Compound cuts for inlet manifold

[robo]

Eg. if the tube you want is app 6" long and you need compound angle on each end. Cut two bits of tube app 4" long and slit one of the tubes down the middle and open it up so the other tube slides inside like a telescope. You can then fashion the angle one end offer it up to the flange, you can then angle the other end to suit and if slightly out rotate the two pieces and keep dressing the ends till right, you can also alter length to suit on the telescopic bit if you naff up.Tape them together when spot on and copy to a good bit.
