Ladder Frame Info
andkilde - 23/1/06 at 01:20 PM
Hello All
I recall romeone here on the board commenting that ladder frames can be constructed with quite acceptable stiffness levels and I was wondering if
anyone had any design resources available for them.
I was at the Henry Ford Museum over the weekend and I'm quite taken with this:
1906 Locomobile racer
The bodywork seems quite simple and there is quite a lot of room in the passenger compartment (I'm a big guy, getting into and out of a seven
isn't pretty).
Was thinking of ditching the leaf spring suspension for something a bit more Locostlike and there's plenty of room under the bonnet for:
GM's Vortec 4200 all alloy straight six
Any thoughts?

Some information in here (section 5):

Hope it helps.
p.s. not sure what the SVA man would say about that external chain drive

Thanks much.
No SVA here in the colonies, and the chain drive is one of the likely victims of the process

That Vortec engine is not pretty. What you want is an older Jaguar straight 6.

Why not build a Ford A-replica? (hot rod
)
The Vortec 4200 does produce its ponies. It isn't a bad engine, I think. Although Chevy small block might be easier.

It'll cost a fortune to fill the tank
akumabito - 23/1/06 at 05:58 PM
nahh, in my opinion if you are going to build a replica, or a car roughly based on such an old design, you should get an engine that looks like it is
from the same era, or it will just look goofy. Straight-six engines just look the part. And of the many straight-six's I think the Jag lump is
one of the best looking. But there are many more 6 cilinder engines. Older BMW engines are also fairly pretty. Chevrolet also has built a ton of
6-cilinder engines...

I'm looking at the modern GM six because they're light, 185 kilos including accessories, powerful 270 hp, 275 ft/lb and self contained,
coupla wires and fuel lines and you're running, no complicated loom to fuss about with. Plus they come in SUV's so you've got soccer
moms all over North America lining up left and right to roll engine donors for you. And, it's got the right bellhousing to fit any number of
decent cheap manual transmissions 4, 5, or 6 speed.
The Jag and iron Chevy lumps are, well, old, heavy, not terribly powerful, and not as plentiful in scrapyards anymore (they've built more than
1,000,000 of these since 02'
.
And FWIW, the chevy and jag motors are also far too modern -- it ought to have a flathead if you're to stick with a period powertrain -- so, in
for a penny, in for a pound as it were.
The bigger question is how do I hang an independent front suspension on this thing in an aesthetically pleasing manner with the axle hanging way out
in front as it is.
PS, thanks much for the Cymtrik's file, it's brilliant.
Cheers, Ted

Ooh...
Thanks for that, looks like he has nice chassis plans available.
Done a bit of photoshopping:
changed wheels, added a bit of rubber, gone from brass to stainless and had a go at changing the chains to trailing arms.
Seeing how much I can modify it until it all goes pear shaped.

Andy,
I think the idea is superb - one of my fave looking cars is the Napier Railton and I'd love to have a go at replicating that (though without the
Napier engine), but I do think you should stick with period wheels - if you need more traction, do what they did in the "olden days" and
have two pairs at the rear.

Brilliant idea!
I love those old racecars.. I think you should keep the brass/copper look though. It looks sexier.
The Railton Napier is damn sexy too... but that thing is huuuuge! Another gorgeous car is the Ronart.. http://www.ronart.co.uk/
Just found this car... isn't she pretty?

Here's an engine
Might be a bit low on hp

No cilinder head...
Simon - 23/1/06 at 11:53 PM
That's ok, we're an innovative lot on here, I'm sure someone could make one
Was your pic taken at Goodwood?

You could perhaps better buy an old fire truck (from the twenties)
Strip it to bare chassis and put your body on it.
Then you have an more period looking car.
iank - 24/1/06 at 01:14 PM
Along those lines there is a blower bentley copy in the UK called the sherpley.
http://www.sherpleymotorcompany.co.uk/Gallery.htm
It uses a small commercial van (sherpa IIRC) for the chassis. No SVA (not that that's a problem for the canucks )
p.s. lived in Vancouver for 4 years (only came back 3 years ago because SWIMBO missed her family 
)

Interesting you mention the firetruck. Jay Leno of US late-night TV, has over 100 "interesting" cars. He now owns... well, see for
yourself. About the engine:
started with a M47 Patton Tank V12 engine (1950-1955) 1800 cu. inches all aluminum - air cooled - overhead cam - Engine alone cost U.S. Govt.
$100,000. to produce in 1955. She takes 17 GALLONS OF OIL - 1000 h.p. - 1500 ft. lbs. of torque.Y E S !
The incredible story is here:

Great link! Looks nice! The bodywork on that car is incredibly simply as well...

Love the 1920s style racer car built by a VSCC member using a Commer TS3 engine

Shame, should have brought the family over to Vancouver -- it's lovely there.
