the narrow radiator grill so the chassis rails would stick out under the wings and second the kick ups front and back are very
small which they need to be on a Land Rover to get the ground clearance but would make a saloon car too tall. By the time I’d altered the chassis I
might have well just made a new one that was correct from the start. I haven’t ruled out it having 4wd as I’d like that if possible Most of that there is the jig for carrying the two rails. The chassis itself doesn't look that substantial but it has a lot of rhs reinforcing inside it before it's boxed in. The sides of the rails look like they are cut from a big sheet so it's going to be an expensive project whatever it's made of.
I'd use 3mm 1020 plate. The strength is from the section height, not the material thickness itself.

ehem no thanks that looks hideous
I think? perhaps its just the low screen, certainly never thought of doing that...hmm

no, that does look hideous, your first instincts were correct
Mild steel (st37) should be all right.
You'd better off buying a Panther Royale
There is also a book written in the 70/80 about designing your own car. In this book the writer describes the process of designing and building a 4
seater torpeod (a la Panter Royale) with Jaguar XJ parts and a steel ladder frame transformed into a semi monocoque.
I cannot find the exact title.
Do you have any further details about this project (engine, gearbox, suspension, tyres?)
You really got me thinking.
Firstly, to get the proportions of the Bugatti Type 41 Park ward is very hard with modern (affordable) mechanicals. The wheels of the bug are
24"!
With 15 or 16" rims it is hard to match the proportions (and still have any usable interior space)
I would suggest to have a look a the sports saloons that were build in the late thirties.
The proportions of these cars are easier to capture.
So my plan would be (just a suggestion):
running gear: Ford Cortina/ Sierra/ BMW E30/36/ Triumph TR
This would enable to have a track around 1,4m (+/- 5%) and the final touch would be 205/70R15 tyres to get the correct wheel diameter.
These cars offers also plenty of engine choices.
The wheelbase should end around 290cm /- 5%).
For the chassis I would use 100x50x3mm section. The rear section should kick up 20cm and the front section would have 10cm step.
The body would be constructed from 25x25x1.5mm sections with 16swg steel plate (also used for the floor). Interior space would be around 2 metres long
120cm high and 135cm wide.
Perhaps put some integrated rollcage (50x2.5mm?) for safety.
The other dimensions are:
length: 4,5m
width: 1,7m
height: 1,45m
Sofar my 0.5 cents
SPAM!
Nice starting to develop further on (IMHO)
Off to bed! (Should be already two hours in it actually
)

Cheers that was an interesting reply.
My current plans are slightly different from you. I was intending on using a ford 2.8 v6 petrol which I have a very low mileage example and a good
gearbox for it too. To help keep the running cost down it was going to be converted to LPG, a kit is available for just this engine and would get me
the equivalent of 40mpg & 150bhp. Body is to be made carved from blue foam laid up on either side with GRP and the whole thing will incase a 8
point roll cage that will also serve as the seatbelt mounts. Not sure about the axles right now, they may be van ones to get the width I need and the
dropped front axle.
