lets see some 3-1 collector designs.

 

Someone had to post it.

 

split a pipe in 3.

calcul the angle, start with pvc pipe, cheaper and softer on blade...

practice.

dont go to beer after 30 min.

any pics to help explain your method?

 

sorry, no pic's

but it goes like this... 360 / 3 = 120 deg.

this wil be your start angle, now you need to know the longer of the cut you will make, this does depend on lenght of the collector ( 3, 4, 5, 6 inch ) and the spacement you want to have between the tree pipe at the top of the collector.

it's easy man, sit down and get the calculator in hand, you will find it much easier if you plan a bit before you start to cut.

hope this help, practice is the key.

I just wish I could say those words!

Sorry, if this has already been answered, but I didn't understand if it did. How do you calculate the miter angle to make a larger diameter at the bottom. I am assuming there is only one cut per tube, correct?

Two cuts not one.
