1924 Delage GP - a what ?

[Codi]

Love your build and techniques Andrew.  Most certainly following and learning along the way.  cheers, tim

[Pico]

I've found the Acu Stion website but the nearest thing to that honeycomb radiator p/e is something called "radiator panel plate". It does not enlarge enough so that I can see if that is the same product. Is that it? Do they have a US distributor?

[absmiami]

so back a few months ago I was working on the engine bonnet panels ...

now that the radiator shell is attached to the frame I can check the panel fit - which needed a lot of trimming and tweeking - this is a little closer to what I had hoped for

also a lot of work on the frame - but the changes are not as obvious

now I can start to mess around with the driving compartment and the engine bay ...

[absmiami]

the engine is that really cool printed part that I posted at the beginning of this thing

it was designed and printed without crankcase or sump detail - but I am adding this

- as I think this car raced with an engine compartment opening in the undertray

so I filed away the lower portion of the printed engine and sawed up some renshape for the crank case and then I'll make me an engine sump ...

Enjoying this project Andy.

WOW,,,,, just plain WOW.

 

 

[absmiami]

thanks to Bill JC and Tim - fr the middle of Pa .....

Pico - the mesh for the radiator core - is ACS24175  1/24th sc mesh hexagon - mite still be available - check the usual suspects

      don't know where I got mine - I'm sometimes lax about tracking that - if you strike out I'll send you some ....

also going to use "Finisher's"  photo-etched No 11 screen for the engine panel openings

        once again - forgot to market the package with the internet source

- maybe it just floated into my workshop one day a few years ago   -   who knows

anybody seen the announcement for a super/luxury/vintage car show in Miami next February?

as part of the Miami Beach art basel weekend - google Grand Basel car show ...

you'all are invited - or inverted .......

[absmiami]

the engine sump - strips of evergreen plastic mostly

the fins are alternating strips of 0.10 by 0.40  -  and 0.15 by 0.20  -  all liquid glued - this allows for some alignment while the glue sets

[absmiami]

the bolts are resin bits made by Master Club fr Russia

they also make some neat "castle" nuts that I will use on the supension

[absmiami]

wondering of Ryan Reynolds is looking for some additional set designers for Dead Pool III

what do you think ? 

[afx]

Sump looks great.  

[Codi]

Love that pic of your work bench.  As soon as I saw it I burst out laughing as we've all had them look like that at some point.  Nice progress on the car too.  cheers, tim

[absmiami]

wait a minute, Tim - the workbench photo was taken AFTER I had cleaned it up ....

the restored car - you can refer to the engine shots page 1 ....  -  used Zenith carbureters feeding 2 branches of manifolds to the cylinder heads

subsequent cars used super-chargers - as did most other GP cars til the second world war ...

so I am making the manifold pipes - out of renshape - per the pics

time consuming - the first one wasn't quite right - I have to shape the manifolds so that they bend down

- so the carbs do not interfere with the run of the chassis rails

the white pegs are evergreen plastic - .035 - which are stuck into slightly larger holes drilled in the cylinder heads

- the printed engine has accurate ports to locate the holes ...

  

[absmiami]

most of the shaping was done with files made by www.perma-grit.com

these have random toothed surfaces that are much better for working with renshape than regular files

also used some sanding sticks

the initial shaping is done on the renshape "stalks"  - just easier to shape while they are attached ..... 

pic 906 is the third of four that I have to make - this has about the right shape - I'll tweek the others to get close to this ....

the carbs attach to the bottom of these manifolds - there will be some guess work here

- there are no good shots of these carbs as they sit down along the chassis rails - ... 

[absmiami]

time for a small update

thinking about the spark plug wires .....

they are clipped to the plug  tips at a right angle

so I got some photo-etched rings made by Keyser valley models - they seem to cater to train modelers

the rings are quite small - the opening in the ring is about .020

I soldered .013 silver rod through the opening to make the attachment clip -

the ring is then glued into the open end of the plug wire with a 0.7 mill sleeve slipped over to hold the assembly together...

the silver rod will slip into the end of an 0.60 mill tube with a nut - this will be the spark plug ......

using .016 dia plug wires - pretty close to scale accurate

gotta make 12 plug wire "clips"  made 6 so far ...

[absmiami]

If you refer back to the pg 1 photos - there is one pretty good shot of the ignition distributors

- two large assemblies perched on curved perforated trays  at the front of the engine

these are much larger than modern distributors - but they work more or less the same

this was the first racing 12 cyl engine - and although the engine itself was compact - at least for it's time

the distributors certainly were not !

so I'm going to make these from diff size evergreen tube, rod, and strip

the assemblies will be about 4 scale inched wide and 6 scale inches tall

the separate parts will be easier to finish before assembling

hard to see well here - the detail will show much better once these are made and painted.

[absmiami]

the pdf is to celebrate 5,000 hits

leisure time well spent  ( ?? )

been working on the distributors - one for each cyl head -

about one dozen bits and pieces of evergreen in each distributor

next the spark plugs ..... and the plug looms that sit on the valve covers ...

dogfishhead.pdf

[absmiami]

the guides or looms for the pug wires are made from Evergreen tube and rod

with a peg at the base that sits into a .028 hole drilled into the valve cover

the spark plugs are made from .06 mm alu tube and .042 alu nuts fr RB Motion

by using a tube rather than a rod I can insert the wire that is soldered to the end of the plug wire for a secure right angle fit - a little over-scale - but no much ....

each cylinder bank will have three looms and six wires and spark plugs 

[Pico]

Lookin' good.

[Pico]

Wouldn't that distributor cap be bakelite, therefore brown?

[absmiami]

I agree - went back for another look at the engine in the Leno video

it probably is bakelite and is brownish red sort of - gonna have to fix that !

have you ever seen the Figoni bodied  Delahaye at the Rev's museum  ?? 

[Pico]

Haven't seen the Revs F&F Delahaye. Saw and photographed Mullin's two F&F Delahayes when they were on display in the Petersen, several years ago.

[Straightliner59]

Excellent work, Andy! Very cool subject. There's just something about these old race cars...

[absmiami]

oops

where did the summer go ?

will be posting some shots of the summer progress

the plug wires were finished about two months ago

the spark plug ends have silver wire soldered thru the KV eyelets

and I re-painted the distributor caps - something  a bit darker - more like a bake-lite color ...

[absmiami]

now to the engine bulkhead

which is a sandwich of evergreen plastic sheets to create the trim around the edge

which was cut out, glued, and then drilled for some resin rivets fr Russia's Master Club

the black plastic rectangle will be the brass chassis plate ...
