I have been busy with a lot of things, in the meantime I did the gearshift (gearbox side) pics will follow... and placed the radiators...
This might be surprising
SO... I machined some spacers to make a Rad Sandwich... these fit the plastic bobbins on the rad, the same system applies to the suspension of the
sandwich.
I prefer it that way hance the small (4mm ish) screws in the plastic are now only in tension instead of in shear like with most :s
Also the plan to put them in the side pontoons got scrapped... pontoons needed to be way to big, so now the'll house the inter- and oilcooler.

The Gear selector... I ended up buidling models up to MK3,
MK1 being direct action... but in the friction/stiction-less world of CAD these things work, in reality it was one big jam.
MK2 being the picture below with a direct acting push/pull for sideways motion and a non rotationally fixed mount for in/out motion.
Because of space restrictions (exhaust) the motrion could nog be lineair ... locked up yet again because of friction and created moment on the gear
shaft... thus binned
MK3 Is this one, using a lever action directly in line of the required force for in/out movement.
Had to lathe a thingy to attach the tie-rod-end center shaft
AND WE STARTED LAMINATING...
Tricking a large part of the family in participating
We started with the "hammock" between the front wheels
Despite using several coats of boat lacquer on the wood model... and sever coats of PVA some parts still bounded 
It was hell getting her out... destroying the model in the process.
For the other models I'll be using my secret weapon.

We continued these last days with laying up the mold on the model of the ´bonnet´.
This one needed a double amount of layers to make it stiff enough..
That meant tapping, tapping and more tapping...
Luckily I have some reinforcements...
In this shot the 'secret weapon' is visible... insulating aly tape
Works a charm, out in 10 minutes
a mirror finish
And even the model survived unscratched this time
And because of the team effort I had to make a task black board... very 6sigma

Today we've build an airscoop mold
It's a real family affair...very thankfull of that! it means we can make a mold in a few hours... the banter, that's free
shouting how things should be done... running in the family

it´s been quite a long while...
my TIG broke down, wtf paid nearly 3000 quid for it only 5 years back ! Been dry+warm stored and only used on the weekend.
Ofc they wouldn´t tell me what was wrong, had to wait 2 moths for the damn repair.
So starting where we left off...
The mold for the nosecone
Hammock mold
making th mold stiffer, as it is quite big. This was a real faff !!! The resin would not stick to the wood and spur bubbles all over, drove me
insane
So this was the result, ugly as fa... but it does the job...
It got to me so bad that I´m splashing cash to do the ´products´by vacuum injection.
And this is thanks to ma genius... an old motorcycle fuel tap now serves as a 3way valve for getting argon to the TIG, the weld piece or both.
Because we're finally tigging the stainless bits
With the help of some lathed wood
This almost doesn't look like a huge bodge
As by magic... Tadaaaa finished
And then I made a new tank out of ally, as the steel one weighed a tonne.
Since I only rarely weld ally I was quite pleased... and then I saw Project binky yesterday... one can only cry
This morning we started demolding the hammock... again a moment of terror... despite using the ally tape making the surface so smooth that even the
PVA cant be polished up because it rubs strait off... and ofc the PVA who's only goal in life is to DEMOLD the damn thing... it would not come
out for sh*t.
Again a model had to be destroyed
3hours of blood sweat tears and curses got it out

some time ago I was asked how I would run the cables, cooling etc in the car.
well, I've created this...
For the water I've chosen to run a pipe through, I had considered running it directly... but didn't trust the fuel acting as an
accumulator.
shifter cables and wires are going through also.
Lately we we're having an itch epidemic, with everybody moaning and scratching S. Holmes came to the conclusion the problem was the wash cycle
in conjuction with GFRP  The culprit was punished to very old fashioned laundry days...

So the tank is in...
I adapted the brace to be bolted... I'm foreseeing a tie rod end connection in the future, but for now...
So the tank rests on the brace and is strapped to it. Sideways movement is halted by little brackets on the frame.
Now just need to paint it and then find some self adhering foamy bits...

So in the meantime a lot of sanding molds...
I really despise doing it, but anyhow not a very informative picture for you guys XD
Tonight finished the gearshift... best throw ever, about 30mm :p
Downside is that the selector needed a bit more stiffness...
The opening is needed to reach the connectors, will give it a think how to stiffen that part. As obviously this is now the weak point
The shifter end... looking at it from behind... remember that the Saab has a rod acting directly upon a shaft while I now have a cable selector...
So I needed to invent this from scratch
A rod end pulls and pushes the shaft via an adapter that als has an arm for the rotary motion.
The push-pull cable for the rotary motion is hung by a pivot as the in/out motion of the shaft is far greater than the cable would allow.

Well, thanks for that photobucket... no new stuff gents.
I have had the worst 2 years of my life...looking for internships trying to graduate.
Monday I have an interview with Prodrive, any help welcome.
Also still without a car since looking to be an (unpaid) intern means little dosh coming my way and it didn't help that the tax regime for the
daily I was doing up went up by a 1000% (no joke) 3 weeks before I finished it, so started from scratch with another daily.
meanwhile the Saab engine has left the shop.
Over the summer the company that made the ECU interfaces for the TRIONIC disappeared, so that meant that for it to run in the Atom I would had to
invest in a standalone ECU thingymabob...
and despite what the guys at MCN say, an Emerald does noet a budget build make.
And the engine was too heavy anyway, since it's becoming abundantly clear that this rotten country will never let me have it on the road.
So it needs to be a 750kg trailer/car combo so I can tow it to the track... leaving about 500kg ish for the car.
So I looked for -and found- the best engine ever made

A rover K
I would like to put bike carbs on it ( multiple reasons) but I guess I'll keep it standard till I get it running

Original Atom was also build with the K-series.
