I need to have the flange machined on my Tubular Manifold. In my experience I find that Machine-shops usually moan about being not being able to clamp stuff as their excuse to charge you an arm and a leg. How easy is it to machine a manifold flange? Can I expect to have my pants pulled down?

 

Cost me Ł30 cash at my local machinists.....

.....but I do know someone that paid Ł90 elsewhere cos it fucked a load of their bits! LOL!

 

like you said mate it all depends on how difficult it is to clap down

but imo and engineer worth his salt could make up a tempary jig to hold it ?

on prob you may find is that your running an exteranl wastegate and seeing ur pics it may prove tricky with the extra section of pipe going in diff direction thus making it more awkward ?

it need skimming cos its to thick or purely down to flatness ??

beef

 

i wouldnt expect to pay more than 30-40 quid though regardless

 

my engineering company broke to bits trying to skim my tubular manifold, they said its one of the hardest metals they've had to work with, still only charged me Ł30, and the bits are Ł40 each they said

poor buggers

 

Worse thing / most difficult thing about machining anything is the setup; holding the part securely .... even to the extreme that sometimes custom fixtures are needed to hold parts as there is no other way of doing them.

Guess it depends on the exact design of your manifold, something that can only be judged by actually seeing the part in question.
