Stratos Evoluzione, Carbon Kevlar body, T45 spaceframe build

[sean999r]

Profiled cutting A-Pillar tubes was very time consuming, like anything if I did them again I could have made them a better fit and tighter profile, that’s the nature of 1 off’s




No 2nd pair of hands, wire ties towels and clamp
Temporary held tubes in place for tacking




Front Nose and instrument binnacle
are ready for collection
Front Uprights are apparently almost finished
Time to buy more T45 tube

[sean999r]

45mm 3-1 merge header (exhaust manifold) build
In 304 stainless


Measuring the ports they are perfect dimensions for 45mm squashed oval, simple vice then cut them off at 38mm long and repeat



Bit of chamfering on flange and tube, hammer to start finishing with vice to press home square





Only minor work needed make tube mate tight to flange opening

Another amazing new to me Book
chronological pictorial 50 years of Stratos

[sean999r]

Set up steering column / wheel
I took measurements from John Cross Rallycross car, however he sits further rearward than I would
This X1/9 column and wheel which is 360mm
I will use either 350 or 330mm wheel

[sean999r]

Nose arrived with separate inner headlight boxes, ie for me to bond in and received Instrument binnacle housing
Lots of trimming required
Wheel arch trimming will be have to be 1 of the last jobs

[sean999r]

Trimming/ de-flashing on rear of nose around windscreen and door shut area, triple measurements
Cross checks just to get some preliminary reference points for later
Cut out grill opening

This Nose is 3rd version John has,
1. Litton Corse
2. “ “ Grp5 type integral spoiler
3. New wider wheel arch, similar to original early Stratos Marlborough prototypes

3. This is the one I chose 1735mm width, I think most Grp4 are 1710mm

I may order the Grp5 spoiler ? I like the factory 1st Grp5 Stratos prototype spoiler, which I would have to make myself, decide later.

Could/would you go about trimming the wheel arch with a router running off an appropriately shaped curve to guide you? I hope that makes sense.

Definitely could, I do not have 1
Decided to cut my Splitter which I will attach to Nose It will aid easy on - off location to jig
Then I will cut a plywood template for the wheel opening which I can support mount to jig for accurate equal side to side wheel arch profile

[sean999r]

Arr the joys of making Race bodywork fit blend and symmetrical
Getting there, slowly.
Nice bit is having level jig table, though it’s not a ground surface plate, but it’s within 1mm + I have center line makes it easy to see discrepancies and adjust accordingly

Front Nose weighs 11.6 kg easy to pick up and manipulate

There is something about the early prototype cars with the big rear spoiler and distinctive front end.

















If thinking about that route it would certainly be something away from the normal replica fare.

[sean999r]

That early Targa Florio front spoiler is what I’m thinking of making with replaceable lower edge as the latter Grp 5 ran

[sean999r]

Not much to show recently, spent Easter and Coronation weekends fitting headlight boxes, modifying, bonding,laminating into this widened front nose, cut out headlight openings position measurements from LB
eBay special winning bid for Tillet B6F FIA seat arrived today
My car has a raised floor, ie higher ground clearance and no lower sill edge below the GRP body sill
It’s good I’m almost Jockey size 😀
B6F seat is a triple angle curved type seat so it lowers the driver

[sean999r]

Finally after searching got this lovely
Jones ( Moroso branded ) mechanical tach
3 5/8” / 92mm o/d
I will need custom face as I plan to anti clockwise set 90 degrees
It will take pride of place center of dash

[Darkspeed]

Had me thinking there - I first read that as you would be converting to anticlockwise rotation ! Reading again its a new face orientation to move 7500 to the 12 o'clock position.


That seat looks set in so much space......... the reality is so different.

Maybe not quite 90 degrees but close

On the seat I’m trying to get forward as possible,
As pictured that’s the maximum, that seat being so slim as opposed an upholstered one is probably adding to that illusion

It’s sitting too low at the moment, so anyway enough playing with bits of wood blocking, next order FIA weld-in seat rail, seat brackets
Pedal box , thinking of Wilwoods 340-16602 it’s about £150 savings on a Tilton 600 series

Maybe summat like this:


With that well-equipped workshop you have it might not be relevant, but I know that for the Tilton pedal boxes there are multi-hole floor mounts available which might make driving position setup a little easier? Having said that I'm sure you could make your own for the Wilwood." it’s about £150 savings on a Tilton 600 series"

Commercially available multi-hole (guest driver friendly?) pedal box mount

[Darkspeed]

I think I have the same Smiths tacho - BNIB - a replacement for this one!

[sean999r]

90 degrees probably fine just need a custom printed face and loose Moroso

Since I will have to have mounts for pedal box
I could just make a 3 hole adjustment ?
theirs not much room so it’s more likely pedals are fixed, small adjustment on column and seat is probably all I’ll have

This morning stripped down X1/9 steering column, requiring drilling out security screws in the ignition lock, turned out easier than first looked.
In middle of shaft was this welded Lock piece that the ignition engages with, grinder and turn down in lathe, straight shaft now.
I need a removable steering wheel, cut off the original Fiat steering wheel spline then turned down end to create a press fit stub for the new QD spline section




Pressed on ready for welding





Done

On my Steering Column “Mounting Bracket“ all in 4130 chrome moly steel plate
Welded on M8 weld nuts


Wilwood adj ratio Pedal Box ordered.
Seat position with Tillet seat mounts in the forward most position possible for to give max reward adjustment, height set to keep myself lower enough but still able to see over the dash
