Sounds simple, how can I draw two parallel lines along the length of a piece of tube. 2 lines 27mm apart, on some 44mm diameter tube.
Just tell Roy to make a set of zoomies with some bike baffles. Sorted. :tup:Mr Monkey, yes, that'll do. I knew there was a simple solution, I just couldn't see it.
Alan, I am trying to make a better flowing exhaust system for my truck, as you are probably (possibly?) aware they have what's known as a hockey stick exhaust. It runs from number 4 to number 1, then back on itself. In effect the exhaust hits a brick wall, and not at all efficient. The exhaust manifold is a tube, set into a D groove in the head. With the help of Roy the racer, a better flowing system is in the pipeline, and the two 27mm lines are for the top and bottom of the exhaust ports, which are square. I am using a piece of 44 mm tube, to make flanges for each port, then slit lengthways, and a flange and end plates fitted.
Hope that makes sense.
