quenching in water straight after each weld. Warping was kept to a minimum
Steve, were you part of the A-Team?
Your garage sounds full of great stuff for mercenaries.
Heat is not a bad thing for distortion, provided it's evenly distributed.
And I agree, how do manufacturers let crap out the door. Easily actually, it's always someone else that makes them, and it's always their fault.
A nice sharp file is surpisingly effective.
Edited to add:
shouldn't need to be 'critical' as that's what the gaskets are for

stevieturbo... I just get a pub bottle swapped for ten quid.. dont really want to spend £100 a year on gas.. when I can just spend 20 /30 for bottles... Id never use small bottles.. I have one sat inside the welder which is pure argon.... and have a small regulator just on the off chance that I may run out and need to do some welding.. (as halfords sell the bottles... as do b&q etc...) just cant get a decent flow with them bottles.. ok for a small mig.. but my 230A industrial one.. nah.

There is obviously the rental whcih cant be avoided, but unless you are doing a lot of welding, the bottle could easily last over a year. When I bought my mig, I bought it with a big roll of wire, thinking I would use a lot...it lasted me over 3 years..lol
Depends how much welding you do, I dont do a lot, and would just not be annoyed with small bottles. When I want to weld, I want the gas sitting there ready for me ( as it may be at 4 in the morning... )

I dont do that much.. 1 big reel lasts me about a year.. using 0.6wire at the mo as its mainly car bodywork...
Dont get me wrong... I couldnt use small bottles.... the regulator is there just incase... as small bottles are easier to find on a sunday evening at 8.00... A pub bottle is only about 10cm dia though.. still 1m high though...
Might have to rent a bottle... Now I need to find a cheap source of NO2 now.

Back now...but still no news 
hopefully I'll get hold of the man with the engine out and the pipe later on today...it's taking far too long to get this sorted, sorry chaps

Picked up the prototype uppipe earlier, after trial fitting it to an engine at last It's ish ok, the mounting brackets need adjusting to make sure it fits, but that is possible with the manifold off, and I suspect that this should be done anyway looking at the way they fit.
Welding bolts or nuts onto the flanges is a bad idea we decided because if you have a problem later on with a stripped thread then you'll never get them out to replace I'm going to ask about helicoiling the first batch of flanges...but I expect this will add cost...I'll check...

Paul, I don't think it will be too much trouble for them to weld on a lug which you could then drill and tap at leisure 
I'll start ordering on Monday can anyone interested drop me an e-mail off line with their contact details (e-mail, phone and delivery address), I'll then give you my address to send the cheques to.
Right off to Elvington I go

Guys, probably stupid question, but here I go ...
Would it help fitting stiffer engine mounts ? (Proflex or what have you) OK, I can imagine more noise (NVH) etc... but it would keep the engine more "in place" hence maybe not nececitating a flex joint. (Less movement of engine alltogether)
Dumb idea ?

J, I could count on you to trash my idea.
But hold on you turnip... the manifold & uppipe are connected to the engine... surprise there eh BUT ... also connected to the turbo, which is connected to the downpipe, which is connected to the gearbox, and the gearbox is ... tada ... connected to the engine.
So, puh

not such a stupid idea, as the downpipe's connected to the, turbo, the turbo's connected to the, uppipe, the uppipe's connected to the headers and that's way of the scoob.
But, the downpipe is also connected to the body, so reducing enigne movement should reduce forces on turbo and uppipe. By how much it difficult to tell.

Umm, where's the downpipe connected to the body? as far as I remember it's only attached to the turbo and the gearbox...then via a flexible joint to the rest of the exhaust systems wihich is suspended on rubbers mounted to the body...
