Hey everyone, I'm new to bike building, but have been welding and fabricating for over 40 years. I'm working on a Warrior trike, and have measured 20 times, and cut once. I'm to the crucial point of fitting the frame together. After cutting the 45 degree V notch in the rear seat tube, and building a wooden jig, for the rest of the frame. With the seat tube on a block 5" off of the ground, the front boom 11 " off of the ground, and the middle boom sitting in between at the 19" mark on the seat boom, I'm coming up with a 48 degree angle between the seat boom and the middle boom. Is this angle acceptable or do I need to make changes to get it exactly at 45 degrees? I'm thinking the 3 degrees is in the seat tube to fork notch.
