Brief Description: Using a Fitting String to create angles of inciden
In order to get the proper angle on the end of a tube, I stretched a string across the opening and secured it with blue tape. Then using a T-bevel, adjusted to the appropriate angle. These types of tubes are very tricky because there is no real easy way to insert them without having to move another tube. Fortunatelay I didn't have to undo any tack welds. Just think ahead about 10 steps and it will work out.
