Cheers fellas, 
Forgot to add dont use evostick timebond adhesive, It sticks really well and does the job, it just doesnt brush or spread well, had to use loads of the stuff!
Hope you find an AR3 steve, would be awesome if we both got up n running.

Couple of questions to help me if that's ok?
How long did you leave the initial coating before applying the two parts together? 15 mins?
Did you brush or roller the adhesive on?
Did you use any wood strips between the cab and formica to get it in the right place before pushing together?
Did you use a roller to ensure that there were no lumps?

Ben, as above used that evostick stuff, and it was just total gloop, tried a brush, a roller and a spatula and none of them worked effectively! ended up just sort of slapping it on and smearing it about, by the time i'd done that to both sides and achieved good coverage I think about 10-15 mins must have passed. Then I used 4 strips of wood across the cab to rest it on and into position removing one at a time and using a J-roller to apply, there were certainly spots where the adhesive I had applied was thicker then others, but the formica is fairly thick, and with a bit of rollering you cant see any lumps, I picked the j roller up from ebay for a couple of quid and it worked well.
In an ideal world get a second pair of hands to help you lift it onto the cab and get into position, its fairly brittle and the system cab is wide and above 6 foot tall, so it was hairy getting it on without cracking it!

That looks amazing mate. used to love playing super sprint st uni. congrats on the restore looks like it's been a worthwhile effort.
Well since august i've been trying to hunt down parts for this, struck lucky and picked up a full loom from a Klover, a couple of untested AR3 boards, and this finally arrived yesterday:
The CPU and video pcbs are back from Retroclinic all working, got to order some caps and fuses etc but then I can hopefully try and put this all together over the christmas break!

Nice!! Well done on tracking bits down.
Atari bricks are getting difficult to find - mostly I think they only made enough plus just a few extras as the transformer part is a fairly reliable thing.
As a tech project we should have a combined effort on making transformers - they're not incredibly difficult just have to be fairly precise and do a bit of maths.
Often the brick can be the most elusive part.
Looking forward to more progress.....

There are some photo's on this link here, so you can see how far its come on. Pics might help you power brick/wiring etc.

I'll go have a look see if I can ID anything in boxes.

Having to wire this one from scratch and some parts arrived earlier in the week so finally got around to looking at the power brick. Although this is a champ sprint cab, it will be wired as a paperboy as
thats the power brick I have, both boards have the same voltages but
seem to have very different ways of getting there, so its a bit of a mission, but so far i've swapped the voltage selector over to 240v, and made up two of the missing molex connectors.
Here are the readings so far:
Can the arcade techs have a look and let me know if these are acceptable range wise? the 125 and 130 seem a little high?
Stopping for tonight and will try and get some more done tomorrow.
