i have 5 pieces of 4' steel 1X1 1/2 steel and i need to build a target stand for this weekend to go shooting

i have a basic idea what i want it to look like but i need some help

i want to build it like an A frame but i need to figure out how to the steel pieces of retangular tube to meet with the center cross bar i figure i need to cut it like this / \ so that way i can weld them to the crossbar.. any tips on how to do that i just tried and it seems i need the angle cut to be extreme to get it to weld together.
