Compound cuts for inlet manifold

[rapidtornado]

Just a little tip, using the same method as the last post, use a jig excatly as shown but to 'tweek' the tubes and get them to the right angle try using pipe lagging which can be cut and played with until you get the angles right then wrap a bit of paper around the lagging cut it flush with the end and then transfer the profile to your pukka tube

That's what I've done in the past

I plan to make mine with plasticlne/ play dough then wrapping with stiff paper and transferring to the tube to cut. One question though --does the tube need to be ROUND -Im thinking about using box section !

er i would start buy cuting one tube over length and manual cutting it to suit starting with cyl 2+3 then making 1+4 as thay would be at more of an angle.
if your miging it a gap will not be a problem

Thanks Guys, I have done roughly what BAZ-R said. I made a jig to hold the top and bottom flanges in place then cut the horizonal angles I know and then made the tubes too long then offerred them up and sawed and filed until good fit. I have one tube left to complete and will post a photo when finished.

many thanks for all your suggestions
