Building a golf ball return ramp inside of a hitting cage with the center being lower than the sides so that the balls funnel down to the bottom of a collection receptacle . Thinking of bending the pipe that connects the sides as the ramp descends to the bottom. I may need to bend pipe in 3 or 4 spots as it descends to the bottom of the ramp where it will collect the golf balls. I kinda know what fittings that I will need for the sides of the ramp but not sure of the connectors that I will need t o connect the bent pipe to the sides. Any suggestions of other methods would be welcome.
